    It's the resulting thickness when 1 oz of copper is pressed flat and spread evenly over a one square foot area. This equals 1.37 mils (1.37 thousandths of an inch). Of course not everyone thinks in mils so please refer to the chart below to convert into your preferred unit of measure. Most PCBs are constructed with 1 oz copper thickness.How a Thickener Works,Jul 13, 2016· The machine is so called because the thickening mechanism is driven by means of a traction wheel which travels around the periphery of the tank on a rail. The mechanism, which is slowly carried around the tank as the traction wheel travels, consists of a truss to which are attached the raking blades which sweep the floor of the tank.
