Heavy Copper Design Guidelines

Designing 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 while soldering components to the board, which is detrimental to proper soldering. Read these suggested design guidelines for heavy copper boards.
