Product Description
Custom Stamped Contact Shrapnel for PCB Modules – Complex Anti-Vibration Spring Design
Tingfeng Hardware provides custom stamped contact shrapnel for PCB modules, specializing in complex spring arm geometries and anti-vibration design. Manufactured from phosphor bronze C5191, our shrapnel is vibration resistance compliant with IEC 60068-2-6 and rated for a cycle life of ≥50,000. With 16 years of precision manufacturing experience, we support high-volume consistency production and consumer-grade cost control, helping clients maintain connection reliability in vibrating module environments.
Product Overview
PCB modules continuously experience vibration and thermal cycling during device operation, and contact shrapnel must maintain stable elastic force and low contact resistance in dynamic environments. Our phosphor bronze shrapnel achieves vibration-resistant stable contact within limited space through complex spring arm geometry design, preventing momentary open circuits. This is exactly where standard parts fall short and non-standard customization becomes necessary.
On the commercial side, module clients need more than "functional shrapnel"—they need a supply partner that can adjust with product structure without sacrificing consistency at volume. We help clients balance R&D speed and mass-production cost through full-process SPC monitoring, tape-and-reel packaging for SMT compatibility, and flexible tooling cost-sharing arrangements.
