ITO Coating Soda-Lime Glass – Soda-Lime Glass (CTE 9.0 x 10^-6 /K, 360 nm – 2.0 um); 5 – 500 ohm/sq, >85% visible transmission. No minimum order; DFM review included with every RFQ.
ito coating soda-lime glass is indium tin oxide transparent conductor applied by magnetron sputtering, laser patterning option. On Soda-Lime Glass it adds a patternable transparent electrode layer – the specification we run to is 5 – 500 ohm/sq, >85% visible transmission.

Specification advice
Before sending the RFQ, check these against your drawing:
- Material note: higher CTE means edge chips propagate under thermal load, so edge finishing quality drives reliability.
- 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.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
What the process holds
Beyond this page, Soda-Lime Glass routinely runs through cnc machining, lapping, edge grinding, coring in our shop – most real parts combine two or three of these steps.
Who orders this
ito coating soda-lime glass shows up across led packaging (groove covers, phosphor carriers, package windows); industrial displays (touch covers, gauge windows, printed bezels). Background reading on the underlying material science: ASTM C1036 flat glass standard.

Buyer questions, answered
Is there a minimum order for ito coating soda-lime 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.
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
