Abstract: The present invention relates to a power module that is capable of decreasing the number of components and assembling man-hours by applying a metal clip and performing an integrated soldering process and is capable of keeping a thickness of a soldering part constant and preventing movement of chips at the time of soldering by using a soldering jig.

Abstract: Disclosed is a power module pack including a first cooling plate, a second cooling plate stacked on and coupled to the first cooling plate, and power modules interposed between the first cooling plate and the second cooling plate. Each of the power modules has a lower surface soldered to an upper surface of the first cooling plate.

Abstract: A bus bar assembly installed in a frame for fixing a plurality of stacked battery cells is provided. The bus bar assembly may include: a bus bar fixed to the frame; a flexible printed circuit board electrically connected to the bus bar and configured to sense the plurality of battery cells; and a connection terminal having a protrusion formed on one surface of the connection terminal, is the protrusion being configured to pass through the flexible printed circuit board so as to be electrically connected to the flexible printed circuit board, and the connection terminal configured to be electrically connected to the bus bar through the opposite surface of the one surface, the opposite surface being bonded to the bus bar.

Abstract: Provided is a flexible circuit board installed on a frame to which a bus bar is coupled. The flexible circuit board may include a central portion having a band shape, first connection circuit portions formed at both ends of the central portion and disposed to face each other, second connection circuit portions extending from the first connection circuit portions in parallel with the central portion, and third connection circuit portions extending from the first connection circuit portions and the second connection circuit portions and connected to the bus bar. An overlapped may be formed when each of the second connection circuit portions is folded toward one side of each of the first connection circuit portions.

Abstract: The present disclosure provides a reflective polarizer module characterized by comprising: a first light collecting sheet including a first structuring pattern having a first unit light collector, the cross-sectional area of which is reduced progressively upward, which is disposed continuously in a repetitive manner, and collecting a light transmitted from below; a reflective polarizer sheet disposed in a stacked configuration on the top of the first light collecting sheet, and selectively transmitting the light by having a plurality of stacked layers having mutually different refractive indices; and a light recycling improving sheet disposed at the bottom of the reflective polarizer sheet, and randomly changing the polarized direction of the light which is not transmitted through the reflective polarizer sheet but is reflected downward.
