Power supply circuit board

Thick copper power supply circuit board is a special type of circuit board, which is characterized by the use of thicker copper as a conductive material. This type of circuit board is usually used in high current and high voltage application, such as power conversion, power transmission, etc. Below we will introduce in detail the definition, advantages, production process and application of thick copper power supply pcb board.

What is the definition of thick copper power circuit board？

Thick copper power circuit board refers to the circuit board using thicker copper as a conductive material. Usually, the thickness of copper foil above 1.2mm is called thick copper, and the thickness of thick copper power circuit board often exceeds this value.

What are the advantages of thick copper power board？

Thick copper power circuit board due to its special material and structure, has the following advantages:

1. Strong current carrying capacity: Thick copper power circuit board because the copper is thicker, it can carry more current, so it is suitable for high current application scenarios.

2. Good high temperature resistance: Because the copper is thicker and can withstand higher temperatures, the thick copper power supply circuit board has better high temperature resistance.

3. Good stability: The material and structure of the thick copper power circuit board make it have better stability and can work stably under harsh environmental conditions.

4. High reliability: The material and structure of the thick copper power circuit board make it have higher reliability and can ensure long-term stable operation.

Production process of thick copper power circuit board

The production process of thick copper power circuit board mainly includes the following steps：

1. Substrate selection: Select an appropriate substrate based on the application, such as FR4 and CEM-1。

2. Copper processing: the copper foil is processed according to the design requirements, including cutting, drilling, etc。

3. Circuit production: Circuit graphics are made on the substrate, which can be etched, laser cutting and other ways.

4. Welding process: The electronic components are welded to the circuit board, which can be welded manually or automatically.

5. Inspection and testing: The circuit board is inspected and tested to ensure that it meets the design of requirements.

Thick copper power circuit board application

Because of its strong current carrying capacity, good high temperature resistance, high stability and high reliability ,thick copper pcb power board is widely used in various high current and high voltage application, such as power conversion, power transmission and so on. For example, in the field of power conversion, thick copper power pcb board can be used to make switching power supplies, adapters, etc. In the field of power transmission, thick copper power supply circuit boards can be used to make power transmission circuits, distribution cabinets, etc.

The main application areas of the high-current substrate are two major areas: power modules and automotive electronic components. Its main terminal electronic product areas, some 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 automotive, industrial control, power modules, etc.
