Long used to safeguard printed circuit boards (PCBs) and other essential automotive electronics from harsh operating environments, conformal coatings’ importance in auto-design/manufacture has never been greater. Fragile electronic components and the paths between them require protection for PCBs to perform reliably. Conforming to PCBs’ topographies, coatings insulate assembly components, safe
Selecting a suitable conformal material for coating printed circuit boards (PCBs), related electronics, or other devices requires recognition of each coating type’s unique combination of benefits and drawbacks. These must be considered in relation to a given application.

Accidentally discovered in 1947, by chemist Michael Szwarc, the polymer parylene originally bore his name, and was known for a brief period known as Szwarcite. Working to thermally decompose the solvent p-xylene at temperatures exceeding 1000 °C, Szwarc identified the monomer para-xylylene di-iodide as the only product resulting when para-xylylene was reacted with iodine.
