When it comes to reworking, parylene's strengths are also its biggest drawbacks. In addition to its ability to comprehensively coat substrates, it is also, by design, very challenging to remove. However, "very challenging" and impossible are two different things. Furthermore, good planning strategy before coating can also help to reduce the need for parylene rework.Read More
Parylene conformal coatings have protected medical device components with an extended range of applications for over 40 years. They offer both patients and medical personnel the most reliable level of uniform, biocompatible device-security for cardio- logical and surgical procedures. Their value and application proliferate, as technology develops.
Organic Polymers used as Coatings
The overall generic name parylene designates a unique set of organic polymeric coating materials with innumerable applications. All commercially applied parylene configurations are polycrystalline and linear in nature.Read More
In the course of our business applying parylene to a range of different products, our clients ask many questions. They also have a few consistent misconceptions. Here are the five biggest ones -- and the facts to clear things up.Read More
Parylene has a well-deserved reputation as one of the leading choices for conformal coatings. For many applications, it is the best choice. However, there are some real parylene disadvantages, as well. For many applications, other conformal coatings such as acrylic, epoxy, silicone or urethane offer better performance, lower cost or both.Read More
As engineers continue to seek out the most powerful technologies packed into the smallest footprints possible, the use of microelectromechanical systems (MEMS) are on the rise. At the forefront of progress in miniaturization, MEMS enable small form factors without sacrificing precision and reliability. In many cases, MEMS technologies even offer an increase in performance over their larger, traditional counterparts. MEMS technologies can also be produced at low cost, owing to the use of semiconductor fabrication methods.Read More
Parylene and It's UsesRead More
What is Parylene?
Parylene is a conformal protective polymer used for coating, first postulated by Michael Szwarc in 1947. His early experiments involved the decomposition of the solvent p-xylene. His worked proved that when the vapors of the p-xylene reacted with iodine, para-xylyene di-iodide was the only resulting product. The reaction produced only a low yield and the process was later made more efficient by William F. Gorham.Read More
Regardless of the variant, Parylene in general garners a great deal of praise for the many advantages it offers as a protective conformal coating for applications as varied as medical, aerospace, defense, LEDs, and automotive. Chief among the coating’s benefits, however, is that it can withstand common sterilization techniques, such as electron beam (e-beam), gamma, ethylene oxide (EtO), and autoclave.
Like many chemicals, para-xylylene actually comes in several common variants:
- N. The most basic type of the compound is highly elastic and, as such, is very good at penetrating small areas on components.
- C. The C variant of the chemical replaces one aromatic hydrogen component with a chlorine atom. It is less elastic and is extremely popular in medical applications, in part due to its high degree of moisture resistance.
For contemporary industrial uses, sensors collect and respond to analog information, transforming it to a digital format. Sensor design for many uses has increasingly relied on microelectromechanical systems (MEMS) technology. MEMS are semiconductor-made micro-mechanisms, which typically work by deflecting optical signals from input-to-output fibers by deploying movable micro-mirrors. They demonstrate virtually unlimited potential for an exceptional range of rapidly evolving products for information technology (IT), telecommunications, consumer electronics and automotive engines, among many other purposes.Read More
