  • Publication number: 20220084849
    Abstract: The technology of this disclosure relates to a chip packaging apparatus. The chip packaging apparatus includes a first differential pin pair, a first pin, and a second pin. The first differential pin pair includes a first differential signal pin and a second differential signal pin. In addition, the first pin and the second pin are both located between the first differential signal pin and the second differential signal pin, and the first pin and the second pin are differential signal pins (or both are power pins). The first pin is adjacent to the first differential signal pin and the second differential signal pin. The second pin is adjacent to the first differential signal pin and the second differential signal pin. The first pin and the second pin are respectively located on two sides of a first imaginary straight line connecting the first differential signal pin to the second differential signal pin.

  • Publication number: 20180247880
    Abstract: This application provides a chip packaging system, including multiple chips, a substrate, a heat dissipating component, and at least one thermoelectric refrigeration chip. A heat dissipating ring and a heat dissipating lid are provided on the heat dissipating component. One end of the heat dissipating ring is secured to the substrate, and the other end, opposite to the end secured to the substrate. The multiple chips are disposed in space enclosed by the substrate, the heat dissipating ring, and the heat dissipating lid, and all of the multiple chips are separated each other by using a thermal insulation material or by air. One surface of each of the at least one thermoelectric refrigeration chip is a hot end and the other surface thereof is a cold end. The cold end of each thermoelectric refrigeration chip is disposed on a side close to the multiple chips.
