Mark, This topic has been discussed multiple time on this site. You can find almost all of them by searching the archives for tombstoning. That aside, have you look at your stencil apetures?(homeplate design).

Are there any other manual reballing systems aside from the one made by Hepco that use a vacuum method for ball placement?

Aside from process flows where the next step is: 1 Powering-up an assembly 2 Testing the assembly on electronic test equipment Is there a reason (need) to dry assemblies after water washing followed by a DI water rinse? Or is air drying OK? Dave F

Yannick, If we leave the 201 issue aside; have you checked where those BGA pads are connected to? Could those be power/ground balls connected to large (difficult to heat up) planes by any chance? Erhan

IMHO, this finish is more cosmetically appealing than technically desirable (and VERY profitable for the PCB maker). That editorial comment aside, you're correct. Increasing the concentration of gold: * Hardens the solder. * Increases the liquidou

If you are facing the back of the machine take left most panel off. There are usually two fans built into this panel.(unplug the fan connector and set cover aside) The servo-driver cards will all be in a row. They should be labeled accordingly.

Aside from a visual first article to IPC 610, what inspection criteria do people put in place post wave solder (pre clean)? Thank you
