[2] all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . [3] these transparent plastic packages are extremely sensitive to re?ow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared re?ow soldering with peak temperature exceeding 217 c 10 c measured in the atmosphere of the re?ow oven. the package body peak temperature must be kept as low as possible. table 123: suitability of surface mount ic packages for wave and re?ow soldering methods package [1] soldering method wave re?ow [2] bga, htsson..t [3] , lbga, lfbga, sqfp, ssop..t [3] , tfbga, vfbga, xson not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable [4] suitable plcc [5] , so, soj suitable suitable lqfp, qfp, tqfp not recommended [5] [6] suitable ssop, tssop, vso, vssop not recommended [7] suitable cwqccn..l [8] , pmfp [9] , wqccn..l [8] not suitable not suitable

[5] if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. [6] wave soldering is suitable for lqfp, qfp and tqfp packages with a pitch (e) larger than 0.8 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. [7] wave soldering is suitable for ssop, tssop, vso and vssop packages with a pitch (e) equal to or larger than 0.65 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. [8] image sensor packages in principle should not be soldered. they are mounted in sockets or delivered pre-mounted on ?ex foil. however, the image sensor package can be mounted by the client on a ?ex foil by using a hot bar soldering process. the appropriate soldering pro?le can be provided on request. [9] hot bar soldering or manual soldering is suitable for pmfp packages. 19. abbreviations 20. references [1] universal serial bus speci?cation rev. 2.0 [2] enhanced host controller interface speci?cation for universal serial bus rev. 1.0 [3] open host controller interface speci?cation for usb rev. 1.0a [4] pci local bus speci?cation rev. 2.2 [5] pci bus power management interface speci?cation rev. 1.1 table 124: abbreviations acronym description cmos complementary metal-oxide semiconductor did device id eeprom electrically erasable programmable read-only memory ehci enhanced host controller interface emi electro-magnetic interference esd electro-static discharge hc host controller hcca host controller communication area hcd host controller driver ohci open host controller interface pci peripheral component interconnect pci-sig pci-special interest group pll phase-locked loop pmc power management capabilities pme power management event pmcsr power management control/status por power-on reset stb set-top box usb universal serial bus vid vendor id
