Abstract

The invention discloses a method for producing a printed circuit board by using calixarene. The method comprises the following steps of: a) adding the calixarene and an organic solvent into a container with a stirring device separately at normal pressure and temperature, and stirring the calixarene and the organic solvent continuously so as to obtain a calixarene solution; b) adding liquid copper slurry and the calixarene solution to a container with a dispersion device separately at normal pressure and temperature, performing dispersion continuously, filtering out the material so as to obtain a primary printing liquid; c) drilling and cleaning a substrate, and placing the substrate on a screen printing machine; d) applying the obtained primary printing liquid to the screen printing machine and applying the primary printing liquid to the substrate to form a printing liquid layer; and e) baking the obtained substrate in a baking oven and then naturally cooling the substrate so as to obtain the printed circuit board. The method for producing the printed circuit board by using calixarene is friendly to environment, can improve the adhesive force of copper particles on the substrate, and reduces the impedance of a conductive line.

Description

technical field [0001] The invention relates to the field of processing printed circuit boards, in particular to a method for manufacturing printed circuit boards using calixarene, which has good environmental performance and excellent quality stability. Background technique [0002] With the continuous development of the economy, printed circuit boards are increasingly widely used in household appliances, industrial electronics and other industries. Because the printed circuit board has the advantages of greatly reducing the processing cost of electronic products, strong industrial reproducibility, high degree of automation and high production efficiency, it is favored by the majority of electrical and electronic industry manufacturers. However, there are two major technical deficiencies in the existing printed circuit board production process. First, traditional printed circuit boards are usually processed by a reduction method, which is mainly composed of cleaning, lamin...
