I recently had some shields made and a problem I have with them is that their male header pins bend when I separate the shield from the Arduino. They are too soft. Any suggestions on what material the header pins should be made of so that they do not bend so easily? Brass/Bronze/Titanium etc.
As somebody mentioned already… it’s usually necessary to slowly separate the shield from the arduino … such as to apply a tiny bit of separation on one end to begin with…then work on the other side (to get some separation, but not full separation). And keep repeating these steps in stages. Eventually, the shield and arduino can be separated without pins getting bent.
What you’re probably doing right now is using force to just rip the two sides apart. That will certainly bend pins. Here, I’m talking about UNO pins.
I know that shields for larger boards with lots of pins… like Arduino MEGA can be a real pain to couple together, due to pin misalignment. Separating is no problem though.
