Several MEMS applications including microturbines, engines, and micro heat exchangers demand ultra high pressure and temperature withstanding microchannels. This paper focuses on design and analysis of such microchannels fabricated using LTCC technology. Extensive FE simulations and analysis are carried out to characterize various design parameters enabling(More)
Today's high functionality electronic circuits require faster interconnection speed, better thermal conductivity and the good mechanical properties for reliability. These requirements calls for enhanced properties of the present solder materials. Appropriate reinforcements in the existing solder material will help in achieving much improved electrical,(More)
This paper reports the Simulation, Design, fabrication and preliminary testing results of a single channel, open cycle miniature Joule-Thomson (JT) refrigerator. Miniaturization of the refrigerator is aimed at providing an alternative that would suffice both the requirements of milli watt cooling as well as high portability owing to its light weight. The(More)
This paper presents structural, morphological and electrical characterization of the in-house developed ruthenium oxide based thick film resistor pastes for buried heater applications in LTCC. The basic electrical characterization of heater shows that the designed test heater achieved temperature up to 238°C. The required power to raise the(More)
LTCC is a known suitable platform for microfluidic systems. We have developed actuation-less non-return valve for gases and liquids, which is based upon the inlet and reverse pressure. This work compares three different designs of such valves. In these designs, top lid and bottom cavity layer together forms micro fluidic channel, through which fluid or gas(More)
