A method of manufacturing a PCB through utilization of 3D printing technology

Abstract

The invention provides a method of manufacturing a PCB through utilization of 3D printing technology. The method comprises the following steps: 1, a substrate is printed; 2, lines are printed; 3, the substrate is modified; 4, polishing, grinding and shaping are carried out; and 5, characters are printed. According to the method, lines are manufactured on the existing substrate, so that a local machine only needs to make the substrate and shape the substrate without artificial intervention in a production process; the manufacturing process can be automatically completed by a computer; manpower is saved; no waste water, exhaust gases, etc. will be generated in production; the production is environment-friendly and safe; production factories do not need to pay great amounts of water and electricity charges and expensive water treatment costs, so that production costs are effectively reduced and production materials are saved.

Description

technical field [0001] The invention relates to the technical field of cloth production, processing and manufacturing, in particular to a method for making a PCB board by using 3D printing technology. Background technique [0002] At present, the production and processing of PCB boards mainly include traditional production methods and relatively advanced 3D printing production. As far as traditional production methods of PCB are concerned, there are major technical problems. For example, the main disadvantage is that more chemicals are used during production, and the waste gas generated And waste water and residues will cause relatively serious pollution to the environment, and there are many production processes, long production time, and low automation, which will increase the incidental costs of the factory a lot. Normally, no pollution is much higher than that of a factory, and the sewage produced needs to be treated, etc., and the price of production equipment is high, ...

[0002] At present, the production and processing of PCB boards mainly include traditional production methods and relatively advanced 3D printing production. As far as traditional production methods of PCB are concerned, there are major technical problems. For example, the main disadvantage is that more chemicals are used during production, and the waste gas generated And waste water and residues will cause relatively serious pollution to the environment, and there are many production processes, long production time, and low automation, which will increase the incidental costs of the factory a lot. Normally, no pollution is much higher than that of a factory, and the sewage produced needs to be treated, etc., and the price of production equipment is high, and the power consumption is relatively large, which will also indirectly pollute the environment. It does not conform to the national concept of energy conservation and environmental protection.

[0003] Compared with the traditional PCB board production and processing technology, 3D printing technology has made great progress. However, the existing 3D printed PCB board production method has many shortcomings, and it cannot completely replace the existing traditionally produced PCB board, and the cost is relatively high. , because generally conductive line conductors are relatively expensive conductive inks, etc., the quality and stability are not as good as traditionally produced PCB boards, and the installation and welding of electronic components cannot be completely the same as traditionally produced PCB boards. The existing 3D printing The production capacity of technical mass production of PCB boards cannot meet the requirements of the factory and needs to be further improved
