LOCTITE® ABLESTIK 8008HT
Bekannt als ABLECOAT 8008HT
Merkmale und Vorteile
A 1-part, proprietary hybrid-chemistry, lead-free, electrically and thermally conductive die-attach adhesive specifically formulated for high-power devices in a high-UPH environment.
LOCTITE® ABLESTIK 8008HT die-attach adhesive is perfect for high-power devices in a high-UPH environment. A lead-free alternative to soft solder and eutectic, it can potentially reduce the layers of backside metallisation required. It can be applied to a wafer backside by stencil printing, B-staged in an oven, then be cured after die attach in an in-line process exhibiting a consistent, void-free bond line without bleed. Should be used with a pressure-sensitive dicing tape. Not compatible with UV dicing tapes.
