Abstract

Disclosed is a method of cleaning printed circuit boards in the vertical position. The primary advantage of this concept include a greater cleaning potential than what is currently available. Specific improvements using this new method include the ability to clean both sides of the printed circuit board simultaneously, the capability of cleaning printed circuit boards of different sizes and reduced maintenance.

Aqueous Cleaning Vertical Method

      Disclosed is a method of cleaning printed circuit boards
in the vertical position.  The primary advantage of this concept
include a greater cleaning potential than what is currently
available.  Specific improvements using this new method include the
ability to clean both sides of the printed circuit board
simultaneously, the capability of cleaning printed circuit boards of
different sizes and reduced maintenance.

      Transportation of the printed circuit board through the cleaner
is accomplished with a belt drive supported by a bar between the
drive sprockets to prevent sagging of the drive belt with guide rails
or wheels for vertical support of the bottom edge of the printed
circuit board.  The top edge of the printed circuit board is
supported by a similar guide rail and drive system. The top drive is
adjustable up and down for different size printed circuit boards.
Other mechanical drives can be used for this transportation through
the cleaner (Figs. 1 and 2).

      Spray bars are mounted in either a vertical or horizontal
position to both sides of the printed circuit board.  Universal ball
headers are mounted in spray bars and jet spray headers are mounted
in the universal ball headers for adjustability and control of spray
direction.  This individual control of spray heads will allow
compound angle, shear spray, action in four directions (all sides of
mounted components are covered) eliminating shadowing.  Gr...
