Modal Analysis of a Printed Circuit Board
ثبت نشده
چکیده
In the past two decades, modal analysis has become a major tool in the quest for determining, improving and optimizing dynamic characteristics of engineering structures. Not only has it been recognized in mechanical and aeronautical engineering, but also modal analysis has discovered profound applications for civil and building structures, biomechanical problems, space structures, acoustical instruments, electronic components, and nuclear plants.

Hybrid S-Parameters for Transmission Line Networks with Linear/Nonlinear Load Terminations Subject to Arbitrary Excitations
We propose a generalized S-Parameter analysis for transmission lines with linear/nonlinear load terminations subject to arbitrary plane wave and port excitations. S-parameters are prevalently used to model transmission lines such as cable bundles and interconnects on printed circuit boards subject to port excitations. The conventional S-parameter approach is well suited to characterize interact...
متن کاملEnhanced Domain Decomposition–Model Order Reduction Method for Efficient Broadband Full-Wave Analysis of Multilayer Printed Circuit Boards
The approximate modal interface–solution space projection is a combined domain decomposition–model order reduction method for an efficient broadband full-wave simulation of multilayer printed circuit boards. The method features a high efficiency and full-wave accuracy for modern electronic designs. In this paper, a number of enhancements to our previously reported algorithm are presented. The e...

This paper discusses a prognostics methodology for assessing the remaining life of a group of electronic components mounted on a circuit board using a single accelerometer to monitor the life-cycle vibration loads. The accelerometer captures the global circuit board response to enable all components on the circuit board to be analyzed. A case study is presented using a single accelerometer moun...
متن کاملOptimal Machine Setup and Product Clustering for Printed Circuit Board Manufacturing
In the manufacture of printed circuit boards, electronic components are attached to a blank board by one or more pick-and-place machines. Each machine has component magazines that house replaceable feeders. Since component requirements differ among board types, each change of feeders can improve processing time but indicates a machine setup. We develop an integer programming model for the joint...
