Gorilla Glass Wafers

Gorilla glass is manufactured by Corning and as a standard, comes unstrengthened chemically. The glass is an alkali-aluminosilicate thin sheet glass, that through its composition allows a deeper layer of chemical strengthening than has been previously possible with other chemically strengthened glasses. Gorilla glass may not be chemically strengthened prior to fabricating the final size required, as it will fracture. However, once the final size is diced, polished or otherwise machined, the glass may be strengthened using an ion exchange process.

The ion exchange process is performed by placing the glass in a hot bath of molten salt at approximately 400 degrees C. This causes smaller sodium ions to leave the glass, while larger potassium ions from the salt bath replace them. As the glass cools, the larger potassium ions are pressed together, forming a layer of compressive stress on the glass. By design, the composition of Gorilla glass allows for a deeper layer of absorption of the potassium ions, thereby creating a high compressive stress level deep into the glass.

Surface finish is standard transparent 60/40 scratch/dig.  Flatness is 3-5 waves/inch.  Valley can also lap and polish Gorilla Glass to improve the surface finish and flatness.  Valley can also dice Gorilla Glass to any die size from as small as 0.127mm square.

NOTE: If chemical strengthening is required, please advise at time of quotation. Standard Gorilla glass comes unstrengthened, as it must be machined to final size prior to chemical strengthening.
