Hi Technetters, I have a not so little problem: I am finding no flow through on TPH holes after the boards are being put through the flow solder machine. It looks like there are 4 to 5 holes per board that have not wetted. This gives us between 3000 and 4000 ppm faults on this problem alone. Those are the symptomes, but what are their implications? Is it one problem? What can I do to solve it?
