Patent number: 8298002Abstract: A pair manager for use in securing a twin-axial cable to a printed circuit board is described. The pair manager comprises a generally block-shaped portion containing a pair of channels. The channels extend from the front face to the rear face of the block-shaped portion. An integral flange and a pair of integral fingers extend perpendicularly from the front face of the block-shaped portion. The flange extends generally from the center of the front face and the fingers extend from opposite edges of the front face. The fingers and flange function as a partial shield cavity around each pair of conductors. This design helps to maintain better impedance matching when connecting twin-axial cables to a printed circuit board.Type: GrantFiled: April 2, 2012Date of Patent: October 30, 2012Assignee: Panduit Corp.Inventors: Satish I.

Patent number: 7145085Abstract: The invention provides a subassembly to facilitate co-planar vertical surface mounting of subassembly boards. By “vertically mounting” is meant that a subassembly circuit board with a major surface is mounted perpendicular to the major surface of a circuit motherboard. In accordance with the invention, a subassembly for co-planar vertical surface mounting comprises a subassembly board coupled between a pair of base headers. Advantageously one base header comprises a plurality of mounting lugs secured to a transverse element in a co-planar configuration. The other base header conveniently comprises a plurality of connector pins secured to an elongated header element in co-planar configuration. The two headers interlock with the board to provide connection and co-planar support. Edge metallization of the subassembly board can provide enhanced thermal or electrical connection to the underlying portions of one or more lugs.Type: GrantFiled: October 21, 2004Date of Patent: December 5, 2006Assignee: Power One, Inc.Inventors: David Keating, Antoin Russell, Thomas H. Templeton, Jr., Mysore Purushotham Divakar

Patent number: 6946744Abstract: A mounting structure for a semiconductor die that reduces die attach strain within the die attach material without sacrificing the electrical and thermal characteristics of the package. In one embodiment, the mounting structure comprises a die attach metallization layer, a solder mask, and a layer of die attach material. The solder mask forms a solder pattern over the top surface of the die attach metallization layer. The solder pattern covers a portion of the die attach metallization layer to create multiple exposed areas of the die attach metallization layer. Each exposed area is separated by the solder mask and is located under the semiconductor die when the semiconductor die is secured to the mounting structure. A layer of die attach material covers the solder pattern and fills in each one of the exposed areas to form a semiconductor die mounting surface. In another embodiment, the die attach metallization layer is divided into multiple, spaced-apart die attach pads that are electrically coupled together.Type: GrantFiled: April 24, 2003Date of Patent: September 20, 2005Assignee: Power-One LimitedInventors: John Alan Maxwell, Mysore Purushotham Divakar, Thomas Henry Templeton, Jr.
