Patent number: 9609738Abstract: A formed graphite sheet is shaped and sized as a protective shield positioned over an electronic component coupled to a PCB. The formed graphite sheet is used to protect a body of the electronic component from heat applied during the assembly of the electronic component to the PCB, such as the heating steps used in SMT and through-hole technology. The formed graphite sheet is shaped to selective direct impinging heat. The heat can be directly away from the entire electronic component. Alternatively, the heat can be selectively directed away from some portions of the electronic component and toward other portions of the electronic component.Type: GrantFiled: December 4, 2014Date of Patent: March 28, 2017Assignee: Flextronics AP, LLCInventors: Dennis Willie, Richard Loi, David Geiger, Anwar Mohammed, Murad Kurwa, Hector Rene Marin Hernandez

Patent number: 9609744Abstract: Printed circuit boards (PCBs) can be designed to have dynamic warp characteristics complimentary to those of an attached component. A PCB and an attached component can be designed to dynamically warp, during a thermal excursion, in the same direction and with approximately the same magnitude of warp. Warp characteristics of the PCB and the attached component can be determined by the vertical thickness of conductor and dielectric layers, by the wiring density and number of conductor layers. Warp characteristics can also be at least partially determined by the arrangement/ordering of conductor and dielectric layers, by dimensions of a sash structure surrounding a component outline and by dimensions of a prepreg layer applied to an existing design. Such a prepreg layer can cover a portion or an entirety of one of the PCBs planar surfaces.Type: GrantFiled: March 24, 2015Date of Patent: March 28, 2017Assignee: International Business Machines CorporationInventors: Mark K. Hoffmeyer, Amanda E. Mikhail, Arvind K. Sinha
