Dee, On some early designs done by one of our customers, they found similar issues. Laying out the board for FCI wouldn't allow AMP connectors to be pressed in. They ended up using the AMP layout and we haven't had issues since. I believe AMP and ERNI are virtually identical in spec. In our experience, tooling is critical, especially underboard support and even pressure on entire connector. You might check out the AMP site for documents on their tooling and installation. They have quite a bit of information available on this.

I used the manufacturers spec for the hole sizes and the board shop fabricated within the tolerance and specification. The problem is we can not get the connectors to actually press into the holes. I would appreciate input from anyone who has some experience with these connectors! My understanding of the press tool was that it was nothing other than a flat piece of metal in a bench press. Is that correct? What finished hole sizes are being used? With all manufacturers? I have noticed some dimensional differences in the drawings between Erni & FCI/Berg. Can anyone give me an idea of what the press tools actually look like?
