    摘要： A semiconductor component (31) and a method for coupling a semiconductor device (36) to a substrate (81). The semiconductor component (31) includes a saddle (34) and the semiconductor device (36). The saddle (34) has a plurality of sides (51, 52, 53, 54, 55) that form a semiconductor device receiving area (58). The semiconductor device (36) is inserted into the semiconductor device receiving area (58) and secured in the semiconductor device receiving area (58) using tabs (66, 67). The saddle (34) is coupled to the substrate (81) by fasteners (82,83).

    摘要： A collapsible suitcase wherein a bottom member has side walls foldably secured thereto with slide fasteners connecting each side wall to form a box-like enclosure. The pull rings of the slide fasteners are locked in closed position by a latch on each corner of an attachable top. The actual volume of the case can be varied according to the extent the slide fasteners are zippered. Rollers are mounted under the bottom of the case to facilitate transport.

    摘要： A method of forming a dual port pressure sensor includes forming a first opening and a second opening in a flag of a lead frame. An encapsulant is molded to hold the lead frame in which the encapsulant is over a top of the flag and a bottom of the flag is uncovered by the encapsulant. A first opening in the encapsulant is aligned with and larger than the first opening in the flag and a second opening in the encapsulant aligned with the second opening in the flag. A pressure sensor transducer is attached to the bottom of the flag to cover the first opening in the flag, wherein the pressure sensor transducer provides an electrically detectable correlation to a pressure differential based on a first pressure received on its top side and a second pressure received on its bottom side. An integrated circuit is attached to the bottom of the flag. The integrated circuit is electrically coupled to the pressure sensor. A lid is attached to the encapsulant to form an enclosure around the bottom of the flag. The pressure sensor transducer receives the first pressure through the first opening in the encapsulant and the first opening in the flag and the second pressure through the second opening in the encapsulant, the second opening in the flag, and the enclosure.

    摘要： An overmolded pressure sensor package is provided. The pressure sensor die (Pcell) is capped so that the Pcell has enhanced rigidity to withstand stress effects produced by the molding encapsulant. The Pcell cap includes a hole located away from the Pcell diaphragm, so that external gas pressure can be experienced by the Pcell, while at the same time directing moisture away from the diaphragm. Gel does not need to be used, and instead a soft film can be deposited on the Pcell to protect the Pcell diaphragm from excess moisture, if needed. The Pcell cap can take the form of, for example, a dummy silicon wafer or a functional ASIC.
