Expander Ring

An expander ring, also known as a wafer expander ring, is widely used in semiconductor and LED chip manufacturing. It consists of an inner ring and an outer ring designed to securely hold and support the wafer during the expansion process.

The expander ring fixes the wafer in place, allowing controlled expansion after dicing. This helps create uniform spacing between individual chips, improving picking efficiency and reducing the risk of damage during subsequent handling.

Available in a variety of specifications and sizes, expander rings can be customized to meet different wafer diameters and process requirements. Engineered for precision, stability, and cleanroom compatibility, they provide reliable performance for advanced semiconductor and LED production applications.
