Thanks for all the info Dave. It's the interconnect between the copper foil pad and the eutectic solder ball that I'm most interested in. The BGA in question is very thin gold plated over nickel over the copper. When we are reworking the BGA, i

A really nifty nest can be made by making an RTV mold of the first side of your assembly. Assuming all are identical within some small tolerance, the resulting mold holds the board very securely and distributes the loading. Cover the components with

Are these blades coated with something like PTFE (teflon)? If so does the coating flake off over time. Incidently I just got a pice quote and they are 4.5X that of our standard MPM nickel plated spring steel, so I wanted to make sure they would last

Larry: Cookson spun Alpha's instruments (omegameters and such) into its specialty coatings group, you know with Paraline and all that. Makes sense to me. Of course, I don't connect with the whole Cookson approach anyhow, but they have money and th

Assuming that you are going to solder them into a board rather than socket them, yes. The thickness of the gold plating in this application will usually make up a large enough percentage of the total joint to threaten enbrittlement. Use a small sol

This is our first time out processing material with a finished thickness less than the standard 0.062 FR-4 material. We have an assembly that uses GIL MC5 with a finished thickness of 0.035 and we are having difficulty at placment with the array "bo

Hany, ESD mats, in my opinion, are very important. Why jepordize the quality of your product. We use sheets of stainless steel around all areas that are ESD sensitive and ground them to the machines. Of course they are no good unless the people st

Fuji is usually the cheapest you will find. I think around $750 for them to repair it. the last time I checked they have an exclusive patent on their PCB backplane design so there would not be any real way to bench test it. they also have rights to t
