Eds Analysis Of Imcs Between Solder And Niвђ P Cu A Eds Pattern Download scientific diagram | eds analysis results of: (a) (cu, ni)6sn5 imcs; and (b) (ni, cu)3sn4 imcs on the fracture surface. from publication: influence of interfacial intermetallic growth on. Results showed that the intermetallic compounds (imcs) exhibited a cu content dependent transformation from the (ni,cu)3sn4 phase to the (cu,ni)6sn5 phase at the ni xcu sn interface.

Eds Analysis Result Of A Sn B Cu 6 Sn 5 C Ag 3 Sn And D These mapping analysis results clearly show the existence of ni atoms and their incorporation into the interfacial imcs. the edx analysis of the interfacial imc revealed the presence of a (cu,ni) 6 sn 5 imc containing some substitutional ni in its lattice, which was found to be composed of approximately 33 at.% cu, 22 at.% ni, and 45 at.% sn. 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. (a) highly magnified cross sectional micrographs and p mapping of the interface between (cu,ni,pd,au)6sn5 and enepig pcb, and (b) schematic diagram of sequential (cu,ni,pd,au)6sn5 imc growth fig. 9. comparison of ni–sn–p ni3p thickness and drop reliability of various hybrid solder joints on enig pcb: (a) reflow jo ur na l p re p ro of journal pre proof soldering and (b) ipl. Abstract ni barrier symmetry effect on the electromigration (em) failure mechanism of cu sn–ag microbump were systematically investigated by studying the intermetallic compound (imc) growth characteristics at 150 °c with a current density of 1.5 × 105 a cm2. in the symmetric ni barrier structure, cu diffusion to sn–ag solder was restricted by the ni barrier at both interfaces and the.

Abstract ni barrier symmetry effect on the electromigration (em) failure mechanism of cu sn–ag microbump were systematically investigated by studying the intermetallic compound (imc) growth characteristics at 150 °c with a current density of 1.5 × 105 a cm2. in the symmetric ni barrier structure, cu diffusion to sn–ag solder was restricted by the ni barrier at both interfaces and the. The effect of nickel metallization thickness on microstructure evolution and mechanical properties in sn3.0ag0.5cu au ni cu solder joints was investigated here. first, a single layer cu–ni–au–ag–sn imc formed at the interface after reflow and then differentiated into double layers during solid state aging in both 3 μm nickel metallization (s1) and 6 μm nickel metallization (s2. According to eds analysis, the imcs were (cu,ni) 6 sn 5 . the effect of cross interaction due to the cu diffusion became weaker and as a result the (cu,ni)6sn5 phase formed on the ni side was.
