  • Patent number: 4323327
    Abstract: Method and apparatus for aligning a pair of planar templates on opposite sides of a planar board. The apparatus includes a pivotable open-book structure having a pair of surfaces which intersect at an inclined interior edge substantially paralleling the structure's pivot axis. Projecting from each of the surfaces, adjacent the lower edges thereof, is a pin for aligning matching edges in a board and template supported on the associated surface. When the structure is pivoted, an aligned board and template combination placed against one surface in the apparatus is flipped from that one to the other surface, exposing the other side of the board. The method of the invention proposes first, cradling a board and a template placed against one side of the board, with such cradling producing alignment of the two. The aligned board and template are flipped to expose the other side of the board.

  • Patent number: 4189820
    Abstract: A method for enabling simple, reverse-side alignment of a pair of templates for electrical circuit patterns which are to be placed on the opposite sides of a double-sided printed circuit board. The method proposes, first, placing the templates for such patterns in pattern-aligned, confronting relationship, followed by trimming of a pair of intersecting margins in the templates to produce an angle of intersection therebetween which matches the angle of intersection of a pair of selected edges in such a board. The trimmed templates are then fitted on opposite sides of the board, with the templates' trimmed edges flush with the board's selected edges.
