First, what on the area array package are you analyzing � * Package cracking? * Cracked solder balls? * Er, what? Second, most failure analysis discussions consider dye penetration to be a non-destructive test, but then again most failure analysis

Put on your Chemical Thinking Caps..... We are ablating the mask of a PCB which was over a copper layer. This exposes copper. Outside of an electrical test (no can do) how could we use a fast non-destructive test in order to determine that copper (

I read a paper somewhere that outlines a non destructive test for black pad detection. it showuld be on my hard drive. Black pad is as a result of impurities in the plating bath and poor process control. I shall dig up the paper and mail it to you if

I don't believe I have ever seen a non-destructive test for "Black Pad" that I could take back to a Fab house and collect monetary losses with... But if this test method actually does hold merit then collect away. I would like to know how this metho

Please inspect the pcb were the components were "lost" Check if the glue dots were lef on the PCB.If so you have a component which has been contaminated.If the dots dont appear on the PCB,which is the more common of the 2,there is an adhesion problem

Amazing in today's technology that people still bake because "that's the way we've alawys done it". Baking is a band aid for poor manufacturing of the PCB. Moisture can become trapped between the layers during buildup. This moisture when it contacts

| It seems like most people want to X-Ray their BGAs. We're going to start doing a lot more of them and need to consider X-ray, too. | Q: Do most people/companies X-ray everyBGA or do they just do SPC? | Q: Can you get away with spending 25K? 30K? H
