EMC Aware
Electromagnetic Interference (EMI) is increasingly polluting the electromagnetic spectrum and disrupting a wide range of electronic and electrical equipment and services. To help Australian industry deal with this growing problem and meet national and international Electromagnetic Compatibility (EMC) standards, two EMC Aware courses, EMC - A Problem on the Horizon and EMC - Solving the Problem, are now available.
These EMC Aware courses provide an informed and practical introduction to the EMI problem and the EMC solution. Both courses are based on the expertise of key regulatory bodies, testing and specialist agencies, major manufacturers and education and training institutions including the EMC research conducted by Dr Tee Tang at the Queensland University of Technology (QUT).
Course Benefits Include:
-
Better understanding of national and international EMC standards and measurement procedures
-
Full understanding of the impact of EMC on the design and manufacturing processes and on the importing/distributing and selling of products; and
Increased awareness of EMI and the necessity for EMC standards
Improved ability to meet national and international standards
EMC Course Designers
Dr Tee Tang graduated with a Bachelor of Engineering & PhD in Electrical Engineering from the University of Queensland. He is currently a Senior Lecturer & Head of Undergraduate Program at the school for Electrical & Electronic Systems Engineering at QUT where he has also set up the EMI/EMC Laboratory. Dr Tang has taught in a wide area of subjects, including digital & analogue electronic circuits, signal & noise theories, communications, microwaves, antennas, electromagnetic wave transmission and propagation.
Chris Cartwright has spent
many years with Ericsson in design, manufacturing and training roles. Initially,
Chris was exposed to the EMI/EMC issue during the design of a DC/DC converter
and later as part of system test implementation of 2Mbit Analogue to Digital
Converters. Previously the Manager of the AEDC, Chris brings together EMI/EMC
experience and project management skills to the EMC Aware courses and to
the establishment of EMC Networks.

| Pre-Compliance Testing |
No matter what product you manufacture, import or export, EMC testing is a cost that you would rather do without. With the introduction of EMC legislation, EMC Testing is the safest method of compliance for entrance to local and international markets. The best you can hope for is to do everything in your power to limit the cost of EMC testing.
There are many damaging impacts to your company that can take place if your product fails at a testing house. These include:
-
Waiting anywhere from 2 weeks to 3 months to obtain time for the re-testing of your product.
-
Expensive board and/or hardware redesign - a headache that I'm sure you can do without
-
Lengthy delays in reaching the market meaning lost sales and market share opportunities for every day that your product is late to the market
-
Embarrassing yourself to your management and to your customers! Learn how to set up simple conducted and radiated emission tests correctly the first time.
-
Each time you have a product tested in a testing house, it will cost somewhere in the vicinity of $1,000 - $2,000. One visit to the EMC Pre-compliance Testing course is a far better investment
…. and EMC test equipment is expensive - learn how to more closely select the most appropriate pre-compliance testing equipment for your current and future needs
What better way of hearing how to minimise the cost of EMC testing than from the Technical Director of a NATA approved EMC Testing House.
This 2 day course will provide participants with the knowledge and techniques to minimise the cost of bringing products to the market place by limiting the cost of EMC testing. The course will include practical demonstrations of equipment that will assist in pre-compliance EMC testing.
Course Benefits Include:
-
Benefits of pre-compliance testing
-
Understanding of national and international EMC Regulations
-
Procedures that need to be followed before submitting products for EMC Compliance Testing
-
When to test within your own organisation and when you should approach a testing house
-
Awareness of the cost of non-compliance
Who should attend?
Engineers, Technicians, Technical Officers and Technical Managers from electronic and electrical manufacturing, importing and distributing companies/organisations

EMC and Building Cabling Installation
In a society heavily reliant on structured cabling systems for communications, there is an increasing problem ensuring signal integrity - particularly with Electromagnetic Interference. Cable suppliers must not only be aware of EMC requirements, but ensure that designers have all the relevant information to ensure an Electromagneticly Compatible installation. Additionally, designers and installers must know the requirements of the relevant standards and the correct techniques to install cabling systems to ensure Electromagnetic Compatibility. This one day course looks specifically at EMI/EMC and its effects on structured cabling systems, and what suppliers, designers and installers need to do to comply with the relevant standards.
Equally important, from a purely commercial
perspective, contractors must ensure their total project does not suffer
financially, such as failure to meet "practical completion", having
"liquidated
damages" applied, or worse - "consequential losses" apportioned.

Presented by Mr John Howard |
Grounding, Shielding, Cabling, Filtering and Transient Suppression are all important areas in minimising Electromagnetic Interference but without designing your board correctly in the first place, interference is likely to occur. This will add significant cost and time to re-design your product and will mean that extra attention will need to be placed when designing other parts of the "system" to "hide" the interference.
Many design engineers have highlighted that there was a strong need for a PCB Design for EMC course. It’s now here and who better than to teach it than a leader in the field - Mr John Howard. Yes, John Howard! No, not the one that you were thinking of but one who is an expert in this critical field. John Howard is an EMC consultant based in Sunnyvale, California USA. Mr Howard has worked for companies including Hewlett-Packard, Motorola/Four Phase Systems, Lockheed Research and Tandem Computers.
The PCB Design for EMC workshop will focus specifically on designing boards to minimise (and hopefully) eliminate Electromagnetic Interference at the board level.
