Hi Bryan,

I concur with Phil. The holes need to be drilled to spec to begin with,
and have good plating. Amp/Tyco says in their documentation that you
should be able to repair their "Action Pin" compliant press fit
connections once. That means the initial insertion and a repair, and
that's the guideline I always went by. Like Phil, most of the repairs I
did was because of initial insertion problems, one pin folded under, or
a connector off by a row when multiple connectors were pressed in next
to each other.

It's been a little while since I've repaired a connector, but it's just
like Phil says, taking the body apart and pulling it out pin by
pin...fun stuff.

Subject: Re: [TN] Press Fit Connector replacement

I had some experience.....but I have not performed this for about ten
years......

I used to remove and replace press fit connectors when we would have
problems with proper insertion.

It required completely destroying the connector body with cutters and
extracting the compliant pin by pin out of the PWB with a pair of
pliers.

I do not remember damage to the barrel after removal.

The key was having the right amount of copper plating in the barrels.

Subject: [TN] Press Fit Connector replacement

Hi All

Any views or experience of replacing press fit connectors ? I have some
concerns since I would assume there would be some copper thp distortion
during the first fit and this may affect the reliability of the refit ?
Some internet trawling seems to show that the "compliant" design pins,
where there is a slot in the centre, are more compatible with remove and
replace since some of the distortion will be in the pin. It is a
"compliant" type of pin in my case but could do with some assurance that
this would be OK to do.

Any thought / experiences appreciated

Regards
