Countersink Pcb Heavy Copper Pcb Boards For Medical Machines

What is heavy copper PCB?

Heavy copper PCBs have gained significant popularity across diverse electronic sectors due to societal advancements.

These PCBs offer the capability to incorporate complex switches within confined spaces while ensuring efficient heat dissipation and handling high current levels.

The prevalent designs for heavy copper PCBs include multilayer and double-sided layouts, facilitating the integration of intricate layout structures on the outer layers alongside heavy copper layers within the internal ones.

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.
