Publication number: 20220193614Abstract: Devices, systems, and methods for continually degassing/venting a feedstream within a filtration system. The filtration system may include a filter device utilizing hollow fiber filters to filter the feedstream. Additional venting hollow fiber filters vent gas from the filtration system to outside the filtration system. The venting hollow fiber filters may have ends which expose the interior lumens thereof to outside the filter unit to vent gases which pass through the walls of the hollow fiber filters. Degassed permeate thus flows through the filtering hollow fiber filters.Type: ApplicationFiled: December 22, 2021Publication date: June 23, 2022Applicant: Repligen CorporationInventors: Bao Le, Philip Yuen

Patent number: 6617510Abstract: A metallic or an electrical trace having a terminus and a stress relief bend formed in the trace adjacent the terminus. The electrical trace may have a portion carried by a flexible substrate to form a flexible circuit. The stress relief bend may be free floating and extend from the flexible substrate or may be encapsulated by the flexible substrate. The electrical circuit and the flexible circuit each have a generally planar portion extending in the X and Y axis, with the stress relief bend projecting into the Z axis. This allows electrical traces to be spaced with a very narrow pitch because the stress relief bend does not consume any valuable real estate on the flexible circuit or the substrate to which the electrical trace is applied.Type: GrantFiled: September 18, 2001Date of Patent: September 9, 2003Assignee: Delphi Technologies, Inc.Inventors: Chris M.

Patent number: 6449840Abstract: A method for providing C4-type bumps which are higher than conventional C4 bumps. A dielectric substrate is copper cladded on both sides. At each prospective bump location, a via is laser ablated through the cladded substrate. A copper core is deposited within the vias to thereby connect the two claddings. A photoresist is applied to both claddings, a photomask having a predetermined exposure pattern is placed over the claddings, the photoresist is exposed to ultraviolet (UV) light to thereby polymerize in the exposed areas thereof, and the resulting photoresist image is developed by use of a developer solution to wash away of the unpolymerized areas of the photoresist. Now, the photoresist image provides a retainer wall spaced from, and circumferentially around, the vias. Next, a lead-tin solder alloy is electroplated, such as by a lead-tin fluoroborate bath, at the vias into the volumes defined by the retainer wall at each end of the vias.Type: GrantFiled: September 29, 1998Date of Patent: September 17, 2002Assignee: Delphi Technologies, Inc.Inventors: Bao Le, Chris M.

Patent number: 6085414Abstract: A process using a shim stock or foil to make flexible circuits having raised pressure contact features protruding outwardly from two surfaces. A first set of raised electrical pressure contact features are made by placing a shim stock or foil of stainless-steel on a piece of soft metal or other suitable substrate and forcing a tool into the foil to form dimples in one face. Thereafter, the foil is turned over and the process repeated on the other face of the foil. The resultant foil includes a first face having a first dimple and a first bump extending outwardly from the first face. A flash coating is formed on the foil and electrical traces are deposited on the first face of the foil including into the first dimple and over the first bump. A dielectric substrate is selectively deposited over the electrical traces and the complete subassembly is removed from the foil. A flash coating is etched away and optionally a second dielectric substrate is selectively deposited over the electrical traces.Type: GrantFiled: July 30, 1998Date of Patent: July 11, 2000Assignee: Packard Hughes Interconnect CompanyInventors: David Bryan Swarbrick, Bao Le, Oswaldo Ernesto Caballero

Patent number: 5708557Abstract: The invention includes a puncture-resistant electrostatic chuck with a flat surface and a method of making the same. The electrostatic chuck includes a conductive layer such as copper foil that is laminated to a first insulation layer such as a polyimide. A puncture-resistant layer is placed over the conductive layer and includes random or woven fibers held together by a resin. The puncture-resistant layer has an uneven topography on a top surface due to the fibers contained therein. A second insulation layer overlies the puncture-resistant layer and has a top surface which is substantially flat. The flat top surface of the second insulation layer is made by laminating layers together with a mandrel which is polished and free of irregularities such as pits, dents and high spots. Preferably the mandrel has a uniform thickness over its entire surface.Type: GrantFiled: August 22, 1996Date of Patent: January 13, 1998Assignee: Packard Hughes Interconnect CompanyInventors: Haim Feigenbaum, Bao Le, Randy Lee Thomas, Dong Vo
