Operations | Reference Manual Forward Why First Article? Prior to manufacturing any product, all assembly data1 and materials2 should be reviewed for accuracy and completeness. Then, a First Article Inspection can be performed to validate that the physical first assembly has been constructed in accordance with the design specifications prior to releasing the line for full production. This process is simply known as the “First Article,” which is the primary function of the FA Inspector.
FA Inspector (AOI) Scanner AOI Mode Utilities The FA Inspector comes with (2) two very powerful built-in utilities and one highly recommended third-party software package: CXF Editor Layout Viewer Microsoft Excel™ CXF Editor Overview The CXF Editor provides comparison and validation of CAD (XY data) against the Bill of Materials (BOM) and generates fully validated CXF files.
Operations | Reference Manual Loading a PCB f or Inspection Loading or “staging” a PCB is a process common to all FA Inspector System modes of operation. As this will be the reference for all tests it is of the utmost importance to perform this step correctly. Inspection Drawer and Table Assemblies The FA Inspector PCB inspection area is accessed via a front panel drawer containing a Table with Alignment Grid, (5) Magnetic Posts and (1) 90° Magnetic Alignment Guide.
FA Inspector (AOI) Scanner Inspection Drawer Clearance and Standoff Shelf Calibrations PCB Handling (ESD Notes) The standoff blocks and table grid mat are made from ESD compliant materials; specifically Delrin (polyoxymethylene plastic) which is rated ESD electrostatic dissipative safe. In addition, the FA cabinet, frame and drawer assemblies are grounded via the power cable ground wires.
Operations | Reference Manual 4. Position the board at the center of the table and “stage” the PCB using the magnetic standoff posts. The board should be well supported, stable and squarely aligned with respect to the table grid. Best Practice: The FA Inspector is by factory calibrated at the 20mm stand-off height. Therefore, when possible, always position the sample at the 20mm stand-off height to obtain the best focus, lighting and scan detail. Inspection Drawer and Table Assemblies 5.
FA Inspector (AOI) Scanner PCB Staged Using 20mm Stand-Off Height Best Practice: To avoid any chance of collision, do not block the left side of the PCB by placing a post at the left edge of the circuit board. In 99% of all PCBs, if you can close the drawer without the board touching any part of the cabinet, then there is very little chance that the scan head could collide with any part of the PCB. Exception: Flip-up connectors and switches that could change state after the drawer is closed.
Operations | Reference Manual Comparator Mode Comparator Mode Overview Comparator Mode allows operators to perform fast inspection “comparisons” of two or more PCBs with minimal setup (~5 minutes) and NO programming. The Comparator uses a "Golden Board" as test reference. The operator selects two (2) alignment points to provide automatic alignment of next PCBs loaded/scanned for comparison. Inspection views are selected for best inspection accuracy (magnification) and speed (throughput).
FA Inspector (AOI) Scanner Required Items (Comparator Mode) Before setting up a new board in Comparator Mode; select a PCB assembly and validate a “Golden” board for inspection reference. See the table below for details. # Required Items Remarks 1 Two (2) populated PCBs Comparator Inspection: One (1) golden board is used for test reference and at least one (1) additional board for comparison.

FA Inspector (AOI) Scanner Comparator Mode Inspection Reports By displaying enlarged regions an operator can rapidly step-thru and evaluate detailed visual differences. If defects are found, they can be identified using “Fault Markers” that communicate part, fault classification and location. This information is used to generate reports, which may be viewed on screen, stored (local or network), printed or emailed.
Operations | Reference Manual AOI Mode AOI Mode Overview The FA Inspector AOI Mode allows inspection routines to be “taught-once and run many times. This is accomplished by scanning an image of a Printed Circuit Board Assembly (PCBA) and using (CAD/CXF) data to locate and identify devices. Each “unique” device type is defined by interactively stepping through the parts, drawing a Region of Interest (ROI) around key device features and checking basic visual test parameters (i.e.
FA Inspector (AOI) Scanner Required Items (AOI Mode) Before setting up a new board in AOI Mode; select a PCB assembly and obtain the CAD or XY (Pick-&-Place), BOM and Assembly Drawing data for this board. See the table below for details. # Required Items Remarks 1 Two (2) populated PCBs AOI inspection: One (1) bare board of the same PCB can also be useful to verify thresholds are properly set.
Operations | Reference Manual CXF File Development CXF (Cad eXchange File) is a native file type used by the FA Inspector to automate AOI Mode operations during First Article Inspections and ongoing quality inspection tasks. The FA Inspector has a built-in CXF Editor tool that provides comparison and validation of CAD6 and BOM7 files. This is accomplished to confirm that both files contain the same key device data; and to insure that the assembly is built in accordance with the BOM.
FA Inspector (AOI) Scanner CXF Editor Operation Acquire the CAD and BOM files used to manufacture the PCB. Import the CAD and BOM files, run , review and resolve discrepancies or auto-label as DNP (if any and as applicable).

