For example, when the positioning mechanism for the integrated circuit board is used, the integrated circuit board is vertically arranged and attached to a hollowed-out positioning plate, a user rotates the operating wheel with a hand to enable the operating wheel to drive the cam to rotate, the cam pushes the positioning column to move longitudinally, so that the positioning column moves towards the positioning plate, the flexible pad is further abutted on the integrated circuit board to complete positioning of the integrated circuit board, and then a welding tool or a gluing tool can be used for performing subsequent processing on the integrated circuit board on the other side of the hollowed-out positioning plate. Because the end part of the positioning column is provided with the flexible pad and the flexible pad is used for abutting and positioning the integrated circuit board, the integrated circuit board is not easily damaged by the positioning column by utilizing the flexibility of the flexible pad.
For example, in order to facilitate driving the positioning posts to reciprocate longitudinally to position the ic board or release the ic board, the base plate is a rectangular plate, and the width of the extension plate is smaller than that of the base plate. The positioning frame and the ferrule are respectively arranged on two opposite sides of the substrate.

For example, in order to prevent the positioning column from loosening, the thickness of the cam is 5 times of the diameter of the positioning column, so that the positioning column still abuts against the peripheral surface of the cam without loosening even if the cam moves longitudinally by a certain amount during the rotation of the cam. And the thickness of the ferrule is larger than that of the operating wheel, so that the operating wheel is not easy to loosen from the ferrule even if the operating wheel moves longitudinally to a certain extent relative to the ferrule. And because the operating wheel only makes 180 degrees of forward and reverse rotation, namely reciprocating rotation, the longitudinal displacement of the cam is not too large.
