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 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.
Why use RFI shields?
RFI shields are essential to protect sensitive electronics from both external and internal electromagnetic interference. Without proper shielding, devices can malfunction, lose data integrity or fail compliance testing. Our RFI shields deliver high performance across a wide frequency range, ensuring both regulatory compliance and reliable operation of critical systems.
Applications for RFI shielding
RFI shields from Tecan are used widely in: telecommunications, defence electronics, medical devices, automotive control units, avionics, industrial automation, and consumer electronics. From preventing crosstalk on high-density PCBs to meeting strict EMC standards in mission-critical aerospace systems, our RFI shields provide proven results.
Precision manufacturing for RFI shields
Because our shields are produced by photo-chemical etching, we achieve very fine apertures, sharp edges and fold lines without introducing stress or burrs. This means our shielding cans can integrate ventilation slots, logos or intricate design features without costly secondary machining — ideal for complex, multi-cavity RFI shield assemblies.
Prototyping with TECshield and TECpack
Our TECshield semi-etched copper sheets and TECpack prototyping service allow engineers to trial shielding concepts rapidly on the bench. This reduces development cycles and helps validate shielding effectiveness before committing to full-scale manufacture. It’s a unique way to accelerate RFI shield development while keeping costs under control.
Why choose tecan for RFI shielding?
With over 55 years of experience, we combine etching expertise with in-house plating and forming. This means you can specify shields with additional finishes (tin, nickel, silver, gold and more) to improve conductivity, solderability and durability. Our ISO-accredited processes ensure full traceability and reliable performance in every shield we supply.

Yes. Tecan manufactures precision photochemically etched EMI/RFI shielding components, including shielding cans, fences, enclosures, gaskets, apertures and fine-feature mesh.
EMI/RFI shielding is metalwork that contains or blocks electromagnetic and radio-frequency interference between electronic components, protecting signal integrity. It is used across electronics, communications, aerospace, medical and data-centre hardware and more.
Photochemical etching produces clean, repeatable fine features and precise apertures across thin sheets without burrs that would compromise fit, contact or shielding performance. Because the process uses digital tooling, shielding designs can be changed quickly during development.
Tecan etches shielding cans, labyrinths, two-piece cans and fences, board-level enclosures and lids, shielding gaskets, apertures and honeycomb or fine-mesh shielding, as well as stepped and hybrid lids.
Tecan offers a flexible choice of base metals. Shielding components are typically etched from appropriate metals such as nickel-silver (alloy 770), copper, brass, Aluminium, Mu-metal / High-Permeability Alloys and stainless steel. For material options, see our guide to choosing the right metal.
Yes. With decades of experience, Tecan combines etching expertise with in-house plating and forming. You can specify shields with additional finishes (tin, nickel, silver, gold and more) to improve conductivity, solderability and durability. Tecan’s ISO-accredited processes ensure full traceability and reliable performance in every shield we supply.
Yes. Because photochemical etching uses digital tooling, Tecan produces custom shielding cans and fences to your dimensions, with prototypes made directly from drawings and the same design scaled to volume without new tooling.
Tecan can supply shielding parts flat or formed and assembled, including folded cans, fences and lids, through its onsite forming and assembly capability.
