Good afternoon, Take my word, bent THT leads will surely cause problems with manual/automatic component insertion, and surely will create voids in solder joints. As a rule, PIH components are placed by hand and good PIH THT manual component placemen

Solder Ball After Reflow Process

Hi Umar, I believe you either are over printing these pads or the alignment of board and stencil may be off. Check your print right after your screen printer to verify either. If you are not over printing and your paste alignment is spot on, then

Any help/suggestion is much appreciated I am doing lots of BGA Reworks from a small uBGA with a few balls to a large BGA with over 1500 balls. The reworks have been done on SRT 1100 Series Machine for many years. SRT 1100 Machine is good for the c

Advice Needed between a DEK 265GSX and a MPM UP3030!

Electronics Forum | Mon Oct 09 14:30:44 EDT 2006 | Brian
