Product Description
Ultra-Miniature Custom Stamped Spring Contacts for PCB Assemblies
Tingfeng Hardware provides ultra-miniature custom stamped spring contacts for PCB assemblies, specializing in hard-to-make micro parts. We work with materials as thin as 0.03mm, hold tolerances to ±0.005mm, apply selective gold plating, and control contact resistance to ≤10mΩ. With 16 years of precision manufacturing experience, we support 5–7 day rapid prototyping and high-consistency mass production. The triple pressure of extreme dimensions, cost, and iteration speed in miniaturized electronic assemblies is exactly what our process and commercial model are designed for.
Product Overview
Ultra-miniature spring contacts in PCB assemblies must provide stable elastic contact within fractions of a millimeter. Our ultra-miniature custom contacts use 0.03–0.15mm thin materials, micro-precision stamped, with selective gold plating controlling contact resistance below 10mΩ — exactly the realm many stamping factories view as hard-to-make and avoid. On the commercial side, miniaturized assemblies are a market that relentlessly pursues smaller, thinner, and lighter products while remaining highly price-sensitive. Clients need more than a supplier that "can make it small" — they need a partner that maintains batch consistency at extreme dimensions and offers flexible commercial terms.
