Hi, Thanks for your reply. I run 2 boards, using the same paste, thermal profile and the same method of aqueous cleaning, 1st is a Topline test board with topline BGA (BGA 272 with 1.27 Pitch) and the 2nd is our product PCB with our BGA from Motoro

Customer returned a brd claim that one of the FPGA is having "cold solder joint". I inspected the the BGA location with X-ray and Ersascope, balls' shape look fine, voids are not detected, perimeter joints show shinny and smooth appearance, i have se
