Abstract

An attack of chlorofluorocarbons on the earth's ozone layer has prompted immediate reduction and elimination plans for the use of FREON* in IBM. These reduction and elimination plans include the replacement of FREON base part cleaners with alternative methods of cleaning. One popular alternative solvent being used in IBM is deionized water. In most cases, IBM is using an aqueous parts cleaner with deionized water and clean hot air to wash and dry parts. A basket has been designed from results of experimentation on cleaning and drying head and arm assembly parts in an aqueous cleaner. This basket is designed to be used in an aqueous parts cleaner with a material-handling system and open-face cleaning/drying tanks.

Basket for Proper Orientation of Parts in Cleaning Tanks

      An attack of chlorofluorocarbons on the earth's ozone
layer has prompted immediate reduction and elimination plans for the
use of FREON* in IBM.  These reduction and elimination plans include
the replacement of FREON base part cleaners with alternative methods
of cleaning.  One popular alternative solvent being used in IBM is
deionized water. In most cases, IBM is using an aqueous parts cleaner
with deionized water and clean hot air to wash and dry parts.  A
basket has been designed from results of experimentation on cleaning
and drying head and arm assembly parts in an aqueous cleaner.  This
basket is designed to be used in an aqueous parts cleaner with a
material-handling system and open-face cleaning/drying tanks.  The
angle of the trays in the basket and the orientation of the parts in
the trays are crucial in maximizing cleaning and drying of the parts
during the cleaning cycle.

      The three governing factors in the design of the size and shape
of this basket are the size of the cleaner tanks, the material
handling system, and the parts which are washed in the cleaner.

      The size of the smallest tank in the cleaner and the type of
pickup used on the material-handling system dictates the actual
outside dimensions and shape of the basket. After these dimensions
have been determined, a decision on the number and the positioning of
the parts within the basket can be made.  The parts w...
