Heavy Copper Printed Circuit Boards

Heavy Copper PCBs, also known as thick copper PCBs, are a type of printed circuit board with a copper weight of more than 3 oz per square foot. This makes them highly suitable for high power applications, as the thick copper layers can handle higher currents without overheating.

At YScircuit, we specialize in manufacturing Heavy Copper PCBs with copper thickness ranging from 4 oz to 50 oz. Our state-of-the-art facilities and experienced team ensure that we produce high-quality Heavy Copper PCBs that meet the most stringent industry standards.

Our Heavy Copper PCBs are ideal for use in a wide range of applications, including power supplies, motor control, automotive electronics, and more. With their exceptional thermal conductivity, they help dissipate heat efficiently, improving the overall performance and reliability of the system.

In addition to our standard Heavy Copper PCBs, we also offer customized solutions tailored to meet your specific requirements. Our team of engineers and designers work closely with you to develop Heavy Copper PCBs that meet your exact specifications.

At YScircuit, we are committed to providing our customers with the highest quality Heavy Copper PCBs at competitive prices. Contact us today to learn more about our products and services.

The construction of heavy-copper circuits gives the PCBs the following advantages:
1.Increase current capacity greatly
2.Higher endurance to thermal strains
3.Better heat dissipation
4.Increase the mechanical strength at connectors and PTH holes
5.Reduce the product size

Along with the increasing of high-power products, the demand for thick-copper PCBs is greatly increased.

Today’s PCB manufacturers pay more attention to using a thick copper board to solve the thermal efficiency of high-power electronics.
The thick-copper PCBs are mostly large current substrate, and large current PCBs are mainly used in power module and automotive electronic parts.

Traditional automotive, power supply, and power electronics applications use the original forms of transmission like cable distribution and metal sheet.

Now the thick-copper boards replace the transmission form, which not only can improve productivity and reduce the time cost of wiring, but also increase the reliability of final products.

At the same time, the massive current boards can improve the design freedom of wiring, thus realizing the miniaturization of the whole product.

Thick-copper circuit PCB play an irreplaceable role in the applications with high-power, high current, and high cooling demand.

The manufacturing process and materials of heavy-copper PCBS have much higher requirements than standard PCBs.

With advanced equipment and professional engineers, YScircuit provides thick-copper PCBs with high-quality for customers from home and abroad.
