Description

Edge driving mode circuit board wet process vertical rotation swinging device Technical Field The utility model belongs to the technical field of circuit board processing, and particularly relates to a vertical rotation swinging device for a circuit board wet process in an edge driving mode. Background The process flow of circuit boards is much more complex than most products, and those skilled in the art generally refer to the processes having a relatively high degree of water association as wet processes and the processes having a relatively low degree of water association as dry processes. The wet process may be divided into a material reduction wet process, such as developing, etching, removing film, etc., to remove material from the product by wet process, an additive wet process, such as copper deposition, nickel deposition, etc., which is an electroless plating, and a plating, such as copper plating, tin-lead plating, etc., which is a plating, and a cleaning wet process, such as commercial water cleaning, DI water cleaning, etc. At present, the conventional material-reducing wet process such as developing, etching, removing film, chemical cleaning and the like mostly adopts horizontal processing, so that the water pool effect is necessarily accompanied, and the water pool effect refers to the phenomenon caused by accumulation of liquid medicine on the upper surface of the PCB when the liquid medicine such as an etchant and a developer is sprayed. This pool of water acts as a barrier to uniformity of chemical reaction, allowing the lower surface of the article to react faster than the upper surface, and the central region to react faster than the peripheral regions. At present, no matter chemical plating or electroplating is adopted in the traditional material-increasing wet process, a static processing mode is adopted, and the risk of static processing is that bubbles are easily wrapped in holes to form processing defects, particularly products with more micropores, and along with the miniaturization development of electronic products, circuit boards with micropore designs are more and more. Such defects due to bubbles in the micro-holes may in many cases lead to rejection of the entire circuit board due to a void in one hole. And the production line is longer and shorter than ten meters, and is even hundreds of meters long, so that the product is difficult to use for enterprises of research type, self-use type or small and medium-sized substitutes because the occupied area is too large. Because the traditional wet processing equipment is too huge, other problems such as high starting-up cost, inconvenient intermittent production such as large environmental pollution and problems on the health of staff and the periphery of a factory are caused, so that the three-waste treatment cost of the enterprise is increased. In addition, the update speed of the interface liquid medicine of the chemical reaction of the existing production equipment is low, so that the processing efficiency is low. Disclosure of utility model In view of this, the present utility model aims to provide a vertical rotation swinging device for a circuit board wet process in an edge driving mode, which aims to greatly reduce the size of equipment, reduce the occupied area, improve the yield, improve the processing efficiency, and reduce the environmental pollution and the cost of three wastes in enterprises.
