Abstract
Packaging for electronic components includes provisions to short selected electrodes of the components together. A plastic base portion with a plurality of component receiving cavities carries a flexible, carbonized shorting element which extends between cavities. The cavities include a recess which is adjacent to the shorting element. Components can be inserted into respective cavities, and some of the electrodes will contact the shorting element. Other electrodes will extend into the recess and not be shorted.
Claims20
An apparatus comprising:
- a multi-electrode electrochemical gas sensor comprising electrodes;
- a tray, wherein the tray comprises a plurality of moldable pockets each configured to removably hold the sensor, wherein each moldable pocket includes a recessed surface;
- a shorting element positioned on the tray, wherein the shorting element comprises a conductive foam;
- wherein the sensor is positioned and removably held within one of the moldable pockets of the tray;
- wherein the multi-electrode electrochemical gas sensor is positioned in contact with the conductive foam;
- wherein the shorting element is electrically connected to short selected electrodes to one another while the gas sensor is removably held in the tray, but wherein the selected electrodes are asynchronously unshorted upon removal of the gas sensor from the tray;
- wherein the recessed surface is adjacent to the shorting element;
- wherein the shorting element is sufficiently elongated to extend through the plurality of pockets;
- and
- wherein the shorting element is received in an elongated depression formed in the tray which spans the plurality of pockets.
