Product Introduction

The four-layer rigid-flex PCB provided by Mingzhenghong Electronics combines the characteristics of flexible and rigid PCBs and is suitable for applications requiring high flexibility. The surface treatment uses OSP (organic anti-rust film) + ENIG (electrodeposited nickel/immersion gold), which increases conductivity and corrosion resistance while ensuring weldability. The product specifically adopts a 2OZ copper thickness design, which is suitable for high-power environments, and the special stacking design can meet the needs of different impedance values. The four-layer rigid-flex PCB is widely used in power supplies, 5G CPE equipment, antennas and other fields. Through precision design and manufacturing, Mingzhenghong provides customers with high-reliability and high-performance PCB solutions.
