Definitions
- keyboards In the production of keyboards, three different manufacturing processes are known in principle.
- the most widespread keyboard arrangement is a sheet metal frame which is equipped with key modules and which is then mounted on a circuit board.
- the problem arises that in the case of keyboards with many key modules and decoupling diodes, a large number of soldering pins have to be inserted into the printed circuit board. This goes so far that with a keyboard with approx. 70 keys and 70 decoupling diodes as well as a few LEDs for display, more than 150 pins have to be inserted into the circuit board at the same time.
- Fig. 3 is a view of the keyboard from below with printed conductor tracks.
- This keyboard injection part can then be further processed in the automatic assembly, with the movable contact parts, the return spring and the keyboard plunger 19 being inserted and finally the cover of the switch
- the matrix required for the keyboard is also populated by equipping the keyboard body 11, the separate printed circuit board being saved.
- the advantage of automation can be further exploited in that the connection of the fixed contact parts or other connections such as LED connections or decoupling diodes to the conductor track is made directly by conductive adhesive. As a result, the entire keyboard no longer has to be passed over a solder bath, i.e. H. the assembly machine that assembles the key can also be used as a keyboard machine.
- the present invention then also makes it possible, in contrast to the problems in the production of membrane keys, to continue to use connection techniques previously customary in the keyboard itself. In this way, connector strips or LEDs, decoupling diodes, etc. can also be installed.
