IPC-TR-587 technical report delivers results of a major study on conformal coating. In most manufacturing specifications, conformal coating thickness is defined as the thickness of the final polymer film on a flat, unencumbered surface of the assembly, however conformal coating thickness on other assembly and component surfaces is not characterized.

IPC-TR-587 is a report outlining an IPC study of major conformal coating types, coating application techniques, and coating cure technologies, characterizing the final film thickness on common component surfaces.
