  • Publication number: 20240113032
    Abstract: Interconnect structure packages (e.g., through silicon vias (TSV) packages, through interlayer via (TIV) packages) may be pre-manufactured as opposed to forming TIVs directly on a carrier substrate during a manufacturing process for a semiconductor die package at backend packaging facility. The interconnect structure packages may be placed onto a carrier substrate during manufacturing of a semiconductor device package, and a semiconductor die package may be placed on the carrier substrate adjacent to the interconnect structure packages. A molding compound layer may be formed around and in between the interconnect structure packages and the semiconductor die package.

  • Publication number: 20240074119
    Abstract: An immersion cooling system includes a pressure seal tank, an electronic apparatus, a pressure balance pipe and a relief valve. The pressure seal tank is configured to store coolant. A vapor space is formed in the pressure seal tank above the liquid level of the coolant. The electronic apparatus is completely immersed in the coolant. The pressure balance pipe has a gas collection length. The first port of the pressure balance pipe is disposed on the top surface of the pressure seal tank. The relief valve is disposed on the second port of the pressure balance pipe. The second port is farther away from the top surface of the pressure seal tank than the first port. The gas collection length of the pressure equalization tube allows the concentration of vaporized coolant at the first port to be greater than the concentration of vaporized coolant at the second port.

  • Patent number: 9528582
    Abstract: An internal-circulation-type ball screw includes a nut, a screw shaft, and two returning members. The nut has an internal-thread groove. The screw shaft passes through the nut and has an external-thread groove. The internally and external-thread grooves are aligned to form a helix channel. The screw shaft has a returning channel and two opposite receiving recesses. Each of the receiving recesses is radially communicated between the external-thread groove and the returning channel. The returning members are received in the receiving recesses of the screw shaft and each have a redirecting channel. The redirecting channel is connected between the helix channel and the returning channel, so that balls are allowed to circulate along the helix channel, the redirecting channel and the returning channel. Thereby, the internal-circulation-type ball screw provides good durability, reliability and smoothness in use.

  • Publication number: 20130333482
    Abstract: A compression testing device includes a receiving unit and a pressing unit movable relative to the receiving unit. The receiving unit includes an outer housing, a sleeve inserted removably into the outer housing, and a liquid supplying mechanism. The liquid supplying mechanism is operable to force a culture medium to flow through the outer housing and the sleeve. A specimen unit is disposed removably within the outer housing. Due to the design of the liquid supplying mechanism, a compression test can be performed on the specimen unit, and cells can be cultured on the specimen unit. In this manner, relationship and change between the specimen unit and the cells can be observed in a real life simulating condition.
