Quick answer: Dicing FTO Coated Glass covers FTO Coated Glass (CTE substrate dependent, 80 – 82% visible @ 7 ohm/sq); Dicing to +/-0.01 mm index accuracy. Prototypes ship in 5-10 working days.
We dice FTO Coated Glass daily, in thicknesses from 0.05 – 3 mm. The controlling numbers: +/-0.01 mm index accuracy working tolerance, 30 um kerf minimum features, and edge chipping under 15 um off the machine. Where the drawing asks for more, downstream lapping and polishing take over.

Capabilities and limits
The core strength of Dicing is singulating wafers into dies with tight index accuracy and low chipping. The honest limit: straight-line cuts only; contours route to laser cutting instead. Both belong on the drawing before quoting, not after.
One material, many routes: on FTO Coated Glass we also quote edge grinding, drilling, cnc machining, coring, and multi-step drawings are the norm rather than the exception.
Specification advice
Three items decide most of the cost and lead time on this work:
- Material note: the harder FTO film abrades diamond tooling faster and edges need post-cut inspection for film lift.
- 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.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Who orders this
The recurring buyers of dicing fto coated glass: laboratory instruments (cuvettes, sight glasses, stir-cell windows); industrial displays (touch covers, gauge windows, printed bezels); semiconductor equipment (view ports, wafer carriers, plasma rings, chamber windows). Background reading on the underlying material science: ScienceDirect: FTO glass.
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.

Buyer questions, answered
What equipment runs the dicing work?
Automatic dicing saws with resin and metal-bond blades.
Is there a minimum order for dicing fto 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.
