Contact Apparatus For Integrated Circuits

View page

US Patent:

60930306, Jul 25, 2000

Filed:

Jan 12, 1999

Appl. No.:

9/233502

Inventors:

Bernd Riechelmann - San Diego CA
Raymond Twigg - San Diego CA
Jason Hsang Wang - San Diego CA

International Classification:

H01K 909

US Classification:

439 72

Abstract:

An apparatus for electrically coupling a plurality of DUT terminals to corresponding terminals of a circuit. The apparatus includes a corresponding plurality of contact devices aligned both with the DUT terminals and the circuit terminals. Each contact device includes a fulcrum on which a contact lever is rockable over a range by pressing a corresponding DUT terminal against it. Each lever includes a first arm of "X" length on a DUT side of the fulcrum and a second arm of "Y" length on an opposite side of the fulcrum. A biasing spring, having travel, reacts against and through the second arm to resist rocking of the lever. Included is a way for electrically coupling the contact lever and its corresponding circuit terminal. The contact device operates according to the principle that contact lever travel, during rocking caused by a pressing upon it of a corresponding DUT terminal, is greater than responsive travel of the bias means according to a ratio of X/Y. The invention also includes a housing to contain the lever and bias means of each device in relation to each other.

Contactor With Multiple Redundant Connecting Paths

US Patent:

57919127, Aug 11, 1998

Filed:

Dec 1, 1995

Appl. No.:

8/565867

Inventors:

Bernd Riechelmann - San Diego CA
Raymond Twigg - San Diego CA

International Classification:

H01R 909

US Classification:

439 66

Abstract:

A contact array includes: (1) a plurality of uniform columns each for providing electrical continuity between things respectively in contact with opposite ends of the columns, each column means having a memory urging it to be straight, and (2) an elastomeric carrier, reinforced with a polymer, to which all the columns are affixed, for holding them parallel to each other, spaced apart, aligned along an axis normal to them, and preferably symmetrical with respect to the axis. The carrier also forces the columns to be uniformly arcuate along the axis. The opposite ends of the columns define respective opposite contact margins of the array. A housing defines a chamber for containing the array. Two opposite walls of the chamber define respective openings through which the contact margins protrude for accepting compressive contact forces that are applied during operation. The chamber further includes space to allow further, unobstructed, resilient arcuation of all the columns whenever the contact force is applied to the margins.

US Patent:

49648080, Oct 23, 1990

Filed:

Apr 24, 1989

Appl. No.:

7/342301

Inventors:

Bernd Riechelmann - San Diego CA

Assignee:

Sym-Tek Systems, Inc. - San Diego CA

International Classification:

G01R 3102

US Classification:

439264

Abstract:

A contact leaf bank for an electrical contactor preferably etched from a single uniform sheet of resiliently flexible, electrically conductive material comprises a ground sheet defining a plurality of uniformly-spaced, elongated, parallel slots in which are singularly disposed a plurality of resiliently flexible, elongated leaves each having and end portion adapted to be a contact finger, the tip of each contact finger preferably being rhodium-plated for hardness. A pair of spaced and opposing contact leaf banks are two elements of a contact assembly which futher comprises a base member in which a base end of each contact leaf bank is anchored, a device rail which in one form is a single track upon which an electrical device rides is centrally interposed between the contact leaf banks, the device rail being adapted to seat a device such that side leads of the device are aligned with the contact fingers and the spacing of the contact banks being such that the banks can be bent inboardly to make wiping contact between the device leads and the contact fingers, a pair of rockers one affixed to each bank at an end opposite the bank's anchored end and adapted to be reciprocatingly rocked or rotated toward and away from the device rail by an over-travel compensated actuating mechanism, the portion of each contact leaf bank between its respective rocket and the base member acting as a resilient hinge, and connector adaptors housed in the base member for providing electrical communication between the contact fingers and connectors also housed in the base member.

Contactor With Multiple Redundant Connecting Paths

US Patent:

59846909, Nov 16, 1999

Filed:

Nov 12, 1996

Appl. No.:

8/745705

Inventors:

Bernd Riechelmann - San Diego CA
Raymond Twigg - San Diego CA

International Classification:

H01R 909

US Classification:

439 66

Abstract:

A contact array includes a plurality of uniform columns each for providing electrical continuity between things respectively in contact with opposite ends of the columns, each column means having a memory urging it to be straight. In a first embodiment the columns are all affixed to plurality of polymeric carrier films for holding them parallel to each other, spaced apart, aligned along an axis normal to them, and preferably symmetrical with respect to the axis. Each column can include a plurality of aligned, elongated contact leaves, each leaf having a memory urging it to be straight. In a second embodiment the columns each comprise a set, preferably ten, of loosely aligned contact leaves held in place by being disposed in slots defined by a housing. The housing forces the columns to be uniformly arcuate along the axis. The opposite ends of the columns define respective opposite contact margins of the array.
