Summary Related to Ultrasonic Spray of Conductive Layer:
An electrochromic medium located between the first and second substrates, the medium having a light transmittance that is variable upon application of electric field thereto, applying a conductive layer on a portion of at least one of the surfaces, wherein applying the layer is accomplished at substantially atmospheric pressure, and applying at least one of metallic particles, an organometallic, a metallo-organic, and combinations thereof, wherein the conductive layer has a bulk resistivity of greater than or equal to 150 μΩ·cm. The conductive layer may be applied via ultrasonic spraying.
Solutions or inks containing nano particle based, organometallic precursor based or metallic ion based, may be selectively applied by ultrasonic spray technology. Ultrasonic spray may be used to apply solutions of copper, tungsten molybdenum, silver, gold, etc. to produce metal films with a quality similar to vacuum processes. Ultrasonic spray technology may also be utilized to apply liquid coatings such as flux, photo resist and conductive inks on various substrates with precision. Further, small auger pumps and solenoid jetting pumps attached to programmable XYZ motion control to dispense fluids in patterns, lines or dots with accuracy may be utilized. The systems may be controlled by vision monitoring and servo-driven controlled pumps attached to precision motion control equipment to dispense conductive and non-conductive materials in three dimensional shapes and patterns accurately.
