Hi Sandy, Here are some suggestions for an optimum cleaning process for cleaning under BGAs if they are assembled to the board to add to the great tips Shean already listed: - Use a good saponifier w/ DI water - an effective saponifier will be able

Thanks all. We are using no clean, so the boards are not washed. That would eliminate the trapped water issue. We would check the PCB after dismounting the BGA, and the short would not be found. When we place another BGA on the board, the board w

Hi Sandy B, You certainly can clean the BGA's using an inline or batch process. The correct method to hold them during this process, is the method that provides the desired outcome. I'm familiar with the desired outcome for cleaning singulated BGA

LOOKING FOR THE PROS AND CONS OF BOTH WATER SOLUBLE AND NO CLEAN PROCESS MATERIALS AS IT APPLIES TO BGA REFLOW.IS IT POSSIBLE TO REMOVE ALL W/S FLUX AFTER INLINE WASHING. THANKS MRMAINT

I am looking for a method (Automated preferably) to clean any residue and or debris from a BGA after rework. Is it possible to clean them using an inline wash process, as long as the devices are intact and held correctly. What woudl be the correct m

Washing no-clean solder residue out from under BGA's might present a challenge.

Does anyone have experience doing conformal coating over Plastic BGA in High-Rel PCB assembly? Is underfill necessary to avoid problems with entrapped air, etc? Our application is a 17x17mm BGA, 256 I/O. We are assembling with a water soluable pas

One more thing to think about - if placing BGA's using water sol., you must ensure they are clean and dry beneath the component post wash. A few ways to do this. Simplest is to use DI from low pressurized nozzle and hand wash them at different atta

Hi Dreamsniper, It seen this is the major issue had been occurs you.( We had face all this issue last time too) We had done a lot of areospace products before and most of ours products is a must on class 3 spec. BGA is not that tough t

Larry, Yes, no matter how much you�d like to avoid using NC, you probably will have to start using the stuff, if the design [sales, in your case] types have their way. We can clean WS under 1mm and 1.25mm pitch BGA. For 0.8mm pitch BGA, we use NC.
