Conformal coatings have been used in aerospace, automotive, electronics, medical device and military industries for many years for a variety of surface modification functions, including:
- Isolate/protect device surfaces from the environments to be encountered
- Provide thermal and electrical insulation – selectively or overall
- Improve lubricity… or conversely, reduce tackiness
- Stabilize/consolidate surfaces by micro-particle immobilization
- Reduce/eliminate surface micro-porosity to control the entrapment of contaminants
- Stabilize very delicate micro structures
- Function as an interface that is non-inhibitory to tissue growth
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.
Parylene deposition takes place in an evacuated, room temperature chamber through a process known as vapor deposition polymerization (VDP). Sometimes also identified as CVD, this process involves the spontaneous polymerization of a conformal coating onto all exposed substrate surfaces, edges, and into crevices at a predictable rate, with thickness controllable from 500 angstroms to 75 microns.
This webinar will focus on the Parylene’s unique properties, how the coating is applied, examples of applications that benefit from Parylene’s properties, and advances that have been made in adhesion technologies. As materials and applications continue to advance, Parylene coatings are increasingly being used to enhance the reliability of today’s, and tomorrow’s, innovative technologies.
