Win2uit will help protect your valuable, finished electronics assemblies with expertly applied conformal coatings.
A conformal coating material is a thin, protective barrier that shields sensitive electronic components. Typically applied at 25-250 μm (micrometers) it is applied to electronic circuitry to protect them from harsh environments that may contain moisture, debris, or chemical contaminants. If a board is uncoated (non-protected), environmental conditions can damage the electronics and cause failure.
Conformal coating also provides a barrier to air-borne contaminants from the operating environment (such as salt-spray) thus preventing corrosion. Conformal coatings are also breathable – the coating layer protects against many environmental hazards, but also allows any moisture trapped in the coated circuit board to escape.
In most cases, Win2uit Electronics uses Humiseal® 1B73, a single component, fast drying acrylic conformal coating. HumiSeal 1B73 demonstrates excellent flexibility and electrical properties, fluoresces under UV light so we can easily inspect it, and is easily repaired. HumiSeal 1B73 coating is MIL-I-46058C qualified, IPC-CC-830 and RoHS Directive 2011/65/EU compliant, and recognized under UL File Number E105698.
