PCB 4-Leg Brass Screw Terminals for Electrical Connection
PCB screw terminals are metal connection parts mounted on printed circuit boards for electrical wiring and mechanical fixing. The terminal body is usually made from brass and finished with tin plating to improve solderability and conductivity. The threaded center hole is designed for screw fastening, while the solder legs are inserted into PCB holes and soldered in place.
