    摘要: A bonding apparatus is constituted by a bonding tool, a substrate stage, a moving mechanism for moving the bonding tool and the substrate stage, an up-and-down mechanism for moving up and down said bonding tool, and a chip recognition camera. The bonding apparatus is configured so that a chip and a substrate are subjected to positioning on the basis of a recognition result of the chip recognition camera so that the chip is bonded onto the substrate. The chip recognition camera is disposed to be lower than a level of a substrate mounted surface of the substrate stage. A lower surface of the chip is recognized in a condition that the lower surface of the chip is located to be substantially on a level with a chip bonding surface of the substrate. Positioning of the chip and the substrate is performed by the recognition image.

    摘要: A ball grid array electronic package is attached to a substrate by means of solder balls and solder paste. Connection is made between a contact on the ball grid array and a solder ball by means of a first joining medium, such as a solder paste. Connection is made between a solder ball and a contact arranged on the substrate by means of a second joining medium. The contact arranged on the substrate is substantially quadrilateral in shape, and preferably substantially square in shape. Connection to the substrate, e.g., using round solder balls, is much more easily detected, e.g., by x-ray, than when using round pads, especially those having a smaller diameter than the balls.

    摘要: The invention provides a technique for evaluation of a spot welded portion by which the strength of a panel. In the evaluation method, a stress value at a welded portion of the panel is calculated by a stress analysis according to a FEM using the elements, and then the strength of the welded portion is evaluated based on the stress value at the welded portion. Particularly, a portion in the proximity of the spot welded portion is divided, with a central portion of the spot welded portion registered with a nodal point of the elements, into a central element and a plurality of concentric ring-like elements including first and second ring-like elements from the center side provided by the central portion of the spot welded portion. Thereafter, the plural concentric ring-like elements are individually divided in a circumferential direction each into a plurality of portions to form the elements. Then, the strength is evaluated based on the stress value of the second ring-like element.

    摘要: A process produces a welded seamless PIPE having good yield strength and excellent corrosion and/or erosion resistance. Up to a maximum outside diameter corrosion and/or erosion resistant CRA PIPE is cold worked from a welded hollow, rather than using the traditional seamless pierced hollow method. A high-speed roll-forming mill is also utilized, rather than using the slow traditional break press to form the welded hollow. Welded hollow dimensions can be achieved which comply with the method of cold working's capability to produce the yield strengths and dimensional tolerances required to meet the service criteria of the PIPE's intended application.

    摘要: A system and method having applications in semiconductor areas for accurate die placement on a substrate that takes into account any positional offset from the reference position due to variations caused by thermal change and other nonrandom systemic effects. The system includes an offset alignment tool having a plurality of internal reflection surfaces and located below a vision plane of the substrate, and an optical detector to receive an indirect image of a bottom surface of the die through the alignment tool, such that the die is accurately positioned on the substrate based on the indirect image received by the optical detector. The method comprises the steps of providing a cornercube offset alignment tool having a plurality of total internal reflection surfaces below a vision plane of the die, and receiving an indirect image of the die tool through the cornercube offset tool.
