Coating theory
WebConformal coating is a protective coating applied to printed circuit boards and other electronic components to protect them from moisture, dust, corrosion, and other environmental factors. It is a thin, protective layer … WebDec 3, 2024 · The so-called Landau–Levich–Deryaguin problem treats the coating flow dynamics of a thin viscous liquid film entrained by a moving solid surface. In this context, we use a simple experimental set-up consisting of a partially immersed rotating disc in a liquid tank to study the role of inertia, and also curvature, on liquid entrainment.
