Welcome to Cherry Clough Consultants

We are independent consultants who help designers, manufacturers, system integrators, installers, and users deal quickly and cost-effectively with real-life interference (EMI), or comply with the EU's EMC and Safety Directives and similar regulations. All applications, all industry sectors, worldwide.

Our SI, PI & EMC design techniques are very well-proven for 24 years to significantly reduce design / development time and cost; overall cost of manufacture; warranty costs, and financial risks, at all frequencies up to 26GHz (so far!), whatever the relevant EMC standards: from the 'generics', to the toughest such as DEF STAN 59-411 Land Class A. 

We also have well-proven guidelines for reducing functional safety risks, or other risks, that could be caused by EMI.

NEW: EMC Short Course in South Africa:  31 Oct - 6 Nov 2018

Presented by MESA Solutions (Pty) Ltd and Cherry Clough Consultants Ltd, to be held at the Denel Houwtec test facility, near Grabouw, Western Cape, South Africa. To register, and for more information, please email: info@mesasolutions.co.za.

Given MESA Solution's close links with academia, it is only natural that we offer both fundamental and advanced training in EMC, which often does not receive enough consideration during the design process. This will be MESA's primary training event for 2018, supported by the IEEE 4th Global Electromagnetic Compatibility Conference (GEMCCON) that takes place immediately afterwards, from 7 to 9 November 2018, at nearby Stellenbosch University.

The strong foci of this course are the underlying EMC principles and the practical design of PCBs, equipment, systems and installations. This includes incorporating hardening measures to reduce the effect of interferenceWe will investigate the effects of unwanted electric and magnetic field coupling as demonstrated through a number of key experiments. The influence of ground loops, poor equipment placement and connections, and the effects of common conductors will also be considered. 

Finally, the practical design of circuits, PCBs, interconnections, filters and shields relevant to the interference frequencies being considered, will provide the attendees with the necessary tools to handle the majority of EMC issues quickly and cost-effectively.

Keith Armstrong's training courses now available for on-line purchase
Anyone who buys a course module will be automatically updated with new versions for free, for some number of years (we haven't decided how many yet). The updating versions will be complete, with change records so you don't have to scan right through them to find the updated material.

This way of learning good EMC design is better than buying textbooks (which are out of date for years) or attending annual training courses (where most of the material is the same as the year before, you can't simply attend the new or improved material, and you have to pay full price again).

The new site for easy and free access to the huge range of Keith Armstrong's published material, and a lot of additional stuff such as EMI Stories, EMC Design Checklists, Webinars, and more.

These are colour-printed 'on-demand'. They are not available new from Amazon or other resellers,
who might mistakenly list them as being "out of print"
