What Defines High-Density Flexible Circuits?

Flexible Printed Circuits (FPCs) are engineering marvels crafted from advanced materials like polyimide (PI) with 50μm thickness or liquid crystal polymer (LCP). Unlike rigid PCBs, these circuits feature:

Microvias (≤100μm diameter) enabling 3D routing

Flex-to-rigid integration with up to 12 stacked layers

Anisotropic conductive film (ACF) bonding for zero-insertion-force connections

At Huaruixin Electronics, our 20+ years of expertise allow us to produce FPCs with 25μm line/space resolution and 0.3mm bend radii – critical for next-gen devices.
