Patent number: 8215535Abstract: A method and a system for jetting droplets of viscous medium, such as solder paste, onto a substrate, such as an electronic circuit board. The volume of the droplets are adjusted by regulating the amount of viscous medium that is fed into a jetting nozzle for subsequent jetting of the viscous medium droplets therefrom. The exit velocity of the jetted droplets is adjusted or maintained substantially constant by regulating the velocity with which the viscous medium is impacted. Furthermore, the rate at which viscous medium is fed, for instance by a feed screw, into the nozzle is adjusted in order to regulate the feeding time required for feeding the viscous medium into the jetting nozzle, for instance in order to maintain a constant feeding time.Type: GrantFiled: July 23, 2010Date of Patent: July 10, 2012Assignee: Mydata Automation ABInventors: William Holm, Kenth Nilsson, Johan Berg, Johan Kronstedt, Häkan Sandell

Patent number: 7401744Abstract: A jetting device and a method of jetting droplets of viscous medium onto a substrate. The jetting device includes a jetting outlet through which the droplets are jetted. The jetting device further includes a wall located at the jetting outlet, downstream of the jetting outlet seen in the jetting direction. The wall is provided with an orifice through which jetted droplets are permitted to pass through. A gaseous flow is provided within the space past the jetting outlet such that an adverse effect on the performance of the jetting device is prevented, the adverse effect resulting from the accumulation of viscous medium residue at the jetting outlet.Type: GrantFiled: April 25, 2002Date of Patent: July 22, 2008Assignee: Mydata Automation ABInventors: William Holm, Kenth Nilsson, Johan Kronstedt, Mårten Lundberg, Johan Berg, Mikael Bergman, Nicholas Glazer

Patent number: 6450416Abstract: The present invention refers to a method and a device for jetting droplets of a viscous medium onto an electronic circuit board. According to the invention, the viscous medium is applied from a viscous medium supply container to an eject chamber through a tubular passage using a rotatable feed screw arranged within the tubular passage. The viscous medium is then jetted from the eject chamber through an eject nozzle by the rapid decreasing of the volume of the chamber.Type: GrantFiled: January 31, 2001Date of Patent: September 17, 2002Assignee: Mydata Automation ABInventors: Johan Berg, William Holm, Johan Kronstedt, Kenth Nilsson

Patent number: 4887309Abstract: The present invention relates to optical repeaters in a two-way optical line link, e.g. one included in a teletransmission system. The optical repeaters are implemented such as to provide a system which, inter alia in fault localizing, utilizes the line link transmission capacity optimally by completely optical through-connection of signals on the optical fibre cables. In fault localizing, one repeater at a time is checked, by an end terminal in the link transmitting a test signal including an address for selecting a repeater for testing and a test pattern. An optical amplifier amplifies the test signal in every repeater through which the signal passes, and when it reaches the repeater indicated by the address, a control circuit controls an optical switch such that the test signal is switched (loop connected) and is returned to the transmitting terminal where fault analysis takes place.Type: GrantFiled: June 13, 1988Date of Patent: December 12, 1989Assignee: Telefonaktiebolaget L M EricssonInventors: Ove B.
