Problems solved by technology

[0002] With the diversification and complexity of semiconductor products and the improvement of product quality standards, the semiconductor packaging industry needs to monitor the quality of the product, check the appearance and size of the product and other parameters, and put the product on the tooling in related technologies , and then place it under X-rays to observe and measure the size of the product. Since the semiconductor product has two sides, one side of the semiconductor product is mounted with a chip, and the other side is not mounted with a chip, and the related design of the tooling can only check the mounting of the semiconductor product. On one side of the chip, the surface without the chip cannot be inspected, and the quality risk of the product cannot be monitored in time. In addition, in the prior art, the workpiece under inspection cannot be automatically turned over, resulting in a decrease in detection accuracy and efficiency. Therefore, a A device that can detect both sides of a semiconductor workpiece. The Chinese utility model patent with the publication number CN212721299U discloses a detection tool and a detection system. The detection tool is used for semiconductor workpiece detection. The detection tool includes a tool bracket and a baffle. The baffle plate is movably connected with the tooling bracket, and surrounds to form a placement groove, the placement groove is used to limit the workpiece, the baffle plate is used to adjust the size of the placement groove, and the bottom wall of the placement groove is set There is a way out
This prior art aims to provide a detection tool that is convenient for inspecting the surfaces on both sides of semiconductor workpieces. The detection tool effectively improves the product yield, and at the same time, it can realize adjustment and improve the versatility of the detection tool. However, this prior art still exists The following problems: (1) The semiconductor workpiece cannot be clamped and fixed; (2) It cannot be automatically turned over during the detection process, and the use efficiency is low. Therefore, the present invention provides a double-sided detection device for semiconductor workpieces, which can effectively solve the above-mentioned technologies question
