Quick answer: Soda-Lime Glass for LED Packaging covers Soda-Lime Glass (CTE 9.0 x 10^-6 /K, 360 nm – 2.0 um). Prototypes ship in 5-10 working days.
What soda-lime 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. Soda-Lime Glass is the fit here because it offers lowest cost per square meter.

Getting the drawing right
Three items decide most of the cost and lead time on this work:
- Material note: higher CTE means edge chips propagate under thermal load, so edge finishing quality drives reliability.
- 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.

Buyer questions, answered
How does Soda-Lime Glass behave under heat?
CTE is 9.0 x 10^-6 /K and continuous service reaches 350 C continuous, which is what drives its use where lowest cost per square meter 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 soda-lime 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.
