Ultrasonic cleans circuit board

Using ultrasonic to clean circuit board is a kind of very good method, clean the circuit that come out board bright and clean be like new, use the principle of ultrasonic, electric energy changeover becomes mechanical vibration, and the high-pressured bleb of oscillatory generation, the circuit of bombard of cruel broken force that uses bleb board. Use this kind of method to must notice to choose the power of ultrasonic correctly, do not move electric current too greatly in cleaning a process, its power and container volume become direct ratio commonly, choose what how old ultrasonic wants a foundation to clean circuit board measure and decide, agree with only commonly the circuit of large quantities of quantities board, the solution that cleans circuit board place to use all is used commonly. Organic dissolvent, chemical banana oil, unfavorable with anhydrous alcohol (anhydrous alcohol) , otherwise circuit board will be hoar, common weighs blaze.
