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： Formation of a contact probe having a pattern of dendritic textured contacts complementary to that of a contact pad array on a bare chip allows formation of simultaneous temporary connections to all contact pads of the bare chip at a much reduced compressional force across the chip. The reliability of such connections at such a reduced force allows screening, burn-in and full functional testing of the bare chip at a high throughput by an automated apparatus to exploit potential economies of "known good die" (KGD) processing for limiting or avoiding repair, rework and further processing of less than fully functional chips for complex electronic packages. The compressional force is sensed by a pressure sensor, the output of which controls the advancement of the bare chip toward the contact probe such that the dendritic textured contacts of the contact probe penetrate the contact pads of the bare chip.

摘要： In pressure forming splines or teeth in the axially-extending sleeve of a clutch hub having a cylindrical oil seal surface adjacent the sleeve, a pair of special tooth-forming racks adapted to intermesh with a toothed mandrel with the sleeve therebetween and a pair of special support racks adapted to contact the oil seal surface are used. Each tooth-forming rack includes a first working surface with a plurality of toothed sections interrupted and spaced apart by toothless sections in an alternating sequence and each further includes a second working surface with uninterrupted toothed sections. Each support rack includes a first working surface with raised support sections interrupted and spaced apart by lower non-supporting sections in a proper alternating sequence and configuration to insure that the raised sections support the oil seal surface when the interrupted toothed rack sections of the tooth-forming racks deform the sleeve. A second working surface of the support racks includes a raised support section similarly adapted to support the oil seal surface during initial contact of the uninterrupted rack teeth of the tooth-forming racks with the sleeve. A clutch hub is thereby manufactured having a splined sleeve roundness within 0.025 inch and oil seal surface roundness within 0.006 inch.
摘要翻译：在具有邻近套筒的圆柱形油封表面的离合器轮毂的轴向延伸的套筒中形成花键或齿，一对特殊的成形齿条适于与齿形心轴与其间的套筒相互啮合，并且具有一对特殊的使用适于接触油封表面的支撑架。每个齿形齿条包括第一工作表面，该第一工作表面具有以无齿部分间隔开间隔的多个齿形部分，并且每个齿形部分还包括具有不间断齿形部分的第二工作表面。每个支撑架包括第一工作表面，该第一工作表面具有中间并且由下部不支撑部分以适当的交替顺序和构造间隔的凸起支撑部分，以确保当牙齿形状的中断的齿形齿条部分时，凸起部分支撑油封表面，成型架使套筒变形。支撑架的第二工作表面包括凸起的支撑部分，类似地适于在齿形齿条的不间断齿条与套筒的初始接触期间支撑油封表面。因此制造了具有0.025英寸内的花键套筒圆度和0.006英寸内的油封表面圆度的离合器毂。

摘要： In pressure forming splines or teeth in the sleeve of a clutch hub and the like, a rotatable toothed mandrel and a pair of sliding toothed racks are offset relative to one another such that when the sleeve of the clutch hub blank is placed on the mandrel, a ring-shaped lip portion of the sleeve adjacent the open sleeve end is not intermeshed between the mandrel teeth and rack teeth and thus is not splined and such that a transition region between the cylindrical oil seal surface and the sleeve is splined. The clutch hub thus includes splines on the sleeve terminating short of the open sleeve end in an unsplined ring-shaped lip portion and extending at the other end contiguous with splines formed in the transition region between the oil seal surface and sleeve. A clutch hub can thereby be manufactured having, in combination, a longitudinal tooth taper (bellmouth) within required close tolerances, e.g., within 0.010 inch, preferably within 0.005 inch, and an oil seal surface with roundness within required close tolerances, e.g., within 0.005 inch.
