<p>A method of making electrical devices, and the electrical devices made thereby, comprising the steps of: stamping from a sheet of metal a pattern of conductors configured to connect circuit components together in a relationship which forms a useful product, such as a watch, with the terminals of each of said circuit components being adjacent and connectable to appropriate terminating means formed in said pattern of conductors when said circuit components have predetermined positions adjacent said pattern of conductors; encapsulating said pattern of conductors with plastic having cavities and apertures formed therein, the cavities each having a configuration and a location to receive one of said circuit components therein in said predetermined positions and with said terminating means extending into said cavities to terminate the terminals of said circuit components; forming at least some of said component terminals on the surface of said components in positions to bend over the terminating means when the component is inserted in a cavity to thereby make an electrical connection between the component terminals and the terminating means, and to provide a retaining housing for the components in said cavity. In some instances, the component terminals are wire-like in shape and require the forming of the terminating means in a configuration which can be crimped therearound or, alternatively, require the forming of the terminating means into a plate with a slot therein and into which slot the wire-like terminal can be inserted. Some of the apertures in the plastic encapsulation are positioned to enable the severing of portions of the lead frame conductors which support the lead frame until it is encapsulated and others of the apertures are positioned to enable the severing of various combinations of selected conductors to produce different patterns of interconnections between the circuit components and thereby to produce various electrical devices each capable of performing different functions.</p> |
