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 PCB's 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.

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
