Any insertion or any X Y location on the board can be selected to define a board error correction hole location. In the example, holes are selected on Circuit 1, Circuit 2, and Circuit 4. Note that the hole selected on Circuit 1 is not copied to its associated offsets. . Only insertions or X Y locations on the selected circuit can be selected to define a circuit error correction hole location. In the example, the three holes selected on Circuit 1 are copied to each associated offset. . Offset Selected: Any number of BEC holes can be defined on the selected offset. Hole locations are not copied to other circuits or offsets. . Table Rotations: #NAME? -Only insertions for the last selected table rotation are available. Insertion holes for previous rotations are filled by the component leads as those rotations are processed by the machine. For example, on an axial machine, if the 90° checkbox is selecte To define correction locations: 1. From the Steps window, select: Special Steps > Add > Board/Circuit Error Correction The Select Board/Circuit Error Correction Circuit dialog box is displayed. 2 . If Board is selected, the Board Error Correction dialog box is displayed. . If Circuit 1 is selected, the Circuit Error Correction: Circuit 1 dialog box is displayed. 3. In either case, there are two ways to select board/circuit error locations. . To use insertion locations, select the insertion from the Ref ID (Component ID) list box and select the Add button. The selected insertion is copied to the Error Correction list box. . To define correction locations not related to a specific insertion, enter the coordinates in the X Position and Y Position entry fields and select the Add button. The coordinates are copied to the Error Correction list box. Up to three locations can be defined for a BEC step. Selecting the Add button defines a BEC location. Selecting OK defines a BEC step. Any number of BEC steps can be defined per circuit per rotation. If defining Circuit Error Correction locations, to have the locations defined on all associated offsets of the circuit, select the Define for Offset Circuits checkbox (checkmark visible). If the checkbox is cleared, the locations are only defined for the selected circuit. If defining Board Error Correction locations, this checkbox is disabled. To define correction locations on rotations other than table rotation 0°, select the desired rotations from the Perform Correction at Table Rotation(s) group box. Only rotations that have insertions are enabled. . If correction locations are defined that cannot be reached at one or more table rotations, an error message similar to the following is displayed. . If an insertion location from the 0° table rotation is selected as a correction for the 90° table rotation, an error message similar to the following is displayed. This means that the hole selected for the correction at the 90° table rotation is already populated with the component so the correction cannot be performed. Select OK. 4 . Two insertions selected for a board. . Two locations selected for a board. . Two Insertions selected for a circuit. . Two locations selected for a circuit. 5 Change Correction Locations To change an existing correction location: 1 Use the right trackball (mouse) button to select the Circuit or Board Error Correction step to be edited. A pop-up menu is displayed. 2 Select Edit from the pop-up menu. The Board (or Circuit) Error Correction dialog box is displayed. The current correction locations are displayed in the Error Correction list box. In the example, step 1 uses ................ in circuits 1, 3, and 4 3 From the Error Correction list box, select the location(s) to be edited. 4 Select Remove to delete the location from the list box. 5 Select another insertion or enter position coordinates and select Add. 6 Select OK. The new information is now displayed in the selected Board (or Circuit) Error Correction step. In the example, step one now uses ................ in circuits 1, 4, and 2. Auto Miss Mark (dual head machines only) Use the Auto Miss Mark (AMM) option to define a location on a board or circuit for a stamp mark that indicates that a misinsertion has occurred. The stamp is visible to an inspector indicating that the board is not complete. Considerations:
