Custom Services for 6oz Thick Copper Circuit Boards
1. Features and Advantages of 6oz Thick Copper Circuit Boards
1. High Current Carrying Capacity:
– 6oz thick copper (approximately 170μm) significantly enhances the PCB‘s current carrying capacity, reducing resistance losses and heat generation caused by excessive current.
– Suitable for high-power, high-current electronic devices such as power modules and servo drivers.
2. Excellent Heat Dissipation Performance:
– The thick copper layer effectively conducts heat, lowering the operating temperature of components and improving system stability and lifespan.
3. Higher Mechanical Strength:
– The thicker copper layer increases the mechanical strength of the PCB, making it more stable in harsh environments (such as vibration and impact).
4. Enhanced Routing Capability:
– 6oz thick copper circuit boards support complex and refined circuit layouts, better achieving power layer and ground layer separation, reducing noise interference.
5. High Reliability:
– Thick copper PCBs perform excellently in high current and high power environments, suitable for high-end applications in military, aerospace, power, and automotive sectors.
