07/03/14 - 20140182891 - Geometrics for improving performance of connector footprints
In accordance with the various embodiments disclosed herein, an improved electrical connector footprint, such as on printed circuit boards (PCB), is described. For example, antipads can have a variety of sizes and pairs of differential signal traces can define centerlines that are spaced apart from each other....
Inventors: Madhumitha Rengarajan, Jan De Geest, Stephen B. Smith, Stefaan Hendrik Jozef Sercu

02/27/14 - 20140057493 - High speed electrical connector
An electrical connector assembly includes a first electrical connector and a second electrical connector. Each electrical connector can include an electrical ground shield that at least partially surrounds respective differential signal pairs....
Inventors: Jan De Geest, Stefaan Hendrik Jozef Sercu, Johannes Maria Blasius Van Woensel

12/26/13 - 20130344743 - Contact pin, header connector and connector assembly
The invention relates to a contact pin having longitudinal surfaces bulged to define opposite contact lines extending in longitudinal direction of the contact pin, wherein in cross section of the contact pin the plane through the two opposite contact lines is offset from the cross sectional centre of the contact...
Inventors: Jeroen De Bruijn, Gert Droesbeke, Winnie Heyvaert, Ludwig Lange, Stefaan Hendrik Jozef Sercu

08/08/13 - 20130199834 - Structured circuit board and method
A circuit board (1) is provided comprising a plurality of insulating layers, at least one ground layer and at least one layer comprising signal traces. The circuit board comprises at least a first conductive via (17) and a second conductive via (17). The first conductive via and the second conductive...
Inventors: Jan De Geest, Stefaan Hendrik Jozef Sercu (Fci)

07/18/13 - 20130183869 - Shieldless, high-speed, low-cross-talk electrical connector
An electrical connector may include a first connector with electrically-conductive contacts. The contacts may have blade-shaped mating ends, and may be arranged in a centerline. The electrical connector may include a second connector with electrically-conductive receptacle contacts, which may also be arranged in a centerline. The connectors may be mated...
Inventors: Steven E. Minich, Douglas M. Johnescu, Stefaan Hendrik Jozef Sercu, Jonathan E. Buck

04/05/12 - 20120083155 - Shieldless, high-speed, low-cross-talk electrical connector
An electrical connector may include a first connector with electrically-conductive contacts. The contacts may have blade-shaped mating ends, and may be arranged in a centerline. The electrical connector may include a second connector with electrically-conductive receptacle contacts, which may also be arranged in a centerline. The connectors may be mated...
Inventors: Steven E. Minich, Douglas M. Johnescu, Stefaan Hendrik Jozef Sercu, Jonathan E. Buck

03/08/12 - 20120058684 - Low-cross-talk electrical connector
An electrical connector includes a plurality of leadframe assembly, each having a leadframe housing and a plurality of contacts carried by the leadframe housing. At least a pair of adjacent leadframe assemblies includes respective first and second conductive member portions that are seated in the leadframe housing at a desired...
Inventors: Jan De Geest, Stefaan Hendrik Jozef Sercu, Jonathan E. Buck, Douglas M. Johnescu, Stuart C. Stoner, Stephen B. Smith

12/29/11 - 20110318945 - Electrical connector with ground plates
An electrical connector and leadframe assemblies for use therein are provided. Each leadframe assembly can be constructed with at least one electric contact having a ground plate. A first type of leadframe assembly includes an uppermost electrical contact defining a ground plate. A second type of leadframe assembly includes a...
Inventors: Jan De Geest, Stefaan Hendrik Jozef Sercu, Stephen B. Smith, Douglas M. Johnescu, Jonathan E. Buck

10/20/11 - 20110256763 - Mitigation of crosstalk resonances in interconnects
In an electrical connector, a non-grounded, electrically conductive material (such as copper foil or other sheet of metal) may be located adjacent to at least one differential signal pair. An example includes a ring of material that circumscribes a leadframe assembly. Ring-shaped structures placed around, but not in contact with,...
Inventors: Jan De Geest, Stefaan Hendrik Jozef Sercu, Jonathan E. Buck, Douglas M. Johnescu, Stuart C. Stoner, Stephen B. Smith

11/18/10 - 20100291806 - Shieldless, high-speed, low-cross-talk electrical connector
