Surface mount socket savers | 8 October, 1999

I'm searching for a source for surface mount socket savers that accept a hand test socket (Yamaichi, Nepenthe etc...). Barring availibity of an SMT socket saver does anyone know a good technique for soldering socket savers into a .250" thick, 20+ layer board ? Any help would be appreciated.

Convective air preheaters work amazingly well if there is enough CFM (cubic feet of air) emitting from the top. Get your board temp as close to 150-165C as possible. This will allow you to reflow your solder at a lower temp (450-500F) preferably using a convective air tool set at a warm (rather than hot) temperature. This process with effective preheat and paste will create beautiful fillets on the heal and the toe. The whole "sole" of the lead will be soldered as well. Definately more reliable than a common "tack" joint. Especially with those pesky sockets.

Good Luck!
