PCB Mounting Pins | Cold-Formed Precision | Manufacturer

The two main types of PCB mounting are through-hole mounting and surface mount technology (SMT). Through-hole mounting involves inserting pin leads through drilled holes and soldering on the opposite side, offering strong mechanical bonds. Press-fit is a through-hole variant that uses interference-fit retention features — such as stars or splines — to secure pins without solder, ideal for high-vibration environments.

Electropin offers four retention feature options: Star, Tabs (Spline), Inscribed Square, and Flat. The star feature can expand diameter up to 50% greater than the wire raw material, providing strong anti-rotation and pull-out resistance. These features are available across connector, barbed, press-fit, grooved, and other pin types.

Electropin manufactures pins in lead-free brass and stainless steel. Lead-free brass offers excellent conductivity and ease of forming, while stainless steel provides superior hardness and corrosion resistance. Both materials are available without leaded alloys, ensuring REACH and RoHS compliance without requiring additional processing steps.

Electropin can begin manufacturing and deliver a first batch of cold-formed pins in as little as two weeks when raw materials are available. Subsequent production batches are delivered on a customer-specified timeline, and production volume can be scaled dramatically when demand changes, thanks to high-speed automatic die rolling that produces up to 5 pins per second.

Yes. Electropin's grooved and hinge pins are specifically designed to work in high-speed automation environments where pins slide down tracks without requiring orientation. The consistent geometry ensured by cold-forming — with no tool dulling — means every pin behaves identically in automated feeders, reducing jams and assembly errors at scale.

Yes. Electropin offers a full Design for Manufacturing (DFM) consultation and custom pin design refinement service. Engineers collaborate with customers to optimize pin geometry for their specific circuit board, plastic housing, or metal press-fit application. Custom die molds are created for unique designs, and production can begin in as little as two weeks after design finalization.
