Need some opinions from you fine folks. We are building assemblies 90% SMT, 10% TH. Fine pitch and BGA devices, etc. The customer is complaining about cold solder joints (SMT) after about 1 year of use, scattered thru-out the assembly, not consistan

Drill a hole through the board (or the BGA) and set a thermocouple into the center of the device (in the X Y and Z dimensions) and run your profiler through the oven until you get the temp you need in the center of the BGA. Attach a second thermocoup
