Typically, the copper thickness of a standard PCB is 1oz to 3oz.Thick copper PCB or thick copper PCB is the type of PCB where the finished copper weight exceeds 4oz (140μm).

What is the use of thick copper PCB?

Thick copper PCBs are widely used in power supply systems and power electronics.The extra copper weight in PCBA production allows for higher current conduction from the board and helps with heat dissipation.The most common thick copper PCBs are double-sided or multilayer.

Thick copper PCB belongs to a special type of PCB.Its conductive materials, substrate materials, production processes, and application areas are different from conventional PCBs.Plating of thick copper circuits allowed PCB ManufacturingCommercial increases the weight of copper in the through-hole sidewalls and plated holes, which can reduce the number of layers and the space occupied.The thick copper plating integrates high current and control circuitry, allowing high density to be achieved with a simple board structure.

The construction of thick copper circuits brings the following advantages to the pcb.

1. Substantial increase in current capacity

2. Higher resistance to thermal strain

3. Better heat dissipation

4. Increase the mechanical strength at the connector and PTH hole

5. Reduce the size of the product

Application of thick copper PCB

With the increase in high-power products, the demand for thick copper PCBs has also increased significantly.Today's PCB manufacturers are more focused on using thick copper boards to solve the problem of thermal efficiency of high-power electronics.

Thick copper PCBs are mostly high-current substrates, and high-current PCBs are mainly used for power modules and automotive electronic components.Traditional automotive, power supply and power electronics applications use primitive forms of transmission such as cable distribution and metal plates.The use of thick copper sheets instead of transmission forms now not only improves productivity and reduces the time cost of wiring, but also increases the reliability of the final product.At the same time, high-current boards allow for increased design freedom in wiring, resulting in miniaturization of the entire product.

In short, thick copper circuit PCBs play an irreplaceable role in pcb mass production applicationsWith high power, high current and high cooling requirements.Heavy copper PCB manufacturing processes and materials have higher requirements than standard PCBs.
