Thick Copper PCB

Thick copper PCB products are used extensively in power electronic devices and power supply systems. A growing trend in the PCB industry, this unique type of heavy copper PCB features a finished copper weight of more than 4oz (140μm), compared to the 1oz (35μm) or 2oz (70μm) copper weight generally found in those with a standard PCB copper thickness.

The additional copper PCB thickness enables the board to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space. Other advantages include increased mechanical strength at connector sites, the ability to create a smaller product size by incorporating multiple weights on the same layer of circuitry and the ability to use exotic materials to their maximum capacity with minimal risk of circuit failure.

Finished Copper PCBs of Superior Quality

PCBAndAssembly 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.)
