Surface Mount PCB Screw Terminal Electrical Connector RoHS Compliant Custom Designs

The PCB screw terminal is a reliable electrical connector designed for secure wire connections on printed circuit boards. Using a screw clamping mechanism, it provides stable wire fixation, low contact resistance, and long-term electrical performance for industrial and electronic applications.

Manufactured from high-quality conductive materials such as brass, phosphor bronze, or copper, PCB screw terminals offer excellent conductivity and mechanical strength. Precision metal stamping and forming processes ensure consistent dimensions, accurate contact interfaces, and stable performance during mass production.

Available in single-pole or multi-pole configurations, with vertical or right-angle designs, PCB screw terminals support both through-hole and surface-mount assembly. Surface plating options including tin, nickel, or silver enhance solderability, corrosion resistance, and contact reliability.

PCB screw terminals are widely used in power supplies, industrial control systems, automation equipment, inverters, and lighting control applications. OEM and ODM customization is supported to meet specific electrical and mechanical requirements.

Applications of PCB Screw Terminals

PCB screw terminals are widely used in electronic and electrical systems where secure, reliable, and serviceable wire connections are required. The screw clamping design allows easy wiring, stable contact pressure, and convenient maintenance, making them suitable for both industrial and commercial applications.
