A positioning device for electronic circuit board etching

Abstract

The invention belongs to the technical field of circuit boards, and in particular relates to a positioning device for etching electronic circuit boards, comprising a bottom plate, a lifting device and a first vertical plate are fixedly connected to the upper end of the bottom plate, and the first vertical plate is far away from the lifting device. One end is slidably connected with a second vertical plate, the same horizontal plate is fixedly connected with the upper end of the second vertical plate and the lifting device, the upper end of the horizontal plate is fixedly connected with a box body, and the inner wall of the rear end of the box body is fixedly connected There are two placing blocks, the same circuit board is placed on the upper ends of the two placing blocks, a positioning device is provided in the box body, a spraying device is fixedly connected to the upper end of the box body, and a spraying device is fixedly connected to the upper end of the bottom plate. There is a recovery device, the inner wall of the front end of the box body is provided with a first opening, and the inner wall of the first opening is rotatably connected with a cover plate. The advantages are: the invention has accurate positioning, is suitable for users of different heights, and can collect used etching liquid to protect the laboratory environment.

Description

technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a positioning device for etching electronic circuit boards. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. Etching is the technique of removing material using chemical reaction or physical impact. Etching techniques can be classified into wet etching and dry etching. Usually referred to as etching, also known as photochemical etching, refers to removing the protective film of the area to be etched after exposure plate making and development, and contacting chemical solution during etching to achieve the effect of dissolution and corrosion, forming concave-c...

Problems solved by technology

[0003] Schools often need to use circuit boards for related experiments, and often need to etch the circuit boards, but most of the current circuit boards are not positioned accurately during processing and are easy to shake, and the height of the relevant processing equipment is fixed, which is not suitable for use of different heights Or, it is easy to stand up and inconvenient to operate, and lacks the relevant waste liquid recovery device, which is easy to pollute the laboratory environment
