Dicing ITO Coated Glass: ITO Coated Glass (CTE substrate dependent, >85% visible @ 100 ohm/sq); Dicing to +/-0.01 mm index accuracy. Single-piece prototypes to production volumes, quoted from your drawing.
The combination of ITO Coated Glass and Dicing comes up constantly in RFQs for a reason – the material offers laser-patternable electrode layouts, and Dicing is the right way to get accurate geometry into it. Expect +/-0.01 mm index accuracy and edge chipping under 15 um.

Design guidance
The shop-floor rules that matter here:
- Material note: machining happens film-side-aware: scribing, edge deletion and contact zones are defined before cutting.
- Process boundary: straight-line cuts only; contours route to laser cutting instead.
- 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.
Process window
Dicing earns its place through singulating wafers into dies with tight index accuracy and low chipping. Its boundary condition – straight-line cuts only; contours route to laser cutting instead – is the first thing our DFM review checks.
Beyond this page, ITO Coated Glass routinely runs through coring, drilling, laser cutting in our shop – most real parts combine two or three of these steps.

Common questions
What equipment runs the dicing work?
Automatic dicing saws with resin and metal-bond blades.
Is there a minimum order for dicing ito coated 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.
