Publication number: 20120112780Abstract: A test socket for an integrated circuit device includes a base for receiving the circuit device and a frame movable linearly toward and away from the base. Springs bias the frame away from the base. Device holders are movable substantially linearly on the frame between a closed position where the device holders are in proximity to one another and an open position where the device holders are remote from one another. Cams move the device holders between the open and closed positions in response to movement of the frame toward and away from the base.Type: ApplicationFiled: November 8, 2011Publication date: May 10, 2012Applicant: ARIES ELECTRONICS, INC.Inventor: Brian Groeger

Publication number: 20050257953Abstract: A method of creating domed shaped contacts on a printed circuit board includes etching a central opening in each copper pad, and then screening a mound of silver epoxy into the opening. The silver epoxy above the pad slumps to form a domed bump. The silver epoxy is then cured and is coated, in turn, by a layer of electroless nickel and gold. The resulting gold plated contacts are of monolithic structure and function to facilitate connection to a mezzanine board.Type: ApplicationFiled: May 11, 2005Publication date: November 24, 2005Applicant: Aries Electronics, Inc.Inventors: James Walter, William Sinclair

Patent number: 6937045Abstract: A test probe consists of an elongated screw machine contact biased by a helical spring and mounted in a through hole of a non-conductive substrate. One end of the contact includes a crown for engaging a solder ball lead of an IC package, and the contact includes an intermediate collar which maintains the contact within the through hole. The helical spring is disposed about the contact, with one end thereof engaging the lower end of the collar. The other end of the helical spring has contiguous coils and is of a reduced diameter so as to extend beyond the lower end of the non-conductive substrate to make electrical contact with a printed circuit board. When the test probe is compressed between the IC package and the printed circuit board, the inherent twisting of the helical spring causes the contact to tilt and make electrical contact with the contiguous coils, thereby establishing a direct electrical path between the IC package and the printed circuit board, with minimum resistance and minimum inductance.Type: GrantFiled: June 17, 2004Date of Patent: August 30, 2005Assignee: Aries Electronics, Inc.Inventor: William Y.

Patent number: 6341962Abstract: A connector assembly is provided for solderlessly connecting an integrated circuit package to a printed circuit board. In the first embodiment of the invention, a plurality of generally cylindrical resilient electrical contacts are disposed in through holes formed in a non-conductive substrate. The contacts are formed from a single conductor that is coiled in a helical fashion to form a contact which resembles a spring. Each spring-like contact is formed to begin with an annular rim defining a contact point. The conductor is then coiled in such a manner to form diametrically equal rings which are spaced equidistant apart. The spring-like contact is then concluded with a similar annular rim as to the beginning contact point. An intermediate portion equidistant from beginning and concluding rims is formed so that a small portion of coiled turns have a diameter which is larger than the other diameters defined by the annular rim.Type: GrantFiled: October 25, 2000Date of Patent: January 29, 2002Assignee: Aries Electronics, Inc.Inventor: William Y.
