What it is

The Sonix pulse2 is a pulser/receiver used in Sonix automated wafer inspection systems for LED inspection. The Sonix pulse2 improves signal-to-noise ratio and gain for clean, clear imaging at any frequency and depth.[1][3][2]

How it works

The Sonix pulse2 functions as a pulser/receiver within an ultrasonic wafer inspection setup. The Sonix pulse2 improves signal-to-noise ratio and gain to support clean, clear imaging across different inspection frequencies and depths.[1][3]

Where it fits in the process flow

General reference — not yet source-verified

Ultrasonic wafer and die inspection typically sits after bonding or other structure-forming steps and before later assembly or packaging decisions. The method is used as a screening and analysis stage to separate defective material, support yield improvement, and feed defect information back to the manufacturing process.

Applications

General reference — not yet source-verified

Ultrasonic inspection in semiconductor and related device manufacturing is used where internal defects can affect reliability, assembly success, or electrical performance. Common targets include bonded structures, layered devices, and dies or packages where subsurface integrity matters as much as visible surface condition.
