Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
In a process of making an electronic watch, the combination of steps comprising: providing a substrate of insulating material with at least one through hole, providing a conductive circuit on at least one face of said substrate to form a circuit board, mounting an integrated circuit chip on one face of said circuit board, electrically connecting the integrated circuit of said chip with the circuit of said circuit board, covering said chip and its connection to said circuit board with an insulating potting material, separately forming two plates of synthetic resin material, sandwiching said circuit board between said plates and connecting said plates and circuit board through said through hole to form a unitary assembly.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
28 words
A process according to claim 1 in which a recess is formed on one side of said substrate to receive said chip which is mounted in said recess.
Claim 4
Dependent Claim
65 words
A process according to claim 1, in which said substrate is provided with a plurality of said through holes near its periphery and in which one of said plates is formed with a corresponding plurality of pins which extend through said holes in said substrate and aligned holes in the other of said plates and are headed to connect said plates and said substrate therebetween.
Claim 5
Dependent Claim
