measured during manufacture in fig6 the x axis position error 40 and fig7 shows the y axis position error 42 in one embodiment the deviations are only in the micrometer range fig8 shows the rock screen exit diameter 44 fig9 shows the body outlet diameter 46 fig1 shows the inlet channel width 48 and fig1 shows the inlet channel length 50 position errors relate to the location of the feature relative to a reference feature located on the metal plate geometric features relate to the shape and dimension of the features such as the particle filter diameter the entrance outlet diameter the inlet width and the inlet length the standard deviation for the geometrical features is typically only a micrometer or less using this process which is a level or precision not previously attainable in this manner a laser manufacturing process produces an array of fluidic elements within tight manufacturing tolerances in a repetitive subtractive ablation process this allows for higher packing density for the fluidic elements the process allows for multiple fluidic elements to be manufactured at one time and in one part in one embodiment the process can manufacture 24 elements in one image field in another one can process 48 elements in one image field the process may be implemented in a bond and cut process such as that disclosed in the us patent application mentioned above where the film.
