...Yi-Shao Lai; Ying-Ta Chiu; Chiu-Wen Lee Designed experiments were conducted in this paper to study the effect of Au/Ni/Cu or Cu substrate pad metallization on the electromigration reliability of 96.5Sn–3Ag–0.5Cu flip-chip solder joints with Ti/Ni(V)/Cu under bump metallurgy (UBM) under a current...

... micropart flows over a target wafer patterned with binding sites, which results in part-substrate attachment. This technique transports microparts from one location to another with orientation control and parallel sorting. The present study demonstrates a FSA approach for fast, economic, and precise...

...Yung-Shin Tseng; Tzu-Chen Hung; Bau-Shei Pei In this study, a computational fluid dynamics model has been developed to explain and validate the experimental results originating from the concept of a substrate with an opening. It is found that the openings will interrupt the growth of the boundary...

...Fang Liu; Guang Meng; Mei Zhao Dynamic properties of printed circuit board (PCB) assembly under drop impact are investigated when viscoelasticity of substrate materials is considered. The main materials of a PCB substrate are macromolecule resins, which are typical viscoelastic materials. From...

... processes and, therefore, their microstructures as well as the practical difficulties in measuring small temperature gradients during the characterization. In this paper, we will report on a novel film on substrate technique that can be used conveniently for repeated measurements of the lateral thermal...

... pitch applications. This work deals with adhesion issues between ACA on polyimide materials. The paper presents a reliability assessment of adhesive joints using ACA on polyimide substrate that was conducted by testing samples at various aging temperature, high humidity and high pressure environments...

...John H. Lau; Stephen H. Pan In this study, a three-dimensional (3D) nonlinear stress analysis of the tin whisker initiation on a pure matte Sn-plated copper substrate is investigated. The structure is subjected to a compressive stress acting at the Sn layer which is generated by the spontaneous...

...Tapani M. Alander; Pekka A. Heino; Eero O. Ristolainen Electrically conductive substrates (i.e., metals) are often used in the mounting of semiconductor laser diodes. While metals offer a good electrical and thermal performance, they restrict the system integration due to lack of signal routing...

... S have Tg (ca. 190°C) on the mid-range, which is near to the BT substrate Tg; types H have lower Tg, which is from 120 to 140°C. The basic data sheet and process parameter of mold compounds applied in CSP package P S H Resin type Multi-Functions Multi-Functions Biphenyl...

...Anh X. H. Dang; I. Charles Ume; Swapan K. Bhattacharya This paper presents potential application of stainless steel (SS) as a base substrate material for large area multi-chip module-deposited (MCM-D) packaging. Preliminary results on via formation on SS substrates by laser drilling, dielectric...

...Anh X. H. Dang; I. Charles Ume; Swapan K. Bhattacharya Potential application of stainless steel (SS) as a base substrate material for a large area MCM-D packaging is reported in this paper. A test vehicle was fabricated using 0.008 in. thick and 12 in.×12 in. SS panel with laser drilled 0.01...
