As microprocessor speeds continue to increase, so does the potential for EMI leakage through the smallest apertures in board level shields. Laird Technologies’ drawn board level shields are designed to provide additional near-field and far-field circuit isolation (attenuation) at higher frequencies by eliminating the apertures found in the corners of traditional board level solutions. Drawn board level shields utilize small ground trace sizes, thereby preserving space on the circuit board.The data set forth in all text, tables, charts, graphs and figures herein are based on samples tested and are not guaranteed for all samples or applications. Such data are intended as guides and do not reflect product specification for any specific part.


 Features  

  • Solid corner designs when additional circuit isolation (attenuation) is required at higher frequencies
  • Available in heights up to .250" (6.4 mm) with length and width dimensions from .300" (7.6 mm) to 2.0" (50.8 mm)
  • Tape and reel packaging provides an economical and automated SMT attachment method
  • Available in cold rolled steel, brass, stainless steel and nickel silver
  • Mold-in-place and form-in-place elastomers can be combined with drawn board level shields to achieve shielding of multiple components with a single part
  • Available with an EZ Peel scored cover feature; allows for easy top section removal for component repair and re-sealing
  • Ventilation holes as needed for solder outgassing.
