Why 50% of EMC Testing Fails

According to electromagnetic computability testing experts, almost 50% of electronic products don’t meet the EMC requirements when they are first tested.

There are many reasons that lead to this failure, and manufacturers and designers are trying their best to improve the success rate.

However, the growing awareness of this problem has made product manufacturers and designers more cautious about the use of EMC software, better EMC design considerations, and reduced circuit dimensions.

The reasons for EMC testing failures

Over the last few years, experts have looked into the rising percentages of products failing EMC testing the first time.

While a few of the electrical products meet the EMC objectives partially, many don’t follow them at all.

For example, medical products are slightly more successful than other products. They have an initial failure rate of 40%.

There may be two factors contributing to this small success: one, they are more conservatively designed, and second, the product standards allow justified derogations from the required limits.

There are five critical reasons why electrical products fail their initial EMC testing.

They fail to apply EMC principles.

All the products lack the knowledge of the EMC principles.

There are unpredicted interactions among several circuit elements.

There are widespread applications of incorrect EMC regulations.

Most of the products incorporate non-compliant modules. Some even use subassemblies in the final product.

Better EMC testing

Many manufacturers claim that EMC testing machines don’t operate to the best extent, and that is the sole reason why their products fail to pass the test the first time.

You can eliminate this problem by getting the products tested from some of the best EMC testers in the industry.

They have advanced test laboratories with a wide range of tools to check the products.

The advanced tools cater to a broader range of certification requirements that include vibration, temperature, shock, environmental, impact, and ingress.

Before searching for a company that offers the best EMC testing, you need to check if they provide the following services:

CE testing

Radio testing

C-tick and RCM testing

Automotive EMC testing

Military and aeronautic EMC testing

Railway and train testing

Interference investigation

Radiation hazard management

RF Shielded Enclosure Manufacturing

Magnetic (EMF) Shielding

Ingress Protection (IP) Testing

Impact Testing (IK Testing)

Vibration Shock Testing

Manufacturers should consider EMC at the initial stages of designing the process.

EMC test operators believe that electrical products fail to comply with the EMC principles because the manufacturers don’t pay enough attention to the requirements during the designing process.

Once you focus on the EMC goals before the designing starts, the product will automatically follow all the necessary points on the checklist as the development process starts.

Every product should consider a few EMC requirements before testing such as target specifications, system architecture, design rules, and regulatory evaluation.

If the product follows these targets, it may pass the EMC testing in its first attempt, and the 50% failure rate will go down significantly.
