Clustering Algorithms for Component Placement in Printed Circuit Boards
… typically have hundreds, sometimes thousands of components and even more net connections between them. This makes both manual and automated placement very time-consuming. As a way to improve placement performance, in this thesis, we constructed a custom weighted undirected graph representation of …

Geometry-Aware Methodology for Coupling Mechanism Analysis and Radiation Mechanism Analysis
… the emissions. Mitigation methodologies, such as component placement and grounding post design, are also discussed based on the modal analysis results.</p> <p>The transfer function method is commonly used for RFI problem analysis and mitigation. In this work, using the CMT, a modal-based analysis …

Process development for high powered amplifier Au/Sn eutectic die attach via vacuum furnace
… tolerance stacking resulting in more consistent component placement. MATLAB image processing code was developed to quantify the voiding levels against the accept/reject criteria. Statistical methodologies were employed to troubleshoot root causes for special cause variation of initial attachment …
