Abstract

The invention relates to the technical field of PCB production, and specifically discloses a control method and a device for a PCB ultrasonic backwashing device. The control method of the PCB ultrasonic backwashing device is applied to the ultrasonic backwashing device, wherein a plurality of ultrasonic vibration plates are arranged in the ultrasonic cylinder, and the method includes: grouping the plurality of ultrasonic vibration plates to form a plurality of ultrasonic vibration plate groups, The multiple ultrasonic vibration plate groups work according to the set time sequence, and the time for the multiple ultrasonic vibration plate groups to work at the same time does not exceed the preset time. The control method of the PCB ultrasonic backwashing device provided by the present invention controls the time that the ultrasonic vibration plates work at the same time not to exceed a preset time, reduces the resonance area of ​​the ultrasonic waves generated by multiple ultrasonic vibration plates, and does not always face one place of the PCB impact, thereby avoiding the problem of damage to the panel or the edge of the hole ring of the PCB due to the mutual impact or resonance impact of the ultrasonic waves emitted by the ultrasonic vibration plate, and the panel and the edge of the hole ring of the PCB will not be corroded.

Description

technical field [0001] The invention relates to the technical field of PCB production, in particular to a control method and device for a PCB ultrasonic backwashing device. Background technique [0002] In the field of PCB production technology, ultrasonic backwashing technology is widely used. However, when cleaning the surface attachments of the PCB by the ultrasonic backwashing device, there is a problem that the copper surface of the board surface or the edge of the hole ring is corroded, especially on the board with a high aspect ratio. In the prior art, a certain number of ultrasonic vibration plates are usually installed on the edge of the ultrasonic cylinder, and all the ultrasonic vibration plates are turned on for cleaning at the same time according to the set power and cleaning time. Resonance shock. Therefore, there is an urgent need to provide a control method of a PCB ultrasonic backwash device to solve the above problems. SUMMARY OF THE INVENTION [0003]...
