SMT Pins | High-Speed Cold-Form Manufacturing | Precision Supplier

Electropin manufactures SMT pins primarily in lead-free brass and stainless steel. Both materials are available across all pin types — solid contact, knurled, dowel, barbed, hinge, grooved, press-fit, and custom designs — and are fully REACH and RoHS compliant, eliminating regulatory concerns without requiring leaded brass like machined alternatives.

Electropin offers four retention feature profiles: Star, Tabs/Spline, Inscribed Square, and Flat. The Star feature can expand the effective pin diameter up to 50% beyond the wire raw material diameter, making it ideal for high-retention press-fit into metal or post-insertion into molded plastic parts requiring anti-rotation performance.

Using proprietary automatic die rolling technology, Electropin produces up to 5 custom connector pins per second. This high-speed cold-forming process is scalable — production volumes can be dramatically increased when demand changes — and the first batch can be ready for delivery in as little as two weeks from project start.

Electropin achieves an industry-leading defect rate of just 1 pin per 600,000,000 produced. Because automatic die rolling does not use cutting tools that dull over time, dimensional consistency is maintained from the very first pin to the millionth, ensuring uniform quality throughout the entire production run.

Yes. All pins are manufactured using lead-free materials, which inherently satisfies both REACH and RoHS regulatory requirements. Unlike machined parts that often require leaded brass for machinability, Electropin's cold-forming process works with lead-free brass and stainless steel, eliminating compliance risk for automotive, medical, and electronics OEMs.

Electropin's pins support three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic parts. Select hinge and grooved pin designs also support high-speed automation assembly, where pins slide down tracks without needing orientation, further reducing assembly time and cost.
