Heavy Copper PCB

Eline23 Feb, 2021News

Heavy copper printed circuit boards are in high demand and are widely used in various electronic industries. The PCBs have become one of the hottest PCBs with a good development prospect in the PCB industry. What is Heavy Copper PCB? Heavy copper PCB has another name, thick copper PCB, containing more than 3 ounces (oz) of copper on the inner or out layers of printed circuit boards. The circuit board with a copper thickness from 4 oz/ft2 to 20 oz/ft2 is also considered heavy copper PCB, while copper weights above 20 oz/ft2 and up to 200 oz/ft2 are referred to as extreme copper. With an appropriate substrate and thicker plating in the through-hole circuit, the copper weight makes these PCBs a reliable wiring platform. These boards are manufactured through a variety of etching and plating techniques. The goal is always to add copper thickness via plated holes and sidewalls.
