Printed Circuit Board Layout for EMC and Signal Integrity

Description

This one day training session on the design and layout of high speed printed circuit boards stresses the fundamental concepts that board designers need to be familiar with to avoid electromagnetic compatibility and signal integrity problems. Students completing the course will be able to make good decisions regarding component selection, component placement, and trace routing. In addition, students will be able to design effective power distribution and grounding strategies.
