Servo amps AU6356N2 (a.k.a EESA-001A1 / 2-VC-16396-2 / 2-39-53462) and AU3575N223 (a.k.a. EESA-001 / 2-39-48133-GSRPR) are sitting in a fully functional track, ready to be pulled and sent to you when you need it. In DNS 80B tracks, these electronic modules control the spin of a wafer in the coating and developing processes. The common failure mode is loss of LED indication on the connection panel and erratic or non existent motor control. GetSpares.com keeps these modules installed in fully operational tracks in their warehouse inventory, so you know they are working. When you order a module, it’s pulled from the track and shipped.
