  • Publication number: 20200065451
    Abstract: An electromigration (EM) sign-off methodology that analyzes an integrated circuit design layout to identify heat sensitive structures, self-heating effects, heat generating structures, and heat dissipating structures. The EM sign-off methodology includes adjustments of an evaluation temperature for a heat sensitive structure by calculating the effects of self-heating within the temperature sensitive structure as well as additional heating and/or cooling as a function of thermal coupling to surrounding heat generating structures and/or heat sink elements located within a defined thermal coupling range.

  • Publication number: 20010003939
    Abstract: An automatic carton slitting machines includes a transmission means for moving cartons, a sensing and positioning means for detecting and positioning the cartons at locations desired, a slitting means for slitting the carton and a control unit for coordinate and control the operations of all other means. The cutter means includes two spaced cutter sets each has a motor driven rotating saw cutter with adjustable slitting angle. One of the cutter sets is movable by a cutter set moving means for changing spacing distance between the cutter sets to process carton of different width. The cutter means also has a frame lifting means to adjust cutter sets height for processing cartons of different height. Through coordinating the transmission means, cutter set moving means and frame lifting means may coordinate their motion so that the cutter sets may move in three dimensions against the carton for automatically cleaving cartons of different size.
