Overview: Most EMC design textbooks that cover printed circuit board (PCB) design and layout – including mine – do not cover the special EMC issues associated with Ball Grid Array devices (BGAs), so this webinar covers PCB design techniques that will reduce their emissions and increase their immunity. In particular, how to get good plane meshes under them, and how to deal with their multiple power planes.
Remember, the lowest-cost and quickest design techniques that achieve good EMC (and good SI and PI) operate at the PCB design level, so we need to invest more time and cost in the PCB in order to reduce development time/cost and also reduce the overall unit-cost-of-manufacture – to design products that will make more money, more quickly.

Speaker: Keith Armstrong
Keith Armstrong graduated with honors from Imperial College London in 1972 with a B.S. in Electrical Engineering, specializing in analogue circuit design and electromagnetic field theory.
Between 1972 and 1990 he worked for a variety of electronics companies, as electronic designer, then project manager and design manager. In 1990 he went independent with Cherry Clough Consultants Ltd, providing design services to help achieve compliance with EMC, and with Safety, whilst at the same time helping to reduce time-to-market, design costs, unit manufacturing costs, and warranty costs. Now, in 2012, Cherry Clough has had nearly 800 satisfied customers in almost all areas where electronics are used.
Additional achievements of Keith Armstrong include: Chartered Electrical Engineer (UK) since 1978 Group 1 European Engineer since 1988 Past Chairman of IEE’s Professional Group (E2) on EMC Member of IEE’s EMC & Product Safety Societies Chairman of IEE’s Working Group on EMC & Functional Safety UK expert appointed to IEC 61000-1-2 maintenance team Numerous publications on EMC for Functional Safety UK expert appointed to IEC 61000-6-7 maintenance team UK expert appointed to IEC 60601-1-2 maintenance team (medical device EMC) Published numerous articles, presented many papers, and published three textbooks, on good, cost-effective EMC design practices for everything from circuits through PCBs to products, systems and installations of any size, whether static or mobile.
