Latest Patents
Among his latest innovations is the high-frequency BGA connector, which is designed for surface mounting with a solder reflow process. This connector features closely spaced solder masses on the mounting ends of reference contacts, which may fuse to enhance shielding. The design allows for the mounting ends of signal and reference contacts to be positioned in rows, ensuring that the solder masses of the reference contacts shield those attached to signal contacts in adjacent rows. Additionally, the connector's design includes pockets in the housing surface for the signal contacts, with solder balls that may be fused to an edge of the signal contact to set a desired impedance.
Another significant patent is for differential pair signal contacts with skew correction. This electrical connector is configured for differential pairs with low in-pair skew. It comprises lead frame assemblies, including insert molded lead frame assemblies, where adjacent conductors are arranged to reduce skew by distributing skew correction throughout the transmission path. The design incorporates elongated air gaps in the housing, exposing the longer conductor of each pair, which helps to cancel or prevent in-pair skew.
