THROUGH-HOLE SOLDERING INFORMATION
These devices are intended for wave soldering or manual soldering.
They are not intended to be subject to surface mount processes
under any circumstances.
The normal wave soldering process can be used with these devices
where the device is subjected to a maximum wave temperature of
260°C for a period of no more than 10 seconds. Within this time and
temperature range, internal temperatures within the converter will not
exceed 175°C. Care should be taken to control manual soldering limits
identical to that of wave soldering.
