Kathy- Greater than 88%. Is that 3-D Nicolet? I had a conversation with Arline yesterday, she told me about your trials and tribulations with re-balling. I would like to suggest you try micro-stencil instead. If your BGA rework center has the capabi

Janet, There's 25-minute IPC VT-91 video on Introduction to Surface Mount Rework (if available in your office) you can start with. To keep you going, you can request the dummy component catalogs from Practical Components and Topline Dummy. 'Think, th

Bait, my ass. Something so thinly vailed is what I'm talking about on this forum. However, Janet is a prime example of someone needing help and you folks kindly offered with good advice. How could you not give good advice to someone needing everythin
