Hi everyone,
Do you have any experience with PWB assemblies with BGAs on both sides of the board? What about BGAs that are back to back? Do I need to use any type of SMT adhesive to hold in place BGAs during second side reflow? or the molten solder's surface tension is enough to hold the BGAs on the back side during reflow?
Thanks in advance
