The chip, as the core competitive product, is only two or three centimeters small, but it is densely covered with tens of millions of lines, each of which is neatly arranged. The traditional measurement technology is difficult to complete the high precision and high efficiency measurement of chip size. Based on image processing technology, the visual measuring machine can quickly obtain the geometric parameters of the object through image processing, and then complete the measurement through software analysis.
With the rapid development of integrated circuits, the width of the chip wire is getting smaller and smaller. Handing optical image measuring machine amplifies a certain multiple through the microscopic optical system, and then transmits the microscopic image to the computer by the image sensor, and then carries on the image processing and measurement.
In addition to the conventional size, the detection core point of the chip focuses on the vertical distance between the pin apex of the chip and the welding disc. If there is a deviation in the distance between the pin apex and the welding disc, it will not only lead to the joint between the patch welding and the bottom of the pin, but also lead to welding leakage, and the quality of the finished product can not be guaranteed. Therefore, we have very strict requirements for dimensional detection of optical image measuring machines.
Through the CCD and lens of the image measuring machine to capture the size characteristics of the chip, quickly capture the high-definition image, the computer converts the imaging information into size data, carries out error analysis, and measures the accurate size information.
For the core size detection needs of products, many large enterprises will choose a trusted partner. With many years of successful experience and resource advantages, Handing provides customers with targeted vision measuring machine. For the core size detection of chip, the imported CCD and lens are configured. By placing the workpiece in the visual position of the field of view, the program is automatically driven to grasp the width of the pin and the height of the center position, its measurement speed is fast and high precision.
