摘要: Methods and apparatus for laser patterning leverage mask trench debris removal techniques to form etch singulation trenches. In some embodiments, the method includes forming a mask layer on the wafer, forming a pattern in the mask layer using a laser of a laser assembly where the pattern allows singulation of the wafer by deep etching and forms a trench in the mask layer with a laser beam which has a process point at a bottom of the trench, directing gas nozzles that flow a pressurized gas at the process point in the trench as the pattern is formed with a gas flow angle relative to the process point and evacuating debris from the trench using an area of negative pressure where the gas flow from gas nozzles and the area of negative pressure are in fluid contact and are confined within a cylindrical housing.

摘要: A laser cutting head uses a nozzle and gas flow to perform laser cutting or the like. The laser processing and the gas flow passes from an end of the housing. A sensor assembly affixed to the end of the housing has a first through which the laser processing passes and an orifice from which the gas flow passes. A conductive adapter affixes to the sensor assembly and has a passage through which the laser processing passes. The nozzle affixes in a receptacle in an end of the conductive adapter. A collar disposed about the adapter defining one or more gas flow passages therethrough. A cover is disposed between the sensor assembly and the collar and encloses a space communicating the gas flow from the orifice to the one or more flow passages of the collar.

摘要: An in-situ cladding method including providing a pipe with a target surface with a defected area. The method also includes lowering an in-situ cladding system into the pipe. The in-situ cladding system includes a dual head laser, with primary and secondary beams, and a wire feeding system. The method also includes lowering the wire feeding system into the pipe, feeding a cladding wire onto the target surface, melting the cladding wire onto the target surface with the primary beam, and blowing gas onto the cladding wire using an internal purging system. The method further includes forcing melting of the cladding wire in a first desired direction to form a first layer, forcing melting of the cladding wire in a second desired direction to form a second layer, switching off the primary beam and switching on the secondary beam, and welding the first and second layers together using the secondary beam.

摘要: The present disclosure provides a laser etching system for electrode layer patterning, which can perform electrode layer patterning on the conductive layer of a first surface of the substrate of a double-sided structure touch panel by means of employing a laser beam without damaging the conductive layer on the second surface of the substrate. The system comprises a laser emitter for generating and emitting laser beams, and a laser etching platform for supporting and fixing the touch panel substrate, with the first surface facing the laser beam and the second surface adhering to the laser etching platform. The laser etching system further comprises optical elements, which ensure that the ratio of the spot size of the laser beam irradiated on the second surface to that irradiated on the first surface is not less than 1.2.

摘要: A container can store a transmission inhibition liquid that inhibits transmission of a laser beam. A liquid storage unit has an internal space, and is connected to the container such that the transmission inhibition liquid stored in the container enters the internal space. A transmittance detection sensor detects transmittance of the internal space in the liquid storage unit.
