Parylene and Hydrofluoric Acid

Posted by Sean Horn on Fri, Sep 18, 2020

Parylene is a chemically inert conformal coating [1]. It has a well-established chemical vapor deposition process and patterning methods. It is a great candidate for use in various application areas (health, aerospace, oil and gas, microelectronics, and so on.) due to its mechanical, physical, optical and chemical properties. Parylene is known to withstand highly corrosive […]

What Types of Materials can be Parylene Coated?

At Diamond MT we often get the question: “Can my xxx be parylene coated?”  The number of substrate surfaces that can be coated with parylene is plenty. In the table below a number of industrial applications that using Parylene conformal coatings are listed. The examples can be extended.

How Long Will 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 […]
