5 SP50 Overview SP50 Description The SP50 machine measure solder paste deposits before components have been placed on the boards. LED Ring Inspection A ring of LEDs is used to inspect fiducials. 3D Paste Inspection The SP50 uses 100% 3D paste measurement to find errors that lead to pasterelated problems, as shown in the following table. Problem Type Bridges/open joints Paste profile Missing/insufficient paste Stencil misalignment Smears Measurement Type Volume Height Area, Volume XY Offset Area C 5

6 Operator Tasks - Summary Tasks An SP50 operator performs several important tasks. These are summarized in the following table and described in detail in subsequent chapters. Step Action 1 Select a new board program When a new board type is to be inspected, select the board program. The board program specifies the positions and sizes of the paste deposits. 2 Review all errors on the board and pass or fail the board. If the SP50 detects failing deposits, view each failure on the monitor to verify whether the failures are real. Based on this review, pass or fail the board. The system then ejects the board. Note: When you enter into Action On Failure mode you can eject the board at any time to examine it. 3 Notify an engineer if the SP50 cannot inspect a board. If you encounter problems inspecting a board, or if the fiducial inspection fails to be carried out successfully, notify an engineer C 6

20 SP50 Main Interface Main Parts The Operator interface is the primary interface where the operator can view the board layout, select programs, review defects, and view inspection summary information. Some of the items will be explained in more detail throughout the manual. The following items are on the main Operator interface: 1. Toolbar 2. Board Display 3. Deposit Results/Thresholds 4. Action on Failure Menu 5. Machine Status 6. Error Summary 7. Inspection Summary 8. Run Summary C 20

21 Toolbar The toolbar in the main interface contains only a Board Select button and a View Board button when the SP50 interface first opens. Use the Board Select button to select a board program. As soon as you load a program, the SP50 system automatically inspects the board once a board is loaded. Also, the Results button becomes active once a board has been inspected and contains defects. Board Display The Board Display shows the location of all deposits on the board. When you inspect the board, passing deposits turn green and failing deposits turn red. Note: The blue lines show the path of the camera as it moves over the board C 21

22 Machine Status The Machine Status toolbar displays the status messages for the conveyor and the progress of the inspection. The first field provides information about the SP50 readiness for inspection or receiving a board. The second field displays what signal is being given to the downstream conveyor. Examples would be Waiting for Board, Downstream Busy Rail 1, Machine in Use, and so on. Finally, the lower field shows the progress of the board inspection C 22

26 Inspecting a Board Steps Inspect a board using the following steps: Step Action 1 Confirm that the correct inspection program is loaded by verifying the program name in the upper left portion of the main operator interface. 2 Load a board into the machine. 3 The SP50 system automatically starts inspecting the board. Deposits that pass inspection turn green and failing deposits turn red. When inspection is complete the machine enters AOF mode. For more information, see Chapter C 26

27 Fiducial Inspection Fiducial Inspection Fiducials are features on the board that the SP50 uses to align SP50 coordinate system to the coordinates of the board. The SP50 automatically carries out 2D inspection to determine the location of the fiducials. Fiducial Description Fiducials are usually circular, and the can also be shaped like diamonds, rectangles, crosses or bowties. The engineer who wrote the board program will already have programmed the fiducials shape and location into the system. If the fiducials are not set up correctly, the following message will appear: There are four options: The Retry button is used to attempt fiducial inspection again. Manual Find lets you attempt to manually navigate to the fiducial. Scale makes changes to the system, and is generally not recommended. Dismiss ends the attempted finding of the fiducial. In general, you click the Retry once or twice, and if it still fails, click Dismiss and call your engineer C 27

28 Chapter 4 SP50 Defect Review Cycle Introduction This section describes the SP50 Defect Review process and associated functionality. Contents This chapter is has three sections: Section See Page Action on Failure Options 29 Pass or Fail Board Options 40 Inspection Summary Information C 28

