Copper materials are excellent thermal conductors, so they can dissipate heat effectively and are suitable for high-power and high-temperature applications. Copper-based materials can withstand harsh working conditions and improve the durability and service life of equipment. Copper provides excellent conductivity, reduces signal attenuation, and is suitable for high-frequency and high-speed circuits.

Copper-based double-sided PCBs have high mechanical strength, can withstand physical shock and pressure, and are suitable for various environments. It can integrate a variety of electronic components to meet complex functional requirements.

Due to effective thermal conductivity, copper-based double-sided PCBs can effectively handle heat in high-power applications, reduce component temperature, and increase reliability. Double-sided layout allows more components to be laid out in a smaller space, suitable for space-constrained product design.

Widely used in LED lamps, due to its excellent heat dissipation ability, it can extend the service life of LEDs. Used in vehicle control systems, sensors and other high-power applications to adapt to vehicle working environments

Used in equipment such as motorcycle controls, inverters, power amplifiers, etc., it can effectively handle large amounts of heat.

In radio frequency (RF) and microwave applications, the high conductivity of copper-based double-sided PCBs ensures excellent signal transmission characteristics.

Used in smartphones, tablets and other portable electronic devices for battery management and PCB design.
