High-quality Multilayer Heavy Copper PCB

Heavy copper FR4 PCB can bear large current load, strong heat dissipation capacity, designed for inverters, energy storage power boards and new energy charging control circuits.

Inquiry

Heavy copper printed circuit boards are special PCBs that use ultra-thick copper layers (≥4 oz/140μm, up to 20 oz/700μm or even thicker) to meet the needs of high current & strong heat dissipation & high reliability. And this kind of PCB can offer better solutions for overheating and burnout issues in standard PCBs under high-current conditions. Its most important feature is that the thickness of the copper layer (conductor and copper-plated area) on the circuit board is much thicker than that of a standard PCB. It is mainly used in high-power fields such as new energy, industrial power supplies, and automotive electronics. It is a key technology that breaks through the performance limits of ordinary PCBs. Compared with ordinary PCBs, heavy copper circuit boards are thicker in appearance than ordinary PCBs, and the thickness of the copper layer in the cross-section is 5-20 times that of standard PCBs. Because the heavy copper circuit board has a high proportion of copper, the weight of the entire board is heavier than that of standard PCBs as well.
