Does anyone have experience in doing dye and pry analysis on PoPs? A customer wants to know whether or not the board level or device-device interconnect is the suspect. What other technique can anyone recommend? BWET

C-SAM is a non-destructive alternative that a lot laboratories and chip manufacturers use. Dye and Pry would work I suppose although I have never done it in practice with PoP but it should be any different for PoP.

In my opinion destructive methods went out with the stone age. At least they did at our company. We specialize in non-destructive defect analysis. We can determine where the failure is i.e. assembly process, fab defect, BGA defect or plating proce

This is where I purchase nozzles for our Jukis. You don't have to purchase the entire nozzle assembly, just the tip and slider... http://www.nozzlesupply.com/juki.htm I don't have any affiliation with this company, just a happy customer.

Looking for a few good seminars here on the east coast (NY, NJ, PA, etc) on the topic of BGA's, BGA Repair and Rework, etc. Any suggestions ?? Thanks.
