An increasing number of power electronics products are taking advantage of a growing trend in the printed circuit board industry.
PCBs with 3oz or more of finished copper in the inner and/or outer layers are defined as Heavy Copper. Our manufacturing facilities allow Heavy Copper boards to be produced up to 32 layers.
We also have the capability for Extreme Heavy Copper - up to 30oz per layer for 2 layer applications.
Heavy Copper and Extreme Heavy Copper PCB's offer benefits such as:
DK-Daleba can help you with design procedures for Heavy Copper. We can offer track and gap spacing guidance, current-carrying details and best practice guidelines for heavy copper circuits.
