Ruggedized products are conceived for use in severe conditions, environments where excessive moisture or dryness, extreme temperatures, high levels of vibration, wind, or lack of atmosphere are the rule.   Internal components of these specialized products require the same degree of ruggedization as exteriors. 

Parylene Removal, Rework, and Repair

Parylene's benefits as a conformal coating are well known. It resists heat, cold, moisture, and pressure; salt spray, electricity, and solvents can't permeate it. And while these attributes of parylene contribute to the conformal coating's appeal, they also present distinct challenges, particularly in regards to parylene removal, rework, and repair.

Since its discovery in the 1940s, Parylene has skyrocketed to prominence as an ideal conformal coating choice for a range of applications. Given its unique blend of properties, it might seem like an unparalleled conformal coating option. In many ways, it is. Here are five key properties of Parylene that differentiate it from the rest.

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.

Parylene Adhesion to Noble Metals

Parylene adhesion can be tricky to manage. Unlike other coatings that adhere to the surfaces they coat, parylene sticks to itself. This can cause trouble when it needs to be applied to smooth surfaces, like areas made of stainless steel or noble metals like gold or silver. However, since parylene has so many other advantages, it's worth looking into methods to improve adhesion. You can use the product; you just might need an extra step.

Parylene and Tin Whiskers

Tin whiskers have long been a frustrating occurrence for those manufacturing and using electronic devices. First discovered in the 1940s, the whiskering of metal has been the cause of serious problems including the damaging of vital and difficult to replace equipment. Finding ways to prevent or slow the growth of whiskers has been a focus of engineers and scientists for quite some time.

Parylene conformal coatings are used in many different industries. With their hardness, chemical inertness and ability to perfectly coat any surface, they have expanded well beyond their original military and aerospace applications. Whether it's a protective coating for an LED or a protective shell around a coronary artery stent, the compound is found in places where you might not expect to find it.

Parylene is proving to be an ideal material for sealing, insulating, and protecting electronic modules, devices, and circuit boards. It’s easy to apply, goes down in uniform layers, and stands up to many environmental hazards. These same properties also make Parylene an excellent choice for manufacturing micro-electromechanical systems (MEMS) – sensors, actuators, and structures forged from silicon using industry standard semiconductor-processing techniques. In fact, Parylene is helping MEMS designers overcome some of their toughest challenges, clearing the way for new features and functions and a fresh growth spurt for MEMS applications.
