Abstract

The present paper reports on the micro thick film growth problems on Low temperature co-fired ceramic technology. The focused interconnection technique is isothermal solidification to provide, power supply connection for micro heater. In this isothermal solidification process, the diffused amount of material and formation of intermetallic phase molecules depends on the surface growth , grain size of the micro thick films, resultant contact surface area with inter layer, temperature and density gradient between the base layer to solder layer. Surface growths of the silver thick film on LTCC substrate is studied with the help of SEM.

Abstract

Reliability of electrical connections of a Low Temperature Co-fired Ceramics (LTCC) device is always a challenge. LTCC base plates are fabricated, over which a device or a sensor can be placed. Vias punched at the corners allows the provision for the electrical connection to the sensor. Conductive PdAg lines printed over the surface can be used to join the sensor part with the base plate using brazing technique. Cost of fabrication is lowered by punching the cavities using a zig fixture.
