摘要： A separable and reconnectable connection for electrical equipment is provided that is suitable for miniaturization in which vertical interdigitating members integrally attached and protruding from a planar portion are accommodated in control of damage in lateral displacement that occurs on mating with an opposite similar contact. Displacement damage is averted through accommodating lateral stresses by providing one or more of a conformal opposing contact, by strengthening through coating and base reinforcement and a deformable coating. The contacts are fabricated by physical and chemical processes including sputtering, normal and pulse electroplating and chemical vapor deposition. Pulse electroplating of palladium provides a dendritic deposit of uniform height, uniform rounded points and less branching. The contacts on completion are provided with a surrounding immobilizing material that enhances rigidity.

摘要： A method of flip chip bonding an integrated circuit chip to a chip carrier. A high melting temperature composition, such as a binary Pb/Sn alloy, is deposited on contacts on, for example, the chip, and constituents of a low melting composition, such as Bi and Sn, are codeposited on contacts on, for example, the chip carrier. The chip and chip carrier are then heated. This causes the lower melting temperature composition, for example the Bi and Sn, to melt and form a low melting temperature alloy, such as a Bi/Sn alloy. The low melting alloy dissolves the higher melting composition, as Pb/Sn. This results in the formation of a solder bond of a low melting point third composition, such as a ternary alloy of Bi/Pb/Sn.

摘要： A method and apparatus for testing semi-conductor chips is disclosed. The individual semiconductor chips have I/O contacts. The apparatus is provided with an interposer that has contacts corresponding to the contacts on the semiconductor chip. Both the chip and the interposer contacts can be any known type including metal ball, bumps, or tabs or may be provided with dendritic surfaces. The chip contacts are first brought into relative loose temporary contact with the contacts on the interposer and then a compressive force greater that 5 grams per chip contact is applied to the chip to force the chip contacts into good electrical contact with the interposer contacts. Testing of the chip is then performed. The tests may include heating of the chip as well as the application of signals to the chip contacts. After testing the chip is removed from the substrate.

摘要： Electrically conductive lamina are attached by an electrically insulating, thermally conductive adhesive and/or solder to one or more semiconductor devices such as chips and extend beyond the periphery of the chip or chips to form heat sink fins. Electrical connections may be made between such chips through holes (e.g. by a wire or plated through hole) in the electrically conductive lamina lined with an insulating material such as the electrically insulating adhesive to provide a structurally robust assembly. Surface pads and connections may overlie patterns of insulator on the lamina. A further lamina can be wrapped around lateral sides of the assembly to provide further heat sink area and mechanical protection for other heat sink fins. A graphite/carbon fiber composite matrix material is preferred for the lamina and the coefficient of thermal expansion of such materials may be matched to that of the semiconductor material attached thereto. Conductivity of the lamina also provides shielding against electrical noise to improve the noise immunity of short connections between chips made through the lamina as well as that of surface connections which may be formed on the lamina.
摘要翻译： 导电层通过电绝缘的导热粘合剂和/或焊料附着到一个或多个半导体器件如芯片上并延伸超过芯片或芯片的周边以形成散热片。 电连接可以在这样的芯片之间通过衬有绝缘材料（例如电绝缘粘合剂）的导电层中的孔（例如通过导线或电镀通孔）形成，以提供结构上坚固的组件。 表面焊盘和连接可能覆盖层的绝缘体图案。 另外的层可以围绕组件的侧面缠绕以提供进一步的散热器区域和用于其它散热片的机械保护。 对于层板优选石墨/碳纤维复合材料基体材料，并且这种材料的热膨胀系数可以与附着于其上的半导体材料的热膨胀系数匹配。 薄层的电导率还提供了防止电噪声的屏蔽，以提高通过薄片制成的芯片之间的短连接的抗噪声能力以及可能形成在薄片上的表面连接。
