Dow introduces easy-to-dispense gap filler with strong thermal conductivity and slump resistance for efficient assembly
Thermal interface material can replace traditional, fabricated thermal pads, supports automated assembly for 5G technologies
Dow’s new DOWSIL™ TC-4040 Dispensable Thermal Pad supports automated dispensing, stencil printing and screen printing. Piston pump and plunger metering is recommended for dispensing because of the material’s high filler loading. DOWSIL™ TC-4040 Dispensable Thermal Pad offers a superior extrusion rate and delivers precise component coverage with needle dispensing. This high thermally conductive material (4.0W/mk) has a working time of two to four hours.
DOWSIL™ TC-4040 Dispensable Thermal Pad is a reworkable gap filler that is supplied as a two-part liquid component kit and has a shelf life of up to six months at room temperature due to its dependable material properties and ease-of-storage. It has excellent reliability of thermal management performance that can resist various harsh environmental testing (e.g. 1000-hour aging test at 150C, 1000 cycles thermal shock from -45C to 125C and 1000-hour 85/85% RH (high-temperature/high-humidity) aging test).
DOWSIL™ TC-4040 Dispensable Thermal Pad is available in Greater China and throughout Dow’s extensive global network of distribution partners.
