Dear All,

We have a confusion about conformal coating area. Our quality department rejects some boards because edges of some high components were not coated. These edges are non-conductive and I think there is no need to coat non-conductive areas. IPC-A-610 10.5.2 says that "Conformal coatings should be transparent, uniform in color and consistency and uniform cover the board and components".

1.       Does it mean we have to coat all areas unless specified in design document?

2.       Is there any requirement to coat non-conductive areas?

3.       Do we have to coat non-conductive areas of components?


Thanks.

Best Regards
