philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 4 analog transceivers these transceivers interface directly to the usb cables through some termination resistors. they are capable of transmitting and receiving serial data at both afull speedo (12 mbit/s) and alow speedo (1.5 mbit/s) data rates. hub repeater the hub repeater is responsible for managing connectivity on a per packet basis. it implements packet signaling connectivity and resume connectivity. low speed devices can be connected to downstream ports since the repeater will not propagate upstream packets to downstream ports, to which low speed devices are connected, unless they are preceded by a preamble pid. end of frame timers this block contains the specified eof1 and eof2 timers which are used to detect loss-of-activity and babble error conditions in the hub repeater. the timers also maintain the low-speed keep-alive strobe which is sent at the beginning of a frame. general and individual port controller the general and individual port controllers together provide status and control of individual downstream ports. via the i 2 c-interface a microcontroller can access the downstream ports and request or change the status of each individual port. any change in the status or settings of the individual port will result in an interrupt request. via an interrupt register, the servicing microcontroller can look up the downstream port which generated the interrupt and request its new status. any port status change can then be reported to the host via the hub status change (interrupt) endpoint. pll a 12 mhz to 48 mhz clock multiplier pll (phase-locked loop) is integrated on-chip. this allows for the use of low-cost 12 mhz crystal. emi is also minimized due to lower frequency crystal. no external components are needed for the operation of the pll. bit clock recovery the bit clock recovery circuit recovers the clock from the incoming usb data stream using 4x over-sampling principle. it is able to track jitter and frequency drift specified by the usb specification. philips serial interface engine (psie) the philips sie implements the full usb protocol layer. it is completely hardwired for speed and needs no firmware intervention. the functions of this block include: synchronization pattern recognition, parallel/serial conversion, bit stuffing/de-stuffing, crc checking/generation, pid verification/generation, address recognition, handshake evaluation/generation. memory management unit (mmu) and integrated ram the mmu and the integrated ram is used to handle the large difference in data rate between usb, running in bursts of 12 mbit/s and the i 2 c interface to the microcontroller, running at up to 1 mbit/s. this allows the microcontroller to read and write usb packets at its own speed through i 2 c. i 2 c slave interface this block implements the necessary i 2 c interface protocol. a slave i 2 c allows for simple micro-coding. an interrupt is used to alert the microcontroller whenever the PDIUSBH11A needs attention. as a slave i 2 c device, the PDIUSBH11A i 2 c clock: scl is an input and is controlled by the microcontroller. the i 2 c interface can run up to 1 mbit/s. softconnect ? the connection to the usb is accomplished by bringing d+ (for high-speed usb device) high through a 1.5 k w pull-up resistor. in the PDIUSBH11A, the 1.5 k w pull-up resistor is integrated on-chip and is not connected to v cc by default. similarly, the 15 k w pull-down resistors are integrated on-chip and are not connected to gnd by default. the connection of the internal resistors to vcc or gnd is established through a command sent by the external/system microcontroller. this allows the system microcontroller to complete its initialization sequence before deciding to establish connection to the usb. re-initialization of the usb bus connection can also be affected without requiring the pull out of the cable. the PDIUSBH11A will check for usb vbus availability before the connection can be established. vbus sensing is provided through ocurrent_n pin. see the pin description for details. sharing of vbus sensing and overcurrent sensing can be easily accomplished by using vbus voltage as the pull-up voltage for the open drain output of the overcurrent indication device. it should be noted that the tolerance of the internal resistors is higher (30%) than that specified by the usb specification (5%). however, the overall v se voltage specification for the connection can still be met with good margin. the decision to make use of this feature lies with the users. softconnect ? is a patent pending technology from philips semiconductors. goodlink ? good downstream usb connection indication is provided through goodlink ? technology. when the port is enabled and there is at least one valid upstream traffic from the port, the led indicator will be on. the led indicator will blink on every valid upstream traffic. a valid upstream traffic is defined as traffic with a good sop and terminated by a good eop. during global suspend, all leds will be off. this feature provides a user-friendly indicator on the status of the hub, the connected downstream devices and the usb traffic. it is a useful field diagnostics tool to isolate the faulty equipment. this feature helps lower the field support and the hotline costs.

philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 6 pin description the PDIUSBH11A has two modes of operation. the first mode (mode 0) configures the pins dnx_gl_n for goodlink ? led indication. the second mode (mode 1) configures the led pins as per port overcurrent condition pins. an overcurrent condition on any port can b e uniquely identified in mode 1. however, all downstream ports are disabled as a result of a single overcurrent condition. in addition to the two modes of operation, the PDIUSBH11A can also be configured to take either a 48 mhz crystal oscillator (for backward compatibility to pdiu sbh11) or a 12 mhz crystal. the internal 4x clock multiplier pll will be activated when 12 mhz input xtal mode is selected. also, the output clock frequenc y is now programmable rather than fixed to 12 mhz. the output clock frequency can be programmed through the set mode command. all these new features are added while maintaining backward compatibility to the pdiusbh11 through test2 and test1 pins. test2 test1 mode input xtal frequency (mhz) output clock frequency (at reset) 00 mode 0 (goodlink ? ) 48 12mhz 01 mode 0 (goodlink ? ) 12 4 mhz 10 mode 1 (individual overcurrent) 12 4 mhz 11 mode 1 (individual overcurrent) 48 12 mhz note: 1. pin test3 should always be connected to ground at all times. pin configuration 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 test1 test2 test3 reset_n gnd xtal1 xtal2 v cc ocurrent_n / ocurrent2_n * switch_n suspend dn2_gl_n dn3_gl_n / ocurrent3_n * dn4_gl_n / ocurrent4_n * clkout dn5_gl_n / ocurrent5_n * int_n sda scl gnd dn5_dp dn5_dm dn4_dp dn4_dm dn3_dp dn3_dm dn2_dp dn2_dm agnd av cc up_dp up_dm dual in-line package sv01047 note: pins 10, 14, 15, and 16 show alternative pin functions, depending on mode of operation (mode 0 or mode 1) as described in pin description .

philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 9 application diagram i 2 c goodlink ? led power switch and overcurrent circuit 5v switched 5v h11a m c clkout 12mhz usb downstream usb upstream 3.3v sv00840 i 2 c interface the i 2 c bus is used to interface to an external microcontroller needed to control the operation of the hub. for cost consideration, the target system microcontroller can be shared and utilized for this purpose. the PDIUSBH11A implements a slave i 2 c interface. when the PDIUSBH11A needs to communicate with the microcontroller it asserts an interrupt signal. the microcontroller services this interrupt by reading the appropriate status register on the PDIUSBH11A through the i 2 c bus. (for more information about the i 2 c serial bus, refer to the i 2 c handbook , philips order number 9397 750 00013). the i 2 c interface on the PDIUSBH11A defines two types of transactions: 1. command transaction a command transaction is used to define which data (e.g., status byte, buffer data, ...) will be read from / written to the usb interface in the next data transaction. a data transaction usually follows a command transaction. 2. data transaction a data transaction reads data from / writes data to the usb interface. the meaning of the data is dependent on the command transaction which was sent before the data transaction. two addresses are used to differentiate between command and data transactions. writing to the command address is interpreted as a command, while reading from / writing to the data address is used to transfer data between the PDIUSBH11A and the controller. address table type of address physical address (msb to lsb) command 0011 011 (binary) data 0011 010 (binary) protocol an i 2 c transaction starts with a start condition, followed by an address. when the address matches either the command or data address the transaction starts and runs until a stop condition or another start condition (repeated start) occurs. the command address is write-only and is unable to do a read. the next bytes in the message are interpreted as commands. several command bytes can be sent after one command address. each of the command bytes is acknowledged and passed on to the memory management unit inside the PDIUSBH11A. when the start condition address matches the data address, the next bytes are interpreted as data. when the rw bit in the address indicates a `master writes data to slave' (=`0') the bytes are received, acknowledged and passed on to the memory management unit. if the rw bit in the address indicates a `master reads data from slave' (=`1') the PDIUSBH11A will send data to the master. the i 2 c-master must acknowledge all data bytes except the last one. in this way the i 2 c interface knows when the last byte has been transmitted and it then releases the sda line so that the master controller can generate the stop condition. repeated start support allows another packet to be sent without generating a stop condition. timing the i 2 c interface in the PDIUSBH11A can support clock speeds up to 1mhz.

philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 11 command descriptions command procedure there are four basic types of commands: initialization, data, hub specific, and general commands. respectively, these are used to initialize the hub and embedded function; for data flow between the hub, embedded function, and the host; some hub specific commands for controlling individual downstream ports; and some general commands. initialization commands initialization commands are used during the enumeration process of the usb network. these commands are used to enable the hub and embedded function endpoints. they are also used to set the usb assigned address. set address / enable command : d0h (hub), d1h, d2h, d3h, (embedded functions) data : write 1 byte this command is used to set the usb assigned address and enable the hub or embedded functions respectively. the hub powers up enabled and needs not be enabled by the firmware at power up initialization. 76 54 32 0 1 0 0 power on value address enable sv00825 00 00 00 address the value written becomes the address. enable a `1' enables this function. set endpoint enable command : d8h data : write 1 byte the hub's interrupt endpoint and the embedded functions generic endpoints can only be enabled when the corresponding hub/function is enabled via the set address/enable command. sv00841 76 5432 0 1 0 0 power on value embedded function 1 generic endpoints 00 xx xx reserved embedded function 7 generic endpoints hub's interrupt endpoint embedded function 6 generic endpoints hub's interrupt endpoint a value of `1' indicates the hub's interrupt endpoint is enabled. embedded function 1 generic endpoint a value of `1' indicates the embedded function 1 generic endpoints are enabled. embedded function 6 generic endpoint a value of `1' indicates the embedded function 6 generic endpoints are enabled. embedded function 7 generic endpoint a value of `1' indicates the embedded function 7 generic endpoints are enabled.
philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 12 set mode command : f3h data : write 2 bytes the set mode command is followed by two data writes. the first byte contains the configuration byte values. the second byte is the clock division factor byte. configuration byte sv00842 power on value remote wakeup no lazyclock clock running debug mode softconnect ? connect downstream resistors non-blinking leds 76 54 32 0 1 1 0 11 00 10 embedded function mode remote wakeup a `1' indicates that a remote wakeup feature is on. bus reset will set this bit to `1'. no lazyclock a `1' indicates that clkout will not switch to lazyclock. a `0' indicates that the clkout switches to lazyclock 1ms after the suspend pin goes high. lazyclock frequency is 30 khz ( 40%). the programmed value will not be changed by a bus reset. clock running a `1' indicates that the internal clocks and pll are always running even during suspend state. a `0' indicates that the internal clock, crystal oscillator and pll are stopped whenever not needed. to meet the strict suspend current requirement, this bit needs to be set to `0'. the programmed value will not be changed by a bus reset. debug mode a `1' indicates that all errors and anakingo are reported and a `0' indicates that only ok and babbling are reported. the programmed value will not be changed by a bus reset. softconnect ? a `1' indicates that the upstream pull-up resistor will be connected if vbus is available. a `0' means that the upstream resistor will not be connected. the programmed value will not be changed by a bus reset. connect downstream resistors a `1' indicates that downstream resistors are connected. a `0' means that downstream resistors are not connected. the programmed value will not be changed by a bus reset. non-blinking leds a `1' indicates that goodlink ? leds will not blink when there is traffic. leave this bit at `0' to achieve blinking leds. the programmed value will not be changed by a bus reset. embedded function mode a `1' indicates single embedded function mode. a `0' indicates multiple (3) embedded function mode. see endpoint descriptions for details. the programmed value will not be changed by a bus reset. clock division factor byte sv00843 76 54 32 1 1 1 0 power on value for 48mhz input 00 00 xx 11 10 11 xx power on value for 12mhz input clock division factor reserved clock division factor the value indicates clock division factor for clkout. the output frequency is 48 mhz/(n+1) where n is the clock division factor. when the 48mhz input crystal frequency is selected, the reset value is 3. this will give a default output frequency at clkout pin of 12 mhz, thus maintaining backward compatibility to the pdiusbh11. when the 12 mhz input crystal frequency is selected, the reset value is 11. this will produce the lowest output frequency of 4 mhz which can then be programmed up by the user. the PDIUSBH11A design ensures no glitching during frequency change. the programmed value will not be changed by a bus reset.
philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 13 data flow commands data flow commands are used to manage the data transmission between the usb endpoints and the monitor. much of the data flow is initiated via an interrupt to the microcontroller. the microcontroller utilizes these commands to access and determine whether the endpoint fifos have valid data. read interrupt register command : f4h data : read 2 bytes interrupt register byte 1 sv00844 power on value endpoint index 4 endpoint index 5 endpoint index 6 endpoint index 7 76 54 32 0 1 0 0 00 00 00 endpoint index 1 (hub control in) endpoint index 2 endpoint index 3 endpoint index 0 (hub control out) interrupt register byte 2 sv00845 power on value endpoint index 12 endpoint index 13 bus reset reserved 76 54 32 0 1 0 0 00 00 x0 endpoint index 9 endpoint index 10 endpoint index 11 endpoint index 8 this command indicates the origin of an interrupt. a `1' indicates an interrupt occurred at this endpoint. the bits are cleared by reading the endpoint status register through read endpoint status command. after a bus reset an interrupt will be generated and bit 6 of the interrupt register byte 2 will be `1'. [in the pdiusbh11, the bus reset event is indicated by the absence of a `1' in any bit of the interrupt register. note that the backward compatibility is still maintained because in the pdiusbh11, the interrupt register byte 2 does not exist.] the bus reset interrupt is internally cleared by reading the interrupt register. a bus reset is completely identical to the hardware reset through the reset_n pin with the sole difference of interrupt notification. the hub interrupt endpoint is handled internally by the PDIUSBH11A hardware without the need of microcontroller intervention. select endpoint command : 00-0dh data : optional read 1 byte the select endpoint command initializes an internal pointer to the start of the selected buffer. optionally, this command can be followed by a data read, which returns `0' if the buffer is empty and `1' if the buffer is full. 76 54 32 x 1 0 0 power on value full/empty reserved xx xx xx sv00831 full/empty a `1' indicates the buffer is full, `0' indicates an empty buffer. read last transaction status command : 404dh data : read 1 byte the read last transaction status command is followed by one data read that returns the status of the last transaction of the endpoint. this command also resets the corresponding interrupt flag in the interrupt register, and clears the status, indicating that it was read. this command is useful for debugging purposes. since it keeps track of every transaction, the status information is overwritten for each new transaction. power on value data receive/transmit success error code (see table) setup packet data 0/1 packet previous status not read 76 54 32 0 1 0 0 00 00 00 sv00832 data receive/transmit success a `1' indicates data has been received or transmitted successfully. error code see table 3, error codes. setup packet a `1' indicates the last successful received packet had a setup token (this will always read `0' for in buffers. data 0/1 packet a `1' indicates the last successful received or sent packet had a data1 pid. previous status not read a `1' indicates a second event occurred before the previous status was read.

philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 15 set endpoint status command : 404dh data : write 1 byte a stalled control endpoint is automatically unstalled when it receives a setup token, regardless of the content of the packet. if the endpoint should stay in its stalled state, the microcontroller can re-stall it. when a stalled endpoint is unstalled (either by the set endpoint status command or by receiving a setup token), it is also re-initialized. this flushes the buffer and if it is an out buffer it waits for a data 0 pid, if it is an in buffer it writes a data 0 pid. even when unstalled, writing set endpoint status to `0' initializes the endpoint. 76 54 32 x 1 0 0 power on value stalled reserved xx xx xx sv00834 stalled a `1' indicates the endpoint is stalled. acknowledge setup command : f1h data : none the arrival of a setup packet flushes the in buffer and disables the validate buffer and clear buffer commands for both in and out endpoints. the microcontroller needs to re-enable these commands by the acknowledge setup command. this ensures that the last setup packet stays in the buffer and no packet can be sent back to the host until the microcontroller has acknowledged explicitly that it has seen the setup packet. the microcontroller must send the acknowledge setup command to both the in and out endpoints. hub commands hub commands are used to report connectivity and power status between the hub and the host. these commands allow the host to enable each port individually and get any change of status such as new connectivity information. clear/set port feature command : e0e3h (clear) and e8hebh (set) data : write 1 byte the data written in the data phase is the feature code described in table 4. when the controller receives a set feature or a clear feature request, there are two possibilities: the request applies to port 1, the embedded port. in this case the request should be handled internally by the controller. if the request applies to ports 2 through 5, the controller should translate the request into a set feature or clear feature command towards the PDIUSBH11A. when the PDIUSBH11A is configured in mode 0, there is only one power switch output and one overcurrent input. this means that the f_port_power and c_port_overcurrent features are not port specific. for these features, any of the set / clear feature commands can be used. the specific port assignment is ignored. when the PDIUSBH11A is configured in mode 1, there is still only one power switch output but there are four individual overcurrent input pins corresponding to each port. this means that the f_port_power feature is port specific and the c_port_overcurrent feature is not port specific. setting the f_port_power feature turns the power on when it is off and turns the overcurrent detection on only when the power is already on. this allows to have a short period of overcurrent condition at the moment that power is switched on. for this reason, the f_port_power feature needs to be set twice. clearing this feature turns both the power and the overcurrent detection off. table 4. data written in data phase feature feature code set clear f_port_enable 0 enables a port disables a port f_port_suspend 1 suspends a port resumes a port fc_port_reset 2 resets a port clears a port reset change bit f_port_power 3 powers all ports unpowers all ports c_port_connection 4 clears a port connection change bit c_port_enable 5 clears a port enable change bit c_port_suspend 6 clears a port suspend change bit c_port_overcurrent 7 clears a port (mode 1) or hub (mode 0) overcurrent change bit
philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 16 get port status command : e0he3h data : read 1 or 2 bytes the get port status command can be followed by one or two data reads. the first byte returned contains the port status. the second byte returned is the port status change byte. port status byte sv00846 power on value connect enabled suspend overcurrent reset power low speed 76 54 32 0 1 0 0 00 00 x0 reserved connect a `1' indicates that a device is connected on this port of the hub. enabled a `1' indicates that this port is enabled. suspend a `1' indicates that this port is suspended. overcurrent a `1' indicates that overcurrent condition exists on this port. in mode 0 of operation, this bit is the same for all ports. in mode 1, individual port overcurrent indication is possible. reset a `1' indicates that bus reset on this port is in progress. when reset is completed (nominal duration of 10 ms), this bit indicates a `0'. power a `1' indicates that power is supplied to downstream ports. since the PDIUSBH11A supports gang mode power switching, this bit is the same for all ports. low speed a `1' indicates that low speed device is connected to this port. this bit is only valid when connect bit is a `1'. port status change byte the description for the port status change byte is similar to the port status byte except that the value of the bits are `1' only when a change has occurred. sv00847 power on value connect enabled suspend overcurrent reset 76 54 32 0 1 0 0 00 x0 xx reserved set status change bits command : f7h data : write 1 byte for assembling the hub's status change register, the device needs some additional information from the controller, i.e. the local power status change bit and the embedded function status change bit. these are provided by the set status change bits command. this command is always followed by one data write which contains the local power status change bit at the lsb and the embedded function status change bit at position 1. all other bits should be 0. sv00848 76 54 32 0 1 0 0 power on value local power embedded function 1 00 xx xx reserved embedded function 6 embedded function 7
philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 17 general commands send resume command : f6h data : none sends an upstream resume signal for 10 ms. this command is normally issued when the device is in suspend. the resume command is not followed by a data read or write. the PDIUSBH11A automatically sends a resume command when an event occurs downstream. read current frame number command : f5h data : read one or two bytes this command is followed by one or two data reads and returns the frame number of the last successfully received sof. the frame number is returned least significant byte first. 76 54 32 x 1 x 0 least significant byte xx xx xx 76 54 32 x 1 x 0 most significant byte xx xx xx sv00835 embedded function the usb host sees no difference between the embedded function and a function connected to one of the downstream ports. some of the port commands sent by the host must be handled appropriately by the embedded function to appear as any other downstream port. the microcontroller maintains a series of status and status change bits for the embedded function as described in the get port status command section. from these bits, the status change bit for the embedded function is derived (i.e. the port specific status change bits). this status change bit is then provided to the PDIUSBH11A by the set status change bits command. host requests setfeature port_reset reinitialize the embedded function and set the reset change bit to indicate that the reset has completed. reset the enable status bit, enable the embedded function and set its address to 0 by the set embedded function address / enable command. disable the embedded function interrupt endpoint by the set endpoint enable command. setfeature port_enable enable the function by the set embedded function address / enable command. set the enable status bit. setfeature port_suspend disable the function by the set embedded function address / enable command. reset the enable status bit and set the suspend status bit. clearfeature port_enable disable the function by the set embedded function address / enable command. reset the enable status bit. clearfeature port_suspend enable the function by the set embedded function address / enable command. set the enable status bit, reset the suspend status bit; set the resume status change bit to indicate that the resume has completed. clearfeature any change indicator clear the corresponding status change bit. babbling condition when the embedded function causes a babbling condition, the function is automatically disabled by the PDIUSBH11A. as soon as the microcontroller detects the babbling error, it must set the enable status change bit and reset the enable status bit. remote wakeup there are three scenarios when a remote wakeup can occur. the following describes the course of actions for each of the cases: 1. the device is not suspended and the embedded port is suspended: enable back the function by setting the enable bit in the set address/enable register and update the following status bits in the microcontroller program: reset the suspend status bit, set the enable status bit and set the suspend status change bit. 2. the device is suspended and the embedded port is suspended: send an upstream resume using the send resume command, enable back the function by setting the enable bit in the set address/enable register and update the following status bits in the microcontroller program: reset the suspend status bit, set the enable status bit and set the suspend status change bit. 3. the device is suspended and the embedded port is enabled: send an upstream resume using the send resume command.

philips semiconductors product specification PDIUSBH11A universal serial bus hub 1999 jul 22 26 soldering introduction this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our adata handbook ic26; integrated circuit packageso (document order number 9398 652 90011). there is no soldering method that is ideal for all ic packages. wave soldering is often preferred when through-hole and surface mount components are mixed on one printed circuit board. however, wave soldering is not always suitable for surface mount ics, or for printed-circuit boards with high population densities. in these situations, reflow soldering is often used. through-hole mount packages s oldering by dipping or by solder wave the maximum permissible temperature of the solder is 260 c; solder at this temperature must not be in contact with the joints for more than 5 seconds. the total contact time of successive solder waves must not exceed 5 seconds. the device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (t stg(max) ). if the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. m anual soldering apply the soldering iron (24 v or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. if the temperature of the soldering iron bit is less than 300 c, it may remain in contact for up to 10 seconds. if the bit temperature is between 300 and 400 c, contact may be made for up to 5 seconds. surface mount packages r eflow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, infrared/convection heating in a conveyor-type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds, depending on heating method. typical reflow peak temperatures range from 215 250 c. the top-surface temperature of the packages should preferably be kept below 230 c. w ave soldering conventional single-wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems, the double-wave soldering method was specifically developed. if wave soldering is used, the following conditions must be observed for optimal results: ? use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. ? for packages with leads on two sides and a pitch (e): larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. ? for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement, and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive has cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. m anual soldering fix the component by first soldering two diagonally-opposite end leads. use a low-voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
