Many shields come with square pins. Recently I de-soldered a couple of them. For most shields this worked fine. After the pins were gone I had clean holes with good contact to the traces.
But with two SD-Card shields I ruined the holes and the connection to the traces. On one of them only one trace connection was gone and I fixed it with a little wire. On the other module several traces are ruined and probably I won't spend the time trying to fix it soldering to micro SMD parts.
My question is: Should these holes easily survive soldering and de-soldering a couple of times? Are there big quality differences between the PCBs? Or did I likely do a bad de-soldering job and that ruined them?
Normally my soldering skills are relative good and I have a temperature controlled Hakko soldering iron. But I do a lot more soldering than de-soldering, so maybe I just have to learn this.
What is your experience especially with removing square pins with lots of contacts from shields?
