Embodiment 1

[0024] figure 1 The printed circuit board wet process manufacturing system provided by Embodiment 1 of the present invention is shown. The printed circuit board wet process production system 10 includes water-saving equipment 11 and a water washing tank 12 located on the printed circuit board production line. A flying target sensor module 120 and an electronic flowmeter 121 are installed at the water washing tank 12; the water-saving equipment 11 includes an electric control component 110 and a water control cabinet 112, and the water control cabinet 112 includes a water replenishment electronic valve 1121, and when the water replenishment electronic valve 1121 is opened, the water The water control cabinet 112 supplies water to the outside, and when the water supply electronic valve 1121 is closed, the water control cabinet 112 stops the external water supply; the water control cabinet 112 and the water washing tank 12 are connected by water pipes.

Embodiment 2

[0040] like image 3 As shown, the printed circuit board wet process manufacturing method is applied to the printed circuit board wet process manufacturing system 10 of Embodiment 1, which specifically includes the following steps 101 to 104, which are described in detail as follows:

[0041] Step 101: After the valve of the air pipe connected to the washing tank 12 is opened until the air pipe is full of gas, the electric control unit 110 controls the water control cabinet 112 to inject water into the washing tank 12 through the water pipe; after the washing tank 12 is filled with water, discharge the washing tank 12 the water in the tank, and close the valve of the air pipe after the draining is completed.

[0042] Wherein, this step 101 is to ensure the effective use of the air pipe connected to the washing tank 12 and prevent the pores from being blocked by impurities and foreign matter.

[0043] Step 102: After the air pipe valve is closed, the flying target sensing modu...

Abstract

The invention is applicable to the technical field of printed circuit boards and provides a printed circuit board wet process production system and method. The method comprises the steps that: after avalve of a gas pipe connected to a water washing tank is opened such that the gas pipe is filled with gas, an electronic control component controls a water control cabinet to fill the water washing tank with water through a water pipe; after the water washing tank is filled with the water, the water in the water washing tank is discharged, and the valve of the gas pipe is closed after the drainage is completed; a fly target sensing module identifies the presence or absence of a flying target in the water washing tank after the valve of the gas pipe is closed, generates a corresponding identification signal and outputs the identification signal to the electronic control component; the electronic control component controls the opening or closing of a water supplement electronic valve basedon the identification signal; and when the electronic control component controls the water supplement electronic valve to be opened, an electronic flow meter monitors the water flow at a water inlet of the water washing tank, generates a corresponding feedback signal and outputs the feedback signal to the electronic control component, and the electronic control component controls the output waterflow of the water control cabinet according to the feedback signal.

Description

technical field [0001] The invention belongs to the technical field of printed circuit boards, and in particular relates to a wet-process production system and method for printed circuit boards. Background technique [0002] With the continuous development and growth of printed circuit board enterprises, the water consumption is also gradually increasing. In the traditional wet process manufacturing process, the liquid medicine left on the workpiece in the previous liquid tank is cleaned through the water washing tank, and then the water washing tank is maintained by replenishing water. However, the traditional continuous replenishment of water wastes a lot of water resources, and is subject to fluctuations in water pressure. The flow rate of pressurized replenishment water fluctuates from high to low. When the flow rate is too high, water is wasted. When the flow rate is too low, the water washing tank cannot be maintained. cleanliness. [0003] Therefore, the current wate...
