Where is a professional manufacturer of circuit board cleaning machines in Shenzhen?

In Shenzhen Jintai ultrasound equipment Co., Ltd., rosin, solder and tin beads on the circuit board are the best cleaning methods at present, with low cost, time saving and excellent cleaning effect. I bought a Jintai ultrasonic circuit board cleaning machine before, which is very good. Just match it with the dish washing water on the market. This model is a long-term industrial machine, which is very suitable for factory use.
