What ITO/FTO sheet resistances are available?

Standard steps are 5-7, 7-10, 10-15, 15-20, 30-60 and 100 ohm/sq, with custom values on request. Lower sheet resistance generally means a thicker conductive film and slightly lower transmittance.

What glass thickness and transmittance can I expect?

Standard substrate thicknesses include 0.4, 0.55, 0.7, 1.1 and 2.0 mm. Transmittance at 550 nm is typically at or above 85%, and you can specify an 80/85/90% minimum in the builder.

Can you etch a custom electrode pattern?

Yes. Patterns can be laser- or wet-etched to a customer drawing, with edge deletion and typical pattern resolution around ±50 µm.

ITO Coating Glass – Custom Precision Glass Machining

ITO Coating Glass – 5 – 500 ohm/sq, >85% visible transmission. No minimum order; DFM review included with every RFQ.

ito coating glass is indium tin oxide transparent conductor applied by magnetron sputtering, laser patterning option. On the substrate you specify it adds a patternable transparent electrode layer – the specification we run to is 5 – 500 ohm/sq, >85% visible transmission.

Design guidance

Three items decide most of the cost and lead time on this work:

Sequence matters: all machining happens before ito coating; post-coating rework is not economical.
Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.

The full rules live in our tolerance design guide and holes and edges design guide.

Frequently asked questions

Do parts ship with inspection data?

Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.

What does ito coating add?

Adds a patternable transparent electrode layer. Applied by magnetron sputtering, laser patterning option to 5 – 500 ohm/sq, >85% visible transmission.

Is there a minimum order for ito coating glass?

No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.

How fast can prototypes ship?

Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.

What files do you need for a quote?

A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
