ABSTRACT:
In making an electronic watch, a substrate of insulating material is provided on one or both faces with metal foil defining circuitry. An IC chip is mounted in a recess in the substrate, connected with the circuitry and covered with potting material. The substrate is then sandwiched between two synthetic plates which are connected with one another and with the substrate by pins extending through holes in the substrate.
