Problem with conformal coating

2017/2/27 22:48:10

I use conformal coating DYMAX #984-LVUF and I don't know if it's a problem of viscosity but 0805 components are not covered properly. We use a dispensor to applied it and we cured it by UV. Even if I apply a thicker layer, the coating seems to have problem to stick correctly to the top corners of the components. So if we apply water on top of the component, we can see that the coating do not cover the component correctly.
Is someone ever had this problem and what do you suggest to do?
