LTX-Credence
ASL 1000
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]
