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 can be Coated: Conformal Coatings and Parylene Compared

Posted by Sean Horn on Fri, Mar 23, 2018

Conformal coatings are used to protect printed circuit boards (PCBs) from dust, humidity/moisture, mildew/mold, temperature extremes, and other elements whose prolonged contact might interfere with assembly function. Coatings also enhance electrical clearance-tolerance, while safeguarding PCB components from contamination (particulate or otherwise), corrosive materials, and mechanical stress.

Brush Application of Conformal Coating

Posted by Sean Horn on Fri, Mar 2, 2018

Conformal coatings’ functional value stems from their ability to safeguard printed circuit boards (PCBs) and similar electronics from external threats to their performance. Composed of acrylic, epoxy, silicone and urethane polymer resin, coatings also provide layers of insulative protection. These liquid coatings are applied to PCBs by wet methods, primarily by brush, dipping (component immersio
