  • Publication number: 20110088438
    Abstract: A low-power-consumption actuator for battery-powered electronic lock includes assembled first and second cases, the second case being provided at a top with a through bore; a piezoceramic/steel sheet assembly consisting of superposed first and second piezoceramic/steel sheet sets, a first end portion of the second piezoceramic/steel sheet set being in a free state; a circuit board electrically connected to the piezoceramic/steel sheet assembly; and a pin unit being located between a top of the first end portion of the second piezoceramic/steel sheet set and the through bore. When the circuit board applies a voltage across the piezoceramic/steel sheet assembly, the first end portion of the second piezoceramic/steel sheet set upward flexes and thereby displaces to push against the pin unit for a pin thereof to protrude from the through bore and interfere with a latch bolt of the electronic lock, so as to actuate the latch bolt.

  • Patent number: 7884472
    Abstract: A semiconductor package with a substrate ID code and its manufacturing method are revealed. A circuit and a solder mask are formed on the bottom surface of a substrate where the solder mask covers most of the circuit and a circuit-free zone of the substrate. A chip is disposed on the top surface of the substrate. A substrate ID code consisting of a plurality of laser marks is inscribed in the solder mask or in a portion of an encapsulant on the bottom surface away from the circuit to show the substrate lot number on the bottom surface. Therefore, quality control and failure tracking and management can easily be implemented by tracking the substrate ID code from the semiconductor package without changing the appearance of the semiconductor package. Furthermore, the substrate ID code can be implemented by the existing laser imprinting machines for semiconductor packaging processes and be formed at the same time of formation of a product code.

  • Patent number: 7792006
    Abstract: The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.

  • Patent number: 7786568
    Abstract: A WBGA semiconductor package primarily comprises a substrate, a chip, a chip-bonding adhesive, a plurality of bonding wires electrically connecting the chip and the substrate, an encapsulant to encapsulate the chip and the bonding wires, and a plurality of external terminals disposed under the substrate. The substrate has a depression for accommodating the chip-bonding adhesive and a slot for passing through bonding wires. The chip is partially embedded in the depression to dispose on the substrate. During the chip bonding step, the chip-bonding adhesive is confined in the depression in a manner to fill the gaps between the sides of the first chip and the inwalls around the depression to generate a non-planar adhering interface by partially covering the sides of the first chip. Therefore, the total package thickness is reduced, the delamination of the passivation layer and the fractures at the sides of the chip are avoided.

  • Publication number: 20100211659
    Abstract: A router and a method for avoiding the IP address conflict are disclosed. The method includes the following steps. First, once the router obtains an IP address as its WAN IP address, the network bits of the WAN IP address and the network bits of an IP pool of the router are retrieved. Then, it follows to determine whether the network bits of the WAN IP address is identical to that of the IP pool, and if yes, modify the network bits of the IP pool together with a LAN IP address of the router to be different from that of the WAN IP address. After that, an instruction is transmitted to the client terminals associated with the router. Upon reception of the instruction, the client terminals replace the old IP addresses with the new IP addresses assigned from the router in accordance with Dynamic Host Configuration Protocol.

  • Publication number: 20090243059
    Abstract: A semiconductor package structure includes a carrier having a plurality of leads, wherein each of the leads is composed of an inner lead and an outer lead; a chip arranged on the bottom surface of the inner leads; an electrical connecting structure and a molding component. The invention discloses that the inner leads are bent outwardly from the horizontal at top surface of the chip to form a ladder-like difference and the outer leads are extended outwardly horizontally, thus a height difference formed between the chip and the outer lead prevents the particles from contacting the chip and the outer lead at the same time to enhance the electrical reliability of the chip.

  • Publication number: 20090236710
    Abstract: A Chip-On-Lead (COL) semiconductor package is revealed, primarily comprising a plurality of leadframe's leads each having a carrying bar, a finger and a connecting portion connecting the carrying bar to the finger. A chip has a back surface attached to the carrying bars and is electrically connected to the fingers by a plurality of bonding wires. Therein, at least one of the bonding wires overpasses one of the connecting portions without electrical relationship. An insulation tape is attached onto the connecting portions in a manner to be formed between the overpassing section of the bonding wire and the overpast connecting portion so that electrical short can be avoided during wire-bonding processes of the COL semiconductor package. Therefore, the carrying bars under the chip have more flexibility in the layout design of COL semiconductor packages to use die pad(s) with smaller dimensions or even eliminate die pad.

  • Patent number: 7564123
    Abstract: A semiconductor package primarily comprises a plurality of leadframe's leads, a chip, a paddle, an adhesive and an encapsulant encapsulating the components mentioned above. The paddle has a carrying surface and an exposed external surface. The first chip is attached to one surface of the leads. The paddle is attached to an opposing surface of the leads by the adhesive bonding the carrying surface to the leads. Furthermore, the adhesive further encapsulates the gaps between the leads without contaminating the exposed external surface and with the exposed external surface exposed from the encapsulant. Therefore, the leads obtain a better support so that the encapsulated portions of the leads will not shift nor expose from the encapsulant during molding processes without encapsulated bubbles between the leads and the paddle. The heat dissipation is also enhanced.
