Thick copper plate is a special type of printed circuit board, and its copper foil thickness is much thicker than ordinary PCB. You may ask, why use thick copper plates? What's in it for you? In fact, the thick copper plate is widely used, and it can meet some special circuit needs, such as:
High current: Thick copper plates can carry higher currents, which improves the performance and reliability of the circuit. Thick copper plates can be used in some high-power equipment, such as electric vehicles, solar panels, wind turbines, etc.
Reduced thermal strain: Thick copper plates can effectively disperse and conduct heat, thereby reducing the thermal strain of the circuit. Thermal strain refers to the temperature change produced by the circuit during operation, which can lead to the deformation and damage of the circuit. Thick copper plates can reduce the thermal strain of the circuit and prolong the life of the circuit.
Good heat dissipation: Thick copper plates can be used as part of the heat sink to help the circuit dissipate excess heat. This can avoid overheating of the circuit and keep the circuit stable and safe. Thick copper plates can be used in some high-temperature environments, such as aerospace, military, medical, etc.
You may also be wondering, how thick is the thick copper plate? Generally speaking, when the thickness of the copper foil is greater than or equal to 2oz (70 m), it can be called a thick copper plate. However, some manufacturers can offer thicker copper plates, even up to 20 ounces square feet (26.).8 mils or 034 mm) of extremely heavy copper. These thick copper plates can cope with more extreme circuit needs, such as ultra-high current, ultra-high temperature, etc.
