As a core competitive product, the chip is only two or three centimeters in size, but it is densely covered with tens of millions of lines, each of which is neatly arranged. It is difficult to complete the high-precision and high-efficiency detection of chip size with traditional measurement techniques. The vision measuring machine is based on image processing technology, which can quickly obtain the geometric parameters of the object through image processing, and then analyze it through software, and finally complete the measurement.
With the rapid development of integrated circuits, the chip circuit width is getting smaller and smaller. The Chengli optical image measuring machine magnifies a certain multiple through the microscopic optical system, and then the image sensor transmits the microscopic image to the computer, and then the image is processed. processing and measurement.
In addition to the conventional size of the core point of chip detection, the detection target focuses on the vertical distance between the pin vertex of the chip and the solder pad. The bottom end of the pin does not fit together, and there is leakage of welding, and the quality of the finished product cannot be guaranteed. Therefore, our requirements for dimensional inspection of optical image measuring machines are very strict.
Through the CCD and lens of the image measuring machine, the size features of the chip are captured, and high-definition images are quickly captured. The computer converts the imaging information into size data, performs error analysis, and measures accurate size information.
For the core dimension testing needs of products, many large enterprises will choose trusted partners. With years of successful experience and resource advantages, Chengli provides customers with targeted vision measuring machines, which are equipped with imported CCDs and lenses for the core size detection of chips. Take the width of the pin and the height of the center position, it is fast and accurate.
