Abstract

Using sheet battery material as a circuit board substrate eliminates the weight and bulk of batteries as a separate circuit component and also eliminates the weight and bulk of fiberglass substrate or flex substrate as printed circuit materials. Insets with wiring built in can give vertical wiring between two or more circuit layers and can support electronic components which have leads connecting wiring on more than one layer of a printed circuit. Connector clips inserted when the connector pins are polarized target connection to power and to ground components of one or more layers of sheet battery. Using these connections between battery substrate components of the structure allows a single power source as A-C or solar to recharge all battery substrate in the electronic component. The effect of application of these discoveries is to reduce the size and mass of the circuit and thus reduce the size and weight of electronic devices from hearing aids and flash lights to portable computers, from video cameras to mini and portable television sets and radios.
