Patent number: 4996585Abstract: An electronic package (11) which comprises a substrate (12) having several chips (13) arranged thereon, and a plurality of connector pins (26) fitted in pin plates (21-24) and electrically connected via conductors to the chips (13). Each pin plate is mounted by means of at least one flexible connector element (29) connected to the conductors at a respective peripheral section (16-19) of the substrate (12). The pin plates have a base surface in the form of any discretionary polygon, in such a manner that, when folded, form a plane substantially flush with the plane of the substrate (12) into a position beneath the substrate (12), or vice versa. Thus an electronic package is obtained which is less complex in its manufacture and covers a considerably reduced base surface while offering a comparable performance.Type: GrantFiled: July 18, 1989Date of Patent: February 26, 1991Assignee: International Business Machines CorporationInventors: Harald Gruber, Kurt Hinrichsmeyer, Heinz G.

Patent number: 4969259Abstract: A compliant portion of the tubular body of a compliant pin is configured with an elliptical cross section. Preferably, the tubular body is seamless but alternatively may have a seam with the edges of the seam connected together. The configuration is particularly useful for micro-miniature pins. In the preferred method embodiment, on one side of a member to which the pin is to be affixed, the leading end of a blank tubular pin is inserted into the mating receptacle of the member and such that the blank pin provides a protrusion or extension on the opposite side of the member. A compliant section with an elliptical cross section if formed in a predetermined part of the protrusion and thereafter the pin is partially retracted into the receptacle so that the compliant section coacts with the receptacle to affix the pin to the member.Type: GrantFiled: December 14, 1988Date of Patent: November 13, 1990Assignee: International Business Machines CorporationInventors: Joseph S.

Patent number: 4814857Abstract: The present invention provides a pluggable, high density, reliable integrated circuit package. The package has a plurality of integrated circuit chips mounted on a multilayer ceramic substrate. Input-output signals are provided to the module by means of mating male female input-output pins which are located on the bottom of the module. Power is provided to the module from a multilayer ceramic frame through an edge connector that is an integral part of the mulltilayer ceramic substrate. Matching circuit vias located on the edge of the multilayer ceramic substrate and on the edge of the multilayer ceramic frame are cut and tinned with tin-lead to provide power input connections. When the module is plugged into the circuit board the edge connectors on the module mate with the edge connectors in the ceramic frame. Since the frame is made of the same material as the module substrate, the power connectors have excellent thermal match and they are highly reliable.Type: GrantFiled: February 25, 1987Date of Patent: March 21, 1989Assignee: International Business Machines CorporationInventor: George G.

Patent number: 4550493Abstract: A machine for forming a head and a bulge on a copper pin and to connect the pin to a ceramic substrate by a single application of impact force at high velocity and controlled energy conditions includes an air cylinder within which a piston of controlled mass moves due to the effect of compressed air stored in an accumulator. A die block includes a two dimensional array of holes into which are fitted pin blanks that extend above the surface of the die block and on which is fitted a substrate having an identical array of pin holes formed therein. The pins are fitted within the die block and on the substrate such that a predetermined length of the pin blank extends above the surface of the substrate and a controlled length of the pin blanks extends between the substrate and the die block. The pins are retained within the die against axial movement and the holes in the substrate and die block provide radial restraint to the pins following the application of the impact force.Type: GrantFiled: February 8, 1984Date of Patent: November 5, 1985Assignee: International Business Machines CorporationInventors: Russell E.

Patent number: 4544317Abstract: A vacuum-to-vacuum entry system which uses a rotary transport to transfer workpieces between two vacuum environments in a direction parallel to its axis of rotation and through the interface of a combination rotary gas bearing and seal. The combination gas bearing and seal seals off a zone in the gap between its two planar bearing surfaces that is radially offset from the axis of rotation of the bearing which is coincidental with the transport axis. Two arcuate gas sink channels on one of the bearing surfaces sink the gas of the bearing away from the zone. The bearing gas outside the zone in the gap and the two channels coact to effect a peripheral seal about the zone allowing the two vacuum environments when appropriately aligned to be in sealed communication with each other through the zone. A preferred embodiment is described for the transfer of ceramic substrates with circuitized surfaces between two vacuums environments.Type: GrantFiled: April 16, 1984Date of Patent: October 1, 1985Assignee: International Business Machines CorporationInventor: Donald L.

Patent number: 4436001Abstract: Stripping and cutting apparatus in which a pair of disc cutters are affixed on a common rotatable shaft that is pivotably mounted to a rotating head. An object having an inner core member and an outer concentric member, which in the preferred embodiment is insulated conductive tubing, is advanced through a central opening in the head. The speed of the head is controlled so that at one speed the shaft is centripetally pivoted to an inner radial position that causes the closest of the cutters to block the leading end of the object, and so that at another faster speed the shaft is centrifugally pivoted to an outer radial position which removes the particular cutter from the blocking relationship with the leading end of the object thereby allowing the object to be advanced past the remote cutter for a predetermined distance, and so that at another speed, which is less than the last mentioned speed, the shaft is centripetally pivoted inward to provide concurrent cutting of the object by the two disc cutters.Type: GrantFiled: June 14, 1982Date of Patent: March 13, 1984Assignee: International Business Machines CorporationInventors: James M. Ergler, Harold Kohn, Michael Smetana

Patent number: 4415113Abstract: Multiple pins are affixed in the holes of a ceramic substrate by simultaneously impacting the pins with a piston assembly which temporarily places the pins in a viscoelastic fluid state. Upon return of the pins and the resultant fluid flow to its undisturbed solid state, each pin is left with an extension that is in interlocking engaged relationship with the ceramic particles of the substrate in the region surrounding the particular holes in which the pins have been located.The piston assembly is driven by a pneumatic high pressure system which is adjustable to the number of pins being simultaneously impacted. Release of the piston assembly is delayed until the air pressure becomes stabilized prior to impact. A vacuum pressure system returns the piston to its originating position after impact whereupon the piston assembly is ready for the next impact cycle.Type: GrantFiled: January 7, 1981Date of Patent: November 15, 1983Assignee: International Business Machines CorporationInventors: David E. Houser, Harold Kohn, Gordon L. Williams
