This book was released on 2017 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in aerospace technologies demand new ways to package electronics for high temperature and harsh environments. One packaging method of interest in academia and industry is Low Temperature Co-fired Ceramic (LTCC). LTCC is a multi-layer design and packaging system that can embed passive components and thermal management structures within a substrate. This thesis compiles research done to evaluate LTCC as a high-performance electronic packaging technique by determining the performance of embedded passives and thermal management structures at temperatures from -55°C to 225°C. The passive structures and thermal management structures are evaluated using theoretical calculations, simulations, and measurements of fabricated devices.

This book was released on 2017 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this dissertation research is to develop a low temperature co-fired ceramic (LTCC) interposer-based module-level 3-D wire bondless stacked power module. As part of the dissertation work, the 3-D wire bondless stack is designed, simulated, fabricated and characterized. The 3-D wire bondless stack is realized with two stand-alone power modules in a half-bridge configuration. Each stand-alone power module consists of two 1200 V 25 A silicon insulated-gate bipolar transistor (IGBT) devices in parallel and two 1200 V 20 A Schottky barrier diodes (SBD) in an antiparallel configuration. A novel interconnection scheme with conductive clamps and a spring loaded LTCC interposer is introduced to establish electrical connection between the stand-alone power modules to connect them in series to realize a half-bridge stack. Process development to fabricate the LTCC based 3-D stack is performed. In traditional power modules, wire bonds are used as a top side interconnections that introduce additional parasitic inductance in the current conduction path and prone to failure mechanism under high thermomechanical stresses. The loop inductance of the proposed 3-D half-bridge module exhibits 71% lower parasitic inductance compared to a wire bonded module. The 3-D stack exhibits better switching performance compared to the wire bonded counterpart. The measurement results for the 3-D stack shows 30% decrease in current overshoot at turn-on and 43% voltage overshoot at turn-off compared to the wire bonded module. Through measurements, it has been shown that the conducted noise reduces by 20 dB in the frequency range 20-30 MHz for the 3-D stack compared to the wire bonded counterpart. A simulation methodology using co-simulation techniques using ANSYS EM software tools is developed to predict EMI of a power module. Hardware verification of the proposed simulation methodology is performed to validate the co-simulation technique. The correlation coefficient between the measurement and simulation is found to be 0.73. It is shown that 53% of the variability in the simulation can be explained by the simulated result. Moreover, the simulated and measured amplitudes of the EMI spectrum closely match with each other with some variations due to round-off errors due to the FFT conversion.

This book was released on 2019 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Low Temperature Cofired Ceramic (LTCC) is a material system that is ideal for integrated microelectronic packaging technology, because of its rapid prototyping and easy integration of passive components such as resistors, capacitors, and conductors. LTCC's electrical properties makes it especially suitable for high frequency applications such as magnetrons. Recently, there has been an increased demand for greater power capacities which is resolved by phase locking multiple low power (inexpensive) magnetrons together to achieve the same power as one high power (expensive) magnetron. The Vacuum Electron Devices (VED) and Ceramic Micro Electrical Mechanical Systems (CMEMS) labs at Boise State University have designed a new field emission cathode for the L3 Technologies industrial magnetron that will precisely inject electrons into the system. This controllable electron injection, has been shown by simulation to decrease startup times, increase efficiency, and even allow for active phase control during oscillation. In this research, new LTCC manufacturing techniques were developed in order to fabricate the newly designed cathode. Two different cathode wrapping techniques were compared and the layer by group technique was faster, more easily aligned, and had a shorter learning curve. Two different via filling techniques were compared and the flat fill technique was slightly slower but, more repeatable and was less likely to cause electrical shorting. Two different facet plate manufacturing techniques were compared and the mill technique was more precise and extremely repeatable. Four different stands were compared and the square post stand had the best circularity and linearity measurements of the fired cathode. Finally, the spiral embedded stripline line was prototyped and an elementary version was assembled which matched simulations."--Boise State University ScholarWorks.
