Applied as a conformal coating through a unique chemical vapor deposition (CVD) process, parylene provides micron-thin, resilient barrier protection for an exceptional range of electrical assemblies. In comparison to liquid coatings — acrylic, epoxy, silicon, urethane — parylene is the coating-of-choice for protecting printed circuits boards (PCBs) and medical devices. It’s films
The parylenes consist of a range of para-xylylene polymers whose desirable physical and electrical properties support expansive utilization as conformal coatings for electronic and medical devices Parylene films are applied to substrates via a chemical vapor deposition (CVD) process, which deposits monomeric parylene vapor homogeneously and deeply into the surface of printed circuit boards (PCBs

Perhaps the most reliable of the conformal coatings, parylene (para-xylylene di-iodide) is also one of the more expensive coating options. Production costs typically encompass three primary expense categories — raw materials, labor, and lot volume. Of the three, labor expenses are generally the most costly, but raw materials can add significantly to production overhead; materials’ [&he
