Problems solved by technology

At present, domestic ultra-long microwave high-frequency circuit boards adopt segmental drilling in the processing process, but this method is easy to cause aperture displacement, affects product quality and is inefficient
In addition, the current treatment of the hole wall in the production process is to use sodium salt solution and plasma for treatment, but this not only reduces the storage stability of the circuit board, but also produces a large amount of waste liquid and waste gas, which is not conducive to the requirements of "clean production"

Abstract

The invention discloses a method for manufacturing an ultra-long microwave high-frequency circuit board, comprising the following steps: (1) manufacturing a light potting template; (2) shearing to form an ultra-long combination board, and drilling holes on the ultra-long combination board; (3) metallizing the walls of the holes; (4) making patterns on the ultra-long combination board; (5) electroplating and etching the ultra-long combination board; and (6) forming the ultra-long combination board into the ultra-long microwave high-frequency circuit board. The method for manufacturing the ultra-long microwave high-frequency circuit board has high precision, and the ultra-long microwave high-frequency circuit board manufactured with the method has stable performance and can effectively improve the product quality and the work efficiency.

Description

technical field [0001] The invention relates to a manufacturing method of an ultra-long microwave high-frequency circuit board. Background technique [0002] With the rapid development of electronic informatization, especially the promotion of 3G network, the application of ultra-long microwave high-frequency circuit boards is becoming more and more extensive. At present, domestic ultra-long microwave high-frequency circuit boards adopt segmental drilling in the processing process, but this method is easy to cause aperture displacement, affects product quality and is inefficient. In addition, the current treatment of the hole wall in the production process is to use sodium salt solution and plasma for treatment, but this not only reduces the storage stability of the circuit board, but also produces a large amount of waste liquid and waste gas, which is not conducive to the requirements of "clean production" . Contents of the invention [0003] The invention provides a me...
