Nanocoatings for Electronics

The significance of polymeric conformal coatings in safeguarding printed circuit boards (PCBs) from functional impediments like dust, corrosion, moisture, and temperature fluctuations is widely recognized. What may be less apparent is that as electrical components in PCBs shrink, conventional conformal films are proportionally less effective for certain coating purposes. With the emergence of microelectromechanical systems... Read More >>

Updates on Conformal Coating and Tin Whiskers

Electrically conductive tin whiskers, though not fully understood, are crystalline structures measuring between 1-2 mm. These structures can emerge from surfaces where tin serves as the final finish, with surfaces treated with electroplated tin being particularly prone to whisker growth. While first observed in the 1940s, a definitive solution to prevent their growth remains elusive,... Read More >>

Different Types of Parylene

Parylene, a widely used term for Poly-para-xylylene, creates a protective plastic film when coated on substrate surfaces. This coating process is carried out using chemical vapor deposition (CVD) in a vacuum environment, where the gas is applied to specific substrate surfaces. Parylene films offer remarkable versatility, protecting substrates with a reliable barrier against acids, caustic... Read More >>

Improving Patient Outcomes with Parylene-Coated Stents

Coronary and neurovascular stents are tubular medical implants that act as a supportive framework, enhancing vascular structure. They are utilized to unblock or widen arteries, aiming to increase blood flow and lower the risk of cardiac events like heart attacks. Parylene conformal coating provides critical function to these support structures. Parylene’s use on stents has... Read More >>
