Contact Springs / Spring Fingers for Connectors - Precision Stamped
Product Overview

Tingfeng Hardware supplies precision connector spring contacts for AI infrastructure and smart hardware, including high-speed board-to-board and FPC connectors. Using high-spring materials like phosphor bronze and beryllium copper, with progressive die high-speed stamping and stress relief, stable contact force and mating cycle life ≥5000 are ensured. Micro contacts with 0.3mm pitch are supported, customizable gold/tin plating. 15 years experience ensures stable and reliable signal transmission.

Technical Description

High-speed connector springs are critical for data transmission in AI servers and liquid cooling systems. Contact design balances low insertion force and high retention force, through precise cantilever calculation and die compensation, achieving normal force range 0.2N-1.5N, contact resistance below 30mΩ. For high-speed signal transmission, contact shape is optimized to reduce reflection and crosstalk. All products undergo 100% continuity testing and visual inspection, ready for automated placement. Complete inspection reports are provided with shipments.

Machined several critical stainless steel prototypes for a micro-surgical instrument we are developing. The service lives up to its name – accuracy fully met specifications, and the speed exceeded expectations (received testable samples within a week). Communication was smooth, and they offered manufacturability suggestions on our initial design, resulting in more reliable final parts. An ideal R&D partner.
