Test & ProbeLTX-Credence ASL 1000 family
Research Quality: 60% complete

The LTX / Credence ASL 1000 is an integrated-circuit tester. The LTX / Credence ASL 1000 is typically configured with an Electroglas EG 4090 and 4090 u+ prober handling 8-inch wafers. Configurations of the LTX / Credence ASL 1000 include an 8-inch hot chuck and a standard board set with gold.[1][2][3]

What it is

The LTX-Credence ASL 1000 is an IC tester.[1][2][3][9][4]

How it works

The ASL 1000 can be used with a wafer prober in probe-based test setups.[1][2][3][9]

Where it fits in the process flow

General reference — not yet source-verified

An IC tester is placed in the semiconductor verification flow before package-level qualification and shipment.

Applications

The ASL 1000 is used for semiconductor integrated circuit test and wafer probe evaluation.[1][2][3][9]
