Jean-Francois,

IPC-CC-830 is a materials qualification document, not a application or 
performance specification.  It sets the minimum criteria for coatings to 
be used in high performance electronics. 

IPC-A-610 and IPC-J-STD-001 both have coating sections, but both defer to 
the engineering drawing or print.  Essentially, the coating goes where the 
drawing says and coating does not go where the drawing specifies a keep 
out zone.  Required clearance depends on the drawing and the quality 
system of the customer.

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?
