Hello Technetters: Processing a 16"x20", .125" thick double-side mixed-tech (smt both sides, and pth component side) with at least two .8mm BGAs with .45mm balls: one is a 84 pin package is a 9 x 15 - 135 - ball matrix with 51 depopulated balls in the center of the package the other is a 8 x 12 - 96 ball - matrix with 8 depopulated balls - 4 at either end of the matrix Two quick questions: Can I clean (in-line) using di water only if I use OA flux? Or, do I need to switch to no-clean for BGAs less than 1mm? For rework, flux only? Or can I micro-stencil or dispense? As always, thanks in advance for your replies, Al Kreplick Sr. Mfg. Eng.
