1. Design considerations

　　Firstly, before starting the design, it is necessary to understand the copper PCB specified in the design guidelines.

　　From the shared guidelines, it can be understood that it includes considerations such as line width, line spacing, and heat release mode. The increased copper thickness requires wider wiring to accommodate higher currents, and appropriate spacing is crucial for avoiding hot spots and ensuring reliable operation. In addition, selecting suitable materials with excellent mechanical strength and thermal performance is crucial for ensuring robustness.

　　2. Material selection

　　Careful attention must be paid to the etching process to prevent excessive etching, which may damage the integrity of the copper layer. In addition, the additional weight of copper requires a sturdy substrate to support the structure of the board.

　　You may have a question why industrial power supplies require the use of thick copper plates because they have exceptional heat dissipation and conductivity: one of the outstanding features of thick copper plates is their unparalleled heat dissipation ability. The increased copper thickness serves as a powerful conductor, effectively guiding heat away from power components. This special heat dissipation prevents thermal stress and ensures the lifespan and reliability of industrial power systems. In addition, the high conductivity of thick copper PCB enables efficient power transmission, reduces losses, and improves overall system efficiency.

　　3. Production challenges

　　In addition, thick copper PCBs undergo rigorous testing to ensure optimal performance in industrial power applications. Inductance testing has verified the effectiveness of copper layers in reducing magnetic interference. Capacitance testing evaluates the ability of PCBs to store electrical energy, while resistance testing determines the conductivity and resistance of copper wiring. These tests play a crucial role in verifying the quality and performance of heavy copper PCBs in demanding power supply scenarios.

　　Thick copper PCB is widely used in the field of industrial power supply, especially in the production of sturdy and efficient power control products. They are indispensable components in industrial power converters, motor drives, uninterruptible power supplies (UPS), and various automation systems. The excellent heat dissipation and high current carrying capacity of thick copper PCB make it an ideal choice for handling the power demand of these applications, ensuring reliable and efficient power transmission.
