ABSTRACT:
An enclosed electrical circuit and method for manufacturing the electrical circuit are provided. Initially a flexible substrate is formed with a plurality of electrical circuits. By way of example, each circuit can contain a conductive trace, a battery and a die, all in electrical communication. During the manufacturing process, a barrier is placed on the substrate and a curable encapsulant is poured into a cavity formed by the barrier and the substrate to encapsulate each circuit. The barrier can be formed as a compartmentalized dam having a separate cavity for each circuit, as a perimeter dam having a single cavity, or as a spacer sheet having a separate cavity for each circuit formed by a pattern of cut outs. Following the encapsulation step, the electrical circuits can be singulated into separate encapsulated circuits.
