Dear Smtnettter: Has anyone purchased yellow visible colored dye penetrant for dye and pry testing? Can someone recommend a vendor? BTW this was recommend to me by an end user in japan as some copper problems are "hidden" by the typical red visible

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

HI, I'm doing a dye penetrant and peel test of non-function BGA solder joints to locate the fracture surface. After applying dye, I found the dye ink just accumulate at the solder mask edge and spread everywhere after I peeled off the package. THis i

Dave, we're about to publish a paper in Advanced Packaging mag. on the use of dye penetrant testing. Educate me on how to enclose the paper on this web site and I'll be glad to let everyone review it.

We form a barrier to contain the dye, but regardless it is messy. Actually, we no longer use dye, per say. We use the stuff machinists use for staining metal. Look here for hints: * http://www.ivf.se/Elektronik/dye_penetrant/edefault.htm * http:

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

We are unfamiliar with yellow penetrant. Red is common, as you say. There are couple of green penetrants out there. Some red penetrants contain yeasts [eg, Calcofluor Yellow, Azosol Brilliant Yellow 6GF, etc] that fluorese yellow, but that's not what
