Abstract:
Termination assemblies for terminating high-frequency data signal transmission lines include housings with one or more cavities that receive ends of the transmission line therein. The transmission line typically includes a dielectric body and a plurality of conductive elements disposed thereon, with the plurality of conductive elements being arranged in pairs for differential signal transmission. The termination assemblies, in one embodiment include hollow end caps that are formed from a dielectric and which have one or more conductive contacts or plated surfaces disposed on or within the cavity so that they will frictionally mate with the conductive traces on the transmission line. In another embodiment, a connector housing is provided with a center slot and a plurality of dual loop contacts to provide redundant circuit paths and low inductance to the termination assembly. A coupling element may be utilized in the slot to achieve a desired level of coupling between the termination contacts.

Abstract of the Disclosure FileNameFileName-33-Integrated circuit packages including interconnection posts with multiple metal terminals are disclosed. An exemplary package includes a molded plastic body with integral plastic posts extending from the body. Each post is coated with a plurality of electrically separate metal terminals. The metal terminals extend from a surface of the body, along a sidewall of a respective post, to an end of the post. An integrated circuit is mounted on the body. Conductive paths, which may include vias through the body, electrically couple different bond pads of the integrated circuit to the metal terminals of the posts. In some embodiments, posts on opposing sides of the plastic body enable stacking, and electrical coupling, of two or more packages. The metal terminals of posts of the lower package may be engaged with the metal terminals of corresponding posts on a mounting substrate.

Abstract:
An improved electronic component or integrated circuit (IC) package characterized by an extraordinary small size for the number of input-output (I/O) leads which are available and capable of use on surface mounted, Flat Pack, hybrid, or through hole (DIP) printed circuit boards. The package has one or more cylindrical or shaped forms at the base, with a flange to provide a stop in order to limit the insertion travel in those circuit boards having through holes, and a top body which is used to house the electronic device. The forms, which protrude down from the upper body (housing), have one or more conductive lead segments, either pins or printed circuit types, running longitudinally and continuing through the housing to the upper body.Each lead segment is connected directly to the electronic device or attached via an additonal lead to a pad on the electronic device, mounted on the upper body. A cover to seal the device is provided. Grooves in the body or on the cover aid in handling the device, either manually or by automatic machinery, are provided. These grooves also provide gripping areas for top hat heat sinks.
