Three Things to Look for in Conformal Coating Services
A variety of conformal coatings – acrylic, epoxy, silicone, urethane and Parylene — assure proper insulation for PCBs. Such environmental conditions as contamination from debris, humidity, solvent incursion or the impact of human handling are minimized by conformal protection, reducing performance degradation and prolonging assembly life. Materials and Methods The material-specific performance properties of conformal... Read More >>
What Solvent Breaks Down Parylene?
While Parylene provides a reliable, versatile conformal coating, it can require removal. When circumstances necessitate removal of liquid coatings – acrylic, epoxy, silicone or urethane – a wide range of chemical solvents can be used to detach the film from the underlying substrate. Solvent processes are commonly used as they cause minimal harm to printed... Read More >>
Rugged Devices and Parylene
Designed for use under the most extreme and severe conditions, rugged products must function reliably in harsh environments of extreme temperatures, intensive vibrations and disproportionate levels of dryness or moisture. Because use of rugged products are unusual, internal components of these specialized products are also subject to frequently unremitting challenges to function and performance. These... Read More >>
Parylene C Conformal Coating: Optical Properties, Refractive Index and Application Areas
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. Parylene C... Read More >>
Typical Conformal Coatings Use
Different conformal coatings have a wide range of uses throughout many different industries. While originally applied within the electronics industry, conformal coatings many benefits have led to its use in many other fields, most notably medical, aerospace and defense and automotive. Medical While all conformal coating types can be used for different applications, Parylene is the... Read More >>
Nonconformity of Parylene on Wafers
The polymer Parylene (XY) provides exemplary, ultra-thin conformal coating for printed circuit boards (PCBs), solar cells, light emitting diodes (LEDs), medical implants, aeronautical/military equipment and numerous other products, with uniform, insulative protection in the nanometer range. One of XY’s basic advantages is its reliable coating uniformity, exceeding that of liquid materials like acrylic, epoxy, silicone... Read More >>
Things to Consider when Choosing a Parylene Coating Service Provider
The Parylene coating industry is a fairly niche business, but it is still a competitive market. However, the few top-quality providers are relatively easy to identify. Here are some of the attributes that you should actively seek when searching for a Parylene conformal coating provider: Liquid Coating Capabilities While it might seem counterintuitive, look for...

What Temperature is Parylene Applied at?
Parylene (XY) conformal coatings are applied to substrate materials through a specialized vapor deposition polymerization (VDP) process that completely eliminates the liquid phase of wet coatings. In addition, no initiators or catalysts are involved in VDP, which results in truly conformal protective films. This is in stark contrast to wet coating materials such as acrylic,... Read More >>
Conformal Coating Types: Acrylic, Urethane, Silicone and Parylene
Conformal coatings, utilized in aerospace, automotive, commercial, defense, industrial, and medical sectors, are applied as thin film layers typically ranging from 5 to 130 microns or 0.0002 to 0.0051 inches. Their remarkable thinness is a key attribute. These coatings protect printed circuit boards (PCBs) and other electronics from operational issues caused by unintended contact with:... Read More >>
Can I Solder Through Parylene?
Parylene: Properties and Processes Conformal coatings are applied to printed circuit boards (PCBs) and other sensitive electronics to protect their components and electrical function. Parylene conformal coatings provide these assemblies superb security from electrostatic discharge, and additional performance advantages, including: These characteristics are adaptable to a wide range of as aerospace, defense, automotive, consumer, industrial...
