solder ball after reflow owen Hi Any, This is from an earlies thread "Solder Ball After Reflow Process". Date: August 16, 2006 01:52 PM Author: Russ Subject: Solder Ball After Reflow Process Oven settings are meaningless here. What does the board see? It is the paste we are concerned about not what the heaters are running at hehe. These solder balls are at the end of pad, which end? under the part or away from the part. I believe you may have stencil issue myself, if profile is good. common ...

Traceability will hard job any way. Not so easy any way because not all the E countries are using same procedures regarding part on stock, not sold by 1-7-2006. Best Regards.....GS
