Patent number: 6169412Abstract: An adjustable tooling pin for a bed-of-nails test fixture used for testing circuit boards (cards) is provided which allows the tooling pin, and thus the card, to be precisely realigned while the card is still mounted in the test fixture. The adjustable tooling pin mechanism comprises a pivot bushing having a channel running from end-to-end into which a slide bar fits. The tooling pin projects from the end of the sliding bar in the z-direction such that a card may be located over the tooling pin. A locking screw fits through an aperture in the sliding bar and the pivot bushing and is threadably engaged into a threaded insert in the test fixture top plate. Hence, the tooling pin, and thus the card, are radially adjustable in the x-y plane by turning the pivot bushing and by sliding the sliding bar along the pivot bushing channel.Type: GrantFiled: January 4, 1999Date of Patent: January 2, 2001Assignee: International Business Machines CorporationInventor: Rodger A.

Patent number: 6141325Abstract: The invention provides a method for improving network routing calculations for routing data packets or connections between two points in a network through many incompatible sub-networks. Each node in the network comprises a plurality of agents, written in migrating executable code, which represent each sub-network or domain in the overall network. Hence, an originating node wishing to send data over the network need not concern itself with the topology of the links or communicate directly with other sub-networks. Instead, the originating node can calculate a path through the network locally, simply by querying its agents. Hence, this paradigm is based on an object-oriented design, in which the network controller (NC) at one node does not attempt to interpret topological data of a different node or sub-network. Instead, a network controller at the originating node activates the agents which represent the other sub-networks, and queries the agents (a black-box approach).Type: GrantFiled: December 18, 1996Date of Patent: October 31, 2000Assignee: International Business Machines CorporationInventor: Ornan Alexander Gerstel

Patent number: 6137299Abstract: 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.Type: GrantFiled: June 27, 1997Date of Patent: October 24, 2000Assignee: International Business Machines CorporationInventors: Robert R.
