As China becomes one of the world’s largest auto markets, the relevant manufacturing industries are also booming; leading to a strong demand for highly accurate manufacturing machines. During the assembly process in an automotive plant, bolt tightening is a critical task to ensure car safety and needs to precisely control torque and rotation angle. Its tightening speed also has to be adjusted according to softness and hardness of bolt material as well as a degree of fitting tightness. More

In order to create even smaller devices, silicon wafers have had to greatly improve their quality. During their manufacturing process, wafer suppliers must continue to develop high-yield, simplified processes. Advanced Process Control System (APC) has been used for many years to produce a superior product at a competitive cost. As a result, accurate data collection is the key because APC technology relies on metrology applications. There are many repeated processes in the manufacture of wafers, all of which adopted fault detection and classification system (FDC) - a subsystem of APC - for the automatic detection of equipment problems and the execution of stoppages and alarms.
