Abstract: A novel silicon-based packaging platform with the electroplated-based reflector and the electrode- guided interconnections is developed for the packaging component of a high-luminosity and high-efficiency multi-chip light-emitting diode (LED) module, which is patterned on a new type of insulating layer that consists of nanoporous anodized aluminum oxide (AAO) layer and plasma- enhanced chemical vapor deposition (PECVD) deposited silicon dioxide (SiO2) on a doped silicon substrate. The reflector and the electrical interconnections are successfully fabricated by using the electroplating method in the same body. In order to obtain the benefits of high efficiency LED modules, the requirements concerning thermal management and photomechanical layout have to be met. In this paper, we will discuss a novel fabrication method in LED module packaging platform, and then describe the thin layer of electroplated Cu/Ni/Au in order to reduce thermal resistance and to increase thermal diffusion efficiency. The heat generated by the LED chips is dissipated directly to the silicon body through the metal-plated platform, and truly excellent heat dissipation characteristics are observed. We demonstrate 987 lm 8 W-level cool-white light (5000 K, 16 V, 110 lm/W, CRI = 77) emission for 570 µm × 230 µm-chip LEDs at 600 mA operation.

Abstract: Since the problems of environmental pollution and natural resource consumption have become worse, Packaging Industry should take its responsibility of protecting the environment. This article discussed about some serious problems caused by over packaging and made a research on some methodologies on reducing packaging. Among the 3R1D principles, the most important one is “Reduce”. Simplifying packaging could not only both directly save natural resources and reduce environmental pollution but also has a resounding ripple effect across the entire production phase. Through this way, the author tried to find some new solutions to minimize human’s impact to the environment.

Abstract: Cushion has a wide range of applications in engineering. It is a new attempt to use it in the field of printing and packaging lamination process, to get a numerical simulation study analyzes for the distribution of the formation pressure of the air cushion pressure chamber. On the basis of analysis of the principle of air-cushion laminated device, make it clear for the requirements of the air cushion pressure distribution, pressure distribution from a single stomatal mathematical model, using ANSYS finite element software, numerical simulation of multi-stoma pressure distribution. The results showed that: stomata arranged in the form of cushion thickness, stomatal spacing and stomatal row spacing uniformity of the distribution greater impact on the cushion pressure; small stomatal spacing and stomatal row spacing will help improve the air cushion pressure distribution uniformity; reasonable cushion thickness stomatal spacing and stomatal row spacing, the selected diameter of the pores smaller cushion pressure distribution uniformity.

Abstract: Today,bioplastics are becoming increasingly prominent owing mainly to scarcity of oil,increase in the cost of petroleum-based commodities,and growing environmental concerns with the dumping of non-biodegradable plastics in landfills. In this paper,we first discuss the definition and basic facts as well as the major advantages of bioplastics,then the main differences between plastics and bioplastics in packaging are reviewed. Finally,possible future developments of bioplastics are prospected.

Abstract: This paper describes evaluation of the strength in Ag-Sn-jointed Si specimens heated by Al/Ni film’s exothermic reaction. The reaction generates heat enough to melt Ag-Sn film for soldering. To measure the strength, four-point micro-bending test technique has been developed. The rectangular-solid Si specimens having a Ag-Sn/AlNi/Ag-Sn section were prepared by dicing the bonded Si-wafer under various pressure loads. A higher pressure yielded a better contact condition between Al/Ni and Ag-Sn so that heat-conduction improved; consequently Ag-Sn was melted sufficiently. Al/Ni reactive film has a potential as a micro-heater in soldering for MEMS.

Abstract: Chitosan solution was applied to coated ivory board as a barrier material, and the surface microstructure, oxygen resistance and water vapor permeability of chitosan-coated paper under different coating weight were studied. According to the images of scanning electron microscope(SEM) and Atomic force microscope(AFM), the coated ivory board surface has a smooth contour without pores and cracks after coating with chitosan. Increasing in coating hold-out of chitosan, the smoothness and the oxygen barrier properties of coated paper were improved considerably, but no improvement on water vapor resistance. An Oxygen transmission rate (OTR) of 119.0 cm3/m2•24h•0.1MPa was obtained when the coating weight of chitosan was 3.96 g/m2. Single-layer and double-layer techniques were used to coat coated ivory paper with chitosan; it was found that the OTR of paper, obtaining by double-layer coating technique, was lower than that of single-layer paper at similar coating weight. For the purpose of reducing water vapor transmission rate (WVTR) of chitosan-coated paper, Poly(vinyldene chloride)(PVDC) was applied on the chitosan-coated paper. Water vapor and oxygen barrier properties were enhanced as the coating weight of PVDC increased from 1.05 g/m2 to 7.40 g/m2. While the chitosan and PVDC was coated on coated ivory paper through bi-layer technique for 1.96 g/m2 and 7.40g/m2, respectively, the WVTR and OTR of paper decreased by 66.3% and 98.0% separately, compared to that of the chitosan-coated paper for 1.96g/m2.

Abstract: The waste production is increasing owing to an economical development of the society. In the area of a communal sphere they are namely PET (polyethyleneterephtalate) bottles. The research aim was to evaluate methods of compacting the drinking PET packaging. The plastic drinking packaging waste is distinguished for its dominant representation. Owing to its construction it takes up a front place in low efficiency of a storing and transporting space comparing with a material yield. The efficient compacting of the drinking packaging leads to solving a problem with often fulled up containers. The volume decreasing by means of the compacting of the packaging waste can be done in a few ways. A basic sortion is a manual pressing without the press, second way is using the mechanical presses. A low efficiency of the packaging materials is one of essential problems from the sustainable progress of human society point of view. Statistical methods were used for evaluating results and deducing conclusions. The most often used PET drinking packaging (the volume 0.5 l, 1.5 l and 2.0 l) was evaluated. The volume of the bottle before compacting and after it was set on the base of a level uplift in a calibrated laboratory tub coming from the Archimedes´s law. Experiment results showed that an effective compacting rate was reached by a manual press
