Thickness Of Cu Ni 6sn5 Imc After Reflow Download Scientific Diagram Download scientific diagram | thickness of (cu, ni)6sn5 imc after reflow from publication: highly thermostable joint of a cu ni–p plating sn–0.7cu solder added with cu balls | solder joint. Download scientific diagram | thickness of the (cu,ni)6sn5 imc at the ni–p and ni plating interface after reflow from publication: highly thermostable joint of cu ni plating composite sn–0.7cu.

Thickness Of The Cu Ni 6sn5 Imc At The Niвђ P And Ni Plati Download scientific diagram | the imc growth process after assembly reflow for 100 ␮ m pitch from publication: the size effect on intermetallic microstructure evolution of critical solder. Interfacial imc growth during isothermal aging. for the as soldered state, a continuous cu 6 sn 5 imc layer with an average thickness of 0.32 μm was observed at each interface of the cu sn cu. Thus, only the imc thickness at the (001)cu cold end and ni hot end was shown in fig. 5. the interfacial imc growth can be usually defined by the equation: (1) h = kt n. download : download high res image (516kb) download : download full size image; fig. 5. relationship between interfacial imc thickness and reflow time: (a) h t and (b) lnh lnt. The reaction between the molten solder and electroless ni layer resulted in formation of a ternary (cu, ni) 6 sn 5 imc at the interface. this interfacial imc layer was continuous, and with a faceted morphology. the thickness of the imc layer as a function of both reflow time and temperature was also investigated.

Cu is a common surface finish for soldering substrates in electrical applications. research has shown that the imc between sn based solder and cu consists of cu 6 sn 5, formed after reflow, and cu 3 sn, formed after isothermal aging [11–13]. the amount of kirkendall voids is proportional to the growth of the cu 3 sn layer [14–16]. A single fine dendritic (cu, ni)6sn5 imc at the interface of microalloyed joint was observed and evolved into a larger scallop or layer like duplex imcs ((cu, ni)6sn5 cu3sn) after the aging. considering the combined effect of cu, ni, and ag, the microalloyed joints exhibited the improved microstructure relative to ordinary counterparts and.
