At present, many related products will use plasma cleaning machine for surface treatment. Aerospace connector is one of them. Chengfeng Zhizao has accumulated rich experience in this area.
        High-precision fields such as aviation and aerospace generally have higher product requirements, and plasma cleaners are required to perform surface treatment on connectors and some metal parts. Next, take the connector as an example to introduce the related processing technology of plasma cleaning connector in aviation and other fields.

Plasma cleaning connector
        Generally, the connectors used in aviation and other fields are relatively small, mainly including fluorosilicone rubber FVMQ connectors, thermoplastic polyester PBT connectors, polyphenylene sulfide plastic PPS connectors, polyetheramide PEI connectors, etc., for bonding and printing The requirement of plasma cleaning machine is high. The original wiping and special glue bonding are replaced by plasma cleaning machine pretreatment, which can not only meet the environmental protection requirements, but also improve the reliability and consistency of the treatment.
        Using a plasma cleaner to clean the connector base can remove silicone oil or release agent from the surface of the connector, improve the surface cleanliness of the product, and also improve the surface energy of the base, and improve the adhesion and reliability of the silk-screened characters. It can improve the printing and bonding effect of the connector. The change in the angle of the water droplets before and after the connector product base was processed by the plasma cleaner. The angle of the connector base was changed from 121 degrees to 50.8 degrees, and the aviation connector base was changed from 103.99 degrees to 53.6 degrees.
        For the plasma surface treatment of aerospace products, there are two points worth noting:
        1. The hydrophilic groups produced during the activation process of the plasma cleaner are easy to disappear with time. Therefore, after the plasma cleaner is processed, the subsequent treatment shall be carried out as soon as possible;
        2. The process parameters used in plasma cleaning machine processing will be selected according to the different materials. In terms of parameter control, it is also an inspection of the equipment manufacturer's ability.
