Abstract
A locator pin is provided as part of an apparatus for maintaining accurate registration between a circuit board on which a conductive pattern is to be formed and a printing mask containing the image of the conductive pattern. The locator pin comprises a base member, an upright body member having a plurality of annularly arranged slots therein, and a threaded expansion pin fitting into the body member. The body member has a first cross-sectional area when the expansion pin is not screwed into it and a second cross-sectional area when the expansion pin is forcibly screwed into it. The first cross-sectional area of the body member is less than that of registration holes in the circuit board and printing mask, permitting the circuit board to be easily positioned adjacent the printing mask. The second cross-sectional area is at least as great as that of the registration holes so that the circuit board and printing mask are interlocked in accurate registration with one another.
