PWM101 Light-duty Spinner

Spins standard 4" diameter silicon or ceramic substrates or smaller diameters or pieces, at speeds up to 4000 rpm. Due to the absence of a chemical drain, foil is used to contain the extra resist. Thus, the foil must be changed after each use in order to correctly identify the resist for proper disposal.
