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.

Frequently Asked Questions
Can you handle complex custom designs and provide design optimization suggestions?

Absolutely. This is our core expertise. We provide free DFM analysis within 3–5 days, often helping clients achieve 15–30% cost reduction through design for manufacturability.

How do you ensure quality consistency and handle defect issues?

We implement a rigorous 4-stage QC system with 100% full inspection. Our track record shows a 99.99% qualification rate.

What are your lead times and how do you handle urgent orders?

Standard lead times: 3–7 days for prototypes, 7–15 days for mass production. We offer VIP prioritization cutting lead times by up to 30%.

Will I get timely responses and professional support throughout the project?

Yes. You get a 1v1 exclusive consultant with a 1-hour initial response commitment and 24-hour technical support.

Can you provide material certifications and environmental compliance reports?

Yes. We provide material certifications and environmental test reports (RoHS, REACH compliant) upon request.

How do you protect my designs and intellectual property?

We start with a mutual NDA and implement strict mold ownership protection and confidential data security measures.

What are your payment terms and MOQ requirements?

We offer flexible payment terms (T/T, L/C at sight) and MOQ from 1 piece for prototyping.
