While it does not hurt the CCA to solder in pressfit pin connectors, you will not be able to rework (remove) them later. Soldering of connectors with pressfit pins is a very permanent proposition. Removal can be done, but it is very, very difficult.
The process for pressfit connector removal is to gang-press the pins back through the board. If they are soldered in place, your only recourse may be to cut off the connector body and pull the pins out one pin at a time while the solder is in liquidus. You can't press them out because the tooling will cause the leads to heatsink, making it almost impossible to desolder.

All:

    I have a customer who is specifying a press fit connector to be soldered after the press fit operation. I've never heard of this and I was wondering if there is any quality/reliability data in the industry as to why one should/shouldn't do this. Our customer's explanation was that it would add mechanical integrity to the joints. Thanks in advance.

Regards,
Steve Vargas
