Manish, I've seen similar phenomenon when processing CSPs on our cards. In our case, we were placing the components over the opening to in-pad blind vias. Due to poor drilling and plating processes by our board suppliers, volatiles were outgassing

How is CPk determined by glass slugs and plates? Can someone explain the process, please? If it's feasible, I'm willing to try it out, also. Thanks, Joe

Has anyone know of a low viscosity conductive paste/liquid that has good thermal conductivity? My aim is to get better consistency in the electrical and thermal conductivity between the mounting flange of Microwave power devices and anodised carrier

Does anyone have any experience they are willing to share on Ag epoxy used as a copper through hole plating replacement? Was CEM3 used? What are the limitations? Thanks, Steve

| Question: | If a PCB and the lands of a part both had electroless plating, would there be a higher tendancy for intermetallics to form in and on the solderjoint...versus just the PCB or Just the part being plated? | I'm currently running into this

Has anyone had experience with placing BGA on gold plated boards. I thought I read a while ago there was a problem with embrittlment causing cracked joints. If anyone has experience with this your feedback would be great. Mike

I am currently using some pick & place equipment and would like to measure their cpk using a glass plate and glass "components" with vernier scales. I have seen these kits but am trying to track a supplier down in UK/Europe. Any help is much apprecia

Does anyone have any experience with fired-silver/platinum/palladium lead terminations soldering. I have had issues on nickel over gold plated boards but not with HASL'd boards with tin/lead pads. Is this the norm?
