1 Product Overview and Features
1.1 Product Overview
ThisproductisBenchtophigh-speedAutomatedOpticalInspectionsystemthatacquiredetailimageofa
PCBinonepassbyusingalinescansensorcameraandstoreallinformationembeddedintheimagesin
acomputer memory to conduct high speed inspection and judgement by employing Saki original image
processingtechnology.
BF-SiriuscanbeusedinanystageofPCBmanufacturingprocessfrommanualmountingtoautomated
post-print,post-mount,aswellaspost-ow/reowinspections.
1.2 Features
1.2.1 System Structure
ThisiscompactandeasytouseBenchtopHighSpeedAutomatedOpticalInspectionsystem.•
ThemachineequippedwithnewlydevelopedCCDcameraandilluminationlightingtorealizehigh
throughputforscanofLsizeboard(460(W)×500(L)mm)withinapproximately10seconds.
TheclearanceofPCBfrom40mmfortopsideand60mmforbottomsideisnewlydesignedto•
enablehandlingPCBsmountedwithverytallcomponents.EvenifthePCBwarpageisapproximately
2mm,topsideclearancestillallows38mmcomponentheightfromPCBsurface.
1.2.2 Lighting and Image Acquisition
SwitchingbetweenthreedifferentLEDlighting,• TopLight (Coaxial Overhead illumination), Side
Light, and LowLight,enableacquiringthreekindsoftheimagesonlyinonepass.
Byusinglinesensorcamera,thesystemachievehighdenitionimagesof• 18μm.
Shadingtechnologycompensatesimagebrightnessautomaticallysothatitwillalwaysbeunder•
thesameconditions.
Thetelecentriclensopticsincreasesinspectionaccuracy.Bythisaccuracyimprovement,virtually•
distortionfreeimagescanroutinelybeacquired.
1.2.3 Expanding Whole Board Image on Memory
Withlinescantechnology,imagedataofentireboardcanbestoredinthememory,ratherthan•
partial area images, and therefore all essential operations including inspection data creation,
judgementwithalgorithmicroutines,canbeimplementedatveryhighspeed,effectivelyshortening
tacttime.
Imagedataoncestoredinmemoryarekeptuntilthenextimageisscanned,sothereisnoneed•
torescantheimageeverytimeforedition,orinspectionpurposes.
1.2.4 Inspection Data Management with Inspection Library
ImagecanbeacquiredwithexactsameilluminationconditionsanywhereonthePCB.Oncethe•
componentdataisregisteredasalibrarydata,itcanberetrievedagainforsimilarcomponents,
thussimplifyinginspectiondatacreation.Incasethesamecomponentsaremountedondifferent
PCBconditionsarenotidentical,thelibrarydataofthecomponentmaynolongerbeapplicable,
thusmightrequiretoappenditasnewentryintothelibrary.
