EMI/RFI Shielding

Electromagnetic interference is a serious and increasing form of environmental pollution.
With miniaturisation and the increasing density of components in electronic and electrical systems and EC directives on electromagnetic compatibility, there is an increasing need for suppliers of EMI/RFI screening and shielding that have an in-depth knowledge of the industry’s requirements and a high degree of flexibility in order to meet those needs effectively..

PRECISION MICRO provides that flexibility in design, supply and cost savings through its imaginative approach to multi-process manufacture and dedication to customer partnership.

Flexible Design

There is no limitation on complexity of shape, allowing easy partitioning round existing circuitry
Any aperture configuration can be accommodated at no cost penalty.
Bend lines enable screens to be stored flat for subsequent easy and accurate forming by hand on assembly lines.
Proven attachment designs ease SMT and ‘through-hole’ assembly.
Connecting tags permit easy assembly of a complex array of interconnecting screens.
Fixing tabs enable lids to be connected simply.
Thin metals can be used in restricted spaces.
Multi-compartment cans improve space efficiency.
Coatings are available to improve attenuation of high frequencies.
‘Plimsol line’ features can be incorporated to prevent solder leaching

Dependable Supply

Very quick delivery from ‘agreed design’ to supply of finished screens.
PRECISION MICRO has production, plating, forming and spot welding facilities in-house to ensure full control over delivery and quality.
Over 1,000 different metal types, grades and thicknesses available from stock, including steels, brasses, coppers, magnetic metals, etc.

Cost Saving

Tooling is very inexpensive.
Modification to tooling can be done quickly and economically.
There is no limit to quantity, small lots for development, as well as production quantities can be produced cost effectively.
All parts are burr and stress free leading to minimum assembly time on line.
Parts can be supplied plated for improved solderability, functionality, aesthetics and protection. As well as having one of the most advanced PCM capabilities in Europe, PRECISION MICRO can offer spot welding, soldering, precision reaming and other sub-assembly operations to hand.

The Company has also developed a 'modular ‘RF Screening System’ with which development engineers can produce functional prototype shielding enclosures for test purposes in a matter of minutes using simple tools. The product comprises enclosure wall strips with etch lines that enable them to be readily formed to accommodate and profile. Lid section is also supplied and the entire system conforms to the dimensional requirements of standard 0.1”matrix prototyping board.
