Multilayer thick copper PCB

1. Thick copper circuit boards can carry large currents

In the case of a certain line width, increasing the copper thickness is equivalent to increasing the cross-sectional area of the circuit, so that it can carry a larger current.

2. Thick copper circuit board reduces thermal strain

Copper foil has a small conductivity, and the temperature rise is small when passing a large current, so the heat generation can be reduced, thereby reducing thermal strain.

3. Thick copper circuit board has good heat dissipation

Copper foil has high thermal conductivity (thermal conductivity 401W/mK), which can play an important role in improving heat dissipation performance.
