Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of circuit board processing, especially to a Z axis both ends drive mode's circuit board wet process vertical rotation swing device. BACKGROUND
[0002] The processing flow of circuit board is much more complicated than most products, and the industry insiders usually call the process associated with water as wet process, and the process associated with water as dry process. Wet process can be divided into subtractive wet process, additive wet process and cleaning wet process. Subtractive wet process such as developing, etching and film removal removes material from the workpiece by wet method. Additive wet process can be divided into chemical plating and electroplating. Chemical plating such as copper deposition and nickel deposition belongs to chemical plating, and electroplating copper and electroplating tin lead belong to electroplating. City water washing and DI water washing belong to cleaning wet process.
[0003] At present, the traditional subtractive wet process such as developing, etching, film removal and chemical cleaning is mostly horizontal processing, so it is accompanied by pool effect. Pool effect refers to the phenomenon that the drug water accumulates on the surface of PCB when spraying drug water such as etchant and developer. This pool becomes an obstacle to uniform chemical reaction, making the lower surface of the workpiece react faster than the upper surface, and the center area react faster than the surrounding area.
[0004] At present, whether it is chemical plating or electroplating, the traditional additive wet process adopts static processing mode. The risk of static processing is that air bubbles are easily trapped in the hole, causing processing defects, especially for products with many small holes and micro-holes. With the development of miniaturization of electronic products, circuit boards with small and micro-hole design will become more and more common. In many cases, the scrap of the entire circuit board is caused by a hole cavity.
[0005] Moreover, whether it is traditional subtractive wet process or additive wet process, the production line is relatively long, with a length of tens of meters, dozens of meters or even hundreds of meters. It is difficult for some research and development, self-use or small and medium-sized enterprises to use it because of the large floor area. Because the traditional wet process equipment is too large, it inevitably brings other problems, such as high start-up cost, inconvenience for intermittent production, environmental pollution, and problems for employees and the surrounding area, thereby increasing the cost of waste treatment for enterprises.
