The Electroglas EG 4090 X is a prober.[1]
What it is
How it works
General reference — not yet source-verifiedA wafer prober positions a semiconductor wafer under probing hardware so electrical measurements can be made on selected sites.
A prober class machine typically combines wafer handling, precision positioning, and probe contact to support device-level electrical test before further processing or packaging.
Where it fits in the process flow
General reference — not yet source-verifiedA wafer prober is used in the test flow where electrical contact to devices on a wafer is needed before downstream assembly or final test activities.
A probe step supports wafer-level evaluation so devices can be measured and screened while they remain on the wafer.
Applications
General reference — not yet source-verifiedA wafer prober is used for semiconductor device testing at the wafer stage.
A wafer prober supports electrical probe contact for integrated circuits and other wafer-fabricated devices.
