Many chemicals found in the oil, gas, and petrochemical industries can consign electronic
components to a short life, creating high failure rates and low reliability. Corrosive agents such as H2S gas,
hydrocarbons, chlorobenzene, and chemical by-products play havoc with components that control and manage processes,
or transport vital data between control centers and remote sites. What is required is a protective coating that can
isolate the components from the harsh reality of industrial settings.
Conformal coatings, as the name suggests, do just that by conforming to the contours of elements
that populate printed circuit boards (PCBs) and other components present in electronic assemblies and systems.
Conformal coatings are thin layers of synthetic resins or organic polymers applied to PCBs and electronic
components for protection against environmental, mechanical, electrical, and chemical problems including
contaminants such as dust, dirt, fungus, moisture, chemicals, thermo mechanical stress, mechanical shock, and
vibration. Conformal coating types include urethane, silicone, acrylics, epoxies, and parylene.
A conformal coating service from AbraxSys is offered to protect all internal PCBs and components from dust,
moisture, fungus, corrosion and vibration. The coating can be brushed or sprayed onto the PCB, depending on
application needs. A conformal coating can help minimize electromigration between metal conductors. In addition,
the use of a conformal coating can protect circuits and components from direct contact that can lead to abrasions
or electrical short circuits.
Solution for Preventing Corrosion and Moisture
Coating offers protection of circuitry from moisture, fungus, dust and corrosion caused by
Coating prevents damage from board handling during construction, installation and use, and
reduces mechanical stress on components and protects from thermal shock.
Coating resists abrasion in service.
Coating enhances performance and allows greater component density due to increased dielectric
strength between conductors.For more information please Contact
