[0021] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] A technology for three-proof treatment of circuit boards using ultrasonic waves, characterized in that it includes the following steps:
[0023] Step (1) Set up the circuit boards in the cleaning tank in an orderly manner, inject a special cleaning agent for circuit boards or an environmentally friendly electronic ultrasonic cleaning agent into the cleaning tank, and completely soak the circuit boards in the tank; turn on the ultrasonic generator to generate high-pressure air bubbles, After ultrasonic cleaning for 20-30 minutes, disconnect the ultrasonic generator and take out the circuit board. Stand neatly on a stand and drain the cleaning agent.
[0024] Step (2) Put the cleaned and filtered circuit boards into the oven, and the loading quantity shall be half ...
