Publication number: 20180358770Abstract: Disclosed is an electrical connector having a substrate and movable electrical contacts which are mounted to the substrate and extend a distance D from the substrate. A layer of compressible material (such as a foam or elastomeric material) is positioned on the substrate adjacent at least some of the electrical contacts and ideally has an uncompressed thickness slightly greater than the distance D to provide for protection of the electrical contacts. When a mating electrical device such as an electrical connector or other circuit member is mated to the electrical connector with its electrical contacts and its layer of compressible material, the layer of compressible material is compressed to a thickness less than the distance D, allowing the contacts to make a suitable electrical interconnection to the mating electrical device.Type: ApplicationFiled: June 10, 2017Publication date: December 13, 2018Applicant: Neoconix, Inc.Inventors: David Noel Light, Hung-Ming (NMI) Wang, David Rodney Baker, Peter Tho Nguyen, Dexter Shih-Wei Pao

Publication number: 20140154893Abstract: The present invention is an electrical connector in which a substrate (such as a printed circuit board or PCB) includes a plurality of apertures (or vias) and some of those apertures are filled with two materials to improve the characteristics of the electrical interconnection. The preferred process of crating the filled vias includes the steps of plating the vias with an electrically-conductive material to create an electrically-conductive path between portions of the substrate and components associated with the substrate and partially filling the apertures, then filling at least a portion of the apertures or vias with a second or different filling material to seal at least apart of the electrically conductive path through the plating. The second filling material may be chosen to provide thermal compensation for the connection.Type: ApplicationFiled: February 4, 2014Publication date: June 5, 2014Applicant: Neoconix, Inc.Inventors: David Noel Light, Dinesh Sundararajan Kalakkad, Peter Tho Nguyen

Patent number: 6178630Abstract: The present invention provides a new device and technique for enhancing the electrical properties of the thick metal backer/adhesive bond/ground plane interface. The enhanced electrical properties are obtained by micro-roughening a connection surface of the thick metal backer prior to forming the thick metal backer/adhesive bond/ground plane interface.Type: GrantFiled: January 12, 1999Date of Patent: January 30, 2001Assignee: International Business Machines CorporationInventors: Lisa Jeanine Jimarez, David Noel Light, Andrew Michael Seman, David Brian Stone

Patent number: 6066808Abstract: Pads which are attached to a high density printed circuit board (PCB) having a plurality of through-holes opening on the top surface. A plurality of pads are formed on a carrier sheet so that each of the pads have a copper layer proximate to the carrier sheet and a joining metal layer formed on top of said copper layer. The plurality of pads are positioned on the carrier sheet so that they are aligned with the through-hole pattern on the top surface of the PCB, the pads bing laminated to the through-holes on the top surface using the joining metal, and the carrier sheet being separated from the plurality of pads that are joined to the through-holes so that the copper layer is exposed. The pads may possess a variety of shapes such as disk-shaped, elongated, or rectangular, and can cover one or multiple through-holes. An electrical component may be soldered to the pad.Type: GrantFiled: April 10, 1998Date of Patent: May 23, 2000Assignee: International Business Machines, Corp.Inventors: John Steven Kresge, David Noel Light

Patent number: 5736679Abstract: A novel through-hole interconnect for connecting a power plane conductor to a through-hole includes a central pad connected to the through-hole and a deformable hinge that connects the central pad with the power plane conductor in a multilayer circuit board. The central pad and hinge are defined by a non-continuous area removed from the plane conductor. Preferably this area has a C-shape. During the compression process to join the core assemblies, deformation of the hinge advantageously absorbs the shear forces and allows the power plane beyond the hinge to remain substantially planar. The resulting multilayer laminated circuit board includes a plurality of cores laminated together in a stacked configuration and a plurality of plated through-holes defined in said multilayer laminated circuit board each of which is connected to a plane conductor by a hinge deformed so that the interconnect area is aligned outside of a plane defined by the plane conductor.Type: GrantFiled: December 26, 1995Date of Patent: April 7, 1998Assignee: International Business Machines CorporationInventors: John Steven Kresge, David Noel Light, James Robert Wilcox
