  • Method for pins detection and insertion of electronic component
    Patent number: 9456536
    Abstract: A method and system for pins detection and insertion of an electronic component are provided. The method includes picking an electronic component having a plurality of pins by a pick and place device, acquiring a plurality of serial images with respect to the plurality of pins at different height along an image acquiring direction by an image acquiring device, separately detecting image positions corresponding to the plurality of pins in the plurality of serial images, determining whether the electronic component is qualified according to a distance between the image positions of two adjacent pins, and if the electronic component is qualified, inserting the electronic component to a circuit board according to a position relationship between the image positions of the pins and a geometric center position of the pick and place device.

  • Protection gas control method for non-sealed process chamber
    Patent number: 7809474
    Abstract: A protection gas control method for a non-sealed process chamber including the steps of activating a protection gas control apparatus while coupling a protection gas to a plurality of throttle valves, opening all the throttle valves for a pre-determined period of time, closing at least one of the throttle valves if the oxygen concentration in the chamber is smaller than or equal to a first target value, determining whether the oxygen concentration in the chamber is smaller than or equal to a second target value, and stopping supplying the protection gas when the temperature of the chamber is lower than a pre-determined temperature.
