The way in which you design a printed circuit board makes a big difference to the overall EMC performance of the product which incorporates it. The principles outlined above must be carried through onto the PCB, particularly with regard to partitioning, interface layout and ground layout. This section gives the engineers the necessary guidance which includes:
Physical partitioning of sub-systems on board
Positioning of components and I/O ports
Ground design on multi-layer PCBs
Critical power and signal tracks routing
Rod is a Chartered Engineer having 32 years of industry experience, with special interests in RF/Microwave development. Since 2015 he has been active in defence electronic systems development and Functional Safety (EN 61508, TÜV certified).
After graduating from the University of Strathclyde in 1990 with a 1st Class Honours Degree in Electronics and Electrical Engineering, he has worked as an electronic engineer in the semiconductor and consumer electronics industries with diverse activities from Digital Audio, RF and Microwave development (including 3D/EM modelling) to university research collaboration.
In 2009, he set up Radiosmith to provide independent design consultancy services and has been involved in radiometric imaging, automotive exterior lighting, medical electronics and capacitive sensing where he has applied his expertise in RF design & test, embedded software (Microchip PIC/AVR), 3D mechanical modelling and PCB layout (experienced Altium user).
Rod became an associate of Cherry Clough Consultants Ltd in 2021 to also provide EMC consultancy services and has enjoyed drawing from his wide electronics and RF design experience when troubleshooting EMI-related problems in products, equipment and systems.
