As devices and components become smaller and increasingly complex, they present unique challenges for many conformal coatings. Poly(para-xylylene), better known as Parylene, is an ultra-thin, inert, transparent coating that meets these challenges. Parylene provides highly useful dielectric and barrier properties per unit thickness, as well as extreme chemical inertness and freedom from pinholes. The coating is also biocompatible. Parylene protects components and devices, including circuit card assemblies, MEMS, sensors, LEDs, cores, lab-on-a-chip devices, pacemakers, stents, and cochlear implants, to name only a few.
