What is the Service Life of Parylene?

Posted by Sean Horn on Fri, Sep 25, 2020 @ 08:00 AM

Under ambient conditions (room temperature, in air) Parylene is a lifetime conformal coating. The exposure to environmental stressors like temperature, oxygen, UV-light and chemicals can degrade the lifetime especially when two or more are existent at the same time.

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

Posted by Sean Horn on Fri, Jan 31, 2020 @ 08:00 AM

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.

4 Aerospace Applications of Parylene

Posted by Sean Horn on Fri, Nov 03, 2017 @ 07:49 AM

Superior to liquid coatings like acrylic, epoxy, silicone and urethane, parylene conformal films offer unparalleled protection for aerospace printed circuit boards (PCBs) and related electronic assemblies. Their complete encapsulation conforms entirely to all device surfaces – flat, round, creviced or edged, while adding almost no weight to the covered device.

UV-Cure Touchup and Parylene Coating

Posted by Sean Horn on Fri, Mar 25, 2016 @ 07:39 AM

A photochemical process used to preserve conformal coatings, adhesives, and inks, UV curing generates a variety of value-added properties in comparison to conventional curing techniques.  Applying high-intensity UV light to dry (cure) coatings or other substances, UV curing can provide instant results, increasing production speed while reducing the need for and number of typical set-up and clean-up processes.  Lowered operating costs and increased production capacity are further advantages of UV curing for many coating materials and processes.

LED Lifespan as Effected by UV Light

Although LEDS are designed to provide as many as 100,000 hours of illumination under laboratory conditions, they are not nearly as resilient when subjected to persistent real-world, real-time usage.  Sensitive to electrical interference, moisture, UV light, and other persistent sources of physical damage, LEDs require protection to operate at levels anywhere near maximum efficiency.  Of all the conformal coatings available to deliver reliable safeguards on an ongoing basis, none surpasses parylene.