Devices Identified as “Do Not Place” (DNP) 4. Review of the CXF file to confirm that all elements are laid out correctly.
FA Inspector (AOI) Scanner Sorting CXF Device Data Best Practice: Sorting the Part Number and Reference Identification columns will provide improved inspection logic during the inspection routine development or First Article Inspection. 1. Open the CXF file in Excel™; highlight the entire area containing device information including the header row. The contents between DATA_Start and DATA_END. Sorting Device Data Using Excel™ 2. Select from the Excel™ Top Menu Bar.
Operations | Reference Manual 3. CONCLUSION: The resulting file will be sorted first by Part Number then by Reference Designator. Because CXF files are read by the FA Inspector in this manner the inspection process will follow and ordered path according to Part Number and Reference Designator groups.
FA Inspector (AOI) Scanner Creating CXF Files with MS Excel™ XY data can easily be converted to CXF (Cad eXchange File) format using any non-formatting Text Editor (i.e., notepad). However, it is recommended that you use Excel™ which is very well-suited for this task. The following procedures use Excel™ for this operation. Best Practice: To avoid missing any of the required CXF data and format, it is a good practice to begin each XY-to-CXF conversion task by using a “CXF formatted template.

Operations | Reference Manual Fine Tuning AOI Mode Inspection Routines Once the initial test routine has been developed it’s always a good practice to fine-tune and validate the inspection setup for proper setup and operation prior to releasing the test for use. A useful method to fine-tune an inspection routine is to run (3 or more) assembled boards of the same board type.
FA Inspector (AOI) Scanner Editing / Deleting Templates AOI Mode uses template-matching instead of algorithm-based analysis; which dramatically speeds up test development and does not require programming. However, the precision of the inspection results relies heavily on the quality of the templates selected. Therefore, the idea is to select a device inspection area with distinctive and consistent markings.
Operations | Reference Manual Adjusting Threshold Settings By default each new device trained is given an ideal score of 700. Components that pass test at the 700 setting are exceptional clear, well-labeled, devices with good contrast and excellent solder characteristics; most devices do not fit this criterion and therefore must be adjusted or fine-tuned.
FA Inspector (AOI) Scanner Validating Inspection Routines One method of test routine validation is to inspect a bare board. Inspecting a bare board verifies that inspection threshold settings are not configured too low — a proper indication would be that all parts should fail during this test. If they do not, then either a threshold is set below the recommended level for that device type. To correct this type of test error, see: Fine Tuning AOI Mode Inspection Routines. 1.

Result of parts lost during pick-and-place operations or Disturbed Joint causing the part to fall off during transport.
FA Inspector (AOI) Scanner Short or Bridge The primary causes of shorts are defects in the attachment, and typically are bent pins, a significantly misaligned component, or excess solder that is resulting in an electrical short between two electrical nets. Blow Holes A bubble or open area caused by trapped gas inside a solder joint while cooling, aka “out gassing.” If the some of the gas escapes during the solder process this can cause “pin” holes, bubbles or “blow holes.
Operations | Reference Manual Appendix C – AOI Template Training Guidelines Template Training Methods and Settings AOI Mode uses a template-matching technique (object linking and embedding; known as OLE or MS™ ActiveX) to perform automated optical inspections. The precision of the inspection results relies heavily on the quality of the templates selected. Therefore, the idea is to select a device inspection area with distinctive and consistent markings.

If it is a long label you may need to break up the template into two or more “Templates”.
Operations | Reference Manual Template Selection Strategy By grabbing too much of the background in combination with a low threshold setting (~550); small dark bodied discreet components (in combination with a dark FR4 material background); may cause false calls, as there is not be enough difference in coloration (digital information) to catch presence/absence. Using a bare board is VERY IMPORTANT when thresholds are set below 600 to fine-tune and eliminate false-calls or escapes.
FA Inspector (AOI) Scanner Understanding Device Positions It is important to have a good working knowledge of device positions used by the AOI Mode software. Centroid Position By definition, the centre of the Device Outline is the Device’s centroid position. A small purple colored cross or dot marks the centroid position. This is the center XY reference position of a Device. All other device-related operations are relative to this centroid position.
