We too are baking required components at 125 degrees C. One of the problems that is comming up is components packaged in tubes. The tubes cannot stand the 125 degree requirement without melting. 50 degrees is a safe temperature for low temp carriers

Ashok: The real concern about moisture sensitivity is in plastic packaged parts. The plastic packaging used to manufacture surface mount technology devices absorb moisture from the environment. The high temperatures involved in vapor phase/reflow

Charlie B: You mentioned that you have an air conditioned environment and a RH 0rf 50, baking the boards is predominately done when the history of the PCB delivery and / or previous storage conditions are un known. When I was with a CM, we did this a

I have a multi layer (8) PWB with blind vias going from 1 to 7 that is experiencing occasional blistering (delam). It is only on perhaps 15% of the boards run. We vacuum baked (85C, not sure what pressure) a sample lot and still had a few exhibit the

Could anyone please give me some insight on the time/temperature requirements for curing SMT adhesive used for a high temperature (96/4 solder) application in a bake oven, rather than using reflow? I understand that it would probably vary from epoxy

These images are of two melted matrix trays, full of BGA components, which were left to bake in an oven over the weekend. The oven temperature controller was not checked after a recent power failure and reached a temperature of 715�F. The two trays m

We have problems with achiveing a void free soldered joint when we seal different kind of packages (QFP,LCC and PGA) We think the problem partly is due to outgasing from the die-adhesive (silver-glass) Does anybody have any reccomendations what to d
