Tabletop Coating System for Solar Cell Manufacturing
A fully enclosed XYZ tabletop ultrasonic spraying system designed for depositing solutions, suspensions, and nanosuspensions. Applications include carbon nanotube coatings, organic polymer coatings (inert option available), TCO, dopants, anti-reflective coatings as well as various thin film coatings such as CIGS, amorphous silicon and quantum dots.
Ideal for R&D or low-volume production, the ExactaCoat SC is easily configured with Sono-Tek ultrasonic nozzles to customize spray patterns for your specific application. Spray patterns range from 0.08 - 2" wide (2 - 50 mm).
The ExactaCoat sC features:
- Precise substrate uniformity with repeatability down to ±2%
- Compact benchtop design that favors portability
- 400 mm x 400 mm x 100 mm (15.75" x 15.75" x 3.94") range of motion
- Windows®-based programming software with image import
- Remote trackball teach pendant
- Coordinated motion in all three axes simultaneously
Sono-Tek ultrasonic nozzles feature:
- Highly homogenous coatings resulting in greater cell efficiency
- Up to 80% reduction in material consumption
- Non-clogging design results in minimal servicing and downtime
- Repeatable spray patterns that are easily shaped for precise coating applications
- Highly controllable spray produces consistent results with or without masking
- Corrosion-resistant titanium and stainless steel construction
- No moving parts to wear out
Operating Principle
The Impact System combines Sono-Tek's unique ultrasonic atomizing nozzle with a controlled jet of air from the flat jet air deflector.
The ultrasonically produced spray at the atomizing surface is immediately entrained in the air stream, creating a fan-shaped spray pattern (10-50mm). The velocity of the air stream is controllable, allowing low or high-impact of the atomized spray onto the product or substrate.
The AccuMist™ system combines Sono-Tek's unique Microspray ultrasonic atomizing nozzle with low pressure air to produce a soft, highly focused beam of small spray drops.
Compressed air, typically at 1 psi, is introduced into the diffusion chamber of the air shroud, which produces a uniformly distributed flow of air around the nozzle stem.
The ultrasonically produced spray at the tip of the stem is immediately entrained in the low pressure air stream. An adjustable focusing mechanism on the air shroud allows complete control of spray width (2mm - 10mm).
The spray envelope is bow-shaped. The width of the bow is controlled by moving the focus-adjust mechanism in and out.
