Used for aerospace. automotive, commercial, defense, industrial and medical applications, conformal coatings are applied in film layers generally 30-130 microns (micrometers/μm) thick, or 0.0012-0.0051 inches (“). Conformal films’ exceptional thinness is their greatest asset. Coatings safeguard printed circuit boards (PCBs) and similar electronics from performance malfunction generated by unwanted contact with:

Available in five basic material types, conformal coatings can be readily adapted as protective, insulating films for electronics. However, there can be some confusion about which type is best-suited for a specific use. Clearly defining the performance parameters for the component[s] to-be-coated helps coordinate the conformal film material with a unit’s functional requirements. Accurate assessment of environmental conditions like anticipated levels of corrosion, contact with foreign particulates, expected concentrations of moisture/salt spray, temperature fluctuations and vibrational range determine which coating type is best-suited to your electronics’ applications. Without appropriate protection, printed circuit boards (PCBs) and similar electronics will not survive harsh environments, and malfunction.

Appropriately selected and applied, conformal coatings provide essential working protection for printed circuit boards (PCBs). However, removal of conformal coatings is necessary if the wrong coating material is selected relative to the PCB’s functional requirements, inadequately supporting its operating environment. Poor coating application can trigger failure mechanisms within the assembly, also calling for its removal and re-application.

Printed circuit boards (PCBs) electrically connect and power all but the simplest electronic products. To function as designed, PCBs and their components – capacitors, resistors, etc. – require protection against operating problems caused by corrosive liquids, dust, physical shock, temperature extremes and, in the case of medical implants, bodily fluids. Conformal coatings are applied over PCBs to safeguard mechanisms and maintain functionality.

Parylene and urethane conformal coatings share many characteristics. Both are physically strong, resistant to chemicals and mitigate tin whisker formation. This doesn't mean that the two compounds are interchangeable, though. While parylene offers a unique blend of capabilities, many projects choose urethane because of its cost, strength and other advantages.
