Abstract
A method of placing a component having leads and an alignment indicating fiducial marker is provided. The method includes detecting the alignment of the fiducial marker on the component, comparing the detected fiducial alignment with a predetermined fiducial alignment and placing the component to a substrate when the detected fiducial alignment corresponds to the predetermined fiducial/alignment.
Claims8
A method of placing a component, the method comprising:
- placing a component into a nest, said component having leads and an alignment-indicating physically asymmetric fiducial marker, said physically asymmetric fiducial marker defining a portion of a bottom surface of said component that is asymmetric with respect to a top surface of said component, said nest having an asymmetrically shaped recess corresponding to the physically asymmetric fiducial marker on the component;
- detecting whether the physically asymmetric fiducial marker on the component mates with the asymmetrically shaped recess;
- and
- placing the component on the substrate when mating of the physically asymmetric fiducial marker with the asymmetrically shaped recess is detected.

A method of placing a component, the method comprising:
- forming a recess in a nest for mating with an alignment-indicating physical shape of a fiducial marker;
- placing a component in the recess, said component having leads and the fiducial marker, said fiducial marker defining a portion of a bottom surface of said component that is asymmetric with respect to a top surface of said component, the fiducial marker of said component comprising the alignment-indicating physical shape for indicating alignment of said leads upon mating with the recess;
- detecting whether the alignment-indicating physical shape of the fiducial marker mates with the recess;
- and
- placing the component on the substrate when mating of the alignment-indicating physical shape of the fiducial marker with the recess is detected.
