PEI Develops RFI/EMI Shields with Snap On and Snap Off Covers

February 9, 2010

PHOTOFABRICATION ENGINEERING, INC. (PEI), Milford, MA, (February 9, 2010) is introducing a full line of EMI/RF shields with 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

PEI’s manufacturing process has achieved ISO-9002:2008 and has been awarded certification under AS9100, quality standards established by the aircraft and aerospace industry. Applications for PEI’s line of shielding products include aerospace, defense, and commercial electronics; communications and telecommunications equipment; medical and biomedical equipment; and appliances – in fact, virtually any application where board components must be protected from RF interference.
