...-alignment occurs in controlled collapse bonding when the solder interconnects become liquidus and, driven by surface tension, pull the chip into registration with the substrate. To study flip chip self-alignment in the presence of underfill, the viscous forces acting on the chip during realignment...

...Satoru Katsurayama; Hironori Tohmyoh In flip chip packages, it is common practice for interconnects to be encapsulated with a liquid underfill material. This paper describes the effects of different underfill processes, i.e., the conventional capillary-flow underfill and two no-flow underfill...

... conductivity material. High Density Interconnection is accomplished either by direct printing of 75 micron conductor traces or, for smaller dimensions, conductive ink deposited in specially “patterned” dielectric. (1) Since the electronic device is securely held in the pocket by the moulded substrate...

..., with both step-function and sinusoidal temperature histories being considered. The time-dependent effects in the array’s shear deformation are introduced in an approximate manner by modeling the interconnect material (solder) as a temperature-independent linear viscoelastic material. The viscoelastic...

...Naotaka Tanaka, Senior Researcher; Kenya Kawano, Researcher; Hideo Miura, Chief Researcher; Yoshiyuki Kado, Engineer; Ikuo Yoshida, Senior Engineer The interconnection reliability of a contact-joint structure with anisotropic conductive film (ACF) or non-conductive film (NCF) was evaluated in terms...

... and the interconnection as a result of high energy impact on an electronic equipment. Shear test was then performed to examine the change in strength of the ICA joints as a result of impact damage. It was found that the SM ICA joints failed due to impact at a strain rate just over 4000/s. Microstructural examination...
