First, remove the screw and disassemble it up and down. The soft glue under the key cap of the keyboard is the key to the feeling of knocking. The core of the keyboard: matrix and control panel. Finally, we found the cause: the matrix circuit was severely corroded. Found traces of coke, determine the culprit is coke corrosion.
2. Solution process
The copper foil is carefully attached to the original circuit. Cut the copper foil into strips, cover and paste on the corroded circuit. Because the matrix circuit is very close to each other, if you are not careful, it is easy to cause multiple short circuits, so that the keyboard does not work normally. Therefore, we should lay a bottom with adhesive tape on the plastic circuit, and then stick the copper foil. After walking a strip of copper foil, lay a layer of adhesive tape. Different road sections and different layers will not be too close to cause short circuit. After covering and pasting, test again with the universal meter, and the normal path will announce the resurrection is completed. Re install the keyboard, and the familiar tapping feel comes back to you again.
