Description

Vertical diversion type thin plate chemical treatment device

technical field

The utility model relates to a device, in particular to a vertical diversion type thin plate chemical treatment device.

Background technique

With the advent of the information age, the printed circuit board (PCB) is an important component of various electronic products, and plays a key role in the precision design of precision electronic products in terms of function and any peripheral parts. The existing manufacturing process of printed circuit boards includes: surface treatment, lamination, exposure, developing, washing, etching, stripping and other treatments. That is to say, it includes processes such as chemical treatment and cleaning. Traditionally, most of the above-mentioned chemical treatment processes for printed circuit boards are based on horizontal equipment.

However, with the development of thinner printed circuit boards to meet the needs of today's high-tech products, the thickness of printed circuit boards is getting thinner and thinner. Common specifications are about 0.06mm to 1.2mm, and the thickness of copper skin is 18mm. ~70μm. Furthermore, the circuits of thin sheets are getting finer and more delicate, and they are also very easy to be damaged. Therefore, the traditional horizontal equipment used for chemical treatment, whether it is the way of conveying or spraying chemical solutions (such as developer solution) on thin plates, can no longer achieve the expected processing quality, and even easily damages the thin plates.

For the chemical treatment and cleaning process of the thin plate, some operators have tried to change it to the vertical equipment shown in Figure 1 for processing, that is, the thin plate 13 is clamped on the rack (Rack) 14, and moved to it by a crane. Each designated treatment tank 11 performs cleaning or chemical treatment. However, although the chemical solution 12 in the treatment tank 11 is circulating, its fluidity is still not enough, and in order to make the chemical solution 12 in the tank have higher fluidity, many methods are used, such as utilizing a blower to blow the Air is input into the bottom of the treatment tank 11 so that the solution can be affected by air bubbles, or a water injection pipe is provided in the treatment tank 11 to help the fluidity of the solution, so as to increase the surface exchange and reaction speed of the thin plate 13.

Yet in above-mentioned prior art (Prior Art), although it has certain effect for helping chemical solution to flow, but along with the quality requirement of thin plates such as printed circuit board, aluminum plate material more and more higher, and for the processing tank 11 The volume is required to be smaller and smaller to achieve the purpose of not occupying space; therefore, the chemical treatment tanks currently used still have their imperfections.

In view of this, the creator of this paper is making persistent efforts, using his previous experience in electroplating and other wet processes, to continuously research and improve, in order to provide PCB or aluminum plates and other thin plates with chemical treatment and cleaning processes such as development, etching, and film removal. A better way.
