The invention discloses a preparation process of a 90-degree ultra-thin rotating twisted
waveguide, which includes the following steps: S101, pre-preparing a 90-degree rotating shape part 1 and a standard part matching the 90-degree rotating
waveguide cavity; S103, preparing for
assembly and soldered external part 2, wherein the external part 2 includes an
assembly groove and a fixing slot for matching with the 90-degree rotating external part 1; S105, interference fitting the obtained 90-degree rotating external part 1 into the obtained The shape of the second middle. By pre-preparing the 90-degree rotating outer part 1 and the outer part, the 90-degree rotating outer part 1 is dissolved with acid and alkali solution after
assembly, and the 90-degree rotating
waveguide cavity is retained, and the 90-degree rotation is realized by
electroplating,
welding and
cutting. The preparation of the ultra-thin twisted twisted waveguide not only has a simple process for
processing finished products, but also has a high
yield rate, and waste materials can be reused, which is beneficial to
environmental protection. In addition, the finished product of the 90-degree ultrathin twisted twisted waveguide through the preparation process has excellent electrical properties.
