  • Circuit for flash lamp
    Patent number: 9326365
    Abstract: A circuit for a gas discharge system includes a pulse forming circuit, a discharge lamp, a circuit for recovering energy from the discharge lamp when a trigger to the lamp is turned off, a high voltage switch between the lamp and ground, and a two-part dissipating circuit across the switch. The system can provide a flat response with highly controllable pulse width.

  • SYSTEMS AND METHODS FOR CONTINUOUS FLASH LAMP SINTERING
    Publication number: 20150181714
    Abstract: A flash lamp system for providing at least one continuous flash lamp pulse including at least two stages for sintering. The pulse can include a first portion for a first time period to reach a first peak energy level, and a second portion for a second time period to reach a second peak energy level. The one or more pulses have sufficient energy to sinter the layer of particles such that the printed electronic circuit is conductive.

  • FLASH LAMPS IN A CONTINUOUS MOTION PROCESS
    Publication number: 20140042342
    Abstract: A system controls a group of flash lamps to provide energy to a work product in a continuous motion processes. The system can identify optimal relationships among various parameters, including the speed of the target material, the physical spacing of the flash lamps, the pulse frequency, and the flash sequence of the lamps. The systems can respond to changes in conditions to automatically adjust parameters. These systems can be applied to design practical sintering, annealing, and/or curing systems.
