(pulse-heated soldering is not recommended for so packages.) for pulse-heated solder tool (resistance) soldering of vso packages, solder is applied to the substrate by dipping or by an extra thick tin/lead plating before package placement. 17.2 plastic dual in-line packages 17.2.1 b y dip or wave the maximum permissible temperature of the solder is 260 c; this temperature must not be in contact with the joint for more than 5 s. the total contact time of successive solder waves must not exceed 5 s. the device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. 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. 17.2.2 r epairing soldered joints apply a low voltage soldering iron below the seating plane (or not more than 2 mm above it). if its temperature is below 300 c, it must not be in contact for more than 10 s; if between 300 and 400 c, for not more than 5 s.
