SSP’s EMI shielding webinar is available on-demand. Watch it here.
Specialty Silicone Products (SSP) is sharing an in-depth EMI shielding webinar for on-demand viewing. EMI/RFI Gasketing: Outside the Box Solutions to Protect What’s in the Box is also available on YouTube and contains valuable lessons about protecting enclosures against electromagnetic interference (EMI).
SSP’s EMI shielding webinar dispels myths about EMI shielding silicones, examines common drawing specifications, and explains how its EMI gasket materials reduce costs and improve performance. This webinar is several years old but has nearly 4,000 views.
EMI Shielding Silicones: Now and Then
Filling EMI shielding elastomers with metal particles isn’t new, but some engineers still believe that all electrically conductive silicones are too hard and too brittle. These skeptics may also claim that shielding silicones are limited by mold-size dimensions and aren’t thin enough for newer, thinner electronic designs. As SSP’s webinar explains, however, its materials address these concerns and offer options besides what appears on old part drawings or blueprints.
Silver isn’t the only available fill material either. Silicones that contain silver particles provide excellent EMI shielding, but silver is subject is to volatility in the precious metals market. If the price of silver skyrockets, an EMI gasket that costs $15 today could cost several times that amount next year. In industries such as aerospace and defense, cost overruns like this are unacceptable. Delays caused by long lead times are problematic, too. Fortunately, SSP’s EMI elastomers also address these challenges.
EMI Shielding Gaskets and MIL-DTL-83528
Engineers need cost-effective, readily-available materials, but some EMI shielding gaskets must meet MIL-DTL-83528 Type A, B, C, D, and K requirements. Older part drawing may even reference the MIL-G-25988 standard instead. SSP’s solutions include materials that meet the lettered sections of the MIL-DTL-83528 specification. SSP also shares third-party shielding reports, indicates which EMI silicones have a Qualified Product Listing (QPL), and even offers fluorosilicone compounds for chemical resistance.
SSP’s EMI shielding silicones are available with silver-coated particles, but SSP’s nickel-graphite filled materials provide silver-like shielding effectiveness at a lower price. As the EMI shielding webinar explains, SSP also supplies silicones that are filled with nickel-coated aluminum particles for corrosion resistance.
SSP’s ability to produce EMI roll sizes (in addition to molded sheet stock and ready-to-mold compounds) also makes materials manufacturing part of the performance equation.
