Dear Steven: Often the recommendations for baking prior to assembly are derived from various J-stds. But J's currently concern baking moisture out of components, and fail to address the moisture issues of the PCB. Because of that, there is the IPC D

Interesting suggestions so far - keep 'em coming as I do a search on every one of them. Speaking of, it seems that if the humongous size of the older MyData machines isn't an obstacle then they seem to be a good choice for us... (to recap: we need t
