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.

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.
