摘要： A support table supports a module board during a screen printing thereof. The support table has a body in which rectangular grooves are formed in both upper and lower surfaces thereof, a plurality of slots formed in a middle portion thereof and open to the grooves, and a plurality of jigs which are inserted into the slots and fixed relative to the body. The jigs can compensate for any difference between the heights of semiconductor devices which are mounted on the board, and support the board, with the board or the semiconductor devices resting directly on the jigs as the manufacture process at that time requires. The screen printing method includes steps of (a) preparing the support table by inserting appropriate ones of the jigs in the slots of the body of the support table; (b) disposing a board, having a plurality of land patterns formed thereon, on the support table; (c) positioning a screen, which has hole patterns formed therein, over the board with the hole patterns aligned with the land patterns of the board; and (d) forcing lead material through the hole patterns of the screen and onto the land patterns of the board with a squeegee while the board is supported by the upper surface of the support table.
