The technical features of cleaning the precision electron by ultrasonic cleaner
With modern electronic goods quickly to develop in the direction of the short, small, light and thin, in the electronic manufacturing process technology produced more and more nonpolar pollutants (Rosin / resin and oil, etc.), polar contaminants (activated flux agent and salt, etc.) and particulate contamination, such as fruit of these pollutants are not removed in a timely manner, form board and components of surface leakage, short circuit, open circuit or printed, and the corrosion causes the ineffectiveness of precision devices, is bound to the quality and stability of the influence to technology improvement and precision electronic devices. Therefore, it is necessary to use the cleaning process in many parts of the technology, using the cleaning agent and the supporting cleaning equipment. Along with the high density and fine of the assembly, the cleanness and precision of PCB is higher and higher, and the need of cleaning technology is also higher and higher.. Before cleaning method for cleaning of electronic precision to meet the requirements, and the use of ultrasonic cleaning technology for high precision and high cleanliness of cleaning of precision electrical and ultrasonic cleaning method has incomparable advantage of cleaning technology, especially the complex shape of the workpiece, like some of the uneven surface, a blind hole in the electronic parts, small parts, especially for high precision ultrasonic cleaning.
Ultrasonic cleaning technology to use ultrasonic cavitation generated instantaneous high pressure impact, rapid peeling off the dirt on the workpiece. Due to the cavitation bubbles, formed by the impact of fouling layer and the surface layer of the vacancies and vacancy penetration, due to the small bubbles and sound synchronization swell, shortening, repetitive physical force like peeling action on the fouling layer fouling layer layers stripped, bubble to penetrate to the Caspian, until the dirt layer was peeled off completely.
