Product Description
Custom Lightweight Stamped Contact Shrapnel for PCB & Electronic Assemblies
Tingfeng Hardware provides custom lightweight stamped contact shrapnel for PCBs and electronic assemblies, specializing in complex thin-wall design. Manufactured from phosphor bronze C5191 with selective gold plating, each piece weighs ≤0.5g and delivers vibration resistance compliant with IEC 60068-2-6. With 16 years of precision manufacturing experience, our 5–7 day rapid prototyping matches the fast iteration pace of consumer electronics and miniaturized devices.
Product Overview
Contact shrapnel in PCBs and electronic assemblies must achieve stable elastic force on ultra-thin materials while controlling per-piece weight. Our phosphor bronze springs achieve complex thin-wall forming on 0.05–0.2mm thin materials, selective gold plating controls contact resistance to ≤10mΩ, and per-piece weight is ≤0.5g. This is exactly the realm many stamping factories view as hard-to-make and avoid. On the commercial side, miniaturized electronics are a fast-iterating, price-competitive, yet reliability-non-negotiable category. Clients need a supplier that can respond quickly to non-standard design changes, maintain contact reliability under lightweight constraints, and understand consumer electronics cost structures.
