Aerospace Conformal Coatings

Posted by Sean Horn on Fri, Feb 09, 2018 @ 08:05 AM

Conformal coatings composed of acrylic, silicone and parylene polymer materials are valuable for a wide range of aerospace applications, which can push technologies to their limits. Applied to printed circuit boards (PCBs) and related electrical assemblies, conformal coatings maintain device performance through difficult operational conditions. The presence of atmospheric variation, chemicals, humidity, mobile ion permeation, moisture, temperature fluctuation, or excessive vibration can generate:

Conformal Coating Types: Acrylic, Urethane, Silicone, and Parylene

Posted by Sean Horn on Fri, Feb 02, 2018 @ 07:33 AM

Used for aerospace. automotive, commercial, defense, industrial and medical applications, conformal coatings are applied in film layers generally 30-130 microns (micrometers/μm) thick, or 0.0012-0.0051 inches (“). Conformal films’ exceptional thinness is their greatest asset. Coatings safeguard printed circuit boards (PCBs) and similar electronics from performance malfunction generated by unwanted contact with:

Ruggedization and Conformal Coating

Posted by Sean Horn on Fri, Jan 05, 2018 @ 07:35 AM

Conformal coatings are non-conductive dielectric film-coverings applied over printed circuit boards (PCBs) to protect them from damage caused by chemical incursion, corrosion, current-leakage, dirt/dust, extreme temperatures, fungus, moisture, rain, salt-spray, wind and persistent, intensive vibrations both within and external to the device. These failure mechanisms can soon lead to PCB malfunction and eventual breakdown. Rugged coatings’ exceptional performance durability and versatility protect delicate, finely-tuned components.

Best Electronics Coatings

Posted by Sean Horn on Fri, Nov 17, 2017 @ 08:01 AM

Available in five basic material types, conformal coatings can be readily adapted as protective, insulating films for electronics. However, there can be some confusion about which type is best-suited for a specific use. Clearly defining the performance parameters for the component[s] to-be-coated helps coordinate the conformal film material with a unit’s functional requirements. Accurate assessment of environmental conditions like anticipated levels of corrosion, contact with foreign particulates, expected concentrations of moisture/salt spray, temperature fluctuations and vibrational range determine which coating type is best-suited to your electronics’ applications. Without appropriate protection, printed circuit boards (PCBs) and similar electronics will not survive harsh environments, and malfunction.

How to Remove Conformal Coatings

Posted by Sean Horn on Fri, Aug 18, 2017 @ 07:30 AM

Appropriately selected and applied, conformal coatings provide essential working protection for printed circuit boards (PCBs). However, removal of conformal coatings is necessary if the wrong coating material is selected relative to the PCB’s functional requirements, inadequately supporting its operating environment. Poor coating application can trigger failure mechanisms within the assembly, also calling for its removal and re-application.

3 Key Properties of Acrylic Conformal Coating

Posted by Sean Horn on Fri, Aug 04, 2017 @ 07:39 AM

Conformal coatings made of acrylic resin (AR) are very popular, because of their distinctive beneficial properties. They protect printed circuit boards (PCBs) and similar electronics from corrosion, dirt, dust, fungus, moisture, and thermal shocks. Exceptionally user-friendly, liquid AR can be simply applied by brush, dip, or manual/robotic spray, generally resulting in the fastest turnaround-time of all conformal coatings. Ease of application and rework generates low cost for both manufacturer and client. AR’s moisture protection is also very highly rated, adding to its utility for a wide range of coating uses.

Conformal Coating for PCB's

Posted by Sean Horn on Fri, Jul 21, 2017 @ 07:47 AM

Printed circuit boards (PCBs) electrically connect and power all but the simplest electronic products.  To function as designed, PCBs and their components – capacitors, resistors, etc. – require protection against operating problems caused by corrosive liquids, dust, physical shock, temperature extremes and, in the case of medical implants, bodily fluids.  Conformal coatings are applied over PCBs to safeguard mechanisms and maintain functionality.
