Thick copper PCB

Thick copper PCB is widely used in power electronic equipment and power supply systems. The growth trend of the PCB industry is that the finished copper weight exceeds 4oz (140μm), while the copper weight of the standard PCB is usually 1oz (35μm) or 2oz (0μm).

The extra copper of PCB allows the printed circuit board to conduct more current and achieve excellent heat distribution, which can realize complicated functions in a limited space. Other advantages include improving the mechanical strength of the connector position, the ability to make the smaller sizes of products by combining multiple weights on the same circuit layer, and the ability to use exotic materials with maximum capacity and minimize the risk of circuit failure.

Advantages of thick copper PCB:

1) Greatly increase the current capacity

2) Higher resistance to thermal strain

3) Better heat dissipation

4) Increase the mechanical strength of the connector and PTH hole

5) Reduce product size

Application of thick copper PCB:

With the increase of high-power products, the demand for thick copper PCBs has also greatly increased. Nowadays, PCB manufacturers pay more attention to the use of copper plates to solve the thermal efficiency problem of high-power electronic equipment.

Thick copper PCBs are mostly high-current substrates. The high-current PCBs are mainly used for power modules and automotive electronic parts. Now, copper PCB has replaced the transmission form, which will not only increase productivity and reduce the time cost of wiring but also improve the reliability of the final product. At the same time, the high current board can increase the design freedom of wiring, thereby achieving the miniaturization of the entire product.
