Heavy Copper PCB

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 manufacturers which can provide
the most professional products and services.

Advantages of Thick Copper PCB
Thick copper PCB is widely used in

various household appliances

high-tech products

military

medical

oth , er electronic equipment.

The application of china heavy 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.
