Metal Stamping PCB Mount Screw Terminal for electronic and electrical systems

Product Specification

PCB screw terminals are designed to provide secure, stable, and reliable wire-to-board connections for printed circuit boards. Using a precision screw clamping mechanism, they ensure strong wire fixation, low contact resistance, and easy installation, even in high-vibration environments.

The terminals are manufactured with high-conductivity copper alloy contacts to guarantee excellent electrical performance and consistent current transmission. The housing is made of UL94 V-0 flame-retardant thermoplastic, offering superior heat resistance and long-term durability. Multiple pitches, current ratings, wire ranges, and mounting options are available to meet diverse application requirements.

All PCB screw terminals are produced in-house through stamping, machining, assembly, and inspection processes, ensuring stable quality and tight tolerance control. RoHS-compliant materials are used, and OEM or custom solutions are supported for industrial, power supply, automation, and electronic control applications.

Quality control is strictly implemented throughout the production of PCB screw terminals to ensure consistent electrical and mechanical performance. All raw materials are inspected for material composition, dimensions, and RoHS compliance before production. In-process quality control is applied during stamping, tin plating, and assembly, with key checks on dimensional tolerances, clamping force, contact resistance, and plating thickness. Final inspection includes visual, mechanical, and electrical testing prior to shipment. Complete inspection records and traceability are maintained to guarantee stable quality for industrial and electronic applications.
