Heavy Copper PCB

Definition of Heavy copper circuit board
Heavy copper circuit board refers to the printed circuit board with copper thickness ≥ 2oz on the inner or outer layer. Under the condition of standardizing the design circuit line width and line spacing, increasing the copper thickness is equivalent to increasing the circuit cross-sectional area, which can carry larger Current, copper foil has a small electrical conductivity, and the temperature rise is small under the condition of high current, so the heat generation can be reduced, thereby reducing thermal strain, in addition, copper foil also has high thermal conductivity (thermal conductivity 401W/mK), It can play an important role in improving the heat dissipation performance, so the thick copper circuit board has the characteristics of carrying large current, reducing thermal strain and good heat dissipation.
Copper Inlay PCB
Copper inlay PCB is made of FR4 and heat-dissipating metal materials(MCPCB). This process is realized by embedding copper metal in the circuit board. The heat emitted by the heating element installed on the circuit board can be embedded into the radiator on the bottom side through copper.

Applications:
As automotive electronics, battery charger and monitoring system, power planar transformer and the rapid development of electric power communication technology, more than 5 oz to 20 oz and gradually become a kind of super thick copper foil board has a broad market prospect of application, the special PCB printed circuit board not only for the electrical connection in the electronic components to provide necessary and mechanical support, Also can provide high current and high reliability of ultra thick copper foil printed board.
Applications of Heavy copper pcb: Aerospace, Satellite Communication, Network base load station, Hybrid integrated circuit, Power supply automotive electronics, Battery charger and monitoring system, Power planar transformer, Electric vehicle charging solution infrastructure, Charging Station or Charging Point，Led Lighting and other high-tech field.
