What is your experience especially with removing square pins with lots of contacts from shields?
I also think it would be unreasonable to expect boards to be built or designed so that they can undergo a few iterations of re-work.
370C most components won't last long there. I get nervous at 240. Most solder will melt just fine at 200
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?
