I have incresed the time to 320 seconds From amyers at snf.stanford.edu Tue Apr 20 10:46:19 2004 From: amyers at snf.stanford.edu (amyers at snf.stanford.edu) Date: Tue, 20 Apr 2004 10:46:19 -0700 Subject: Problem wbdiff 2004-04-20 10:46:18: spin dryer not drying all that well Message-ID: 4" DRYER NOT DOING ITS JOB From crichter at snf.stanford.edu Tue Apr 20 18:25:56 2004 From: crichter at snf.stanford.edu (crichter at snf.stanford.edu) Date: Tue, 20 Apr 2004 18:25:56 -0700 Subject: Problem wbdiff 2004-04-20 18:25:55: Spin Rinse Dryer Does not Dry Wafers Message-ID: From mdickey at snf.stanford.edu Wed Apr 21 06:53:39 2004 From: mdickey at snf.stanford.edu (mdickey at snf.stanford.edu) Date: Wed, 21 Apr 2004 06:53:39 -0700 Subject: Problem wbdiff 2004-04-20 18:25:55: Spin Rinse Dryer Does not Dry Wafers Message-ID: Adjusted dry time #2 to 210. It dryed the wafers fine.

I repeated the cycle again and it worked ok, but the heating indicator light does not light up during the drying cycle.

The program worked sucessfully without interruption. The dryer is still a little noisy and vibrates a little more than what I have seen in the past....perhaps the rotors needs balancing? I dried my wafers after this test and had no problems.
