| What is cause and effect relationship for the Common defects in PCB manufacturing Can you be more specific? Do you mean PCB fab defects as they relate to assembly defects - or? Plus, there are so many cause and effect relationships it would take a

Try Diagnosys.com They run a quick turnaround, low cost service in the UK. CR Technology may do the same in the US. Both have Hi Quality Software for results interpretation. Also worth considering Hirox BGA Inspection systems at Diagnosys.com

Chris thanks for saying nice things about Diagnosys AOI systems.There is also another way of looking for Manufacturing Defects for about the same price - �30K/40K. Single Point Flying Probe using Impedence Analysis techniques is really taking off her

I agree with all the previous comments. You need an XRay system with good software capabilities to "clean up" the images, but you also need to interperate the results and training/experience comes into this. Get free trials first on a machine like CR

Thanks for the input guys. One problem with this theory, we see the same failure using Omni 5000 solder paste. We also see this problem across 4 production lines, suggesting it is not oven related. The profile meets recomendations and we have tried

We determined moisture more as a diagnosis based on omission. We eliminated the other variables, noted that the parts were cracking in reflow, and deducted that it was trapped moisture. As the moisture expands, the component can be cracked/destroye
