Description

PCB centering and positioning device

Technical Field

The utility model relates to the technical field of PCB production, in particular to a PCB centering and positioning device.

Background

At present, in the production process of mutual hole connection of double-sided and multilayer printed circuit boards in China, most manufacturers adopt the following steps: the conductor material is plated on the hole wall by a lead wire, a rivet or an electroless plating method (electroless copper plating method, blackening method), and then directly plated. Such a method is advantageous and disadvantageous and also effective, but is costly to manufacture and presents environmental concerns. The generation of the through hole technology forms effective interconnection and overcomes the defects of the traditional mode. The conductive silver paste, carbon paste or copper paste and other printing materials are permeated into the prefabricated holes through screen printing, so that the conductive printing materials with the injection body or rivet type structure are filled in the holes, and the conductive printing materials are solidified to form the interconnection via holes. Compared with other interconnecting hole connection methods, the method has the advantages of simple process, short period, suitability for environment-friendly production and great competitiveness in cost. Although the development time of the technology is longer, the enterprises applied on a large scale before are not many, and along with the strong market competition, the electronic products are light, thin, short and small and are subject to pressure in various aspects such as cost, manpower, environmental protection and the like. Such screen printing techniques using silver, copper or carbon vias have been increasingly adopted and applied in the electronics field.

At present, a semi-automatic printing machine is generally adopted for through hole equipment, however, after silver paste is poured into a circuit board, the surface of the circuit board is not dried, and only an ineffective area which is about a few millimeters wide at the edge of a plate can be contacted, and when people receive materials, a printing area is easily contacted, so that the plate is polluted. Therefore, in order to improve the yield, the industry usually places the circuit board in the letter box and then fills silver paste. However, the manual work will take the circuit board and place the working strength big in the mouth word frame, be difficult to the centering, can cause the circuit board to damage when appearing the deviation, influence the yields, be unfavorable for batch production.
