LTCC Breakdown Voltage Investigation

Abstract High voltage properties of the LTCC (Low Temperature Co-Fired Ceramics) cofired ceramic tape are presented. Chauvin Arnoux C.A. 6555 insulation tester is used to measure the leakage current and the resistance. Measurement is possible up to 15 kV. The DuPont 951 test structures are manufactured. The electrodes are fabricated of Ag (DP 6142) and PdAg (DP 6146) pastes. The leakage current dependence upon the temperature up to 320°C is measured. The ceramics properties depend on the temperature, especially beyond 200°C. Moreover, the current characteristics as a function of electrical field are presented and the breakdown voltage is determined.
