    摘要： A system and a method detect solder paste printing. The system includes a detecting device for detecting solder paste when a scraping blade pushes the solder paste to spread over a template to obtain information associated with the rolling speed of the solder paste, and a state-indicating device for generating a printing-state indication based on the information associated with the rolling speed of the solder paste. The method includes detecting the solder paste during rolling to obtain the information associated with the rolling speed of the solder paste, and generating a printing-state indication based on said information associated with the rolling speed of the solder paste. By detecting the solder paste during rolling to obtain the printing state, it is possible to monitor the printing state in real time, discover an abnormal condition in time, and reduce costs to the maximum extent.

    摘要： A light emitting control device for a light emitting diode print head includes a control unit, a pulse-mask unit, a strobe unit and a data output unit. The pulse-mask unit outputs n clock signals in sequence to a light emitting diode print head. The strobe unit outputs a strobe signal to the light emitting diode print head, so as to switch on the light emitting diode print head. The data output unit outputs a print data signal to the light emitting diode print head. When the pulse-mask unit outputs a k-th clock signal of the n clock signals, the pulse-mask unit delays the k-th clock signal for a predetermined time, and the data output unit pauses outputting the print data signal. After the predetermined time, the pulse-mask unit and the data output unit continue to output the rest of the clock signals and the print data signal.
