Abstract:
A non-volatile memory module for preventing system failure and a system including the same, in which the non-volatile memory system includes a first socket and a second socket each having a notch coupler, a first memory module, a memory controller configured to control the first memory module, and a printed circuit board on which the memory controller and the first and second sockets are installed and electrical signal lines are formed between the memory controller and the first and second sockets. The first memory includes a plurality of non-volatile memory devices and stores system software. The first memory module has a structure such that it can be installed at the first socket but cannot be installed at the second socket. The non-volatile memory system may further include a second memory module for an extension of the memory capacity. The second memory module has a structure such that it can be installed at the second socket but cannot be installed at the first socket. Accordingly, system failure caused by misusage of a non-volatile memory module can be prevented.
Abstract:
A method for fabricating a multi-piece board includes: preparing a board main portion having a first coupling member and multiple piece portions connected to the first coupling member, the first coupling member forming a part of a coupling member of a multi-piece board, each of the piece portions having a printed wiring board; preparing a second coupling member which forms the coupling member together with the first coupling member; and adhering the second coupling member to the first coupling member of the board main portion, thereby yielding the multi-piece board.
Abstract:
A backlight assembly and a display device having the backlight assembly are provided where the backlight assembly includes a plurality of light sources for emitting light and a plurality of metal core printed circuit boards on which the light sources are mounted. The metal core printed circuit boards are directly connected to each other in predetermined regions to emit light in a surface direction. A method of assembling the backlight assembly is further provided.
Abstract:
A method is provided for making an encapsulated stack of circuit boards. The method includes assembling the stack of circuit boards from a plurality of circuit boards, the circuit boards being spaced apart from each other; inserting the stack into an internal volume of a shell, the shell having a first end and a second end opposite the first end, an input orifice adjacent the first end, and an output orifice adjacent the second end and on a side opposite the input orifice; positioning the shell such that the input orifice is at a lowest point of any part of the internal volume of the shell, and such that the output orifice is at a highest point of any part of the internal volume of the shell; angling the shell relative to horizontal; and injecting an encapsulating compound into the input orifice to fill the internal volume of the shell with the encapsulating compound.
Abstract:
