Electronic tracking label with a fold-over battery attachment
An electronic tracking tag that attaches a battery to the tag's circuitry by folding over a portion of the flexible PCB on top of the battery to secure it between two conductive pads. This configuration eliminates the need for a battery holder, thereby reducing weight, cost, and thickness and enabling a label containing the electronics to be fed through a printer without damaging the circuit. The battery may be attached to conductive pads using a conductive adhesive such as a conductive tape, avoiding the use of rigid or brittle tabs or epoxies that may break under the stress of going through the printer. An illustrative configuration with the electronic components, the battery, the fold-over battery attachment, and a label front and liner backing may be less than 2100 micrometers thick.
