How Can You Validate Parylene Coverage?

Posted by Sean Horn on Fri, May 15, 2020

Parylene XY is a transparent, thin (hundreds of nanometers to a few micrometers), well adhering, pin-hole and defect free conformal coating. They are coated uniformly on flat surfaces and component configurations with sharp edges, points, flat surfaces, crevices or exposed internal surfaces are coated uniformly without voids.

Conformal Coatings for Oil & Gas Sensors

Posted by Sean Horn on Fri, May 8, 2020

Oil & Gas industry makes use of sensors which face extremely high temperature and high pressure (HTHP) environments as in downhole drilling (>200°C and 30 kspi). In US natural gas supply lie in reservoirs below 15,000 ft. Wells at these depths pose environmental challenges of drilling due to the temperature, pressure and gasses. Increasing the […]

What Happens to Parylene when the Dielectric Voltage is Exceeded?

Posted by Sean Horn on Fri, Apr 24, 2020

Poly(para-xylylene) derivatives (parylenes) are used as conformal coatings in a wide range of applications in the automotive, medical, electronics, military and semiconductor industries. They are inert, transparent and have excellent barrier properties as dielectric thin films. Because their deposition takes placeunder vacuum sub-micron range crevices can be coated leading to excellent barrier pro
