Semiconductor industry industrial machine vision applications are more mature
Semiconductor industry has the characteristics of high integration and high fineness, is the earliest large-scale application of machine vision technology. The application of machine vision in the semiconductor industry involves the detection of semiconductor appearance defects, size, quantity, flatness, distance, positioning, calibration, solder joint quality, curvature, etc. In particular, the inspection, positioning, cutting and packaging process throughout the wafer fabrication requires the assistance of machine vision technology.
In the wafer manufacturing stage, machine vision is mainly used for wafer inspection and sorting; in the wafer manufacturing stage, machine vision is mainly used for precision positioning and minimum scale detection; in the packaging test stage, the importance of machine vision technology is more prominent, wafers in the cutting process need to use machine vision systems for accurate and rapid positioning, if the positioning error, the entire wafer will be scrapped, in the entire cutting process also Need machine vision system for the entire positioning guidance, the current machine vision products in the guidance process has been both the weld line drop detection function; wafer cutting will continue to use machine vision products to identify non-defective products into the placement process after completion; in the placement process, the core architecture for vision plus motion - the need for machine vision products through Identify the lens position and angle, and guide the motor to correct the angle of the wafer after picking up to the designated position on the PCB placement.
VisionChina (Shenzhen) 2021 will be held on November 23-25 at the Shenzhen International Convention and Exhibition Center (Baoan New Hall). 200+ exhibitors will bring the industry's latest products and cutting-edge technologies. This issue continues to "reveal" new machine vision products that can be applied to the semiconductor industry, covering sensors, cameras, code readers, vision software and vision solutions. Come and see what's on display!

# Spectral Confocal Single Point Sensor CHRocodile Mini
The new CHRocodile Mini sensor enables high-precision contact-free distance and thickness measurements.The CHRocodile Mini is also very flexible in tight spaces. The compact controller and the optical probe are connected via fiber optics. This makes it possible to separate the optical probe from the controller separately. In addition, the probe does not contain any moving parts or heat generating electronics that would affect the accuracy of the measurement.
Application scenarios: Position, size, shape and contour determination (e.g. microelectronic components), roughness measurement (e.g. tool surfaces) and thickness measurement of glass or plastic coatings

# IC Inspection
IC chips are inspected for chip quality using a fully automatic IC taping machine before leaving the factory, rejecting unqualified IC chips and encapsulating qualified IC chips into the material tape. The vision module of the automatic IC taping machine mainly detects the presence or absence of chips in the tape, positive or negative, pin abnormalities (missing pins, deformation, unqualified pin spacing), pin parallelism, chip surface characters and screen printing quality.
Recommended products: Vieworks' VC and VT series cameras
· Ultra-small appearance design, easy to integrate
· Highly reliable image presentation, ensuring consistency of high-speed capture images
Application scenario: Micro electronic device inspection, and capacitor, resistor, diode and other components inspection and banding, etc.
