The metal dome is made of metal material. The initial state of the dome is convex upwards, and when the operator presses it hard, it is concave downwards. This kind of metal dome is called a metal dome switch by many people. Now the metal dome is widely used, although the touch screen replaces the dome switch a little bit, but the dome switch is more stable in use. Metal domes are mainly used in: for push button switches, membrane switches, keyboards, metal dome switches and shrapnel.
The process of cleaning the metal dome during the production process is very critical, and it will even affect the quality of the metal dome. Why do you say that? Because if the metal dome is not cleaned, it will affect the conduction of the circuit board, which is a functional problem, and the dome cannot be used normally.
First of all, I will take you to understand the cleaning process of the metal dome. The cleaning of the dome mainly relies on ultrasonic waves and uses special chemical reagents for cleaning. The cleaning process takes about an hour or so. After cleaning, it needs to be dried, and it takes about an hour to dry. If not cleaned thoroughly, lamination may develop, causing rust and stains. Therefore, it is necessary to constantly observe and adjust during the cleaning process to avoid the phenomenon of stacking. After drying, the metal domes will be manually screened, and the domes that are not cleaned thoroughly will be selected to avoid affecting other domes.
