It is divided into several steps, the light touch switch hand welding: temperature control at 200 c, welding time about 10 seconds wave welding: electronic touch switch temperature control at 130, welding time for about 2 seconds. Rewelding, including manual welding, should be less than 2 times. At this point, the first and second assignments should be separated for 5 minutes. When it returns to normal temperature, it will be carried out again. Continuous heating will cause external contour deformation and performance damage. The patch electronic touch switch multilayer multilayer substrate should be verified in advance. According to the type of substrate, the design and grounding of ultra thin electronic touch switch substrate may cause thermal deformation.
The electronic touch switch is suitable for the key of the electronic product. It has small shrapnel, the operation strength and the size can be controlled by the customer. The light touch switch has the stable rebound ability and has the specific service life. Cause the metal side button electronic touch switch flick is not moved first is life analysis life is not to achieve due service life or is not due to improper operation of metal shrapnel in electronic light touch switch inspection method is to take the flick out to the life testing machine to test, general electronic light When the touch switch is taken out, the eye can see that the metal shrapnel can not be pressed. The initial state of the piece is convex. If a concave line is made, it shows that the flick of the manufacturer of the light touch switch has been pressed.
