Frequently Asked Questions about Thick Copper Circuit Boards
1.What advantages does the construction of a thick copper circuit confer on a circuit board?
Increase resistance to thermal strain; increase current carrying capacity; increase mechanical strength of connector sites and PTH holes; take advantage of special materials (i.e. high temperatures) without circuit failure.
2.What is a heavy copper PCB?
Heavy copper PCBs use 4 or more ounces of copper per layer.
