During Flexible Printed Circuit (FPC) multi-layer lamination and Coverlay encapsulation, tooling consumables are exposed to extreme cyclical thermodynamic loading. When vacuum quick presses stamp under severe conditions (200°C, 5 MPa), materials must deliver not only high isotropic pressure equalization to wrap ultra-fine pitch conductors safely, but also exceptional interfacial stability across the heterogeneous steel-to-elastomer boundaries.

During Flexible Printed Circuit (FPC) multi-layer lamination and Coverlay encapsulation, adhesive matrices transfer into low-viscosity fluids under process temperatures (160°C – 200°C). Generating absolute thermal uniformity while providing optimized hydro-damping to secure the resin flow boundary is vital to prevent pad contamination. The Silicone Iron Pad, acting as a rigid-flexible thermal structural medium, governs the […]

FPC Manufacturing Process Overview Substrate PreparationPolyimide (PI) or PET films are selected as the base material. They are cleaned and dried to ensure a dust-free and oil-free surface. Circuit PatterningCopper is patterned onto the substrate through etching or plating, forming the required conductive traces. Drilling & PlatingHoles are drilled where interconnections are needed, followed by […]
