Plating process enhanced by squeegee roller apparatus

Abstract

An improved apparatus for treating plate-like work pieces with a designated chemical solution, including printed circuit boards, including (1) a tank for holding the chemicals, agitation frame and roller assembly, (2) a frame that holds two rollers covered in brush or sponge like material, (3) a guide rail assembly attached to a roller frame, (4) a slotted block attached to a guide rail (5) a disk with a bottom shaft coupling and top pin to move slotted block, (6) a low rpm motor that attaches to disk coupling.

1 . An apparatus for treating plate-like work pieces with a designated chemical solution. Including printed circuit boards, said apparatus comprising: 
 A tank for holding said chemicals, an agitation frame with roller assembly, said tank having an open top which is configured to receive said work piece when said work piece is oriented so that its largest-surface area is oriented vertically.    
   
   
       2 . An apparatus as recited in  claim 1 , further comprising: 
 A clamping device for electrical connection and aligning work piece surface.    
   
   
       3 . An apparatus as cited in  claim 1  further comprising a roller brush assembly configured to travel between said work piece.  
   
   
       4 . An apparatus cited in  claim 3 , that further includes a roller core that is conductive and acts as an anode for producing an electric field.  
   
   
       5 . An apparatus as cited in  claim 3 , wherein said roller brush assembly is attached to a guide rail that is moveable and allows travel back and forth.  
   
   
       6 . An apparatus as cited in  claim 5 , wherein a guide rail is attached to a slotted block that rides between a pin.  
   
   
       7 . An apparatus as cited in  claim 6 , wherein a circular disk with a pivot pin is mounted on top coupled to a low rpm adjustable motor to drive slotted block and rail assembly.
