Bill: OSP coatings can certainly by applied without the use of 
conveyorized processing. You can use free standing tanks with vertical 
immmersion. It would be similar to a manual black oxide line. Generically the 
process would be; soak clean,rinse,microetch,rinse,OSP,rinse,dry.	     
    	The biggest problem you could be faced with is how to handle small 
parts. Since the coating is typically applied as a final step after route, 
unless the parts are large, panelized or in a carrier they are difficult to 
process as individual small pieces using vertical slotted racks.
