philips semiconductors product speci?cation 2 24 w btl or 4 12 w single-ended car radio power ampli?er TDA8561q soldering introduction to soldering through-hole mount packages this text gives a brief insight to wave, dip and manual soldering. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). wave soldering is the preferred method for mounting of through-hole mount ic packages on a printed-circuit board. soldering 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. manual 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 up to 5 seconds. suitability of through-hole mount ic packages for dipping and wave soldering methods note 1. for sdip packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. definitions life support applications these products are not designed for use in life support appliances, devices, or systems where
