Embodiment 1

[0027] A. Take 9 liters of ethanol at room temperature and place it in a bucket with a volume of about 12 liters. Then, add 1 liter of electrostatic agent containing 50% polyacetylene, 30% polyaniline, and 20% polypyrrole to the bucket. Stir while adding; after the electrostatic agent is added, the mixed solution is fully stirred for 1 minute to completely dissolve the electrostatic agent in ethanol.

[0028] B. Take a 10-mesh filter screen and completely wrap about 10,000 surface acoustic wave filters to be processed. Under the premise of not leaking the surface acoustic wave filter, make the surface acoustic wave filter in the filter screen as large as possible. Disperse; Then, place the filter screen wrapped with the surface acoustic wave filter in the destaticizing solvent obtained in step A, so that the surface acoustic wave filter in the filter screen is completely immersed in the destaticizing solvent, soak For 1 minute, the polymer conductive material in the static rem...

Abstract

The invention relates to a destaticizing adsorption method, which solves the problem that the existing destaticizing mode cannot completely eliminate static electricity generated in the production, transportation and use processes of a surface acoustic wave filter, and comprises the following steps of: A, mixing ethanol and a static electricity acting agent in a container to prepare a destaticizing solvent; B, completely wrapping the 20K surface acoustic wave filter by using a filter screen, and completely immersing the filter screen in an electrostatic eliminating solvent; C, drying the surface acoustic wave filter processed in the step B by using plasma wind; D, placing the surface acoustic wave filter processed in the step C in an anti-static bag to be stored for standby application; and E, performing anti-static adsorption condition inspection on the surface acoustic wave filter processed in the steps A-D. According to the invention, the destaticizing solvent is adopted, so that the surface of the surface acoustic wave filter is coated with a polymer conductive layer, a lasting antistatic effect is achieved in the subsequent technological process, and the problem of electrostatic adsorption of the surface acoustic wave filter is thoroughly solved.

Description

technical field [0001] The invention relates to a method for eliminating electrostatic adsorption, in particular to a method for eliminating electrostatic adsorption of a surface acoustic wave filter. Background technique [0002] The fifth generation mobile communication system (5G) will promote the comprehensive upgrade of the radio frequency system of mobile communication terminals. In order to enable mobile phone communication to obtain higher rate and new frequency band communication functions, it is necessary to increase the number of surface acoustic wave filters in communication equipment, which will enable surface acoustic wave filter manufacturers to obtain greater benefits. However, since the surface acoustic wave filter itself is an electronic component that is relatively easy to generate static electricity, losses due to static electricity always occur during production, transportation and use. For example, in the automatic mounting process of the surface acous...
