EMC Shields & RFI Shielding

EMC/RFI Shielding Solutions

EMC / RFI shielding is necessary across many industries to avoid any interference from electromagnetic signals. Used across electronics, telecommunications, automotive control, avionics and more, shielding gaskets are vitally important in many critical applications.

We provide standard and bespoke RFI and EMC shields and shielding solutions to meet the very latest Electromagnetic Compatibility (EMC) directives. A full range of products is available from off-the-shelf standard cans through to complex multi-cavity labyrinths.

What is an RFI Shielding?

This is a Radio Frequency Interference shield which basically means that the equipment is protected against electromagnetic waves that could cause interference and malfunction. It does this by applying a shield, usually an acrylic-based spray, foam or brush-on coating which is applied to the electronic housing. The RFI Shield protects the housed electronics from any unwanted interference that could eventually disturb and degrade the overall efficacy of the device.

The same applies to the reverse situation; in many technical appliances, we don’t want any internal interference from the electronic equipment which is why a number of products employ RFI gaskets to prevent this. This is why we offer RFI shields on a range of our products so that they work seamlessly in every situation.

What is TEC Shielding?

TEC Shield has the appearance of metal graph paper. It is a 0.40mm copper sheet with a semi-etched cut-n-fold grid system at a pitch of 0.2″. It is electroplated with Bright Acid tin for long-life solderability.

TECshield is essentially our ‘on-the-bench’ modelling system developed to enable RFI/EMC development engineers to prototype shielding cans, fences and lids quickly and easily. More importantly, the electronic performance or the ‘shielding effectiveness’ will be closer to a custom-manufactured can when compared to traditional ‘modelling’ techniques. The TECshield range provides a professional and effective method to evaluate a solution.

The etched fold line principle used in the design and construction of photo-chemically machined shielding cans provides an easy method of assembly. As ‘Origami’ is for paper, the use of TECshield, with its etched fold lines, can be likened to starting with a blank sheet of paper.
