EMI Shield — SnapShot EMI Shield is a board-level, multi-cavity shielding product. The metallized, thermoformed plastic shield reportedly is easy to install and remove, and accommodates intricately shaped designs. It is electrically insulated on the inside and attaches to the PCB using a snap mechanism. Installation of the shield begins by applying BGA spheres to the PCB panel using a standard stencil printer with a special head. After the PCB has been populated and reflowed, the shield is snapped in place. Because the installation is not permanent, it can be removed by hand without special tools. The product is packaged in bulk, trays or tape-and-reel. W.L. Gore & Associates Inc., Elkton, Md.

EMI Gaskets — Soft-Shield 7000 EMI Gaskets feature non-urethane soft foam core materials that reportedly provide high levels of shielding and long-term physical stability. The products combine a highly conductive, plated cloth wrapper with a customized polymeric foam core and high-temperature, pressure-sensitive adhesives. They provide more than 90 dB of EMI attenuation from 20 MHz to 10 GHz. The gaskets are said to maintain their physical and mechanical integrity in high operating temperatures for a service life exceeding 10 years, and demonstrate minimum compression set at elevated temperatures (125°C) over long operating periods. The gaskets come in standard lengths and cut-to-length strips in a range of cross sections. Chomerics, Woburn, Mass.

Epoxies — SC 2000 Series Single-component Epoxies are suitable for bonding metal, ceramics, glass and other substrates. These heat-cured, self-leveling adhesives require no mixing and reportedly provide thermal stability, corrosion resistance and gap-filling properties. They are available in four 100 percent solids formulations to accommodate a range of applications. SC 2001 features viscosity (250,000 cps at 75°F) and thermal conductivity suitable for potting and encapsulating. SC 2002 is a structural adhesive resistant to oil. SC 2003 is formulated for applications requiring greater sag- and run-resistance. SC 2004 is resistant to aluminum sulfate solutions. Devcon, Danvers, Mass.
Installation Tool — The PTS Cable Tie Installation Tool is designed for use with subminiature through standard cross-section cable ties. Pneumatic, push-button operation reportedly allows the product to automatically tension and cut off the cable tie in a fraction of a second. A cushioned, non-slip handle and controlled tip ejection that retains the cut-off tip are featured. The narrow nose is said to improve visibility and access to bundles in confined areas. Panduit Corp., Tinley Park, Ill.
Potting Compound — Trigger Cure is a two-part, UV-curing potting compound. The product features a 1:1 ratio and can be applied via disposable tip static mix dispensers. Exposure to longwave UV light is said to cure the product to a depth of 0.25" in 20 seconds or less. The remaining liquid resin gels in 7 to 20 minutes; full cure is achieved in 24 hours at room temperature. The compound reportedly provides the fast-cure benefits of light curing with the chemical cure of traditional potting compounds. It is suitable for electronic applications such as the potting of sensors, PCBs and LEDs. Dymax Corp., Torrington, Conn.
Drawing Tool — The Tru Draw Online Drawing Tool is a Web-based tool that allows users to access an online catalog of RF coaxial connector drawings, modify them and request a custom part quote. This interactive drawing/text tool can add grid lines, part modifications, colors, text and comments to the online product drawings. Featuring a template with industry-standard graphics interfaces, it reportedly permits instant e-mail dialogue with the company's product development engineers. The tool is said to improve accuracy by allowing design engineers and the company to focus on identical part drawings with comments and changes highlighted in color if desired. The product can be downloaded from www.trucorporation.com. Tru Corp., Peabody, Mass.
