Is there an industry standard for compatability between multiple testers? For example, if an assembly fails on one tester, but passes on another? I realize that target is 100%, but with analog testers, this is not going to happen. Personally, I

Thanks Steve. I do know that my vacuum and height/pressure are as they should be. You make a good point about the saturation of the paper. I will certainly check that.

OK, part touching paste before reflow? Check part. Maybe bad plating. Check reflow profile by slowing conveyor.

Can u elaborate on the bad plating? Have u had any experience on this before? The component has 90/10 Tin lead plating

Questions are: * So after you spot one of these leads sitting on a nice pillow of solder, what happens? * Do you rework the part? * Does it take solder? * What do you do to make it take solder, if it does take solder?

We had similar problems with some of our products and found the root cause was our ICT fixture. The damaged balls/pads were always in a certain locations so finding the pattern helped. It also didn't help that the boards were ICT'd 10 + times.

Crazy Question, but do you know who the board house is that is making the boards. We also use alot of flash gold and have noticed many problem with one particular board house.
