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. Preferably, the first marker and the second marker are of different colours, and are preferably UV compatible layers. Additionally, the method of the invention, when applied between the leads of a multi-legged component or between discrete components, such as by the etching of additional portions of the solder mask or by adding an additional layer, will produce a shadow on the reflective surface, thereby identifying a short at that location.
A printed circuit board having a plurality of areas, each of said areas being adapted to receive a component, each of said areas being marked with a marker, wherein said marker is a portion of a UV compatible layer in said printed circuit board that is exposed by etching, whereby, in use, when said components are installed in said areas, said components cover said markings so that the absence of a component in an area can be visually detected, the presence of a marker indicating that a component is missing.
A printed circuit board having a plurality of areas, each area being adapted to receive a component, at least one of the components requiring installation in a predetermined position indicative of the polarity of the component, the at least one area for receiving the at least one component requiring installation in the predetermined position being marked with a marker adjacent the area and indicative of the polarity of the component, whereby the at least one component requiring installation in a predetermined position is marked with a marker, so that when said components are installed on said printed circuit board, correct polarity of each component requiring installation in said predetermined position can be determined by inspecting the printed circuit board to determine that the marker adjacent the at least one area and the marker on the corresponding component are in alignment.
