Webinar – Conformal Coatings- Application & Best Practice Optical Microscopy Inspection Methods

June 9, 2021 @ 11:00 am - 12:00 pm

FREE Webinar

High reliability electronic assemblies and sub-systems require protection from the effects of moisture and corrosive contaminants that are ever present in the environment by which they are expected to perform. Methods to protect critical electronics include sealed dry nitrogen filled shelters, enclosure environment control (humidity & temperature) and the use of various conformal coating chemistries.

While conformal coatings do NOT provide a hermetic seal from the environment, they are utilized to provide a hydrophobic moisture barrier that significantly reduces moisture absorption over time. Conformal coatings comprised of Polyurethane, Epoxy, Acrylic, Silicones & Poly-Para-Xylene (Parylene), have material advantages & disadvantages based on cost, process and the level of desired environmental protection. Material property selection factors include ease of application, rework, uniformity of coverage, dielectric isolation, moisture, chemical, fungal and resistance to UV exposure breakdown.

Topics Covered-

– Background and overview of various conformal coatings
– Characteristics, advantages and challenges of coatings and methods
– Other techniques which utilize custom Chemical Vapor Deposition (CVD) processes.
– Review an example of a sub-assembly Acrylic conformal coating Inspection process
– Use of UV Tracers and best practice optical inspection techniques used confirm conformal coat uniformity and coverage
