1. Small motor windings are usually made of highly conductive copper materials, with winding copper wires of fine diameter (such as 0.1-1mm), requiring precise control of heat input to avoid melting or insulation layer carbonization. Blue light laser welding has the advantages of high absorption rate, high energy density, no spatter, small heat affected zone, and small welding deformation, making it suitable for connecting stator windings, copper wires, and precision components.
2. Copper foil has good conductivity, thermal conductivity, and certain flexibility, and is used in efficient heat sinks for communication equipment, PCB boards, and electrical devices. Infrared lasers cannot achieve thermal conduction welding of copper, so copper foil welding is prone to problems such as welding through. Blue light can achieve thermal conduction welding of purple copper, with controllable melting depth, no spatter during the welding process, good welding quality, and high welding efficiency.

3. FPC (Flexible Printed Circuit) soldering is used to electrically connect and mechanically fix a flexible printed circuit board to other electronic components or circuit boards.
