10a - Advanced PCB design techniques for cost-effective SI, PI and EMC in 2021
Provides 7 hours towards CPD
Updated for 2021!
Module 10A (replaces Module 10)
This course is designed to help design engineers:-
– Reduce cost by eliminating enclosure shielding
– Reduce interference with co-located wireless datacoms (e.g. increase receiver range for GSM, GPRS, 3G, 4G, etc.)...
– Allow co-located GPS antennas...
– Use RF power devices (including isolating DC/DC)...
– Make high-speed processors / DSP function correctly (achieve good signal integrity, SI, and power integrity, PI)...
– Use the latest IC technologies (e.g. 15nm or smaller silicon processes), BGAs and ‘chip scale’ packages...
– Reduce time to market and compliance costs

Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.Join EMC standards TODAY!
