Description

Technical Field

[0001] This application relates to the semiconductor field, and more particularly to a carrier disk device. Background Technology

[0002] In semiconductor manufacturing and packaging testing, carrier trays are crucial tools for storing and transporting electronic components such as chips. Traditional carrier trays typically only have simple storage functions and lack the ability to precisely locate and inspect electronic components. After electronic components are mounted on the carrier tray, the lack of an effective recording and tracking mechanism makes it impossible to trace the specific location and status of the products. This not only increases the difficulty of production management but also makes it difficult to quickly locate and resolve problems when they occur.

[0003] During the post-packing inspection process, products need to be manually picked up and turned. This manual operation can easily cause physical damage to the products, such as scratches and cracks. Furthermore, manual operation significantly extends working hours, increases labor costs, and operator fatigue also increases the risk of errors. All these factors seriously affect product quality and production efficiency.

[0004] Carrier trays cannot be tracked in real time during transportation, making them prone to loss, collisions, and drops. These problems not only damage the product but also affect production schedules. For example, if a carrier tray is lost during transportation, the entire batch of products may not be packaged and tested on time, thus impacting the overall production plan. Furthermore, collisions and drops can damage the internal structure of the product, further reducing product quality.

[0005] Post-packing inspection typically relies on manual visual inspection, which is not only time-consuming but also prone to missed or false positives. The inefficiency of manual inspection not only prolongs working hours but also wastes significant human resources. Especially in high-volume production lines, manual inspection has become a bottleneck restricting production efficiency. Furthermore, manual inspection is highly subjective; different operators may have different judgment standards, making it difficult to guarantee the consistency and accuracy of inspection results.

The base 10 is designed as a detachable modular structure for easy maintenance and upgrades. For example, the number of carrier trays 20 can be increased or decreased according to production needs. The base 10 is provided with an openable cover, which in one embodiment can be a flip-top or a sliding type.

In one embodiment, the robotic arm can be connected to the controller 60 via a wired or wireless means.

[0038] A positioning unit 30 is disposed in the base 10 and is used to locate the orientation of the carrier plate 20. The positioning unit 30 includes an outdoor locator and an indoor locator for precise positioning of the carrier plate 20.

In practical applications, multiple cameras can be used to capture images from different angles according to the environment and inspection requirements to ensure comprehensive coverage. Alternatively, a movable camera can be used to acquire images of the electronic components. The acquired images are then processed using image processing algorithms to identify defects in the electronic components.

By integrating multiple sensors and a control system, this device achieves efficient and accurate detection of electronic components. The carrier tray device can work online with a PNP system to record the position of electronic components before a specific operation, thereby improving the transparency and traceability of the production process. This allows for rapid and effective analysis of commonalities in the appearance and size issues of electronic components and traceability of batch sources.
