PCBs with a copper thickness of more than 70um are called thick copper PCBs, sometimes also called thick copper PCBs. Copper thickness typically varies from 105 to 400 µm. The thicker the copper, the higher the power dissipation of the board. These thick copper plates are used for high current output and improved thermal management. Thick copper makes it possible to create boards with cross-sections for high current loads, which also facilitates heat dissipation. Greenstone is one of the China heavy copper pcb heavy copper pcb manufacturers which can provide the most professional products and services.
Thick copper PCB is widely used in
various household appliances
high-tech products
military
medical
other electronic equipment.
The application of thick copper PCB makes the core component of electronic equipment products-circuit boards have a longer service life, and at the same time it is very helpful to the size reduction of electronic equipment.
