Abstract

The invention discloses a method for producing a PCB (printed circuit board) from calixarene. The method comprises the steps as follows: a) calixarene and an organic solvent are added to a container provided with a stirring device at the normal temperature and under the normal pressure and stirred continuously, and a printing liquid can be obtained; b) a substrate is drilled, cleaned and placed on a screen printing machine; c) the printing liquid is added to the screen printing machine and applied to the substrate; d) the substrate is placed in an environment at the normal temperature and under the normal pressure to be aired naturally for later use; e) the substrate is placed on a screen printing table of another screen printing machine, and liquid copper slurry is added and applied to a printing liquid layer; f) the substrate is placed in a baking oven to be baked and then naturally cooled to the room temperature, and the PCB can be obtained. The method for producing the PCB from calixarene is high in environment friendliness, the adhesion of copper particles on the substrate can be increased, oxidation of conductive circuits on the substrate can be prevented effectively, and impedance of the conductive circuits can be reduced.

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 protection 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 clea...
