I hope you are not trying to melt the Ceramic BGA columns. these are not meant to melt. I would run a lead process at peak temp of 225 -230C with lead paste. The board warpage may be of design issue or Manufacture issue. Russ

I've got a question: Can a joint look good externally, even under 45X magnification, and not be mechanically and/or electrically sound? I thought that if the wetting angles were sufficient, there's no discoloration from extreme thermal distress, or

Let me make several points on this issue � POINT 1: Let�s be basic � Soldering and welding are examples of process that the quality types call "special processes". Special process. The results of special processes cannot be verified fully by subs
