[0002] Currently, soldering is commonly used to connect wires and circuit boards. The disadvantages of this connection method are:

[0003] 1. Low connection efficiency; the wire needs to be initially fixed on the circuit board, such as using tweezers to press it to the welding point, and then finally fixed by welding;

[0004] 2. Poor reliability: The wires are fixed to the circuit board by welding, which increases the probability of poor soldering and reduces the reliability of the connection.

[0005] 3. High requirements for operators or equipment; the wire needs to be pressed accurately to the welding point and then welded and fixed. This has high requirements for the operator's eyesight and operating accuracy. Novices need a long period of training and practical training to meet the requirements. Summary of the Invention
