Description

Burn foreign body inspection machine{Apparatus for testing}

The present invention relates to an image foreign matter inspector, and more particularly, to an image foreign matter inspector capable of performing both electrical and image tests of the image sensor, and moving the lens and the image sensor to optimal positions, respectively.

In general, an image sensor is an element that outputs different brightness and wavelengths of a subject as electrical signal values at a signal-processing level using properties of semiconductors that respond to light. Image sensor chip can transmit/receive or power electric signals and other signals of the captured image, which are arranged in the periphery of the pixel and the pixel area that senses the image in the center of the device. And a bonding pad for receiving. After the image sensor chip is packaged, it is mounted on the camera module. However, the defect caused by foreign matter such as dust during the packaging process of the image sensor chip itself or the image sensor chip is most fatal and frequently occurs. Therefore, after the image sensor chip is manufactured, an electrical test and a probe test to test whether each pixel operates are performed, and even after packaging the image sensor chip, an image resulting from defects or foreign matter generated during the packaging process The sensor is being tested for defects.

Conventional test devices have an electrical test function that simply tests for electrical defects by connecting an image sensor to an external terminal. After placing an optimized lens on the image sensor and irradiating it with light, it is photographed with the image sensor. Until the image test to determine whether the image was defective according to the presence or absence of foreign matter such as black spots or stains on the image, it could not be performed. Accordingly, a separate image test apparatus was required. In addition, in the case of the image test apparatus, a transfer device is provided to freely move the lens in the X-axis, Y-axis and Z-axis directions to optimize the position of the lens disposed between the image sensor and the light source. There was a problem in that the test device occupied a lot of space due to the large volume.

Accordingly, an inspection device having a structure capable of performing both electrical and image tests and moving the lens and the image sensor to the optimum position is required.

8 is an operation diagram showing a state in which the device fixing unit slides in the vertical direction.

When the substrate 41 is to be slidingly moved downward, as shown in Fig. 8A, the control screw 443 is rotated in one direction, for example, counterclockwise. When the control screw 443 is rotated in one direction, the degree of coupling between the control screw 443 and the fixed body 441 is variable, so that the moving body 442 slides downward, thereby engaging the moving body 442 The substrate 41 can also slide downward.

Conversely, when the substrate 41 is to be slid upward, the control screw 443 is rotated in another direction, for example, clockwise, as illustrated in FIG. 8B. When the control screw 443 is rotated in the other direction, the degree of engagement between the control screw 443 and the fixed body 441 is variable, so that the moving body 442 slides upward, thereby causing the substrate 41 to also move upward. Can slide.
