Embodiment Construction

[0048] The implementation of the present invention will be described in more detail below with reference to the accompanying drawings and component symbols, so that those familiar with the art can implement it after studying this specification.

[0049] Such as figure 1 As shown, the preferred embodiment of the defoaming device provided by the present invention includes a body 1 and a vacuum generator 2 . Wherein, the interior of the body 1 is divided into a first space 10A and a second space 10B by a vertical plate 11, so that the first space 10A and the second space 10B are respectively located on the right and left sides of the interior of the body 1, And the first space 10A and the second space 10B can make the air flow communicate with each other in some parts, for example, a ventilation hole 121 can be formed at a higher position of the vertical plate 12, so that the gas can flow from the first space 10A to the second space 10B , but the liquid flowing downward cannot o...

Abstract

The invention discloses a defoaming device which is suitable for a DES manufacturing process of a PCB, and the defoaming device is arranged on an auxiliary groove outside a developing groove of the DES manufacturing process. The defoaming device comprises a body and a vacuum generator, a foam breaking area and a liquid outlet area are arranged in the body, and the body is provided with an exhaust port and a liquid inlet located above the foam breaking area. When the vacuum generator operates, negative pressure is generated in the body through the exhaust port, then a liquid medicine solution generating foams in the auxiliary tank is sucked into the body through a first pipeline, the liquid medicine solution is discharged through the liquid outlet area after foams of the liquid medicine solution are eliminated through the foam breaking area, and the discharged liquid medicine solution is recycled and conveyed to the developing groove for use after being filtered.

Description

technical field [0001] The present invention relates to a defoaming device used in the manufacturing process of the outer layer development etching stripping line (hereinafter referred to as "DES") of a printed circuit board (Printed Circuit Board, hereinafter referred to as "PCB"). Background technique [0002] The DES manufacturing process of PCB in the chemical wet manufacturing process needs to use a large amount of dissolving liquid (sodium carbonate solution) in the developing tank to dissolve the ink and other substances on the PCB. More and more, the concentration of the dissolving potion also decreases, resulting in worsening effect of dissolving, and the dissolving potion will produce a large amount of foam in the developing tank and overflow from time to time because it is too late to dissolve the ink and impurities. [0003] In the face of the problem of a large amount of foam overflowing from the developing tank, the existing solution is to add a connected auxil...
