Abstract
A method of picking a component having an alignment indicating fiducial marker according to a predetermined alignment is provided. The method includes detecting the alignment of the fiducial marker of the component, comparing the detected fiducial alignment with a predetermined fiducial alignment, determining an alignment offset and picking the component in a manner that corrects the alignment offset when the offset has a predetermined value.
Claims14
A method of picking a component having leads and a predetermined lead alignment, comprising:
- forming a fiducial shape on the component, the fiducial shape being indicative of an alignment of the component;
- detecting the alignment of the fiducial shape on the component, wherein said detecting comprises:
- forming a recess in a surface of a nest, the recess sized to correspond to the fiducial shape of the component;
- and
- placing the component in the recess;
- comparing the detected fiducial alignment with a predetermined fiducial alignment to determine an alignment offset from the predetermined lead alignment;
- and
- picking the component without altering its orientation when the alignment offset has a predetermined value.

A method of picking a component having leads and a fiducial marker indicative of a predetermined lead alignment, the method comprising:
- detecting the alignment of the fiducial marker of the component;
- comparing the detected fiducial alignment with a predetermined fiducial alignment to determine an alignment offset from the predetermined lead alignment;
- providing an alignment signal corresponding to the alignment offset, wherein the alignment signal corresponds to whether the component is properly aligned in a recess of a nest;
- and
- picking the component without altering its orientation when the alignment offset has a predetermined value.
