Heavy Copper PCBs ( Power PCBs)<br />
Thick copper PCB products are used extensively in power electronic devices and<br />
power supply systems. A growing trend in the PCB industry, this unique type of<br />
heavy copper PCB features a finished copper weight of more than 4oz (140μm),<br />
compared to the 1oz (35μm) or 2oz (0μm) copper weight generally found in<br />
those with a standard PCB copper thickness, you can even get 20oz copper, but<br />
limitations apply.<br />
The additional copper PCB thickness enables the board to conduct a higher<br />
current, achieve good thermal distribution and implement complex switches in<br />
a limited space. Other advantages include increased mechanical strength at<br />
connector sites, the ability to create a smaller product size by incorporating<br />
multiple weights on the same layer of circuitry and the ability to use exotic<br />
materials to their maximum capacity with minimal risk of circuit failure.<br />
