Conformal coating metal inks

1 January 2018 Manufacturing / Production Technology, Hardware & Services

Henkel Adhesive Technologies’ electronics business introduced two novel, conformal coating metal inks for semiconductor package-level electromagnetic interference (EMI) shielding. LOCTITE ABLESTIK EMI 8660S and LOCTITE ABLESTIK EMI 8880S offer superior flexibility in deployment and design, as they may be used with cost-effective spray coating equipment, while providing EMI shielding performance comparable to or better than capital-intensive, thin film metal deposition techniques. With excellent adhesion to a variety of epoxy moulding compounds, both materials enhance long-term reliability performance.

LOCTITE ABLESTIK EMI 8660S provides shielding at a frequency range of 500 MHz to 10 GHz, while LOCTITE ABLESTIK EMI 8880S offers effective shielding for a wider range of 10 MHz to 10 GHz. The thermally-cured coatings may be deposited as thin as 3 to 5 μm to accommodate slim, next-generation package profiles, and are compatible with Henkel compartment shielding materials used to isolate components within System-in-Package (SiP) devices.
