Abstract:
A method for manufacturing a programmed ECU for use in an anti-lock braking (ABS) system in a manufacturing area, the method comprising the steps of:providing a memory programmer having a programming head in the manufacturing area;programming the memory programmer with an ABS control program for the ABS system and at least one test program;conveying a semiconductor having non-volatile memory space to the programming head, the programming head receiving and retaining the semiconductor;utilizing the memory programmer to program at least a portion of the non-volatile memory space with the ABS control program;utilizing the memory programmer to test the programmed semiconductor with the at least one test program;providing a marker in the manufacturing area;programming the marker with a marking program;conveying the programmed semiconductor to the marker;receiving and retaining the programmed semiconductor on the marker;utilizing the marker to mark a surface of the semiconductor with indicia related to the ABS system based on the marking program;providing a semiconductor mounting system in the manufacturing area;conveying the marked semiconductor to the mounting system; andutilizing the mounting system to automatically mount the marked semiconductor at a predetermined position on a circuit board to obtain the programmed ECU.
