Yes, 200 rpm per second, not thousands. A slow acceleration helps the material spread a little more evenly. Clif Clifford J.

Are you suggesting an > acceleration or is it just a mistake? When you program a newer model of spinner, you can set the acceleration in addition to the rotational speed. For example, an MTI Flexifab take takes the acceleration in krpm/s. --Kirt Williams Agilent Technologies _______________________________________________ mems-talk@memsnet.org mailing list: to unsubscribe or change your list options, visit http://mail.mems-exchange.org/mailman/listinfo/mems-talk Hosted by the MEMS Exchange, providers of MEMS processing services.
