Any member in here has experienced of copper migration from BGA's substrate to PWB during eutectic soldering reflow process, which resulted in brittle solder joints??? We have one customer notified us that our PBGA with DSOP substrate having copper m

The problem is registration between the stencil & the smallest pads on the 5 substrates. Using SPI s/w I can overlay the paste layer over the PCB image to determine stretch/shrink. Our worst case was shrinkage of 10.2mil on a 5-up 300mm panel - small
