Product Description

ENIG Thick Copper PCB Highly Efficient Thermal Conduction Inverter

 

♦ What is Thick copper PCB


 

Thick copper PCB refers to a circuit board formed by bonding a layer of copper foil with a thickness of 2 ounces (oz, about 62.5 microns) or more to FR-4 or other substrates during the printed circuit board (PCB) manufacturing process.

Features of Thick Copper PCB

    • ​​Excellent conductivity​​: Thick copper improves current flow, lowers resistance, supports high-power/high-frequency circuits, and boosts speed/reliability.

    • ​​Strong load capacity​​: Thicker foil increases rigidity, resists pressure/bending/thermal stress, and suits harsh environments.

    • ​​Efficient heat dissipation​​: Rapid heat spreading reduces thermal stress, ensures stable operation of high-power devices, and extends lifespan.

    • ​​High thermal stability​​: Minimizes heat buildup, maintaining performance at high temperatures.

    • ​​Design flexibility​​: Enables wider traces and tighter spacing for complex/high-density circuits.

 

Applications of Thick Copper PCB

    • ​​Power supply equipment: high-power switching power supply, inverter, UPS, etc.
    • ​​Automotive electronics: electric vehicle motor controller, on-board charger, battery management system.
    • ​​Industrial control: motor driver, servo controller, welding equipment.
    • ​​New energy field: photovoltaic inverter, wind power converter.
    • High-power LED lighting: LED driver board that needs heat dissipation and current carrying

 

​​Copper Thickness Selection Basis

    • 1-2oz: conventional power modules, medium current circuits (<50A).

    • 3-4oz: high power LED drivers, inverters (50-100A).

    • 5oz and above: electric vehicle inverters, photovoltaic combiner boxes (>100A).
