  2. 1. High Aspect Ratio Microstructures in Flexible Printed Circuit Boards : Process and Applications

    Author : Hanna Yousef; Klas Hjort; Mikael Lindeberg; Peter Leisner; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; flexible printed circuit boards; polyimide; through-hole vias; ion track technology; thermoelectricity; thermopiles; substrate integrated waveguides; millimeter wave devices; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Flexible printed circuit boards (flex PCBs) are used in a wide range of electronic devices today due to their light weight, bendability, extensive wiring possibilities, and low-cost manufacturing techniques. The general trend in the flex PCB industry is further miniaturization alongside increasing functionality per device and reduced costs. READ MORE

  4. 2. Computation of EMC Properties of Slots and Printed Circuit Boards

    Author : Jan Carlsson; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrugations; crosstalk; FDTD; spectral domain; EFIE; chokes; Finite Difference Method; printed circuit board; transmission line network; EMC analysis; PCB; transmission line theory; radiated emission; Method of moments; MM; MoM; electric field integral equation; soft and hard surfaces; slot; radiated susceptibility;

    Abstract : This thesis deals with the numerical solution of electromagnetic compatibility (EMC) problems for electronic systems, such as radiated emission, susceptibility and crosstalk on printed circuit boards and transmission through slots. The analysis of printed circuit boards is done by using an electric field integral equation (EFIE) expressed in the frequency domain, which is solved by using the method of moments. READ MORE
