Device for at least three-stage cleaning by cleaning, rinsing and drying of substantially flat objects

摘要

The circuit boards are [5] are located in the space between a pair of cleaning and drying units [6]. In the first operation cleaning fluid is pumped from reservoirs [11,12] through a valve to nozzles [8] on the rotating units. A second operation uses rinsing fluid and a final stage uses compressed air [13] for drying the surfaces.
