Shielding Effectiveness Design Review

Online Numerical Estimates Are Currently Unavailable

This page does not currently provide a calculated shielding effectiveness value. Use the checklist below to prepare a design review request.

Material and thickness alone do not establish the shielding effectiveness of an assembled product. Openings, seams, grounding, the interference source, and the test arrangement also affect performance.

Information to Include in Your Review Request

• Frequency range and interference source: Relevant operating frequencies, the affected circuit, and the source location when known.
• Performance target: Required attenuation or EMC test limits, together with the test method or specification you need to meet.
• Material and finish: Alloy or grade, thickness, surface treatment, and available material datasheets.
• Dimensions and drawings: Shield outline, height, PCB layout, component clearances, and any internal partitions.
• Openings and seams: Aperture dimensions, shape, spacing, ventilation holes, and frame-to-cover contact details.
• Grounding and assembly: PCB ground connections, solder pads, clips, gaskets, and the intended assembly process.
• Existing evidence: Prototype measurements, simulation results, or a description of the interference issue, if available.

Include the details you already have and identify any parameters that are still undecided. Use the remarks field on the quote form to describe the review you need.

Plan for Verification

A design review can help identify the factors to evaluate. Shielding effectiveness should be verified on the assembled design using a test arrangement appropriate to the application. This page provides no numerical performance guarantee or certification result.
