  • Publication number: 20240145268
    Abstract: A molding apparatus for fabricating a semiconductor package includes an upper mold including an upper cavity, a first side cavity at a first side of the upper cavity, a second side cavity formed at an opposite second side of the upper cavity, and a first driving part connected to the first side cavity and configured to move the first side cavity in a first direction, and a bottom mold including a bottom cavity configured to receive a molding target including a package substrate and at least one semiconductor chip. A width in the first direction between the first side cavity and the second side cavity may be smaller than a width of the package substrate in the first direction and greater than a width in the first direction between a first boundary and a second boundary of the at least one semiconductor chip.

  • Patent number: 11955359
    Abstract: The present disclosure provides a magazine supporting equipment for supporting a magazine with multiple input ports. The magazine supporting equipment comprises a contact plate, a first sidewall plate, and a second sidewall plate. The contact plate is in contact with the magazine. The first sidewall plate extends vertically from one end of the contact plate. The second sidewall plate parallel is to the first sidewall plate and extends vertically from one end to the other end of the contact plate. The first sidewall plate extends along at least a part of a first sidewall of the magazine. The second sidewall plate extends along at least a part of a second sidewall of the magazine. The first sidewall plate and the second sidewall plate include control openings through which gas flows in and out.

  • Publication number: 20240085469
    Abstract: A transmitting and receiving circuit may include a first CMOS inverter configured to receive a first power supply signal and a first input signal. The transmitting and receiving circuit may include a first calculation amplifier including a non-inverted input terminal connected to an output terminal of the first CMOS inverter, and a first resistor connected between the output terminal of the first calculation amplifier and a first node. The output terminal of the first calculation amplifier and an inverted input terminal of the first calculation amplifier may be connected to each other. A first output signal may have a level smaller than that of the first input signal and may be output to the first node.

  • Publication number: 20150325200
    Abstract: Provided are a source driver configured to drive a display panel and a display device including the same. A source driver configured to drive a source line of a display panel includes a digital circuit configured to receive and store digital pixel data, and an analog circuit configured to convert the stored digital pixel data into an analog-signal-type gradation voltage and output the analog-signal-type gradation voltage. A static current of the analog circuit is reduced in response to a value of a timing signal corresponding to a non-driving section of the display panel.
