Schneider, Matthew J. M.S., Purdue University, May 2010. Design Considerations to Reduce Conducted and Radiated EMI. Major Professor: John P. Denton. This work evaluates the effects of conducted and radiated EMI due to improperly designed circuits or printed circuit board (PCB) layouts. Common circuits used in a wide range of electronic devices are evaluated using both good and poor design tech...

The purpose of decoupling capacitors on printed circuit boards is to meet the instantaneous current demands of high-speed active devices while minimizing power bus noise. Embedded capacitance is an alternative to discrete decoupling capacitors and is achieved by taking advantage of the natural capacitance between the power and ground planes. This paper investigates the electrical properties of ...

This paper presents the robust colour image segmentation algorithm which can be used extensively in automated optical inspection system on the printed circuits boards (PCB) assembly line. The robustness of the presented algorithm is increased by low computational effort what dedicates this approach to on-line vision systems explored in high-speed production lines. The second advantage of the pr...

For σ−PWB extensions, we extend to modules the theory of Gröbner bases of left ideals presented in [5]. As an application, if A is a bijective quasi-commutative σ − PWB extension, we compute the module of syzygies of a submodule of the free module A.

Prior to the mid 1980s, the dominance of through-hole packaging of integrated circuits (ICs) provided easy access to nearly every pin of every chip on a printed circuit board. Providing accessibility and controllability for board testing was simply a matter of probing the board. With the advent of surface mount packaging, the accessibility for probing printed circuit boards began to diminish. L...

Remaining life assessment is an estimate of the reliability of a product in its life cycle application environment based on health monitoring and prognostics analyses. This paper reviews remaining life assessment methodologies that are currently employed for engineering products, and discusses their potential applicability to electronic systems. Based on this review, a generic ‘Health Status As...
