Placing an Order for ITO Coated Glass & ITO Coated Glass Uses

First and foremost, while ordering ITO Coated glass you should clearly mention desired size, thickness, ITO resistance and quantity required to enable your supplier to give you an exact quote and keep you posted on the availability and delivery status.

ITO coated glasses are used for transparent EMC/EMI/RFI shielding applications, for circuit substrates, heater and de-icing, antennas for mobile communication, Microscope slides, display technology, so on and so forth.

 A reliable ITO coated glass supplier may offer variety of ITO coatings for EMC, anti static and heater window applications; and such coatings can be applied to polycarbonate, acrylic, glass and some types of transparent films. While supplying ITO coated glass, the distributor also mentions coating resistance that is generally known to vary between 10 ohms per square to 1000 ohms per square depending on the application. They will also provide you quote for specific applications.

Buyers looking for patterned ITO coated glasses for research purpose should specifically mention the size of order; whether they want to place a small or large order. Based on your order the manufacturer will be required to employ specialized pattern masking process to set quantities or order size. Patterns can be created either through engineering drawings or directly from data files.

While placing an order buyer should check and verify the following - ITO resistance of the glass ordered; glass type, whether it is polished or unpolished; thickness of the product ordered, standard or non standard coating specifications on the glass (buyer can check advantages and availability of range f glasses available like, high quality float glass, polished glass, Borosilicate Thin Glass etc; and maximum sheet size available in that category. While standard or smaller sizes are easily available, larger size is available on customised request. 

Buyers looking for variation like ITO coated PET film: Buyer to note that ITO coated PET film is an electro-conductive plastic film for a transparent electrode that facilitates high transparency, chemical, and thermo-stability, low moisture permeability, and is used as substrate. Sheet resistance and size etc. vary based on end user’s requirements.  

ITO Coated Glass An Overview

Indium tin oxide (ITO) is a mixture of indium (III) oxide (In2O3) and tin (IV) oxide (SnO2). When in powder form it is green-yellow in colour however when deposited as a thin film on glass it is transparent/colourless and works as a transparent electrical conductor. 

 

ITO COATED GLASS OVERVIEW

Clients focused on using transparent conductive ITO-coatings on high quality glass substrates will benefit from this article. ITO coated glasses of superior quality are electrically conductive and optically transparent. They facilitate high sheet resistance homogeneity and come with SiO2 barrier passive layer, their micro roughness is less, and offer high VIS-NIR light source transmission, etc.

ITO Coated Glass’ field of application is wide. These ITO coated glasses and slides are used in display technology, de-icing use and applications, ITO coated glass plate, flat antenna used for mobile communication, research purpose glass slides, Circuit substrate, Ito slides that can be heated, Transparent EMF/EMI/ EMC/RFI/HF shielding glass and many others. Before choosing supplier, it is for the buyer to ensure that they will be able to cater to their precise requirements.  

Though ITO coated glasses are generally available in standard sizes, they can be manufactured in customized dimensions and sizes specified by the client based on their requirement. 

Before placing an order it is for the buyer to confirm the following facts concerned with order/ as part of quotation; whether they deliver large size orders, and what would be the delivery time period and whether it suits you, will the manufacturer be willing to make them in odd sizes as and when required and if they would, how long would it take them to deliver it. Do they keep standard sizes in stock or each order is processed independently, this is important information to have if buyer is likely to place in-between order. Buyer should also check whether manufactures will offer consultation or advice if required with regard to ITO coated glass or its variations being bought from them.

If you’ve chosen a reliable supplier or manufacturer of ITO-coated glass, he will be equipped to customize your requirements; the manufacturing unit will ensure that substrate material, conductivity, optical transmission,  film thickness of the indium-tin-oxide layer or other technical properties are adapted to your technical needs. The supplier will also specify coating construction, optical transmission, refractive index, flatness, and surface quality of the glass ordered by you.

How to Maintain & Clean FTO Coated Glass

FTO Coated glass is electrically conductive, colour neutral glass, widely used in electronic and several other industries. For example it is commonly seen used in touch screen displays, thin film photovoltaic, energy-saving windows, opto-electronics, RFI/EMI shielding and several insulating applications. Before placing an order one must reconfirm the precise glass thicknesses and surface resistivity one requires. 

As far as cleaning the FTO glass is concerned, there are many different ways to do it. What works for some people, doesn’t quite work for others. We are listing down various ways that we have found and are being used to clean FTO glass. We are sharing them here as a way to provide information leaving it to you to use the one that suits you best. 

  

This is how one can safely clean FTO coated glass for electrochemical deposition.  There is a set of people who feel comfortable using the same process and material that they use for cleaning ITO coated glass, i.e. they do ultrasonic cleaning with ethanol, acetone and dry water.  On the other hand there are people who don’t prefer use of acetone to clean FTO because they feel that it is likely to adsorb onto the electrode, giving ruse to spots of non deposition.

Then there is another method where in the substrate is washed with cotton & neutral liquid detergent; followed by rinsing it thoroughly with another cotton, using enough water; again washing/rinsing it with ethanol twice in the US bath for about half a minute, concluding wash with DI water 2 times in the same bath for a half a minute each. Then dry it with nitrogen. If the FTO substrate is cut, then you have to be extra careful as there is a chance that US may break the borders and creates glass needles that may scratch your FTO, damaging the deposition.

Some people simply wash the FTO glass for half a minute in Piranha, but several who have experimented with Piranha claim that it etches FTO. 

FTO glass can also be cleaned by taking it through RCA treatment, which is a mild cleaning process and works well for both ITP as well as FTO and which helps to removes organic impurities from the surface. It is suggested to take 1: 1: 5 volume ratio of NH3, 30% H₂O₂ and H₂O; to be heated at 70-80 degree C for 15 minutes, thereafter rinsing it in DI water 3-4 times. Degreasing in hot (  ̴60⁰C) saturated KOH in isopropanol is also a sought after FTO cleaning process.
