Title: The influence of microstructure on the mechanical properties of solder

Abstract

Solder joints in microelectronics devices consist of low-melting solder compositions that wet and join metal contacts and are, ordinarily, used at high homologous temperatures in the as-solidified condition. Differences in solidification rate and substrate interactions have the consequence that even solder joints of similar compositions exhibit a wide range of microstructures. The variation in microstructure causes a variation in properties; in particular, the high-temperature creep properties that govern much of the mechanical behavior of the solder may differ significantly from joint to joint. The present paper reviews the varieties of microstructure that are found in common solder joints, and describes some of the ways in which microstructural changes affect mechanical properties and joint reliability.

    Two-phase Ni-Al{sub 2}O{sub 3} microstructures were formed in situ by the partial reduction of NiAl{sub 2}O{sub 4} spinel at 1100{degrees}C and 1300{degrees}C. The influence of doping with Cr{sub 2}O{sub 3}, MgO, TiO{sub 2} and Y{sub 2}O{sub 3} on the microstructure and properties of these composites was examined. The dopants had no significant effect on the microstructure, of the composites except for TiO{sub 2}. Elongated Ni and {alpha}-Al{sub 2}O{sub 3} grains were present close to the reduction front and equiaxed Ni and {alpha}-Al{sub 2}O{sub 3} grains were located far from the reduction front in the TiO{sub 2}-doped samples formed at 1300{degrees}C.more » At 1100{degrees}C, the Ni and {alpha}-Al{sub 2}O{sub 3} equilibrium phases were formed in a very short time in the TiO{sub 2}-doped samples (<2hours) compared to the others (>100 hours), and many small pores were present in the Al{sub 2}O{sub 3} grains. Ti and Y segregation was found at the nickel-alumina interfaces in the doped composites. The Young`s modulus depended more strongly on the porosity than on the different dopants. The fracture toughness of the undoped and doped composites were similar, except for TiO{sub 2}-doped specimens which had lower values. The influence of TiO{sub 2} doping on the microstructure and mechanical properties of the Ni-Al{sub 2}O{sub 3} composites is discussed.« less

    Results of room- and elevated-temperature tensile and creep tests are reported from tests conducted on three heats of Modified 9Cr-1Mo steel. The heats were thermally aged at various temperatures from 482 to 704[degrees]C and at aging times to 75,000 h (8.6 years). Tensile strain rates were also varied in order to determine strain rate sensitivity of tensile properties. Changes in the yield and tensile strengths occurred following exposure to these temperatures with decreases noted at the higher temperatures. The material showed a strain-rate sensitivity particularly at temperatures in excess of about 538[degrees]C due to the presence of what was believedmore » to be strain aging. The tensile-strength data were parameterized in order to permit estimates of changes in both room- and elevated-temperature properties to be made following exposure for prolonged periods in service time. Estimates are given of the changes in yield and tensile strengths following isothermal exposure at several temperatures for 60 years of service. Observations are presented concerning microstructural and microcompositional changes as observed by conventional and transmission, analytical electron microscopy, and quantitative precipitate extraction.« less

    Solidification of eutectic Sn-Ag solder, with and without Cu{sub 6}Sn{sub 5} composite reinforcements, on copper substrates, was investigated at two different cooling rates. The size, orientation, randomness, and overall morphology of the dendritic microstructure were examined as a function of cooling rate. Cu{sub 6}Sn{sub 5} particle reinforcements were found to act as nucleation sites for dendrites, in addition to sites on the substrate/solder interface. The mechanical properties of these solders were also examined as a function of cooling rate. Solder joints with a lower load-carrying area were found to exhibit higher shear strength, but reduced ductility when compared to soldermore » joints with more load carrying area.« less
