Abstract
A method of verifying a predetermined lead alignment of a component having a physical asymmetry corresponding to an alignment of the leads is provided. The method includes placing the component in a recess in a surface of a nest, wherein the recess corresponds to and mates with the physical asymmetry on the component and detecting whether the physical asymmetry has mated with the recess.
Claims35
A method of verifying a predetermined lead alignment of a component having leads, the method comprising:
- forming a fiducial physical asymmetry on the component indicative of the predetermined lead alignment on the component;
- forming a recess in a nest, such that the recess corresponds to and mates with the fiducial physical asymmetry on the component;
- placing the component in the nest;
- and
- detecting whether the fiducial physical asymmetry has mated with the recess to verify the predetermined lead alignment.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- and
- detecting whether the fiducial physical asymmetry has mated with the recess.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- detecting whether the fiducial physical asymmetry has mated with the recess;
- and
- picking the component from the nest.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- detecting whether the fiducial physical asymmetry has mated with the recess;
- and
- providing an alignment signal.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- detecting whether the fiducial physical asymmetry has mated with the recess;
- and
- placing the component to a substrate when the component mates with the recess.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- directing a pattern of radiation across the nest;
- and
- detecting at least a portion of the radiation pattern to determine whether the fiducial physical asymmetry has mated with the recess.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- and
- utilizing a detector disposed in the recess to detect whether the fiducial physical asymmetry has mated with the recess.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- detecting alignment of the component in the recess;
- and
- comparing the detected component alignment with a predetermined fiducial alignment.
A method of verifying a predetermined lead alignment of a component having leads and a fiducial physical asymmetry indicative of the predetermined lead alignment, the method comprising:
- placing the component in a recess formed in a surface of a nest, wherein the recess is shaped to mate with the fiducial physical asymmetry of the component;
- detecting whether the fiducial physical asymmetry has mated with the recess;
- and
- causing a pick and place machine to pick a misaligned component.
A method of verifying a predetermined lead alignment of a component having leads, the method comprising:
- placing a component having a fiducial physical asymmetry indicative of the predetermined lead alignment into a nest having a recess that corresponds to the fiducial physical asymmetry;
- directing a pattern of radiation across the nest above the recess;
- receiving the radiation after the radiation passes over the nest;
- and
- comparing the received radiation pattern to a predetermined radiation pattern.
