How Long Does Parylene Coating Last?

Posted by Sean Horn on Fri, May 22, 2020

The stability and insulation property of parylene conformal coating is critical for the reliable operation of electronic devices throughout their lifetime (PCBs, MEMS, sensors, implants and so on.). The failure mechanism of the conformal coating layers is known to be due to pore formation, blistering, delamination and thinning or pinhole formation due to dielectric breakage […]

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
