Abstract
An electronics part verification system may comprise a test-site board loaded onto or otherwise secured to a PnP machine and computer instructions for using the PnP machine's capabilities to (i) retrieve a component-to-be-verified from a feeder; (2) move the component to a test site on the test-site board; (3) use an LCR meter to obtain an inductance, capacitance, or resistance value for the component; and (4) determine, based on the value from the LCR meter, whether the component is correct or incorrect.
Claims20
An apparatus, comprising:
- a pick-and-place (“PnP”) machine;
- a printed circuit board (“test-site board”) comprising a test site and an onboard LCR meter or multimeter connected to the test site, wherein the test-site board is dimensioned to be loaded onto the PnP machine and has been loaded onto the PnP machine;
- computer-readable instructions stored on a non-transitory computer-readable storage medium (“PnP Instructions”) that, when executed, cause the PnP machine to:
- retrieve a two-terminal component-to-be-verified (“component”);
- and
- move the component to the test site;
- and
- non-transitory computer-readable instructions (“Analysis Instructions”) that when executed cause an analysis module to:
- retrieve from the onboard LCR meter or multimeter at least one value of the component;
- determine, based on the at least one value read by the LCR meter or multimeter, at least one from the following list:
- that the at least one value read by the LCR meter or multimeter matches a specification value of a target component;
- that the at least one value read by the LCR meter or multimeter does not match a specification value of a target component;
- that the at least one value read by the LCR meter or multimeter matches a specification polarity of a target component;
- and
- that the at least one value read by the LCR meter or multimeter matches a specification polarity of a target component.

A method, comprising:
- retrieving, using a pick-and-place (“PnP”) machine, a two-terminal component-to-be-verified (“component”);
- moving, using the PnP machine, the component to a test site on a test-site board, wherein the test-site board is at least one from the following list:
- loaded onto the PnP machine using the same machinery or mechanics that the PnP is configured to use for loading a printed circuit board for assembly including placement and attachment of components;
- secured to the PnP machine;
- and
- secured to a location that is fixed relative to the PnP machine;
- using an LCR meter/multimeter to measure a value of the component;
- determining, based on the at least one value measured for the component by the LCR meter or multimeter, at least one from the following list:
- that the at least one value measured for the component by the LCR meter or multimeter matches a specification value of a target component;
- that the at least one value measured for the component by the LCR meter or multimeter does not match a specification value of a target component;
- that the at least one value measured for the component by the LCR meter or multimeter matches a specification polarity of a target component;
- and
- that the at least one value measured for the component by the LCR meter or multimeter does not match a specification polarity of a target component.
