Hello, I am looking for information on the Dye Penetration test for area array package failure analysis. Any recommendation on the dye to use? Any articles leading to this? Any comments on the effectiveness of this test? Regards, Arul

Thanks David.I do not have any specific failure analysis to do now. But, like to use this technique in future. Appreciate your composure even during this time of unprecedented attacks. Regards, Arul

Just because I�m not currently ranting about nuking Kabul, Tehran, Baghdad, and Algiers or laying a coat of jellied gasoline on those little punks celebrating with their candy in Palistine; that doesn�t mean my shock and grief will not turn to anger.

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

A man in a hot air balloon realized he was lost. He reduced altitude and spotted a woman below. He descended a bit more and shouted, "Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don't know where I am." The wom

I just ran into a reflow profiling problem with a new assembly that we are processing in SMT. There is a cluster of six or so electrolytic caps that measure approx. .710" wide by .660" tall. They are spaced .100" or so apart. When I run a profile, t

I wouldn't raise the temps just slow the conveyor, You need to get the PCB "soaked in". It seems as if you are applying more thermal energy than the PCB can accept in all areas. Does this oven have convection heating? Hopefully so. I have found t

Hi, We have had some failures due to particles, but only larger visible particles such and you should not need a real "clean room" but it's important to make sure things are kept clean, and sweep and mop as often as you need to make sure everything

I understand that there may not be a lot of material on this, as most threads I've seen discourage doing it. It goes against DFM to do it. But I wish to use a large copper area instead of heat sink and thermal epoxy to cool a regulator. But I can'
