Drilling D263 Thin Glass – D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um); Drilling to +/-0.02 mm hole position. No minimum order; DFM review included with every RFQ.
We drill D263 Thin Glass daily, in thicknesses from 0.1 – 30 mm. The controlling numbers: +/-0.02 mm hole position working tolerance, 0.15 mm laser / 0.5 mm mechanical minimum features, and exit-chip controlled below 0.1 mm off the machine. Where the drawing asks for more, downstream lapping and polishing take over.

Manufacturing capability
The core strength of Drilling is through-holes, blind holes and countersinks at densities beyond 1,000 holes per part. The honest limit: hole-to-edge distance should stay above 1.5x thickness to protect strength. Both belong on the drawing before quoting, not after.
One material, many routes: on D263 Thin Glass we also quote laser cutting, double-side polishing, etching, cnc machining, and multi-step drawings are the norm rather than the exception.
DFM notes from the shop floor
The shop-floor rules that matter here:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- Process boundary: hole-to-edge distance should stay above 1.5x thickness to protect strength.
- 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.

Buyer questions, answered
What tolerances are achievable on D263 Thin Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
What thickness range do you stock for D263 Thin Glass?
Standard stock spans 0.03 – 1.1 mm, with blanks up to 440 x 360 mm. Other formats are sourced per order.
How does D263 Thin Glass behave under heat?
CTE is 7.2 x 10^-6 /K and continuous service reaches 400 C (Tg 557 C), which is what drives its use where down-drawn fire-polished surfaces matters.
What accuracy does drilling hold?
+/-0.02 mm hole position with minimum features of 0.15 mm laser / 0.5 mm mechanical. Hole-to-edge distance should stay above 1.5x thickness to protect strength.
