2L 120W Timer Heater Adjustable Clean Digital Portable Mini Industrial Ultrasonic Stainless Steel Tank For Pcb Cleaner

Electronic industry ultrasonic cleaning machine: cleaning of PCB circuit boards. In China’s electronics industry, the vast majority of enterprises are using PCBs. The soldering fluxes used for PCB component welding are divided into three types: water-soluble, rosin, and non cleaning. The first two types are more commonly used, and ultrasonic cleaning is often used (some also use alcohol brushing). Non cleaning types should not be cleaned in principle. However, currently, most manufacturers around the world still need to clean even if they use non cleaning soldering fluxes to weld components. Especially if high-density PCBs and high-density IC pins are not cleaned or ultrasonic cleaning is not used, it will inevitably lead to dust adsorption between high-density lines and IC pins. Once the environmental humidity is high, it is easy to cause short circuits between high-density lines and pins, leading to faults. Once the environment is dry, the short circuit fault will disappear on its own, making it difficult to find such faults. So electronic equipment factories around the world insist on ultrasonic cleaning of PCB boards. In China, military electronic equipment factories have begun to promote and have received dual benefits, which not only improve product reliability but also reduce after-sales service costs.
