What are the common problems when using three anti-paint?

During the use of the three-proof paint, due to technological problems, the following phenomena will occur: Bubbles: Large bubbles, small bubbles, or both large and small bubbles appear at the same time. Whiteness: the coating film contains water or other liquid, the color of the coating film is lighter than the original, and the coating film is white mist. Delamination: three anti-paint layered phenomenon, mainly in the components and group welding layer. Orange lines: the scene of orange lines in the three-proof paint is caused by forced drying. Cracks and scratches: cracks in the three-proof paint are mainly due to excessive thickness of the film, where the surface tension is too large such as the edges of the pins and components. Capillary phenomenon: small spacing tube leg connector during board design; Too harsh coating requirements; The viscosity of the three-proof paint is too low; The flow rate of the three-proof paint is too large; The surface tension between the substrate and the three-proof paint is inappropriate.
