Title: Innovations by Joel T. Harrison
Introduction
Joel T. Harrison is an accomplished inventor based in Henrico, VA (US). He has made significant contributions to the field of technology, holding a total of 2 patents. His work primarily focuses on advanced fabrication methods and microelectronics.
Latest Patents
One of his latest patents is titled "Laser fabrication of lead selenide thin film." This innovative method involves a laser sintering deposition technique for applying lead selenide onto a substrate. The process includes wet-milling a lead selenide ingot mixed with methanol into a colloidal slurry containing nanocrystals. The slurry is then separated into nanocrystal particles and methanol, followed by the deposition of the nanocrystal particles onto a substrate. Coherent infrared light is emitted onto the particles to fuse them into a lead selenide crystalline film. The film can later be exposed to oxygen to form a lead selenite layer, and subsequently to iodine gas to produce a lead iodide layer.
Another notable patent is "Wiresaw removal of microelectronics from printed circuit board." This assembly is designed for mechanically severing ball grid array (BGA) attachment solder between an electronics chip and a printed circuit board. The assembly features a bridge fixture, a tungsten wire, and removable spacers. The bridge fixture extends over the chip, with a pair of guide bars flanking it. Each guide bar has a wire engagement surface, and the tungsten wire is positioned across the chip between the guide bars. The removable spacers align the wire to engage the solder effectively.
