Ultrasonic waves can be used to weld thermoplastic workpieces by welding, riveting, forming welding or spot welding. Ultrasonic welding equipment can be operated independently or used in an automated production environment. Those plastic parts with built-in precision electronic components, such as micro switches, are suitable for ultrasonic welding. At the same time, more than one method may be used to process the finished product, such as welding floppy disks and cassettes with riveting welding on the inside, and welding on the outside.

Ultrasonic cleaner for electronics industry:PCB circuit board cleaning. In my country’s electronics industry, most companies use PCBs. The fluxes used for PCB component soldering are divided into three types: water-soluble, rosin-type and no-cleaning. Many use alcohol scrubbing). The no-clean type should not be cleaned in principle. However, most manufacturers in the world still need to clean even if they use no-clean flux to solder components. Especially for high-density PCBs and high-density IC pins that are not cleaned or ultrasonically cleaned, it will inevitably cause dust to be absorbed between the high-density circuits and IC pins. Once the environmental humidity is high, high-density lines and pins are prone to occur. If the environment is dry, the short-circuit fault disappears by itself, and this type of fault is not easy to find. Therefore, electronic complete machine factories all over the world insist on ultrasonic cleaning of PCB boards. In our country, the military electronics factory has begun to promote it, and has received the double benefits of improving product reliability and reducing after-sales service costs.
