High-Performance 4 Layer Flexible PCB Solutions for Advanced Electronics
Our 4 layer flex PCBs deliver exceptional performance and reliability for complex electronic applications requiring flexible circuit solutions. These multi-layer flexible printed circuit boards combine superior bendability with enhanced electrical capabilities, making them ideal for space-constrained designs and dynamic applications.
Key Features & Benefits
Advanced Multi-Layer Construction: Four precisely engineered copper layers provide excellent signal integrity and power distribution while maintaining the flexibility essential for modern electronic devices. The optimized layer stackup ensures minimal signal loss and superior electromagnetic compatibility.
Superior Flexibility & Durability: Manufactured using high-grade polyimide substrates, our flex PCBs withstand thousands of bend cycles without performance degradation. The flexible design eliminates the need for connectors and cables, reducing assembly costs and improving reliability.
Precise Manufacturing Standards: Built to IPC-6013 Class 3 standards with tight tolerances, our 4 layer flexible circuits feature minimum trace widths down to 3 mil (0.075mm) and via sizes as small as 4 mil (0.1mm). Advanced impedance control ensures consistent 50ฮฉ and 100ฮฉ differential pairs.
Versatile Applications: Perfect for smartphones, tablets, medical devices, automotive electronics, aerospace systems, wearable technology, and industrial equipment. The compact profile and 3D routing capabilities make these flex PCBs essential for next-generation electronic designs.
