  • Patent number: 6483039
    Abstract: A substrate of a semiconductor package is proposed, which is formed with a strip copper layer on a core layer of the substrate, wherein a solder mask is arranged to cover the core layer and two lengthwise sides of the copper layer by a width between 0.1 mm to 1.0 mm, while a surface between the sides of the copper layer is exposed by forming a groove opening to the atmosphere and plated with gold. This makes bulges generated by shrinkage of the solder mask covering the sides of the copper layer extend outwardly in a direction away from the groove opening, allowing clamping force to be sufficiently exerted on the substrate by a mold during an encapsulation process. As such, after completing the encapsulation process, an encapsulating resin remained in the runner can be easily removed without damaging the substrate, and also resin flash can be prevented from occurrence.

  • Patent number: 6455355
    Abstract: A modified SMT (Surface Mount Technology) process is proposed for mounting an exposed-pad type of semiconductor device over a PCB (printed circuit board), which can help prevent the problem of floated soldering of the semiconductor device over the PCB. By this modified SMT process, a plurality of via holes are formed in the pad-mounting area of the printed circuit board; and a solder material is pasted over the bottom end of each of the via holes. As the semiconductor device is mounted in position over the printed circuit board, a solder-reflow process is performed on the pasted solder material so as to cause the pasted solder material to be wetted to the entire surface of the solder-wettable layer in each of the via holes, thereby allowing the solder material to reflow to the upper end of each of the via holes where the reflowed solder is also wetted to the exposed die pad of the semiconductor device, thereby securely bonding the semiconductor device to the PCB.

  • Patent number: 6452268
    Abstract: An integrated circuit package having an encapsulating body with a flanged portion and an encapsulating mold for molding the encapsulating body are proposed. It is a characteristic feature of the proposed encapsulating mold that the encapsulating-body cavity formed in the upper mold further includes a constricted cutaway portion in the rim thereof. The constricted cutaway portion can be either uniform in thickness or formed in a multi-step staircase-like shape. During the molding process, the resin used to form the encapsulating body would flow into this constricted cutaway portion; and within the constricted cutaway portion, the resin would more quickly absorb the heat of the upper mold, thus increasing its viscosity and retarding its flowing speed. As a result, the resin would less likely to flash onto those surface parts of the substrate beyond the encapsulating body.

  • Patent number: 6451625
    Abstract: A method of fabricating a FCBGA (Flip-Chip Bal-Grid-Array) package with molded underfill is proposed, which is characterized by the forming of a mold-buffering opening in the solder mask at the exit of the vent hole in the substrate, wherein the mold-buffering opening is dimensioned to be greater in width than the inside diameter of the vent hole, so that during molding process when the encapsulation material infiltrates to the exit of the vent hole, it can be confined within the mold-buffering opening, thereby preventing it from flashing to nearby solder-ball pads. Since there would substantially exist no mold flash over the exposed surface of the solder mask and the solder-ball pads, the resulted FCBGA package would be assured in the quality of its outer appearance and the bonding between the solder-ball pads and the subsequently attached solder balls thereon.

  • Patent number: 6444248
    Abstract: The present invention relates to apparatus and method for forming a proteinaceous emulsion or batter into shaped food products such as sausages without the use of a casing. A supply of suitable proteinaceous emulsion is provided and such emulsion is conveyed under pressure into an elongated hollow stuffing tube to form a continuous length of shaped emulsion. Thereafter the shaped emulsion is directed into a molding tube which is slideably mounted about the stuffing tube. As the emulsion enters the molding tube, the pressure of the emulsion causes the molding tube to move away from the stuffing tube. A treating fluid, such as a diluted food grade acid, is directed to the interior surface of the molding tube at about the point where the emulsion first enters the molding tube. The treating fluid is directed to the interior of the molding tube in such a manner that the interior of the molding tube is continuously wetted by the treating fluid as the molding tube moves relative to the stuffing tube.
