Please follow the editor of customized explosion-proof keyboard products to understand the operation method of malfunction repair of keyboard keys.
1. Disassemble the keyboard. Note that when opening the keyboard, the button surface (that is, the side where we operate) must be downward and the circuit board upward, otherwise the conductive plastic on each button will fall off one after another, which will cause trouble for your repair.
2. Open the circuit board, the circuit board is generally made of soft plastic film, with button cables engraved on it, and gently scrub the circuit board with alcohol cotton with a concentration of more than 97% or medical alcohol cotton with a concentration of more than 75% . Wipe the circuit of the part of the key failure several times.
3. Check the conductive plastic on the malfunctioning part of the button. If there is a lot of dirt on the upper area, wipe it with alcohol as well. Assuming that the conductive plastic is damaged, it is recommended to replace the conductive plastic on the infrequently used buttons with the damaged part. Although this action cannot make the keyboard perform all the functions, it can at least extend the life of the frequently used buttons.
4. To remove the dirt in the inner corners of the keyboard, the tools can be brushes, small brushes, etc., but the movements should be gentle.
5. Check whether the welding module has false soldering or desoldering. If you know how to use an electric soldering iron, you can perform repair soldering work. Of course, this step is only suitable for friends who know how to use electric soldering irons. For those who do not know how to use it, please skip this step.
6. After installing the keyboard, there is one thing to note here, that is, you must wait for the alcohol to evaporate before proceeding.
The above is a customized explosion-proof keyboard products editor Jiangsu: a brief introduction to the related knowledge of the fault repair operation method of the keyboard button failure.
