The membrane switch, the surface stick, also known as the light touch keyboard, is a unitary sealing structure composed of a flat multi-layer, which is a light collecting, machine and electric integration that seals the key switch, the panel, the mark, the symbol display and the lining plate together. A new type of electronic component is a fundamental change in the appearance of electronic products. It can replace the buttons of conventional discrete components and perform the tasks of the operating system more reliably. Let us understand what the precautions of the membrane switch are and what it is. Cleaning steps:

(1) Notes

1. The bubble film lined between the membrane switch and the membrane switch is used to reduce pressure and prevent failure, and should be retained.

2. The transparent film on the front and back of the membrane switch is the display window for protecting the membrane switch. Do not tear it off easily.

3. After taking out a few of the membrane switches, they should be bundled as they are, but they should not be too tight.

4. There are handles, a large number of film surface stickers, membrane switches, all need to be boxed vertically, to prevent the button from pressing for a long time.

5. The outlet of the membrane switch should be protected and should not be placed with the cable facing down.

6. The membrane switch with display window should prevent the material from bending under the condition of holding and placing, and there will be creases.

7. The membrane switch should be stored in a room at room temperature. It should be dust-proof and moisture-proof, and there is no acid, alkaline or other corrosive gas in the surrounding air.

(two) method steps

1. Clean the surface of the membrane switch to be fitted (requires that the surface to be fitted is flat, rust-free, oil-free, dust-free).

2. Compare the size (put the membrane switch to the point where you want to paste it to compare the size of the position).

3. Remove the centrifugal paper from the bottom of the membrane switch from the side by about 10 mm.

4. Then place the membrane switch in the corresponding position and stick a part, then slowly remove the remaining centrifugal paper (in the case of not exceeding 15 degrees), and then paste it to the corresponding position.

5. If the membrane switch of the reverse centrifugal paper is torn off during the pasting process, it should be placed first, and should be placed on the reverse side to prevent sticking to other objects.

6. Note: Paste can't be repeated, it needs to be done in one time, the tearing angle can't exceed 15 degrees; when trying to press the hand, it must be flat on the table and then press it, you can't take it in your hand, otherwise it will Affect the life of the membrane switch.
