Abstract: The present invention provides a chip packaging structure and a chip packaging method. Compared with an existing method of joining an encapsulation layer with a dielectric layer, adhesion between the encapsulation layer and a chip in the present invention is increased, and the encapsulation layer is less likely to fall off under stress. Furthermore, during the packaging process, a passivation layer enables chips to be mutually fixed together, which can prevent the chips from being shifted during the encapsulation process, and thereby enhance the reliability of the final product and improve the yield of the final product.

Abstract: The present invention provides a wafer-level fan-out structure and a manufacturing method thereof. The wafer-level fan-out structure includes a plurality of chips, a sheet-like structure and a plastic packaging layer. The plastic packaging layer covers the plurality of chips and the sheet-like structure. The sheet-like structure includes a first region and a second region. The first region includes a plurality of spaced apertures, and each aperture is adjacent to the second region. The plurality of chips and the plurality of apertures are in one-to-one correspondence, and each chip is located in the corresponding aperture. A Young’s modulus of the plastic packaging layer is smaller than that of the sheet-like structure, and a ratio of an area of the first region to an area of the second region is (0.5-2):1. The wafer-level fan-out structure can remarkably reduce package warpage and achieves better package strength.

Abstract: This invention relates to magnetocaloric materials comprising alloys useful for magnetic refrigeration applications. In some embodiments, the disclosed alloys may be Cerium, Neodymium, and/or Gadolinium based compositions that are fairly inexpensive, and in some cases exhibit only 2nd order magnetic phase transitions near their curie temperature, thus there are limited thermal and structural hysteresis losses. This makes these compositions attractive candidates for use in magnetic refrigeration applications. Surprisingly, the performance of the disclosed materials is similar or better to many of the known expensive rare-earth based magnetocaloric materials.

Abstract: Aiming at insufficient drying seafood on-board caused by hull swings, the present invention involves the establishment of location correction system for processing seafood transportation displaced by wind waves and anti-accumulation drying processing method. This invention employs CFD-DEM method to simulate the state and distribution of the material particles modulated by the deflector angle and wind speed. Finally, the optimized rotation angle of deflector and wind speed are obtained where material particles are equally distributed. Meanwhile, the uniform and fast drying of the marine products in the swinging hull are achieved. This invention shows the great advantages of high efficiency, automation and continuity.

Abstract: The present invention provides a method for extracting heat-sensitive Antarctic krill oil comprising the following steps. Firstly, frozen Antarctic krill is thawed and minced; a surfactant is added to the minced Antarctic krill to form a supercritical micelle system; extract the Antarctic krill multiple times after pressurizing and liquefying mixed gases; at the same time, a low-carbon alcohol solvent is added to strip the material in the critical micelle; after the extraction is completed, the extractant is removed; the extraction product and the residue after the extraction are subsequently collected; the heat-sensitive Antarctic krill oil can be obtained by high-speed centrifugal separation of the oil-water mixed extraction product. The present method has the advantages of simple operation, low extraction pressure and high safety. The extraction method of gas pressure liquefaction is completed under low temperature sealing conditions.
