gersla: You're correct that carriers of low temperature material will disfigure and become useless at 125*C bake temperatures. The reason you can not find 70*C bake data is: J-STD033B, "4.2.2 Low Temperature Carriers. SMD packages shipped in low tem

I would sugest the lowere the baking temperature the better, the main cause of popcorning is the water expansion and this is greatest as the water boils, 100 degrees, better to elongate the time. Matt

Table 4-1 only specs the humidity requirement for bake temperatures below 100C. It is conspicuously absent above that. I believe it is because moisture is in its gaseous state above 100C.

Ooooo, much better. Tough to say, because of all the variables [ie, different materials, moisture level, temperature, etc]. Plastic encapsulated devices, especially IC, absorb water from the air, which is violently released during soldering. Typica
