Thick copper PCB clone power circuit copy is a professional reverse engineering and duplication service for highcurrent thick copper power circuit boards. Thick copper PCBs generally adopt copper foil with a thickness of more than 2oz, and some highpower boards use 4oz10oz thick copper layers, which have ultrastrong current bearing capacity and overload resistance. They are mainly used in highpower power equipment, industrial frequency conversion equipment, new energy power supply systems, power distribution equipment, and heavyduty electrical control circuits. The core of thick copper power circuit cloning is to accurately replicate the thick copper laying structure, highcurrent circuit parameters, and heat dissipation design of the original board to ensure the cloned board meets highcurrent and highload operating requirements.

Different from ordinary thin copper PCB duplication, thick copper PCB clone has strict requirements on structural parameters and process restoration. Our technical team focuses on detecting and restoring the core parameters of thick copper power boards, including copper foil thickness, thick copper laying area, trace thickness and width, highcurrent via aperture, and copper plating thickness. We use professional thickness detection equipment and circuit analysis technology to accurately record the current load capacity of each circuit, the heat dissipation design of thick copper areas, and the connection mode of highpower components, avoiding the problem of insufficient current bearing capacity of the cloned board caused by inaccurate copper layer parameter restoration.

In the file restoration and design optimization stage, we fully restore the highpower circuit logic such as main current circuit, shunt circuit, and overload protection circuit of the original thick copper board. According to the original board’s thick copper process parameters, we calibrate the copper laying thickness and trace width of key currentcarrying circuits to ensure the circuit can bear high current impact and longterm stable operation. For the heat dissipation design of thick copper boards, we completely replicate the original board’s thick copper heat dissipation paving, hollow heat dissipation, and component heat dissipation layout, and optimize the local copper layer structure to improve the overall heat dissipation and overload resistance of the board. At the same time, we check and optimize the via copper plating thickness and distribution to ensure smooth highcurrent conduction.

The prototype testing of thick copper power PCBs focuses on highload performance verification. We conduct ultralong highcurrent load testing, overload impact testing, hightemperature aging testing, and circuit stability testing on the cloned boards to verify that the thick copper circuit has no heating, burnout, or voltage drop problems under rated highcurrent operating conditions. All cloned thick copper PCBs adopt highpurity thick copper foil and hightemperature resistant insulating substrates, with excellent electrical conductivity and thermal stability. This service supports the duplication of singlelayer and multilayer thick copper power boards, and can customize thick copper thickness and circuit load parameters according to customer equipment power requirements, providing reliable circuit duplication solutions for industrial highpower electrical equipment.
