Hi! I have a Ms. Pac board that has one of the edge connector contacts
peeled back. What is the best (right) way to repair the contact? Thanks!!

I'm sure there are alot of different opinions on this and I've seen
some different approaches.
Bob Roberts wrote up this article, I use this on the few PCB boards
where I've "repaired/replaced" the edge connector.

Bob Roberts idea is a clean easy fix, however when you consider that you
have just doubled the number of connections you might see that this is
going to fail in the future.

It is much simpler to use only 1/2 of his suggestion - the double-edged
card extender strip - butt it up directly to the damaged card edge
connector - and solder to it DIRECTLY with short jumper wires. Take care
not to allow the solder to get far enough onto the strips so the solder
will interfere with the cabinet edge connector and you are then good to
go. New card edge connector, and no extra connections to fail. If you do
the job neatly it looks like you have simply extended the original board
card edge connector the length of the small double-ended card.

Of course you MUST also replace the cabinet card edge connector plug at
the same time, as the contacts in it have failed.

We've done this repair over the years and it works very well.

Hi John, I'm trying to imagine what your suggesting, but I don't think
I"m reading it right.
do you have a picture of one of your repairs that you could post so we
can see how your doing it?

I don't see how you can add the edge board without the female
connector to hold it steady.
I'd love to see though as it sounds like you have had alot of sucess
with your method and it it uses less parts, so it's got to be a less
expensive fix.
