Problems solved by technology

[0002] The main cause of damage to electronic components with circuit boards is the open circuit caused by corrosion of the connection between the electronic components and the circuit board caused by water ingress. The current maintenance work process is to use a hot air blower to remove the electronic components from the circuit board and then remove the circuit board. Soak in a predetermined cleaning solution for a predetermined time, and then use a brush to scrub the circuit board. In this

Abstract

The invention discloses circuit board cleaning equipment and a cleaning method, and belongs to the field of printed circuits. The circuit board cleaning equipment comprises a cleaning container, a clamping assembly and a fluid power assembly, wherein the cleaning container contains a predetermined amount of cleaning solution; the clamping assembly is connected with the cleaning container; the fluid power assembly is communicated with the cleaning container, and applies a flowing force to the cleaning solution in the cleaning container, so that the cleaning solution flows according to a predetermined path; the clamping assembly fixes a circuit board, and places the circuit board in the cleaning solution of the cleaning container; and a cleaning area of the circuit board is positioned on the flowing path of the cleaning solution. When outer-layer rust in the cleaning area of the circuit board is removed and softened to a predetermined degree, the outer-layer rust is washed away by using the flowing speed of the cleaning solution, so that the cleaning solution reacts with inner-layer rust, the rust removing quality is improved, the circuit board dipping time is shortened, and the secondary damage to a circuit board protection layer is prevented.

Description

Technical field [0001] The present invention is in the field of printed circuits, in particular circuit board cleaning apparatus and a cleaning method. Background technique [0002] Mainly due to a circuit board having the electronic component damage caused by water is connected to the open circuit corrosion electronic component and the circuit board caused by the flow of the maintenance work is the use of conventional hot air to remove the electronic component from the circuit board after the circuit board soaking a predetermined washing solution at a predetermined time, and then use the scrub brush on the circuit board, there is only the outer layer of rust which is cleared softened soaking time is reached during the immersion of the circuit board, but not the inner layer with the cleaning solution the reaction occurs, soaking, there is a problem of secondary damage caused by a protective layer of the circuit board, it is necessary to provide a quality improving remove rust and...
