What is The Heavy Copper PCB?

Heavy Copper PCB is widely used in central power supply systems .and power electronic devices due to its ability to conduct larger currents in smaller product sizes. Generally, this unique type of heavy copper PCB features a finished copper weight of more than 4oz (140um), compared to the 1oz (35um) or 2oz (0um) copper weight generally found in those with a standard PCB copper thickness.

Due to the additional thickness of the copper circuit board, the circuit board can conduct a higher current, achieve good heat distribution and implement complex switches in the smallest of spaces. Additional advantages include increased mechanical strength at the connection points, the possibility of achieving a smaller product size by integrating several weights on the same circuit layer and the possibility of using exotic materials with maximum capacity with minimal risk of circuit failure.

  • Reduced PCB size due to reduced wired bus configurations
  • Easy integration with high-power circuits and control circuits
  • Enhanced thermal resistance reduction by adding copper plating in the thermal vias
  • Reduced layer count due to ease of adding multiple copper weights on a single layer
  • Enhanced mechanical strength of PTH holes and connector areas
  • Thick copper sheet has features such as high current carrying. reduced thermal strain, and good heat dissipation.
  • Not limited by processing temperature, blowing oxygen when the melting point is high. and hot melt welding methods such as low temperature brittleness.
  • Thick copper sheet material is fireproof and is a non-combustible material.
  • Even in a very corrosive environment. copper sheet can form a strong, non-toxic passivation protection layer.
