Description
Technical Field
[0001] The invention belongs to the field of detection technology, in particular to a fully automatic detection device for semiconductor packaging products. Background Art
[0002] Packaged semiconductors must undergo multiple tests and be classified and graded by sorting machines to ensure product reliability and yield. Semiconductor technology supports a variety of application scenarios such as integrated circuits, optoelectronic devices, and power devices. Its manufacturing equipment (such as high-precision lithography machines and automated sorting machines) and process innovations continue to promote the miniaturization and high performance of electronic equipment.
[0003] In the field of semiconductor manufacturing, product quality control is of vital importance, and defect detection is a key link in ensuring product quality. During the production process of semiconductor packaging products, due to various process factors, many defects such as scratches on the chip surface, solder joint defects, and cracks inside the package may appear. If these defects cannot be detected in a timely and accurate manner, they will seriously affect the performance and reliability of semiconductor products, and then cause electronic equipment failures, resulting in huge losses to users. For example, the Chinese invention patent with the publication number CN116273960A, entitled "An Automated Inspection Device for Semiconductor Devices," discloses a device comprising a loading section, a conveying section, an inspection section, and a receiving section. The loading section is configured to transport a magazine containing semiconductor devices to be inspected to a predetermined location and sequentially transfer the frames containing the semiconductor devices to be inspected in the magazine to the conveying section. The conveying section includes a separately placed conveyor belt mechanism and a lifting mechanism. The conveyor belt mechanism delivers the frames to the inspection station. The lifting mechanism lifts the semiconductor devices to be inspected and also replaces the inspected semiconductor devices in the frames. The inspection section performs defect inspection on the lifted semiconductor devices to be inspected. The receiving section receives the inspected semiconductor devices and frames into the magazine. The lifting mechanism lifts the semiconductor devices and then allows the inspection section to move, preventing equipment vibration from affecting the position of the semiconductor devices.
[0004] The above-mentioned equipment sets the detection position on the conveying part. The conveying part will generate vibration during operation. This vibration will be transmitted to the frame where the component to be tested is located, causing the component to be tested to shake, thereby affecting the detection accuracy. In order to solve this problem, some solutions in the existing technology set a lifting mechanism to lift the product to be tested from the tray and then perform detection through the movement of the detection part, so as to avoid the influence of the vibration of the conveying part on the position of the semiconductor device. However, although this solution solves the vibration problem to a certain extent, its detection mode will still be affected by the close-range conveying components, and there will be limitations. It is impossible to achieve fully automated detection, the detection efficiency is low, and the random inspection process relies on manual random picking, and the accuracy and reliability of the random inspection are difficult to guarantee.
[0005] Therefore, in order to solve the above problems, a fully automatic detection device for semiconductor packaging products is proposed. Summary of the Invention
