Abstract: A connector for surface mounting with a solder reflow process with closely-spaced solder masses on mounting ends of reference contacts. The solder masses on the reference contacts may fuse for enhanced shielding. The mounting ends of signal and reference contacts may be positioned in rows, configured such that the solder masses of the reference contacts may shield solder masses attached to signal contacts in adjacent rows. The mounting ends of the signal contacts may be disposed in pockets in a surface of the connector housing. In some embodiments, solder balls may be fused to an edge of the signal contact, with the length of the edge extending beyond locations at which the solder ball is fused to. The edge may extend through a wall of the pocket, so as to set a desired impedance in the mounting region of the connector.

Abstract: An electrical connector configured for differential pairs with low in-pair skew. The connector may comprise lead frame assemblies, such as insert molded lead frame assemblies, with adjacent conductors configured for reduced skew by distributing skew correction throughout the transmission path through the lead frame assembly. Elongated air gaps are formed in a side of the housing, exposing the longer conductor of each pair. The elongated air gap may span the entire length of the arc of a longer conductor of each pair. The width of this air gap may be different for different pairs in the lead frame assembly and may be selected to cancel or prevent in-pair skew from arising. The width for each pair may be selected to tune the effective dielectric constant of the longer conductor such that its electrical length matches that of the shorter conductor.

Abstract: A card edge connector with an improved manner of creating a preload force on conductive elements held by a housing. The housing may include a member and an opening at a mating end. Each conductive element may have a contact portion curving inwardly relative to the opening and a tip extending from the contact portion towards the mating end. Each contact portion may form an electrical connection with an edge pad of a card to be inserted into the opening. The conductive elements may be configured to have a rest state in order to create a proper force to be exerted on the edge pads. The member may preload the conductive elements by contacting the conductive elements from a location farther from the mating end than the contact portion, which may avoid damage upon insertion of a card into the connector without the need for long tips of the conductive elements. As a result, the connector may operate at high frequencies.
