How to Test Parylene Adhesion
The Need for Adhesion Testing Applied mechanical processes stimulate the binding force between surface molecules required for Parylene adhesion to substrates, which is essential to both good Parylene performance and assembly/component functionality. The emergence of conditions characterized by non-adherence and delamination squander the coating’s typically exceptional protection against chemical attack, corrosion and moisture, as well...

How to Improve Parylene Adhesion to Noble Metals
Characteristics of Noble Metals Selecting the appropriate pre-treatment procedures is a key factor to this success of Parylene adhesion to any substance. Procedures can vary and are dictated by the substrate to be coated. Chemically inert surfaces like gold, silver and other noble metals, and nonpolar thermoplastics such as Parylene, are extremely difficult to bond... Read More >>
Best Implantable Device Coating
Implantable devices place a special set of requirements and challenges on their coatings. The moisture and broad mixture of chemistries inside the body present difficult and sometimes harsh environments for long-term material survival and performance. Coatings not only need to survive and perform appropriately, they additionally need to remain non-irritating and inert enough to be... Read More >>
Coating Spotlight: SCS ALD+Parylene Multilayer Coatings
A newer technology at SCS, ALD+Parylene combines atomic layer deposition (ALD) coatings with Parylene to form an enhanced multilayer coating that offers increased barrier properties to protect devices in extreme environments. Multilayer coatings are stacked structures that alternate different layers of organic and inorganic thin films. ALD films can be made of numerous inorganic materials,... Read More >>

Ruggedizing UAV Electronics with Parylene
Unmanned aerial vehicles (UAVs) are aircraft piloted by remote control or onboard computers. They are an integral element of unmanned aircraft systems (UAS) which consists of three basic components: the UAV, a ground-based controller and a system of communications between the two. Also called drones, UAVs are often used for military missions. The electronic assemblies... Read More >>
What’s the Best Coating for MEMS?
Microelectromechanical systems (MEMS) encompass technologies with operational components sized between 1-100 micrometers. The miniaturization of MEMS devices and structures, including their mechanical and electro-mechanical elements, is a direct result of advancements in adapted semiconductor fabrication technologies initially employed for electronics. MEMS are primarily defined by mechanical functionality, regardless of the components’ physical mobility within their... Read More >>
