Mobile electronics are damaged or killed by liquid Liquid threats are everywhere splashes, drops Events are common, and often catastrophic

Conventional Conformal Coatings
A conformal coating d f l ti does not protect from a t t tf simple spill. Electrical leakages occur from connection p points where they were p p y purposely not y coated.
Problems: Masking around connectors H t entrapment Heat t t Changes form factor (packaging of product) VOC pollution
An Advanced Coating Technology
A room-temperature, vapor deposited, textured ceramic coating with superior anti-wetting and anti-corrosion protection for Printed Circuit Boards.
IST's RepellixTM coating creates a barrier film that protects the circuit board from water damage.

The Film Properties
Base Layer Substrate S b t t
Confusion often exist between wetting (hydrophobicity), moisture and corrosion. Definitions:
Hydrophobicity: liquid surface tension (wetting) Moisture: gaseous permeability through media Corrosion: electro-chemical reaction between a material and its environment.
Corrosion often a result of moisture
Example: Installation at Customer Site
Cola Sugar Water t=0 0
CA (gas) = <10o CA (water) = >160o
Sample is completely immersed
t= 10 days
CA (gas) = <10o CA (water) = 155o
Sample is completely immersed
Cost of protecting a cellphone board is approximately 20 cents 2 minutes of talk time 1% of the perceived value ($20) 0.1% of the replacement cost ($200) 30 seconds of call center time
