Abstract
A method for manufacturing a sensor for motor vehicles, includes placing a camera facing the leadframe to generate a sequence of images showing at least one positioning reference system and at least one measurement cell or an integrated circuit, detecting the at least one measurement cell or integrated circuit in images generated by the camera, determining the position of the at least one measurement cell or integrated circuit relative to the at least one reference system, applying a first marking to the baseplate, the first marking containing information representing the determined position, overmolding the assembly formed by the support zone and integrated circuit, with the at least one reference system still being visible, positioning the magnetic element in the electromagnetic proximity of the at least one measurement cell, detecting the magnetic element in the images generated by the camera, determining the position of the magnetic element relative to the at least one reference system, and applying a second marking to the sensor, the second marking containing information representing said determined position.
