What Are The Latest Advances in PCB Technology?

EXTREME Heavy Copper

UPE defines EXTREME Heavy Copper PCB's as any board design containing tracks or features greater than 20 oz/ft2. Our latest process innovations afford us the ability to offer copper features up to 200 oz/ft2. That's 0.280" thick tracks with the capability to carry more than 1,000 amps continuous. This is a quantum leap in technology from what is known as Heavy Copper PCB's. Excitement among designers has been off the chart.

Introduction to Heavy Copper and EXTREME Heavy Copper.

Heavy Copper

UPE defines Heavy Copper PCB's as any board design containing tracks or features greater than 4 oz/ft2 and up to 20 oz/ft2. Heavy Copper PCB's allow design engineers the ability to scale up existing designs to higher power levels while keeping the power components on the PCB.

Introduction to Heavy Copper and EXTREME Heavy Copper.

Power Link

PowerLink is a term UPE uses to describe the use of 2 or more copper weights on the same layer of a printed circuit board. The Heavy Copper and standard copper features can be interconnected. This allows for fine pitch devices, using standard copper traces, to be mounted on the same board with power devices demanding the use of Heavy Copper tracks.


From standard 1 oz/ft2 Cu to EXTREME Heavy Copper at 200 oz/ft2. UPE continues to bring new innovations to the world of printed circuit boards.

UPE was the first to...
  • Make 10 oz. copper PCB's available
  • Make Powerlink available
  • Make 40 oz. copper PCB's available
  • Offer EXTREME Heavy Copper boards up to 200 oz/ft2.
