Quick answer: D263 Thin Glass for LED Packaging covers D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um). Prototypes ship in 5-10 working days.
What d263 thin glass for led packaging actually buys from a glass shop: groove covers, phosphor carriers, package windows. The requirement underneath is diced covers with etched cavities and printed dams. D263 Thin Glass is the fit here because it offers down-drawn fire-polished surfaces.

Getting the drawing right
Before sending the RFQ, check these against your drawing:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- 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.
Capabilities and limits
One material, many routes: on D263 Thin Glass we also quote dicing, edge grinding, polishing, cnc machining, and multi-step drawings are the norm rather than the exception.
Application context
d263 thin glass for led packaging shows up across led packaging (groove covers, phosphor carriers, package windows); medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); microfluidic devices (chips, manifolds, via plates, bonded stacks).

Frequently asked questions
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 do led packaging programs usually order?
Groove covers, phosphor carriers, package windows. Typical spec: dice to +/-0.02 mm, cavity depth +/-5 um.
Is there a minimum order for d263 thin glass for led packaging?
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.
