SMT产品线撞件不良分析与改进措施
Title:AnalysisandImprovementMeasuresforSMTProductLineCollisions
Introduction:
SurfaceMountTechnology(SMT)hasbecometheleadingmanufacturingprocessintheelectronicsindustryduetoitshighefficiencyandcost-effectiveness.However,likeanyothermanufacturingprocess,theSMTproductlineispronetovariousqualityissues.Onesignificantproblemiscollisionsbetweencomponentsduringtheassemblyprocess,whichcanleadtodefectsandultimatelyaffecttheoverallproductquality.ThispaperaimstoanalyzethecausesofcomponentcollisionsintheSMTproductlineandproposeeffectiveimprovementmeasurestominimizetheseincidents.
