Patent number: 7097806Abstract: A mist of liquid coolant is introduced into the path of atomized, molten, solder droplets. The mist and other conditions within the chamber are engineered to enable the liquid coolant droplets in the mist to contract the surfaces of molten solder droplets and be flash vaporized upon contact, thereby rapidly extracting heat from the molten solder droplets and accelerating cooling and solidification to produce an enhanced solder ball as a product of this process.Type: GrantFiled: August 31, 2001Date of Patent: August 29, 2006Assignee: Fry's Metals, Inc.Inventor: Gerard R.

Patent number: 7093746Abstract: A stencil used for printing solder paste on a contact pad of a printed wiring board has interior surfaces that define one or more apertures through the stencil. Those interior surfaces are coated with a material, such as parylene, having a lower surface tension than the interior surfaces absent the coating. The stencil can also have one or more reverse-tapered apertures passing there through, wherein the apertures have a variable cross-section that is larger at the fill side of the stencil (i.e., where solder paste enters the apertures) than at the board side of the stencil (i.e., where the stencil contacts the contact pad of the printed wiring board). Solder paste can be printed through the aperture(s) of the stencil onto contact pads on a printed wiring board.Type: GrantFiled: July 26, 2004Date of Patent: August 22, 2006Assignee: Fry's Metals, Inc.Inventors: Ian McPhee Fleck, Ron Tripp, Prashant Chouta, Scott Craig

Patent number: 6938227Abstract: Customer data relating to the location and character of features (e.g., conductive pads to which electronic parts are soldered on a printed circuit board) are stored in a digital form (e.g., as “Gerber data”). A library of footprints that characterize the features is created from this data. A footprint filter and a modification parameter are then applied to the footprint library to select footprints for modification and to make a desired change to the selected footprints. In a printed circuit board embodiment, apertures in a stencil designed for printing solder on the printed circuit board are then cut in accordance with the footprints. Data representing all the apertures to be cut in the stencil can be moved or scaled to compensate for variations in the printed circuit board manufacturing and stencil manufacturing processes. The above-described method can be carried out via instructions stored as software code on a computer-readable medium.Type: GrantFiled: August 8, 2003Date of Patent: August 30, 2005Assignee: Fry's Metals, Inc.Inventors: Michael Murphy, Eric Schmidt, Aly Diaz

Publication number: 20050184129Abstract: A solder preform for use to attach an electronic component to a substrate. The preform is for placement by a pick-and-place machine using a vacuum nozzle which picks the preform from a preform holder. Each of the sides of the preform configured to function as a vacuum side pick up surface has an enlarged planar surface area. Methods for forming such solder preforms are also disclosed.Type: ApplicationFiled: December 15, 2004Publication date: August 25, 2005Applicant: Fry's Metals, Inc.Inventors: Paul Godijn, Wim Veldhuizen, Patrick Lusse, Mitchell Holtzer, Rob Ekeren, Martin Haan

Patent number: 6863447Abstract: Photon-conducting receiving and transmitting media (e.g., optical fibers) are aligned by coupling the receiving medium with a thermokinetic structure, which can include a shape memory alloy. A photon beam is directed from the transmitting medium onto the thermokinetic structure, thereby locally heating the thermokinetic structure. The heated portion of the thermokinetic structure contracts to displace other portions of the structure and the receiving medium, which is coupled therewith, toward the photon beam so as to align the media.Type: GrantFiled: November 22, 2002Date of Patent: March 8, 2005Assignee: Fry's Metals, Inc.Inventor: Kenneth B.
