lower limit :0） -Activate window, make copy on the cross of X / Y direction 6.2.5 Tombstone T W Capacitance sideward happens while W≠T or while W largely differs from T As the condition of W>2T or T>2W, an inspection project needs to build As for big difference, to use the calculation of ContoursFind If the real component tolerance error is set to be, the inspection project works totally 73 Chapter Six Ver 2.0 6.3 IC general database a JUTZEAOI adopts photo camera to capture the photo For straight display and convenient operation, we employ the full vision photo When the real component size is bigger than the max size a camera can capture, it needs to be decomposed of several parts for the inspection （FOV: the single photo size from the camera is effected by its definition.）; The above component size nearly exceeds the max size that the camera can capture b Main components base: setting measurement c Set up CAD window fit to body size -Active the window, right click mouse bottom -Create sub component -Set up window number and location in X/Y direction, the component in picture is QFP, so create sub-window, choice TopBottom and LeftRight option 74 Chapter Six d The yellow windows in the picture e Adjust cad window size again, not over one FOV size Double click the main window, we can edit main body Edit sub window one by one Sub lib name is the same as main component 75 Ver 2.0 Chapter Six Ver 2.0 6.3 IC inspection items InsfSolder LiftLead Missing Bridge Main comp Shift Sub comp BadFilled WrongPart Reverse Main component: Missing, Shift, WrongPart, Reverse etc Sub component: Pin InsfSolder, LiftLead, Bridge, BadFilled 76 Chapter Six Ver 2.0 6.3.1 Missing Missing part belongs to qualitative inspection project without the problem of quantization, the same as Chip component Open a new window - Choose element type （QFP） - Measure the real element and name the component base, IC （SOP/QFP/SOJ…） We usually use U for the type - This element base name: U6（version; to add depending on the practical condition） - Choose NG type （missing part） - Choose calculation （Scale） - Draw window size to be right and place it properly （as the component missing part happens, the bright and color contrast from the right place of window reach the max ） - Extract bright and color in the window - Set the judging threshold 77 Chapter Six 6.3.2 Shift Open a new window - Choose NG type （Shift） - Choose calculation （Scale） - Draw window size to be right and place it properly - Extract bright and color in the window -Set the judging threshold -X/Y direction copy if necessary 78 Ver 2.0 Chapter Six Ver 2.0 6.3.3 WrongComp Algorithm： -OCR -ImageMatch -OCVBIN Open a new window - Choose NG type （WrongComp） - Choose calculation （OCR） - Adjust window size and place it properly - Extract bright and color in the window -Set the judging threshold （This instance employs character 248T; standard character setting: 248T, for character quantity, the upper limit: 4, the lower limit：1-4 ） ImageMatch：The character is not to need to extract bright and color WrongComp another inspection way - Choose calculation （ImageMatch） - Adjust window size and place it properly - Choose window （set the selected photo as the template） - Re-draw the window to be right size (set the search scope for ImageMatch) - Set the judging threshold ImageMatch: the supreme property is that no need to set or extract bright and color value 79 Chapter Six Ver 2.0 6.4 Sub component lib Note: pin edge and pin number Main component: green window, sub component: yellow Sub component inspection items: pin InsfSolder, LiftLead, BadFilled, Bridge, 6.4.1 Sub component window Double click one yellow window, enter edit page There is default window（PadSearch）to locate pins - Choose calculation （LeadBox） - Adjust window size and place it properly - Extract bright and color in the window -Set parameters step by step（pitch, length, pin numbers etc.） 80 Chapter Six InsfSolder inspecting is just like Chip Open a new window - Choose NG type （ Insfsolder ） - Choose calculation （ Scale ） - Adjust window size and place it properly - Extract bright and color in the window Copy Insfsolder window - Choose NG type ( LiftLead ) - Choose calculation （ Scale ） - Adjust window size and place it properly - Extract bright and color in the window Do other NG inspection windows by the same way 81 Ver 2.0 Chapter Six Ver 2.0 6.5 Create View After add/delete components, or adjust window( including sub window), we will assign view of board image 82 Chapter Six Ver 2.0 6.6 Top/Bottom sides program Complete top side program first Then choice a special mark to distinguish top/bottom side, add one new component: SideMark—type（SideVerify） special mark 83 Chapter Six Ver 2.0 Edit SideMark, use correct algorithm After complete SideMark edit, choice ―A/B‖ to B, load CAD data of bottom side Do the same way with top side program, choice ―Append data‖, then the program normally 84 Chapter Six Ver 2.0 6.7 BadMark setup We can use BadMark function to skip when important defects happen in sub-board Choice a special mark, add one new window: BadMark—type （ BadMark ） Edit BadMark, use correct algorithm Save and exit Note: BadMark must be setup in every sub-board 85 Chapter Six Ver 2.0 Ver 2.0 release note The version released on Jan 2014 The version is based on CVImageEditor 2.0.3.3247-en The new version update new algorithm and function: - GetDistance - Calculations - DefectFinder The new version delete old algorithm: - ICSearch - EndSearchScale After version V3211, need new DLL files when update After version V3211, old files ― ipp*.dll‖ would move to new folder to backup, not show on the jutze folder 86 ...Ver 2.0 Preface  Thank you for your purchasing JUTZE AOI system  The manual is suitable for technical engineers who use AOI machines  The manual makes graphic description in detail on algorithm,... 2.0 1.2 JUTZE AOI brightness principle Range of brightness 255 The value of brightness:0 - darkest, 255 – brightest Input light NG OK Component Reflect light 1.3 JUTZE AOI color principle JUTZE. ..
