TECHNICAL FIELD

[0001] The utility model relates to welding equipment technical field, concretely is a PIN needle ultrasonic welding equipment. BACKGROUND

[0002] Ultrasonic welding is a technology that transmits high-frequency vibration waves to the surface of the object to be welded. While applying pressure, these vibration waves cause friction on the surface of the object, which in turn results in deep fusion between molecular layers. Ultrasonic welding technology involves key components such as ultrasonic generators, transducers, boosters, and welding tools. These components work together to ensure the efficiency and quality of the welding process. With the widespread application of power modules, such as IGBT (Insulated Gate Bipolar Transistor) and SiC (Silicon Carbide) power semiconductor modules, there is an unprecedented update and iteration, and higher requirements for the reliability of PIN pin connection. Although the traditional soldering process is simple and easy to operate, it has the disadvantages of easy oxidation, low welding strength, and poor reliability, which cannot meet the high requirements of modern power modules for PIN pin connection.
