A tool for holding a pin header to a PCB to aid when soldering. Will hold the pcb and header steady while at the same time making sure that the header is soldered with a correct angle. 

To use it clamp the board and header. Start by soldering the pin that is in the center of the clamp . Move the clamp to solder the rest of the pins.

I wanted to avoid strange extra hardware so the only thing needed is a >14mm long M4 screw and a rubber band.
