Regions located directly below the entry keys data is internally laminated with rigid material to increase the reliability of said keys and improve the reaction to touch.
  • the devices of the kind described above have the particular advantage of being both flexible and thin. Their main drawback, however, is in the fact that some of the components which constitute them are very fragile. This is true in particular for integrated circuits with microprocessors which include, conventionally, a silicon wafer in which the various electronic components necessary for the performance of the function (s) electronics sought. These silicon wafers are coated in a protective layer usually made of glass.
  • a device like this mentioned above constitutes, for example, an electronic timepiece, it includes furthermore a quartz resonator element encapsulated in a ceramic case or glass.
