EMI RFI Etched Shielding Components

Plating / Surface Coating

Lead free plating materials include Silver, Nickel, Gold, depending upon the customer's specific electrical and thermal conductivity requirements.


Photo etching is an economical and flexible method of production. It can produce a wide range of EMI / RFI shielding solutions, from standard shielding / screening cans through to multi cavity labyrinths, without the cost penalty for complexity of design. There is no limitation on the complexity of shape; any aperture configuration can be accommodated. Features such as etched score lines (fold or bend lines) to allow the shields to be stored flat for easy forming by hand or automated using simple tooling. The bend lines enable enclosures to be formed with excellent coplanarity. Plimsoll lines can be etched to prevent solder leaching. Special coatings are available to improve attenuation of high frequencies, selective, dielectric coating enables lower profile cans to be utilised safely. Very quick delivery from 'agreed design' to supply of finished photo etched shielding / screening screens. Using our in-house forming and spot welding facility ACE has total control over quality and delivery. The digital tooling is very inexpensive and modification to tooling can be done very quickly and economically. All parts are burr and stress free leading to minimum assembly time on the line. Parts can be supplied plated for improved solderability, functionality, aesthetics and protection.

Typical components manufactured

  • One-piece etched screening cans
  • Two-piece etched screening cans
  • Labyrinth (Multi-compartment) etched screening cans
  • Connector shields
  • Enclosure shields
  • Socket and enclosure insert shields
  • Conductive gaskets
  • Vents, grilles, meshes and windows

Faster Speed

For rapid sampling, the technology of half etched folding lines allowing hand forming without hard form tooling, can be the most effective solution.
