According to the continuous development of technologies such as semiconductors and panels, the flatness, hole position and circuit layout accuracy of various types of boards are becoming higher and higher. In today's circuit boards, for example, after manufacturing is completed, Perform various board flatness, hole position, aperture and line detection. In this way, the probability of misuse of the bad board can be reduced to maintain the yield of the product [yield] to prevent subsequent installation of capacitors, inductors, resistors or When the electronic components such as objects are inaccurate, the circuit board and related electronic components are damaged. Due to the increasingly finer integrated circuits, the extremely small defects generated in the process become the key factors affecting the overall quality.

Usually, each process stage relies on the inspection system to control the quality of the product, so the application of the detection system is quite extensive in the semiconductor industry.

However, the conventional inspection machine is designed to have only horizontal X-axis and Y-axis tracks, and then the linearly moving suction unit moves on the X-axis track and the Y-axis track to move the object to the test machine. The area; for example, the suction unit first sucks the object to be tested from the feeding area to the test area, and after the object is tested, moves the tested object from the test area to the discharge area. But with the speed of object testing l, the output bottleneck of the traditional test machine appears on the moving/suction operation of the suction unit. Since the suction unit must perform the suction of the object, the movement of the object, the classification of the object, etc., the time taken for the suction unit to move will It is much longer than the time required for the testing of the object, resulting in idle and paused object testing operations. Furthermore, it is usually only capable of detecting one side of the object, and it is not possible to detect the peripheral and suction surfaces. Therefore, if the peripheral side or the suction surface has a detection requirement, another detection device, a jig or a re-entry is required.
