Product Advantages:
Strong Current-Carrying Capacity: Thick copper plating is the biggest highlight of this PCB solution. It greatly expands the cross-sectional area of circuit traces, enabling the board to safely withstand large currents ranging from tens to hundreds of amperes. This performance far surpasses conventional PCBs with standard 35um copper thickness. As a result, thick copper PCBs are the ideal choice for high-power equipment, including power supply systems and battery management systems (BMS).
Efficient Heat Dissipation: Copper naturally delivers excellent thermal conductivity. The thick copper layer acts as an embedded heat conduction path, quickly drawing away Joule heat generated by high-current operation and effectively lowering hot spot temperatures. In most application scenarios, this superior thermal performance simplifies overall structural design and even removes the need for additional heat sinks.
Enhanced Mechanical Stability: Thick copper reinforcement greatly improves the overall rigidity of the PCB substrate. It delivers stronger resistance against bending, vibration and mechanical deformation during operation. Furthermore, thick copper layers strengthen the bonding force of component pads and connectors, effectively preventing pad peeling and detachment during frequent current switching and thermal cycling.
Improved Long-Term Reliability: Thick copper plated through-holes feature thicker copper walls, which better resist thermal expansion stress and avoid cracking issues. In harsh working conditions with high current, drastic temperature changes and high humidity, thick copper PCBs maintain stable performance and offer a much longer service life compared with standard circuit boards.
