Membrane is made up of flexible printed circuit, adhesive, so we must pay attention to it when clean and keep it.
- Clean the surface to which the membrane switch is to be applied (flat, rust-free, oil-free, dust-free surface).
- Compare the size (the membrane switch to the place to be compared to the size of the location is right).
- Then peel the bottom of the membrane switch from the edge of centrifugal paper around 10mm.
- put the membrane switch to the corresponding position to affix a part, then slowly tear off the remaining centrifugal paper (in the case of not more than 15 degrees angle), followed by paste to the corresponding location.
- Tear off the reverse side of the process if the membrane of the membrane switch membrane needs to be placed first, should be placed upside down to prevent sticking to other objects affect the paste.
- Note: Paste can not repeat the operation, to be completed in one go, tear angle can not exceed 15 degrees; try touch, be sure to flat on the desktop and then press, can not take in the hand vacated, otherwise they will Affect the life of membrane switch.
- Membrane switch and film switch between the bubble film is pressed to reduce the pressure to prevent failure, should be retained.
- Membrane switch is covered with transparent membrane is to protect the membrane switch display window, do not easily tear.
- Remove some of the membrane switch, it should be in accordance with the original beam is good, but definitely not too tight bundle.
- There are hand, a large number of film surface paste, membrane switch, need to pack vertical, to prevent a long time to press the key failure.
- Membrane switch to protect the outlet, outlet can not be placed down.
- There is a display window membrane switch, in the take, when the material must be to prevent the bending force, will leave a crease.
- Membrane switch stored in room temperature, should be dust-proof, moisture-proof treatment, the surrounding air is not acidic, alkaline or other corrosive gases.
