  • Method for the verification of the polarity, presence, alignment of components and short circuits on a printed circuits board
    Patent number: 6480394
    Abstract: The invention relates to a method for the verification of the presence and proper orientation of a component on a printed circuit board. The board has a plurality of areas for receiving a component respectively. Each area is marked in the center thereof with a first marker. Adjacent each area, and indicative of the polarity of the component, a second marker is marked on the board. The presence or absence of a component can be evaluated by inspecting the board after it has been populated and determining whether any of the first markers appear, indicating that a component is missing. Verification of the polarity of a component is done by placing a marker on a portion of a component required to be installed in a predetermined position indicative of polarity. Inspection of the board once it has been populated will determine if the component is in the proper orientation by verifying if the second marker and the marker on the component are in alignment.
