There are two main standards commonly used to initially determine if a conformal coating may be suited to harsh military and industrial applications, IPC-CC-830C and MIL-I-46058C. The main goal of these standards is to impart confidence in the users that the coatings will have a consistent quality, physical characteristics, and protection capability needed for modern electronics.
Though MIL-I-46058C has been inactive since 1998, it is still often used for electronic conformal coatings for new applications. Having picked up the torch left by MIL-I-46058C, IPC-CC-830C has continued to evolve taking into account new application requirements and technologies. One key area that IPC-CC-830C has advanced is qualification testing approaches for ultra-thin (UT) conformal coatings that are less than 12 microns thick. SignalSeal is such a coating, with typically application thicknesses around one micron.
As of the latest IPC-CC-830 standards release (revision C released in 2019) GVD has submitted SignalSeal for qualification, to add the latest IPC standards to the long list of military and industrial standards that SignalSeal already exceeds. The recent results have been in full compliance with IPC-CC-830C standards for UT conformal coatings. These standards tests include dielectric withstand voltage, moisture resistance, thermal shock, fungus resistance, and more.
These qualifications join SignalSeal’s other successfully passed testing, including hours of salt fog, temperature cycling, and 85C/85% relative humidity testing.
