PEI’s EMI/RF shields have snap-on, snap-off covers, allowing easy access at any time to components within the shields. These shields are designed to protect components from radio frequency/electromagnetic interference and environmental hazards, and to provide electrical grounding. Standard forming tools are available in any size and shape to create covers that attach onto a fence yet can be removed and replaced easily.
Our photochemically etched fences have grooves etched approximately 50% of the material thickness, so PEI’s custom spring finger designs snap into them firmly. PEI will quote on any existing shield that has a removable cover and apply our design to it; the only tooling charge will be for a phototool, NOT for a forming tool. Our innovative technology and extensive etching capabilities allow us to manufacture reliable, easy-to-use shielding at low cost and with fast deliveries.
Shielding options for circuit board applications include:
- One-piece or two-piece construction.
- Standard base materials including brass, tin, tin-lead, nickel, copper, and cold-rolled steel, all of which can be provided with solderable plating.
- Nickel-silver base material, which does not require additional finishing because it is already solderable
