Presentation Summary

A range of novel ink developments are described:
1) To manage the fluctuations and uncertainty in the silver price while trying to reduce the cost of devices and components using printed silver conductors, various solutions are investigated; these range from simply reducing the Ag content in the paste to formulating unique Ag-alloy compositions. This approach can provide a cost saving of up to 20%. In addition, faster processing using Photonic sintering is explored and a significant performance/resistivity improvement is demonstrated.
2) To enable 3-dimensional capacitive switch circuitry, a specially designed elastic formable silver composition has been developed. Some benefits are outlined particularly in automotive applications. Furthermore, this technology can provide circuit and product designers more freedom to bring creative solutions to their products.
3) An improved carbon composition with extremely high Positive Temperature Coefficient (PTC) characteristic is used to fabricate flexible heater circuits with self-limiting temperature properties. A couple of applications are identified and the benefits of using PTC carbon are described.
