Analyze the performance of china FPC circuit membrane switch
Time of issue：
The soft film between the china FPC circuit membrane switch and the film key lining is to reduce the pressure of the keys and avoid failure, and should be preserved. Therefore, the soft film of the middle layer should not be removed during production, and the bubble film should be preserved. The following are the performance buttons of the membrane switch 1. Durability: The life of china FPC circuit membrane switch is generally more than 100 million times, so how long is the life, because the function of the switch is only affected by the longitudinal elastic film; although the elastic film has a Millions of peristalsis, but only 0.10.3 mm (double stroke) due to the small peristalsis, 2. Good sealing performance: Because the china FPC circuit membrane switch is an integral sealing structure, the contact points of the switch are not corroded by harmful gases and are not easy to be oxidized , waterproof and dustproof, so it is more suitable for various harsh conditions.
Rich colors and elegant appearance: According to the user's design, china FPC circuit membrane switch can be prominent in color and pattern scheme, and the decorative effect shows the comprehensive characteristics of material beauty, decoration beauty and craftsmanship. Low-cost electromechanical product support: traditional mechanical switches are even strongly supported when the device is soldered, while the china FPC circuit membrane switch is an adhesive that simply removes the backing paper, sticks to the outside of the machine, and the leads are inserted throughout the machine The circuit socket is connected to the circuit. 5. Small size, light weight and reliable structure: china FPC circuit membrane switch is an accessory that can be installed on the membrane keyboard according to the program.
The china FPC circuit membrane switch installation and use steps: 1. The clean membrane switch should be suitable for appearance (requires smooth appearance, no rust, no oil, no dust); Compare the dimensions (place the film switch to see if the dimensions are in the correct position);. Peel the centrifuge paper about 10 mm from the bottom of the membrane switch; Then put the china FPC circuit membrane switch in the proper position and paste a part, then gradually tear off the remaining centrifugal paper (the angle should not exceed 15 degrees), and then paste the appropriate position in turn. 5. During the bonding process, if the back of the centrifugal paper needs to be removed from the membrane switch, it should be put back first to prevent the adhesive from sticking to other objects; Note: The paste cannot be repeated, it needs to be done at one time; the tear angle cannot exceed 15 degrees; try to press the feeling, it must be pressed flat on the table, and the pressure cannot be released in the hand, otherwise it will affect the service life of the membrane switch.
