PAX
The LTX-Credence PAX is a semiconductor tester in the test and probe category. The PAX tester includes modules such as SSBA, OVI, HCOVI, AWG_HSB, DIG_HB, DDP_PIN, DDP_SEQ, and XRF.[1][2]
What it is
How it works
General reference — not yet source-verifiedA test and probe system evaluates semiconductor devices by making electrical contact through probes and routing signals through test instrumentation.
A tester in this class commonly supports measurement, signal generation, and device interfacing so that devices can be exercised under controlled test conditions.
Where it fits in the process flow
General reference — not yet source-verifiedA test and probe system sits in wafer test and device characterization flows before final packaging or downstream assembly steps.
A tester in this class is used where electrical verification, probing, and measurement are needed to sort, characterize, or validate devices at the wafer level.
