A support apparatus for a through-hole soldered circuit board for use with circuit board lead trimmer of the type having a planarly-movable cutting head and a base plate below the cutting head parallel to the head's plane of movement, the setup of which can be changed rapidly and with little probability of error by a low-skilled operator. The apparatus comprises a perimeter frame of uniform height, affixed rigidly and hermetically in a planar configuration by its base to the ferromagnetic base plate of the lead trimming machine; a plurality of equal-height support posts or rods, each having a board-support apex and a magnetic base perpendicular to its associated post; a support post positioning plate, the lower surface of which is drilled with a series of holes, the centers of which correspond to planar, unpopulated regions, free of conductive traces, on the populated side of a circuit board to be trimmed; and a circuit board support plate having a cut-out which is smaller, but proportionally similar to the profile of the board to be lead trimmed. The support posts are inserted into the holes in the positioning plate from its lower surface, each support post being retained in its respective positioning plate hole by its magnetized base.
