EXTREME Copper PCB Capabilities Webinar

An increasing number of power electronics products are taking advantage of a growing trend in the printed circuit board industry: Heavy Copper and EXTREME Copper Printed Circuit Boards.

Most commercially available PCBs are manufactured for low-voltage or low power applications, with copper traces or planes made up of copper weights ranging from 0.5 oz/ft2 to 3 oz/ft2. Heavy copper PCBs can have more than five times that copper weight, and EXTREME copper PCBs can range up to 200 oz/ft2.

In this webinar We will discuss design considerations unique to this product as well as how much current these boards can carry. The minimum conductor width and spacing and cost trade-offs for the different techniques will also be covered.

Areas Covered in this Webinar:

EXTREME Copper PCB Capabilities
  • Increased endurance to thermal strains.
  • Increased current carrying capacity.
  • Increased mechanical strength at connector sites and in PTH holes.
  • Use of exotic materials to their full potential (i.e., high temperature) without circuit failure.
  • Reduced product size by incorporating multiple copper weights on the same layer of circuitry.
  • Heavy copper plated vias carry higher current through the board and help to transfer heat to an external heatsink.
  • On-board heatsinks directly plated onto the board surface using up to 120-oz copper planes.
  • On-board high-power-density planar transformers.
