The thick copper circuit structure gives the circuit board the following advantages:
Firstly, it can improve the ability of the circuit board to withstand the thermal strain.
Secondly, it can increase circuit performance and current carrying capacity, at the same time improve the welding mechanical strength between the components and PTH holes, and reduce product size. furthermore, the vias of the heavy copper PCB usually carry a large current on the board, so this is going to help to transfer heat to the external heat sink.

The application and demands of heavy copper circuit board have been rapidly expanded in recent years, it has now become a quite popular PCB product. for example, electric-powered vehicles.

Heavy copper PCBs usually carry out large current in high power electronics. There are two major areas, power modules (power modules) and automotive electronic components. Its main terminal electronic product fields are the same as conventional PCB (such as portable electronic products, network products, base station equipment, etc.), and some are different from conventional PCB fields, such as automobiles, industrial control, power modules products, etc.

Up to 6oz products

The heavy copper circuit board usually is thicker than 2oz, however, Fuxiang can offer PCB up to 6oz, most of the heavy copper products are around 3oz and 4oz though, the min hole size of the circuit board is subject to the total thickness of the board.

Longer delivery

It is no doubt that the delivery of this kind of PCB is longer than the normal FR4 PCB, usually, it is 6-10 days. which depends on the different project designs.
