PCB is manufactured for low-voltage/low power applications. Heavy copper PCB is used for high power distribution boards, heat dissipation, planar transformers and power converters. Since the electricity usage is increasing day by day, therefore, it is efficient to save as much electricity possible. A heavy copper circuit is manufactured using copper weights between 4 oz/ft2 to 20 oz/ft2.
Heavy copper PCB is only going to work effectively when they are designed correctly. This is used in various industries for welding equipment, solar panel manufacturers, power supplies, automotive industries, electrical power distribution and power converters.
What Can Efficiently Designed PCB Do?
• It can increase the endurance to thermal strains
• Improve current carrying capacity
• Improve mechanical strength at connector sites and also in PTH holes
• It will let you use any material at any capability without circuit failure
• It can reduce product size by incorporating multiple copper weights on the same layer of circuitry
• The heavy copper helps to carry higher current through the board
• It can also help to transfer heat to an external heatsink
The Design Of Heavy Copper Circuits Construction
Printed circuit boards are either double-sided or multilayer typically. They are on-board high power density planar transformers. Manufactured using the combination of copper, these are made using specialized etching and plating techniques. Therefore, it features high-speed, step plating and differential etching.
Historically, heavy copper PCB is formed entirely by etching thick copper clad laminated board material. Because of the process, you can find traces of uneven sidewalls and unacceptable undercutting in PCB. The heavy coppers are seamlessly connected to standard circuits and it can be placed with minimal restriction provided by the designer. Everything falls into place when the designing of PCB is apt prior to final design.
