Dow Intros Solventless Silicone Conformal Coating
Midland, MI — Dow has introduced its new DOWSIL™ CC-8030 UV and moisture dual-cure conformal coating, a solventless silicone conformal coating with an ultraviolet (UV) and moisture dual-cure system for high throughput. This environmentally responsible silicone
technology promotes sustainability, health and safety, while reducing processing costs through automated spraying and fast, energy-efficient UV curing. Other silicones support UV curing, but none are conformal coatings with a low enough vis- cosity for spray coating and with a secondary mois- ture cure for shadowed areas. The new DOWSIL product also offers more
reliable protection against stress and thermal cycling, versus competitive materials. The material is an environmen-
tally progressive solution for protect- ing rigid PCBs, sensitive electronic components and fine-pitch designs from environments with airborne con- taminants. This high-performance sili- cone conformal coating is formulated without benzene, toluene, ethylben- zene, or xylene (BTEX) solvents. DOWSIL CC-8030 can be ap -
plied in multiple layers. When com- pared with acrylated urethane UV- cure coatings, the new silicone-based material provides superior protection against thermal cycling. A soft, medium-viscosity silicone, CC-8030 has a rheology that is
Cohu Intros LiDAR Optical Test and Inspection Solution
Poway, CA — Cohu has introduced a complete solution for the test and inspection of LiDAR devices. According to Yole Développement, the LiDAR market is expected to grow at a 29 percent CAGR to $6 bil- lion by 2024, driven by advanced driver assistance systems (ADAS) and applications in lane assist and emergency braking in semi- and fully autonomous vehicles. The integrated solution on
Cohu’s NY32W platform was initial- ly developed to bring new LiDAR laser transmitters to market. The NY32W is a fully automat- ic optical testing, visual inspection
designed for high-throughput spray coating. Its dual-cure technology combines speed with complete-
ness of coverage for reduced work-in-process inven- tory. With UV curing from a standard mercury broad spectrum lamp at 300 mW/cm2, the coating is tack-free after less than ten seconds. Compared to thermal ovens that cure in min-
utes, UV ovens are also smaller and consume less energy. Further, the new coating’s secondary alkoxy moisture curing reaches any shadowed areas where UV light cannot penetrate, or UV cur- ing is otherwise incomplete. Moisture curing also supports thicker coating and will not add stress
from thermal cycling. Contact: The Dow Chemical Company, 2211
