"Thanks for all your informative replies. I do know that Motorola is using a No Clean Eutectic Solder for their BGA's. We are in Aerospace and is using a Water Soluble Paste Flux." This statement is confusing me (not to difficult at my time of life)

Hi DaveF, To explain. The BGA that we have is from Motorola. The solder balls of these BGA's are Eutectic Solder and processed using a NC flux (as per info from supplier). So this means that the BGA pad and solder connections had NC flux process. W

Sure, it�s fine to use the proper amount of flux and no solder when reworking BGA. Recognize that these new solder connections have less metal and a lower standoff than similar BGA solder connections that have not been reworked. This undoubtedly
