May I add another 2 eurocents worth? It will also depend on how the coating is applied. If sprayed, edge coating is uncontrolled, unless specific measures are taken. If dipped liquid or paraxylylene, it is inevitable, unless masked, an extra operation. If liquid dipped, a very slow controlled withdrawal speed is essential to prevent an accumulation along the bottom edge. In the case of punched or other rough edges, an advantage of deliberate coating is that it will reduce the risk of loose fibres floating around the housing in its lifetime. This may be important if there are fine mechanics exposed to them. Doug, I'll respond to your other message, possibly within a day or so; I'm ultra-occupied today as I have family coming.
