ULTRASONIC THIN FILM COATING VS OTHER COATING TECHNOLOGIES

DEPOSITION METHOD	PRESSURE SPRAY/ AIR ATOMIZATION	DIP COATING	JETTING	SCREEN PRINTING/BLADE	SPUTTERING	CHEMICAL VAPOR DEPOSITION (CVD)	ULTRASONIC SPRAY
HOW IT WORKS	Liquid is forced through a very small orifice under high pressure	Substrate is dipped into material	Similar to a home office inkjet printer, ejecting tiny drops	Spreading a paste with a blade over a substrate	Ejecting particles from a target by bombardment with high energy particles	Creates a reaction between gases over a substrate, which condense on its surface	High frequency sound waves create mechanical vibrations, forming droplets with very little kinetic energy
DISADVANTAGES COMPARED TO ULTRASONIC SPRAY	● High velocity spray bounces off substrate, wasting material ● Prone to clogging, high maintenance ● Poor repeatability over time	● Long drying times ● Cannot create thin films ● Requires large amount of material, large amount of waste	● Uneven dispensing ● Poor tolerance to abrasive chemicals ● Prone to clogging, high maintenance	● Requires minimum viscosity ● Poor uniformity on very thin coatings ● Requires large amount of material	● Very expensive ● Poor transfer efficiency ● Slow batch process	● Expensive to scale up ● Very high operating expenses ● Poor material usage	ADVANTAGES ● Uniform drop sizes ● Operates with small amount of material ● Does not clog ● Easily scalable ● Environmentally friendly
