  • Patent number: 11938660
    Abstract: A mold die includes: a mold die body that is configured to hold an object to be molded, the object including a substrate and a chip mounted in a central area of the substrate, and that has a cavity which is rectangular in a plan view and which is configured to receive a resin material, the mold die body including: a pot for containing the resin material; a gate disposed at one side of the cavity and configured to allow the resin material to flow into the cavity; and a flow-path restricting mechanism that is disposed on both lateral sides of the cavity that are perpendicular to the one side and that is configured to narrow lateral flow paths, the lateral flow paths being flow paths for the resin material flowing through the cavity in which the chip is not disposed.

  • Publication number: 20230382027
    Abstract: A resin molding apparatus includes: a mold die that is configured to hold an object to be molded, the object including a substrate and a chip on the substrate, and that has a cavity configured to receive a resin material through a gate; a mold clamp mechanism configured to clamp the mold die; and a control section configured to control how the mold die and the mold clamp mechanism are operated, the mold die including: a movable block configured to narrow at least a portion of an internal flow path of the cavity in which internal flow path the chip is not disposed; and a driving mechanism configured to drive the movable block with use of a fluid, the control section being configured to change a driving force of the driving mechanism during resin-molding of the object.

  • Patent number: 6082161
    Abstract: In a stabilization control of rolling, proportional differential control of snake motion of a to-be-rolled material caused during a rolling process, is achieved on the basis of a lateral deviation of loads which are detected by load sensors disposed on a rolling mill, an instruction value for lateral deviation leveling is calculated from the lateral deviation and given to a draft device, and a roll gap is adjusted on the basis of the instruction value to stabilize the snake motion of the to-be-rolled material. A stabilization low-pass filter having a pole time constant substantially equal to a zero-point time constant of operation frequency characteristics of the rolling mill is employed in the proportional control.
