A thick film dielectric and conductor system improves the mounting of silicon ICs to aluminum substrates. Provides low thermal resistance between the chip and heat sink in applications such as HB LEDs. The glass system of the Pb- and Cd-free dielectric paste was developed to offer thermal conductivity on both 3003- and 6061-grade alloy aluminum substrates. Reduces bowing by closely matching the CTE of aluminum. Also, a Pb-free silver conductor paste, fired together at 550°C with the dielectric paste, provides solderability and adhesion. Is for applications such as direct-mounted LEDs.

DCA-FD is a modified silicone conformal coating said to dry to the touch in 20 min. Increased solids content reportedly gives 35% greater coverage per liter compared to standard DCA. Has a wide operating temperature range and is suitable for a range of commercial and high-rel applications. Has lower VOC levels compared to standard DCA. Has excellent adhesion and is resistant to most solvents, lubricants and chemicals. Is highly resistant to mold growth and UV light. Can be sprayed, dipped or brushed. Is RoHs-compliant and meets UL746CQMJU2, DEF-STAN 59/47(4), and IPC-CC-830.
