As the demand for high-power products continues to rise, so does the need for heavy copper or thick copper PCBs. At Stream PCB, we manufacture standard PCBs with a copper thickness of 1-3 oz (35-105 µm) and also produce thick copper PCBs with a finished copper weight exceeding 4 oz, reaching a thickness of 140 µm.
For all your thick copper PCB needs, trust Stream PCB—the leading manufacturer in the industry.
Our heavy copper PCBs are widely used in power electronic equipment, such as power supplies. The added copper weight enables higher current conduction while minimizing temperature rise. While most of our thick copper PCBs are single- or double-sided, we also manufacture multilayer versions.

Manufacturers of high-power electronic products rely on heavy copper PCBs to address thermal efficiency challenges. These PCBs are primarily used in automotive electronics and power modules. Instead of using cables and metal sheets for power distribution, these manufacturers depend on high-quality heavy copper PCBs from Stream PCB.
Using heavy copper boards not only enhances productivity but also reduces costly wiring, leading to improved product reliability. Eliminating wiring also contributes to product miniaturization.
For applications that demand high cooling, high current, and high power, heavy copper PCBs play a crucial role. These PCBs are more expensive than standard boards due to the additional copper, the need for advanced equipment, and the expertise required for their manufacturing.

For us, every heavy copper PCB is a special PCB. We use specialized conductive materials, substrate materials, and unique production processes that differ from those used for conventional boards. To enhance copper weight in the sidewalls of vias and plated through holes, we utilize thick copper plating. This approach helps reduce the number of layers while allowing for the integration of high-current and control circuits, enabling high-density boards with simplified structures.
In the regular subtractive manufacturing process, etching heavy copper PCBs presents the challenge of undercutting, which results in copper traces having a trapezoidal cross-section rather than a rectangular one. To overcome this issue, Stream PCB employs an additive manufacturing technique, where we build up the heavy copper using a plating process.
