The phrase “in-line parylene processing" is deceptive because it does not accurately describe the method in which parylene (XY) is applied as a conformal coating. It is true that some aspects of the traditional production line are relevant, but primarily in a fractional way. without the traditional station-to-station regimentation of standard in-line manufacturing processes.

Conformal coating of an object occurs when an appropriate coating material is applied on-top and around an underlying substrate, to protect it from such environmental and performance concerns as chemical incursion and excess moisture. Liquid organic polymer conformal coatings – acrylic, epoxy, silicone and urethane – prevent:

Like any other renewable energy technology, electronics for solar (photovoltaic) panels are necessary for transforming, transmitting, and monitoring the system. Unfortunately, system electronics can be fragile, and frequently are the panel’s weakest link. Converting the sun’s light to electricity, solar panels have demonstrated their utility in numerous operational contexts. The basic operational unit of panels, the solar cells themselves, can be used to power small scale products like calculators, re-chargeable batteries or watches; full panels can be adapted to a range of larger level operations, like powering homes, lighting systems or water treatment plants.

High-tech electronic systems increasingly regulate automotive management functions for emissions’ controls, fuel systems, fluid monitoring, lighting, and powertrain mechanics, frequently comprised of miniaturized, multi-layer MEMS/Nano packages. Systems’ survival in hostile vehicular environments typified by condensation, corrosive fluids and vapors, excessive temperatures, humidity and prolonged UV exposure is partially assured by protective conformal coating.

A common generic name for Poly-para-xylylene, parylene forms a protective plastic film when applied to substrate surfaces. Application is achieved through a chemical vapor deposition (CVD) process in a vacuum, as a gas to targeted substrate surfaces.

Offering sensitivity and performance in a compact package, microelectromechanical systems (MEMS) have become increasingly prevalent in U.S. military applications over the last few decades and are enabling significant technological advances. As with all things military, however, robust protection of these sensitive electronics is imperative in order to ensure that they can withstand the harsh conditions often found on the battlefield. Conformal coatings such as Parylene can help MEMS-based military technologies withstand conditions such as extreme temperatures, humidity, dust/dirt, chemicals, and rugged terrain.
Military and defense equipment are put to the test and subjected to uniquely harsh conditions on a daily basis. These mission-critical products must be rugged and able to withstand extreme weather and temperatures, exposed forces of gravity that are well above and beyond normal situations, and a range of contaminants such as salt, water, and fungus. Luckily, the application of a parylene conformal coating to relevant electronics can ensure that components are fit for duty in the military and defense industries.
