Effects of Underfill Stiffness on Thermal Deformation of Solder Joint
Autor: Kunio Kokubo, Xu Luo, Eiji Hatayama, Masayoshi Tateno
Publikováno v: Journal of the Society of Materials Science, Japan. 61:119-124
The recent trend in circuit assemblies is to bond larger IC packages to PCB (Printed-circuit Board) by BGA (Ball Grid Array) solder joint and underfills. This would induce more intricate CTE (Coefficient of Thermal Expansion) mismatches among the PCB

Improving Reliability of Solder Joint by Means of Optimizing Underfill Properties
Autor: Masahide Mizoguchi, Xu Luo, Kunio Kokubo
Publikováno v: Journal of the Society of Materials Science, Japan. 59:699-704
The recent trend in electronics device towards bonding large chips to PCB boards by means of solder joint and intermingling with many others assistant materials, such as selectable underfills. This means a larger differential thermal expansion and de

Experimental and Numerical Analysis of the Fastening Bolt Using the Plastic Buckling Deformation of a Pipe
Autor: Kunio Kokubo, Kazuo Ichinose, Peizheng Lin, Masaaki Sakakuchi
Publikováno v: Journal of Solid Mechanics and Materials Engineering. 4:1765-1777
A one-sided fastening bolt using the plastic buckling of a pipe which is annealed along the length is studied in this paper. In fastening process the pipe is buckled to form a buckling head in the annealed area under an axial compressive load and the

Application of Plastic Buckling of Pipes with Flange to a Structural Fastening System
Autor: Kazuo Ichinose, Masazumi Yoshioka, Kunio Kokubo, Peizheng Lin, Masaaki Sakakuchi
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A. 70:749-755
One-sided fastening systems using plastic buckling of the thin-walled pipes with flange are studied in this paper. Plastic buckling occurs in the thin-walled pipe area of the blind nut with flange, when an axial compressive load is applied to the bli
