Assembly method for a printed circuit board set with centering control

Abstract

The present invention relates to a method for assembling at least two printed circuit boards (14, 16) that are electrically interconnected in the axial direction (A1) of the connection, the method comprising the step of attaching at least one centering component (36) to at least one connecting pin (26). The centering component (36) cooperates with at least one centering pin (40) held by a support element to guide the printed circuit board (16) relative to the other printed circuit board (14) in the radial plane.

Claims

1. A method for assembling at least two printed circuit boards (14, 16) that are electrically interconnected in the axial direction (A1) of the connection, a) A step of attaching at least one male interconnection element (20) to the first interconnection surface (24) of the first printed circuit board (14), wherein the male interconnection element (20) includes at least one connecting pin (26) extending parallel to the axial direction (A1) of the connection, b) A step of attaching at least one female interconnection element (22) to the second interconnection surface (30) of the second printed circuit board (16), wherein the female interconnection element (22) comprises a housing (28) that receives the connecting pins (26) of the male interconnection element (20) by insertion, c) A step of holding the first printed circuit board (14) with the first support element (76) and holding the second printed circuit board (16) with the second support element (78) so that the second printed circuit board (16) is positioned facing the first printed circuit board (14) in the axial direction, and so that the male interconnection element (20) is aligned with the corresponding female interconnection element (22) in the axial direction, d) The process includes bringing the two printed circuit boards (14, 16) close together and electrically connecting them until each connecting pin (26) is received within the housing (28) of the corresponding female interconnection element (22), thereby establishing an electrical interconnection. Prior to step d), step A) further includes the step of assembling at least one centering component (36) to at least one connecting pin (26), In step d), the centering component (36) cooperates with at least one centering pin (40) held by the second support element (78) to guide the second printed circuit board (16) relative to the first printed circuit board (14) in the radial plane. The method is characterized in that, after step d), step e) is performed to verify the connection state between the male interconnection element (20) and the female interconnection element (22) by checking the relative axial position of the centering pin (40) with respect to the second support element (78), and the centering pin (40) is movably mounted in the axial direction with respect to the second support element (78).

2. The method according to claim 1, characterized in that the centering pin (40) is provided with a plurality of axial markers (R0, R1, R2) in the longitudinal direction thereof, and in step e), the axial position of the centering pin (40) is determined by visual detection.

3.
