Embodiment Construction

[0046] In order to facilitate the understanding of the present invention, the technical solution of the present invention will be specifically introduced below in conjunction with examples.

[0047] The main raw materials adopted in the manufacturing process of the present invention are as shown in Table 1, and the reagents and raw materials used in the experimental process are relatively common experimental reagents.

[0048] Table 1 Main experimental reagents and raw materials

[0049]

[0050] The whole manufacturing process is carried out under normal temperature and pressure, and its main process steps are:

[0051] a. to clean

[0052] The cleanliness of the polyimide surface directly affects the performance of the final composite film. Therefore, before starting the reaction, the polyimide film was cleaned with a large amount of absolute ethanol and acetone solution.

[0053] b. Hydrolysis reaction

[0054] Prepare 100 ml of KOH solution and set its concentration...

Abstract

A method for manufacturing a flexible microwave filter, comprising the following steps: (1) using a computer to simulate the design of the flexible microwave filter to obtain theoretical structural size parameters of the flexible microwave filter; (2) using a normal temperature wet process to convert the steps ( 1) The flexible microwave filter whose structural design has been completed is prepared; (3) The flexible bandpass filter obtained in step (2) is tested for electrical performance and / or mechanical performance. If the test result deviates from the expected value, Then adjust the parameters, return to step (1) and / or (2), and re-manufacture the flexible microwave filter; if the test results meet the expected value, then fix the parameters in steps (1) and (2) to perform flexible microwave filtering device mass production. The invention greatly improves the efficiency of researching the manufacturing process parameters of the flexible microwave filter, and only needs to complete the trial production of one sample to obtain the best process parameters, which greatly reduces the labor cost of scientific research personnel.

Description

technical field [0001] The invention relates to a manufacturing method of a flexible microwave filter. Background technique [0002] Due to the advantages of flexible electronic devices such as bendability and light weight compared with traditional rigid electronic devices, they have attracted more and more attention from scholars. Usually, flexible electronics refers to a complete flexible system. As one of the important components of flexible systems, flexible filters have important research significance and value. In practical applications, flexible filters usually need to adapt to different occasions, and only some existing studies on electrical and mechanical properties cannot fully meet the actual needs. A filter is a device that only allows waves of a specific frequency band to pass through and blocks other frequency bands that do not require signal transmission. Compared with rigid filters, flexible filters usually have the advantages of small size, conformability...
