In the fast-evolving markets of wireless communication and smart devices, PCB spring contacts play a critical role as core micro-connection components, helping to enhance signal performance and structural stability. Yet, many products on the market struggle to balance compact size with stable performance—especially when it comes to meeting the demands of high-frequency and high-intensity usage environments for long service life and reliability. Is there a PCB spring contact that truly delivers precision dimensions, premium materials, long lifespan, and stable performance? Kinghelm provides the answer with its KH-351014-TP model, designed with unique engineering and manufactured under strict quality standards.

Kinghelm KH-351014-TP is an ultra-compact PCB spring contact measuring only 3.5 × 1.0 × 1.4 mm. Lightweight at just about 0.045 g per unit, it perfectly meets the stringent space and weight requirements of modern electronic products. Made of high-strength SUS304 stainless steel, it ensures excellent elasticity and corrosion resistance. The product also passes salt spray testing for electroplating: nickel undercoat thickness of 50–80 μ" min, with ≥1 μ" min gold plating applied separately to the soldering and contact areas. This significantly improves conductivity and effectively prevents oxidation even after prolonged use. Thanks to such high-standard processes, KH-351014-TP maintains stable contact performance and electrical conductivity even in harsh environments or during extended high-frequency operation.

Notably, the KH-351014-TP PCB spring contact is engineered with a strong focus on durability and reliability. Rigorous tests show a torsion of 45°/1000 mm under simulated assembly conditions, with arch height controlled within 5 mm/1000 mm, ensuring minimal deformation and stable structure during use. Additionally, its life test exceeds 20,000 cycles, maintaining spring force between 60 gf and 80 gf. This guarantees lasting rebound strength and contact reliability, making it ideal for applications that demand frequent mating cycles or long-term dependable conductivity—such as smartphones, tablets, in-car navigation systems, and industrial controllers where contact stability is critical.

Beyond excellent performance and process quality, the KH-351014-TP’s design also reflects Kinghelm’s deep understanding of market needs: ultra-compact packaging compatible with automated pick-and-place assembly (tape and reel packaging) for high-volume SMT processing; standardized product models and strict quality control, providing dependable support for customers' product designs. From product design and material selection to manufacturing processes and testing standards, the KH-351014-TP showcases Kinghelm’s commitment to quality and deep insight into customer demands.
