EMC shielding

Why must we achieve EMC?

Other than the fact that products which do not comply cannot be marketed legally in the EC, more disruptive manifestations would exist that could affect the very manner in which we lead out lives. These encompass health and safety issues, the security of data processing and the functioning of vital electronic equipment. ABS braking systems, engine management systems, telecommunications, and data transfer plus the security of both commercial and miliary data could be readily compromised without adequate screening.

Other issues such as the dangers to health due to the emissions from mobile telephones and computer monitors plus the ongoing research into the effects of living in close proximity to high voltage overhead power lines, all form part of the global concept of EMC. Some aspects can be easily controlled but others will continue to remain unresolved for years to come. The doomsday scenario of EMC (Electromagnetic Pulse) resulting from high altitude nuclear explosion would certainly lead to almost total loss of commercial communications and data processing plus much of the non-hardened military network, whilst at the same time avoiding the mass destruction of the infrastructure necessary for future use, possibly by the instigator of the blast.

In other words, potential chaos with no communications, services, power, media such as TV or radio and the loss of many forms of transport.

STORIES

How can EMI be contained?

In simple terms, most ‘shielding’ problems could be solved by welding the equipment into seamless steel box. The problems that this would lead to are obvious, access would be impossible, power unavailable, visibility would be zero and the equipment would rapidly overheat.

STORIES

How are seams and joint lines sealed?

Joints should be regarded as permanent or temporary (permitting occasional access). Permanents joints and seams should be welded, soldered, or conductively bonded with a special adhesive.

UK-based EMC company acquired

Nolato acquired UK-based P&P Technology in spring 2023. The company, based in ­Maldon, Essex, northeast of London, provides component- and materials-based ­electronics shielding solutions to ensure electromagnetic compatibility (EMC).
