    Feasibility of Copper-Base Leadframe Preplated with a Cu-Sn Alloy instead of Ni (2007)

    Notes: A preplated frame (PPF) consisting of Au/Pd/Cu-Sn/Cu substrate, i.e., preplated with aCu-Sn alloy instead of Ni commercially used, was fabricated by electroplating and then thefeasibility of the frame as an alternative PPF was investigated. The wettability of the Cu-Sn alloywas better than that of Ni, resulting in excellent contact with the substrate and smoother surface onthe upper Au/Pd protective layer. By XPS analyses, it was confirmed that Cu atoms in the Cu-Snalloy layer did not diffuse through the thin protective layer to the surface at temperatures used in ICassembly. The wire pull-strength and solderability of the Cu-Sn alloy PPF were almost equivalentto those of the Ni PPF. However, the former showed much better corrosion resistance than the latter

    An introduction to a garment technical drawing system and its DB construction methodology (2002)
    Bingley : Emerald
    International journal of clothing science & technology 14 (2002), S. 247-250

    Notes: A garment technical drawing system and its database construction methodology is introduced in this paper. The system consists of an application program and a modulized database system. The advantage of this system is that it is possible to construct a garment's partial technical drawing easily using this database system, and it enables the combination of any part of drawing stored in the database.

    Notes: Focuses on Korean garment manufacturing and the feasibility and benefits of introducing an expert system. Reviews previous literature on knowledge-based system and describes in detail the stages followed in developing, constructing, testing, evaluating, integrating, implementing and maintaining the expert system. Concludes that an expert system could be used to solve various garment manufacturing problems and would contribute to garment quality improvement through a standardized apparel production process.

    A new evaluation of seam pucker and its applications (1997)

    Notes: The AATCC grades of seam pucker do not provide sufficient information for analysing and solving the problems. Develops a new measurement system which redefines seam pucker with shape parameters and evaluates it using artificial intelligence. New standards of seam pucker with five shape parameters were developed. Shows that prediction and optimization for seam pucker are possible using these means. The system has already been employed in men's suit manufacture.

    Properties of Nd-Fe-B Magnetic Powder Prepared by Reduction-Diffusion Process Using a Spray-Dried Precursor (2004)

    Notes: Effect of washing step in R-D process on the structure and magnetic properties of Nd-Fe-Bpowder fabricated by the process using a spray-dried precursor was investigated. Although thepowder washed in water contained much more residual CaO than that washed in dilute acetic acid,magnetic properties of the former were much better than those of the latter due to less removal ofNd-rich phase. In the powder washed in water Nd2Fe14B particles were enclosed with thin layer ofNd-rich phase, and each particle consisted of one or more subgrains of the size 50 ~ 100 nm or more.Milling the powder before water washing was effective to remove more CaO, thereby increased theremanence of the powder

    Characterization of Iron and Its Nitride Nanoparticles Prepared by CVC Process without Using a Chiller (2005)
    s.l. ; Stafa-Zurich, Switzerland
    Materials science forum Vol. 486-487 (June 2005), p. 518-521 
    Details
    ISSN: 1662-9752

    Notes: Iron and its nitride (e-Fe3N) nanoparticles were fabricated by the CVC using Fe(CO)5 precursor without the aid of LN2 chiller. The iron particles synthesized at 400 oC were a mixture of amorphous and crystalline a-Fe. Fully crystallized iron particles were then obtained above 600 oC. Iron-nitride particles that were easily formed at 500 oC at 1 atm., however, were not fully developed in vacuum unless the reaction temperature reached 850 oC. Nevertheless, the work chamber needed to be maintained in vacuum to obtain finer iron-nitride particles. The synthesized particles possessing the core-shell type structure were all nearly spherical and enclosed with Fe3O4 or Fe3O4-related amorphous layer. The iron nanoparticles (~20 nm) synthesized at 600 oC at 760 torr exhibited iHc ~ 1.0 kOe and Ms ~ 170 emu/g, whereas the iron-nitride particles (~20 nm) synthesized at 850 oC at 0.01 torr exhibited iHc ~ 0.45 kOe and Ms ~ 115 emu/g
