Title:InfluenceofProntheStrengthofAg30CuZnSnJointandFractureAnalysis
Abstract:
Thestrengthandreliabilityofjointmaterialsarecrucialinvariousindustriesthatinvolvestructuralcomponents.ThispaperaimstoinvestigatetheinfluenceofPronthestrengthofAg30CuZnSnjointandanalyzethefracturebehaviorunderdifferentconditions.TheexperimentinvolvesconductingtensiletestsonAg30CuZnSnjointswithvaryingPrconcentrations.ThetensilestrengthandfractureanalysisarethenperformedtoevaluatetheeffectivenessofPrasanalloyingelementinenhancingthejoint'smechanicalproperties.ThefindingsrevealthepotentialofPrinimprovingthestrengthandfractureresistanceofAg30CuZnSnjoints.
Introduction:
Ag30CuZnSn,acommonlyusedsoldermaterial,possessesabalancedcombinationofmechanicalandelectricalproperties.However,thejointstrengthofAg30CuZnSnisoftenaconcernduetoitsbrittlefracturebehavior.Toovercomethislimitation,alloyingelementssuchasPrareaddedtoenhancethestrengthandductilityofthejoint.UnderstandingtheeffectofPronthestrengthofAg30CuZnSnjointanditsfracturebehaviorisessentialforoptimizingjointdesignandimprovingreliability.
ExperimentalMethod:
1.MaterialPreparation:Ag30CuZnSnsolderalloywithvaryingconcentrationsofPr(0%,0.5%,1%,2%).
2.JointPreparation:Thesolderalloyisappliedasathinlayerbetweentwosubstratesandsubsequentlyreflowedtoformthejoint.
3.TensileTesting:Thepreparedjointsaresubjectedtotensiletestingusingauniversaltestingmachine.Thetensileforceandelongationatfracturearerecordedforfurtheranalysis.
4.FractureAnalysis:Thefracturedspecimensareexaminedusingopticalmicroscopyandscanningelectronmicroscopytoanalyzethefracturemorphologyandmechanisms.
ResultsandDiscussion:
