2, Product reason:
In the circuit board industry, the circuit boards with a thickness of 105 um or more are usually called thick copper boards. At present, the thick copper foils mainly used for printed circuit boards are 3 ounces, 4 ounces, 5 ounces, 6 ounces, and sometimes even 16 ounces. The above are 6 ounces Heavy copper pcbs.
Then why use thick copper? Here, we will explain that PCBA is bound to generate heat during its long-term use, which comes from the heating of electronic components, PCB itself and the external environment. Among the three heat sources, the heat of electronic components is the largest, followed by the heat of the circuit board itself. The heating of components is determined by their power consumption. The circuit board carrying high-power components is accompanied by large current. Therefore, when designing a large current circuit board, the conductive layer must be made through large current and circuit board, and then the circuit board's ability to safely withstand the heat generated by large current must be considered.

3, Areas involved:
According to the size of the current that the copper conductor bears, it is proportional to the size of the cross-sectional area of the line. Therefore, the design of increasing the thickness of copper foil or increasing the line width can be used to meet the requirements of high current load. For some power boards with large current and power, more circuits need to be designed in limited space, so the demand for thick copper plates is increasing. At present, thick copper circuit boards are mainly used as high-power or high-voltage substrates. They are mostly used in automotive electronics, communication equipment, aerospace, network energy, planar transformers, power converters, power modules, etc., involving automotive, communications, aerospace, power, new energy, semiconductor lighting, electric locomotives and other fields. This 6 ounce Heavy copper pcb is used in the power converter.

4, Company introduction:
