unloading arm and receiving cassette is not aligned; wafer would get bumped on the receiver cassette and get dropped and stuck between chamber door and cassette, possibly breaking the wafer if user is not around

Unload arm moves to quickly when going from chamber to cassette.

The unload bimba cylinder is bad (leaking) will need to
be change. I adjusted the plunger on so that it does not
slammed when it unlload into the cassette, I cycled the 
tool w/out problem. Will order a new unload bimba
cylinder.

Message-ID: <mailman.333.1356281732.3883.gasonics-pcs@snf.stanford.edu>

If things are being changed with the recieving cassette would it be possible to slow down the unloader arm?  This thing seems to be on crack and slams the wafers into the cassette at high speed.  Can be a tad bit scary for valuable wafers.
