Welcome to PF.

What kind of coating? What material? How thick? What purity? The more information that you can give us, the better we can help you.

If you are looking to just rent some time on an evaporator, a small one starts around $300 per hour, plus training.

Thanks a lot for your replies. I am looking for the most economical method of ito coating on glass/acrylic surface in a uniform way. The thickness of the glass surface will be 3-5mm, and we will using this project for making heating plates from 35 degree Celcius to 120 degree Celcius.

Any insight will be very helpful

From what I understand, you can't beat sputter deposition for consistent ultra-thin coatings...

...assuming your coating can indeed be 'sputtered', of course. What type of coating are you using?

ito coating on glass/acrylic surface in a uniform way.

"ito" = Indium/Tin/Oxide. A semi-transparent metallic coating often used for RF shielding on instrument faceplates, and as a resistive heating element.

Here in the U.S.A, there are service companies that are usually hired to do the coating. It is done in a vacuum and requires some rather expensive equipment and experience.

Maybe there is a large University nearby that has the equipment or knows where it can be done.

I just typed ito coating into Google and found many results.

Please let us know what you decide on doing.

Cheers,

1. How do I prepare the glass-like substrate for the nano coating deposition?

Before depositing a nano coating on a glass-like substrate, it is important to clean the surface thoroughly to remove any dust, oils, or other contaminants. This can be done through a series of solvent cleaning, ultrasonic cleaning, and/or plasma cleaning processes. It is also recommended to use a primer or adhesion promoter to improve the coating's adhesion to the substrate.

2. What type of nano coating is best for glass-like substrates?

The best type of nano coating for glass-like substrates depends on the specific application and desired properties. Some popular options include hydrophobic coatings, anti-reflective coatings, and self-cleaning coatings. It is important to consider factors such as durability, transparency, and chemical resistance when selecting a coating.

3. What equipment is needed for depositing a nano coating on a glass-like substrate?

The equipment needed for depositing a nano coating on a glass-like substrate typically includes a vacuum chamber, a source for the coating material (e.g. sputtering target or evaporation source), and a power source for the deposition process. Additional equipment such as a substrate holder, gas flow control, and a deposition monitor may also be necessary.

4. What are the key parameters to control during the nano coating deposition process?

The key parameters to control during the nano coating deposition process include the substrate temperature, deposition rate, gas flow rate, and pressure within the vacuum chamber. These parameters can greatly affect the properties and quality of the coating, so it is important to carefully monitor and adjust them as needed.

5. How can I ensure uniformity and thickness control of the nano coating on the glass-like substrate?

To ensure uniformity and thickness control of the nano coating on the glass-like substrate, it is important to have a well-designed deposition process and equipment. This may include using a rotating substrate holder, controlling the deposition rate and gas flow, and monitoring the coating thickness in real-time. Additionally, post-deposition analysis techniques such as profilometry can be used to verify the coating's thickness and uniformity.
