Problems solved by technology

PCB carries the core technical secrets of electronic companies. Therefore, once the PCB circuit is leaked, it will cause the leakage of the company's research and development results, which will bring major losses to the company and allow competitors to take advantage of it. Therefore, an anti-plagiarism PCB is developed to protect the company's technology. Not being leaked is an urgent need for enterprises

Embodiment

[0032] Embodiment: an anti-plagiarism shielding type PCB printing process, comprising the following steps:

[0033] S1. Data production: the data production includes back soldering data production and solder resist data production,

[0034] Among them, the production of back welding data: copy the text graphics on the back welding graphics during engineering CAM data processing, and then hollow out the text shapes on the corresponding back welding graphics according to the text graphics, and finally integrate the back welding graphics and text graphics into one graphic On, form the back soldering data graphic;

[0035] Production of solder mask data: when engineering CAM software is used to produce solder mask data, set the oil block under the position where the previous printing is required;

[0036] S2. Screen production: the screen making station makes back-welding screens and solder-resisting screens according to the back-welding data and the solder-resisting data;

[00...

Abstract

The invention discloses an anti-plagiarism shielding type PCB printing process. The process comprises the following steps of: S1, data production; S2, screen printing plate production; S3, rough shapecutting; S4, line pretreatment; S5, silk screen line printing; S6, line UV curing; S7, etching and deinking; S8, solder resist pretreatment; S9, silk screen solder resist printing; S10, back character printing: a back-welding screen printing plate is adopted to perform back character printing, and an ultraviolet curing mode is adopted to perform back-welding UV curing; S11, front character printing; and S12, electrical inspection and visual inspection. With the anti-plagiarism shielding type PCB printing process adopted, a cumbersome PCB printing process flow is improved, the printed surfaceof a PCB is smooth and flat, the defect rate of the PCB is lowered, printing efficiency is high, product quality is improved, and the production cost of enterprises is saved. A PCB produced by the process of the invention has an anti-plagiarism function, the lines of the PCB can be protected from leaking, and the technical secrets of the enterprises can be protected.

Description

technical field [0001] The invention belongs to a manufacturing process of a printed circuit board, in particular to an anti-plagiarism shielding PCB printing process. Background technique [0002] Printed circuit board is a bridge that carries electronic components and connects circuits. As the "mother of electronic products", it is widely used in communication electronics, consumer electronics, computers, automotive electronics, industrial control, medical equipment, national defense and aerospace and other fields. It is an indispensable electronic component in modern electronic information products. The development level of the printed circuit board industry can reflect the development speed and technical level of a country or region's electronic information industry to a certain extent. In the current environment of accelerated evolution of cloud technology, 5G network construction, big data, artificial intelligence, sharing economy, industry 4.0, and the Internet of Thi...
