  • Testing apparatus for light emitting diodes
    Patent number: 9429617
    Abstract: A testing apparatus for flip chip LEDs includes a transparent substrate, a spacing member, a flexible transparent carrier, and a vacuum generator. The spacing member is configured on a first surface of the transparent substrate. The flexible transparent carrier is removably assembled to the spacing member so that a closed space is formed by the flexible transparent carrier, the spacing member, and the first surface of the transparent substrate. The vacuum generator is connected to the closed space for pumping air out of the closed space, and then a part of the transparent substrate clings to the first surface to form a testing area for loading the flip chip LED.
    Type: Grant
