The method consists of before commencing the insertion cycle, the data relating to the dimensions of the contact pins in relation to the connector housing, the geometry of the compliant attachment zone, the desired insertion depth as well as the diameter of the holes in the circuit board is stipulated in the control means; the insertion movement of the press starts with the insertion of the first (non-compliant) section of the pin, which should not induce any resistance force, but merely provides guidance for the pin; during said insertion movement, the insertion force and insertion depth are continually controlled; at the moment of perception when the insertion force begins to increase significantly, i.e. when the first contact is made between the underneath of one of the compliant attachment zones (FCP) of the contact pins and the upper edge of the corresponding hole in the printed circuit board, a distance remaining to be inserted (X) is defined and stored in the control means; the insertion movement is continued, taking into account the distance remaining to be inserted (X), in order to insert the contact pin to the correct depth in the printed circuit board, so that the connector housing just comes into contact with the circuit board or is positioned a small distance away from the circuit board. <IMAGE> |
