  • Patent number: 8263870
    Abstract: It is an object to improve a conventional point that mounting an electronic component that requires a high current and heat radiation, such as an LED, together with other general electronic components on the same board has been difficult. To achieve this object, a different thickness lead frame partially having different thicknesses is used. On a thick portion of the different thickness lead frame, a special electronic component, such as an LED, for which a high current and heat radiation are required is mounted. Further, a thin portion of the different thickness lead frame is formed at a fine pitch, and general electronic components are mounted at a high density on the thin portion. Thus, unitization or modularization of electronic components for which a high current and heat radiation are required becomes possible.

  • Patent number: 6636429
    Abstract: A high frequency, low impedance network is integrated into the substrate level of a power module for the reduction of electromagnetic interference (“EMI”). In one embodiment, capacitance is electrically connected to at least one of the positive conducting layer in a substrate or the negative conducting layer in a substrate and a ground. Integrating a capacitive network of low stray inductance in a substrate of a power module allows relatively small, inexpensive capacitors to be used.

  • Patent number: 6614655
    Abstract: In an information processing apparatus such as a space-saving type personal computer having a liquid-cooling type cooling system, the presence of a cooling liquid, the presence of a frozen state of the cooling liquid and the temperature of the cooling liquid are detected. When a freeze of the cooling liquid is detected, a CPU is throttled down to defrost the cooling liquid, or the cooling liquid is heated to be prevented from being frozen. Alternatively, a warning of detection of a freeze may be displayed. Alternatively, activation of the system may be stopped or operation of the system may be interrupted. By such measures, system failure is prevented from being caused by leaking, shortage, freezing, etc. of the cooling liquid.

  • Publication number: 20030090877
    Abstract: The preferred embodiments provide a lead frame wherein a first air vent 29 and a second air vent 30 are formed in an air vent forming region 32. When resin-molding, one end of this first air vent 29 is disposed within the cavity, whereby air in the cavity when resin-molding can be completely released to the outside of the cavity. As a result, a package after resin-molding includes no unfilled regions or voids, whereby a semiconductor device with excellent product quality can be provided. In the background, air in cavities could not be completely released when resin-molding since, for instance, one air vent was provided at a position apart from the cavity region, and unfilled regions or voids were created.

  • Patent number: 6552420
    Abstract: A semiconductor device assembly package includes a semiconductor device having components thereon which are generic to a variety of applications by manipulation of the pinout configuration. The lead frame includes redundant leads for connection to the semiconductor device, as desired. The semiconductor device may include redundant wire bond pads, each redundant pair including one pad on a lateral edge and one pad on a non-lateral edge of the die. In applications requiring less than all of the available leads, the pinout configuration of the leadframe is adjusted to use the extra space from unused NC leads and missing pins for providing wider, shorter leads with reduced inductance, and wider paddle arms for reduced bending and breakage.

  • Patent number: 6552901
    Abstract: Apparatus and systems for cooling heat sinks, integrated circuit boards, and electronic components by providing internal passageways in the heat sinks, circuit boards, and electronic components that connect to a fluid manifold. The internal passageways connect to the surface of the heat sinks, circuit boards and electronic components. A cooling fluid capable of phase change is supplied to the internal passageways to conductively cool the interior of the heat sink, circuit board, and component and to cool the surface of the heat sink, circuit board, and/or component at least partially by evaporative cooling. A plurality of circuit boards, components, and/or heat sinks may be placed back to back with the fluid manifold therebetween. The heat sinks, circuit boards, and/or components are in an enclosed space so that cooling fluid can be contained, condensed and recycled to the fluid manifold.

  • Publication number: 20030072136
    Abstract: A lead frame of a circuit board is punched in a direction opposite to a heat sink plate. Even if burrs are produced due to the punching, the burrs do not penetrate a sheet or short-circuit to the heat sink plate. A resist film tightly contacts on the periphery of a land of the lead frame of the circuit board, and a plated layer tightly contacts on the land. This prevents electronic components from defective mounting on the land.

  • Patent number: 6545868
    Abstract: An improved multi-chip module includes a main circuit board having an array of electrical interconnection pads to which are mounted a plurality of IC package units. Each IC package unit includes a pair of IC packages, both of which are mounted on opposite sides of a package carrier. The package units may be mounted on one or both sides of the main circuit board. A first primary embodiment of the invention employs a laminar package carrier having a pair of major planar surfaces. Each planar surface incorporates electrical contact pads. One IC package is surface mounted on each major planar surface, by interconnecting the leads of the package with the contact pads on the planar surface, to form the IC package unit. A second primary embodiment of the invention utilizes a carrier substrate which has a pair of recesses for back-to-back surface mounting of the IC package pair. The two IC packages may be in contact with opposite sides of a heat sink layer embedded within the carrier substrate.
