Problems solved by technology

This process can solve the problem of low precision caused by the use of film sheets. The process is relatively simple and the production cost is low. However, there are certain deficiencies in the existing inkjet printing technology, which are mainly reflected in the poor printing effect and edge It is prone to oil accumulation, fat or shrinkage, and even ink flying, which not only affects the accuracy, but also easily leads to short circuits in the inner circuit and open circuits in the solder mask layer.

Abstract

The invention relates to a method for printing and photocuring continuous printing and equipment for printing and photocuring continuous printing. The method for printing and photocuring continuous printing comprises the steps that printing and photocuring are carried out, the plane angle position X1 of a PCB base material is fixed before printing, the PCB base material sequence number A1 is marked, the printed document position is calibrated according to the plane angle position X1 of the PCB base material, the printed document sequence number B1 is marked, and the PCB base material with thesequence number A1 is printed according to a document B1; and then the printed PCB base material is moved to the photocuring position, the document B1 is conveyed to a photocuring device, and photocuring is carried out on the PCB base material with the sequence number A1 according to the document B1 by the photocuring device. The problem that printing and photocuring cannot be synchronously carried out is solved through the method, and the problem about continuous printing is solved by fixing the position of the printed base material or correcting the printed document.

Description

technical field [0001] The invention belongs to the field of circuit board preparation, and specifically designs and photocures the technology for preparing circuit boards, and in particular relates to a method and equipment for continuous printing and photocuring. Background technique [0002] The production process of traditional PCB solder resist ink mainly includes: silk screen / spray coating / roller coating, pre-baking, exposure, development and post-baking processes. Developing and withdrawing film and other processes. This process has disadvantages such as complicated process and long production cycle, and the film needs to be used in the exposure process. Usually, the production process of the film is complicated, and the film is easily deformed by the temperature during use. At the same time, the film is used more After the number of times, it is easy to be worn out, resulting in low precision of the graphics produced, and it is difficult to achieve high-precision ci...