29 Action On Failure Options AOF Toolbar If the SP50 system detects failing deposits, it enters Action on Failure (AOF) mode when the inspection finishes and displays information about the first failed deposit. The buttons used during the Action on Failure process are described below. Steps View errors using the following options: C 29

30 Step Action 1 The deposit inspection information is summarized in the Deposit Results/Thresholds screen on the interface. The Error Count shows the current and total number of defects. Deposit displays the reference designator and pin number. Shape is either the aperture information from gerber or the associated component type for the deposit. Device type is the algorithm which is used on the device and includes the paste size and fill factor. The lower portion of the screen shows both the Measured values and the Thresholds for each variable measured on the SP50. This provides the operator information about the severity of the defect. This menu also shows if the deposit fails for bridging C 30

31 Step Action 2 The operator can navigate between defects by selecting the Next and Previous buttons from the interface. Note: Click the Previous button if you want to view the errors you have previously viewed. If you are looking at the first error the Previous button is disabled C 31

32 Step Action 4 The 3D Image is the default image which is displayed upon navigation to and from the different defects. This image also includes two different board graphics to display the deposit location on the board: The 3D image is a grayscale image where the brightness of the different pixels is relative to the height of the deposit at the point. For instance, the defect shown above displays a light grey color for the small deposit and dark grey for the pad and board C 32

33 Step Action 5 The 2D View button shows 2D camera view of the current deposit and the surrounding board area C 33

34 Step Action 6 The SSM (Solid Shape Modeling) button displays a rendered 3D image of the deposit which allows the user to rotate and analyze the deposit from different perspectives. When finished viewing the SSM image, the user can close the window by selecting the X in the upper right corner of the screen C 34

35 Step Action 7 The Results button displays the inspection results. Red boxes indicate failing deposits and green boxes indicate passing deposits. Summarized stencil x-y offset and skew values are also displayed in the upper portion of the results screen. These values can be used for optimizing the alignment of the stencil on the printer C 35

36 Step Action 8 The Deposit button in Historical Information displays a chart of the average performance of deposits similar to the active defect along with the results of that particular deposit over the last several inspections. This enables the user to compare the differences between the current deposit results and others which are similar for better error review C 36

37 Step Action 9 The Type button in Historical Information displays only the chart of the average performance of deposits similar to the active defect. This enables the user to gain a general understanding of the performance of that particular deposit type C 37

38 Step Action 10 The Offset button in Historical Information displays a chart of the average stencil offset and skew for the last several views. This information is useful for optimizing the printer parameters related to stencil alignment C 38

39 Step Action 11 Click the False Fail button to mark a deposit as a false fail. A box will appear and the reason why you are marking the deposit as a false fail should be entered into the box as shown: C 39

40 Passing/Failing a Board Description After examining all failing deposits on a board, you can pass, fail or eject the board. If you believe all of the failing deposits are not real failures (false fails), then Pass the board. Note that functionality can be enabled to prevent the operator from passing the board unless all deposits are marked false fail. Until this occurs, the Pass button will remain grayed out. If you believe there are real failing deposits, then Fail the board. If you want to halt inspection or look at the board more closely, then Eject the board. If this function is used, then the board must be Passed or Failed after reviewing in order to complete the inspection cycle C 40

41 Inspection Summary Information Description After you have passed or failed the board, the software updates the result statistics in the toolbar. The Error Summary displays the number of defects which occur on the last board inspected. It categorizes the defects to allow the user to get a general understanding of the printing issues C 41

42 The Inspection Summary displays the general information about the last inspection regarding total number of defects and deposits inspected. Also, the total cycle time (including load/unload and error review) and machine inspection time. Finally, the bare board vendor and barcode information about the last board inspected is displayed at the bottom. The Run Summary displays the total number of boards inspected in a production run with the percentage passed and the number of boards with failures. The user has the ability to Reset the information for a new production run by selecting the Reset button. Also, the last reset information is displayed for reference C 42
