Abstract: A pin assembly for lifting and supporting substrates according to the invention comprises a roller glide for a lift pin with rollers reducing the friction of the vertical pin movement, a ball bearing sole plate with elastic suspension for re-centering the sole plate after one coating cycle and a ball-bearing pin head that lowers the friction between the pin and the substrate and minimizes lateral forces that the substrate can apply on the pin.

Abstract: The method of the invention establishes a reference state and a current state for an industrial evolutionary process from physical parameters measured on all the equipment items employing the evaluating process. These two states are compared, parameter by parameter, by resorting to fuzzy logic for classifying the quantities, and a diagnosis is established using expert rules.
