Assembling high current heavy copper Printed Circuit Boards (PCBs) can be difficult, as the heavy copper functions like a double-edged sword. While heavy copper serves to remove heat efficiently from the components when the board is operating, it does the same whilesoldering components to the board, which is detrimental to proper soldering. This necessitates supplying extra heat to the junction to facilitate soldering, which may be harmful to the component being soldered.
