61007072, Aug 8, 2000

Filed:

Sep 25, 1998

Appl. No.:

9/160801

Inventors:

Josef Baumann - Phoenix AZ
Jakob Herrmann - Chandler AZ

Assignee:

Electro Scientific Industries, Inc. - Portland OR

International Classification:

G01R 1073
G01R 3102

US Classification:

324761

Abstract:

To facilitate the testing of small electronic components, an improved test probe and transport wheel assembly are disclosed. The basic form of the probe features a fixed support body onto which a movable base is secured by at least one resilient structure. Secured to the movable base are a number of leads that may be moved through complementary tunnels in a fixed guide block toward the side-located terminals of an electronic component to be tested. The transport wheel assembly includes a wheel that has a number of peripherally-located compartments for receiving the electronic components. Each of the compartments includes a metal base. Also disclosed is a metal roller that is designed to press on an end of a component during testing. The metal base of each compartment and the metal roller facilitate electrical connection to the component's end-located terminals by side-located leads from the test probe.

Abstract:

To facilitate the testing of small electronic components, an improved test probe is disclosed. The basic form of the probe comprises a support body made of at least one strip of circuit board material. A pill-shaped conductive contact is secured to and extends outwardly from a front end of the support body. A conductive layer of the circuit board strip connects the contact to a lead that extends outwardly from a rear end of the support body. A middle part of the support body features a series of thru-cuts that enable the support body to resiliently flex and act like a spring.
