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 double-side polishing, dicing, edge grinding, polishing, 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 equipment runs the drilling work?
Diamond core drills, ultrasonic assist and laser percussion heads.
Is there a minimum order for drilling d263 thin 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.
