I kow there have been similar requests on this forum but can anyone reccommend any referance texts for PCB layout as regards EMC? Reccommendations I have had so far are:- EMC And The Printed Circuit Board - Mark Montrose 1998 Printed Circuit Design Techniques For EMC Compliance - Mark Montrose 1996 and the ubiquitous Johnson & Graham's Handbook of Black Magic! Anybody use these? TIA Adam Hawes PCB Design Eng. GenRad Ltd.
