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.

Subject: [TN] input on pressing cPCI connectors


We have recently designed a 6U board that has the J1 & J2 compact PCI
connectors on it.  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?

TIA
