Removing Conformal Coatings

Posted by Sean Horn on Fri, Feb 21, 2020

Conformal coatings provide a long-term, stable and reliable encapsulation method for the electronic components from the environmental effects. Different industries and service conditions calls for different protective coatings. In some cases, changes in the requirements or mistakes would call for action to remove the coating. While some coating materials are easily removed, some are virtually [&he

Polyurethane Conformal Coatings: When To Consider An Alternative

Posted by Sean Horn on Fri, Feb 7, 2020

Polyurethanes (Urethane Resin- UR) are polymeric, flexible, insulating, hard and chemically resistant (Acid—Alkali—Salty water) conformal coatings that are used to protect electronic parts from chemical corrosion, oil, moisture, fungus, and static discharges. Polyurethane coatings are supplied as single or two-component formulas. These coatings are suitable for printed circuit board applicatio

Parylene C Conformal Coating: Optical Properties, Refractive Index and Application Areas

Posted by Sean Horn on Fri, Jan 31, 2020

Parylene films are highly employed in different applications because they are chemically inert, transparent in the visible range of the solar spectrum, offer high dielectric strength and insulation resistance, low moisture vapor transmission and gas permeability rates [1]. They can also be deposited as void-free layers on complex geometries in deep, narrow crevices.
