Product: Silverplated copper singlehead soldering terminal circular weld washer (welding sheet) Key benefits Reliable low and pressure sealing: designed to maintain a secure mechanical and electrical joint under varying pressure conditions. and lowtemperature capability: retains sealing and soldering performance across wide temperature changes during operation and assembly. Secure, repeatable solder joints: singlehead terminal and circular weld washer shape simplify soldering and spotwelding for consistent connections. Good conductivity and corrosion resistance: silverplated copper provides reliable electrical contact and improved surface durability compared with plain copper. Multiple sizes for precise fit: available in M2.2, M2.7, M3.2, M4.2, M5.5, M6.2 to match standard screw and stud dimensions, reducing the need for adapters or rework. Function and compatibility Function: acts as a soldering terminal and circular weld washer to create sealed, electrically conductive joints between wires, components, and chassis or motor housings. Compatibility: suitable for micro motors, recorder mechanisms, VCD/DVD players, fans, copiers, printers, and similar small electromechanical assemblies where a compact, reliable solder/weld terminal is required. Performance highlights Singlehead design for focused solder application and faster assembly. Circular washer form allows secure mechanical fastening plus a reliable electrical path. Silver plating improves contact quality and helps resist oxidation at the joint. Typical use scenarios Micro motor assembly: solder the motor lead to the terminal washer and fasten with the appropriate screw (M2.2–M6.2) to ensure a sealed, conductive connection that tolerates motor heat and vibration. Optical drive and recorder : worn terminals in VCD/DVD or recorder movements to restore consistent grounding and signal continuity while preserving sealing under pressure and temperature variation. Printer/copier/fan installation: use as a welding sheet or soldering terminal where space is limited, providing a stable electrical connection between wiring harnesses and chassis grounding points. Ordering and selection tips Choose the size (M2.2, M2.7, M3.2, M4.2, M5.5, M6.2) that matches the screw or stud used in your device for proper mechanical fit and sealing. Use standard soldering or spotwelding processes compatible with silverplated copper; follow normal temperature control practices to maintain plating integrity. Materials and form factor Material: silverplated copper. Form: singlehead soldering terminal integrated with a circular weld washer (welding sheet). This component is intended for applications requiring compact, reliable soldered or welded electrical connections with good sealing and temperature resilience.
