Advantages of heavy copper PCB board | |
Heavy copper plate has the characteristics of carrying large current, reducing thermal strain, and good heat dissipation. 1. The heavy copper circuit board can carry large current In the case of a certain line width, increasing the copper thickness is equivalent to increasing the cross-sectional area of the circuit, which can carry a larger current, so it has the characteristic of carrying a large current. 2. Heavy copper circuit boards reduce thermal strain Copper foil has a small electrical conductivity (also called electrical resistivity ), the temperature rise is small when a large current is passed, so it can reduce the amount of heat and thereby reduce the thermal strain. Metal “conductors” are divided into: ” silver→copper→gold→aluminum→tungsten→nickel→iron ” according to conductivity. 3. The heavy 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, so it has good heat dissipation; Thermal conductivity refers to the heat transfer through an area of 1 square meter within 1H for a 1 meter thick material with a temperature difference of 1°C on both sides under stable heat transfer conditions, measured by W/m·K.  | |
