Flexible PCB Fabrication
As an expert of electronic manufacturing services, PCBBOX is offering flexible PCBs to global customers with excellent quality and cost efficiency, which are widely applied in compact devices. Flexible PCBs, also known as flex PCBs or flexible printed circuit boards, are a type of PCB that can bend and flex to fit into various shapes and spaces with advantages:
1. Flexibility: Can be bent, folded, or twisted to fit into compact spaces.
2. Lightweight: Reduces the overall weight of the electronic device.
3. Durability: Resistant to vibration and mechanical stress.
4. Reduced Connections: Fewer connectors and solder joints, reducing potential points of failure.
