Embedded single board computers are often needed for harsh environments.
Industrial, military and airborne applications often expose boards to corrosive conditions including humidity, salt spray, fungus and other contaminants. Conformal coating, a protective material applied over electronic circuitry, can prevent short circuits, corrosion, dendritic growth and electro-migration of metals between conductors.
Conformal coating from Ampro is applied by spraying, dipping or flow-coating the circuit board assembly. This coating is typically three mils (0,003") thick. Ampro generally uses HumiSeal 1B31 acrylic coating, although epoxy urethane, paraxylylene and silicone-based coatings are also available upon request. Acrylic coatings are fast drying and offer high moisture resistance, excellent flexibility and superior dielectric properties. The coating is also easy to repair, making it extremely useful in a wide variety of high performance situations. HumiSeal 1B31 contains a UV safety tracer for ease of inspection under a blacklight.
The conformal coating is a seven-step process: preparation, where the separable parts are removed and cleaned; surface treatment, using a low frequency plasma gas to etch the solder mask and improve adhesion; masking of all interface mating surfaces, mounting holes, fans and heatsinks according to Ampro's detailed specifications; spray coating of boards and thickness coupons using state-of-the-art spray guns and booths; curing, where boards are cured per manufacturers' specifications. Some cures are thermal, with temperatures not to exceed 65°C; inspection, where coating thickness is verified on the coupons and board coverage is verified using a blacklight; and finally testing, where previously removed parts are re-installed and the boards are fully tested.
