You can use the guidelines of IPC 610 but quite often it's up to the
engineering drawing to define the keep-out areas. Our rule of thumb is to
coat the whole board unless otherwise specified.

Not per IPC-CC-830 or IPC-HDBK-830, but quite often there will be keep-out
areas along the edges for card guides and/or thermal and electrical contact.

Hi Technetters,

 

Can anyone tell me if there is a spec on the coverage of conformal coating,
more precisely is there a required clearance on the edges of the PCBs?
