EVG Spraycoater- Shutdown: System will not power up. Identified a bad 24 volt DC power supply
in the mainswitch unit, used in the EMO/interlock circuit. Replacement power supply installed on
Friday(1/25). System power up successful. Submitted request to EVG for new keycode(1/25)
KSCoat -Problem: Robot wafer pickup at load station. OK to process 4" wafers. Re-taught
Left and Right load stations for 3", 6" and 8" wafers. Need to test system operation
EVAlign- Problem: Intermittent joystick issue. New joystick received on 12/14. Installed
new joystick. Still a drift in "X" direction. FSE advises to adjust Null voltage for joystick. Should
be 2.5vdc +/- .1. Voltage is currently at 4.5vdc.
EVG-Imprint - Shutdown: Top optics are not initializing. Possible bad "Y axis" servo controller. Need
to isolate problem to "Y servo" controller. EVG F/S has the servo motor controller for testing.
Litho SRD- Its been 6 weeks with no wafer breakage. Continuing to monitor closely
Resolved Issues
