ABSTRACT:
A method and apparatus for forming rows and columns of closely spaced micron sized holes in a thin foil, including a cylindrical member and means for rotating it. There are means for mounting a plurality of axially extending foil strips on the cylindrical member and means for moving said foil strips axially of the cylinder. There are a plurality of stationary lasers uniformly positioned in a single plane about the periphery of said cylindrical member and means for correlating movement of said cylindrical member, axial movement of the foil strips and the firing of said lasers so as to form holes as described in closely spaced rows and columns.
