Product Description
4-layer HASL rigid-flex PCB
The 4-layer lead-free HASL (Hot Air Solder Leveling) flex-rigid PCB merges structural adaptability with robust solder performance, engineered for reliable operation in demanding electronic systems.Constructed with a 4-layer configuration, it integrates rigid FR-4 substrates for mechanical robustness and flexible polyimide (PI) layers for superior bending capability, enabling seamless 3D integration in compact assemblies. Its standout feature is the lead-free HAL surface finish—a RoHS-compliant process that deposits a uniform tin-lead alloy (or tin-silver-copper for lead-free variants) via hot air leveling, ensuring excellent solderability, enhanced wear resistance, and strong adhesion to copper traces.
