Heavy Copper PCB

Heavy copper PCB is also known as thick copper PCB, in which there are 3 ounces (oz) of copper or more on the


internal and external layers of a printed circuit board. The circuit board with a copper thickness of more than 4 oz


per square foot (ft2) is also categorized as a heavy copper PCB. Extreme copper means 20 oz per ft2 to 200 oz per ft2.



The reason why heavy copper PCB is the reliable wiring platform is that the thicker plating in the through-holes


circuits and an appropriate substrate combined with copper weight. Heavy copper conductors can improve the


whole PCB thickness considerably, so it needs to take the copper thickness into consideration as PCB design.


The width and thickness of thick copper determine the current-carrying capability.


HCH-PCB is a highly skilled thick copper PCB manufacturer that can develop and produce a superior thick copper


PCB product of the highest quality. We offer a thick copper PCB manufacturing service that uses copper weights


of up to 15oz (525μm). Check our capabilities in the following table:

Finished Copper PCBs of Superior Quality


HCH-PCB has a decade of experience in manufacturing and assembling high-performing standard and heavy copper


PCB products that help our customers achieve their productivity and profitability goals. We make it a standard


operating procedure to have our highly skilled engineers run design for manufacture on every circuit file, and address


all questions and concerns before production. This helps to ensure the finished electronic boards meet your


performance expectations. Our capable staff includes an in-house quality control department – we guarantee the


quality of our printed circuit boards.


(Note: To ensure we can fabricate your thick copper PCB correctly, it is important to take the greater width of traces


and spacing between the traces caused by the increased copper weight into consideration.)
