Conformal Coatings for LED Applications
Conformal coatings elevate the performance of LEDs. Whether it’s enhancing color accuracy, providing protection against damage, or ensuring optimal electronic performance, conformal coating extends the applicability of LED technology. Discover the top six ways in which conformal coating and LEDs complement each other seamlessly. 1. UV Resistance Many types of LEDs are sensitive to the... Read More >>
Elongation Properties of Parylene
For conformal coatings, elongation is a measure of material ductility — a specific coating’s ability to undergo significant plastic deformation before rupture. A coating’s yield elongation is the maximum stress the material will sustain before fracture. Thus, computed Parylene elongation measurements represent the total quantity of strain the conformal film can withstand before failure. While... Read More >>
Comparing Lubricious Coatings
Selection of conformal coatings for medical devices takes into account a host of considerations including the operational environment it will encounter when employed. Additional operational/performance factors can also include the chemical, electrical and mechanical compatibility between the coating and the device, and the temperature variation the device is expected to encounter. Equally important in many... Read More >>
Parylene for Military Sensors
Security systems rely on different types of advanced, intelligent and connected sensor technologies. Application areas are diverse, including radar systems, vision, night vision (IR-cameras), acceleration/ orientation/location detection (accelerometers, gyroscopes, GPS), chemicals (neural toxins, other toxic gases, liquids), wearable sensors (temperature, humidity, location detection), barometric (under water), air flow (aerospace, munitions), and they are brought together...

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 >>
