Support pin for supporting a substrate in a placement area of a placement machine

A support pin for supporting a substrate in a placement area of a placement machine, comprising an upper segment designed to support the substrate and to releasably receive the support pin via a placement head of the placement machine;

• a lower segment having at least one permanent magnet for magnetically coupling with a placement board in the placement area;
• and a central segment extending between the upper segment and the lower segment, wherein the at least one permanent magnet can be rotated with respect to a base of the lower segment by means of a rotating spindle of the support pin, wherein the base has at least one coupling area and at least one non-coupling area, such that the at least one permanent magnet is movable by means of rotation relative to the base between a coupling position, in which the at least one permanent magnet faces the at least one coupling area, and a non-coupling position, in which the at least one permanent magnet faces the at least one non-coupling area, and wherein the at least one permanent magnet is magnetically couplable to the placement board in the coupling position and is not magnetically couplable with the placement board in the non-coupling position when the support pin is provided on the placement board.
