The invention discloses a preparation method of a carrier plate structure, the carrier plate structure and a semiconductor packaging structure. The preparation method of the support plate structure comprises the following steps: providing a support plate, wherein the support plate is provided with a first surface and a second surface opposite to each other in a first direction; modifying the support plate at a part of positions by using a laser induction process from one side of the support plate in the first direction, so that the support plate is provided with a modified area and a non-modified area, and the sizes of the modified area and the non-modified area in the first direction are equal to the size of the support plate in the first direction; performing etching treatment on the first surface in the modification area to form a first hole section which does not penetrate through the carrier plate; preparing a first conductive structure in the first hole section; performing etching treatment on the second surface in the modification area to form a second hole section communicated with the first hole section; and at least preparing a second conductive structure electrically connected with the first conductive structure into the second hole section.

This invention discloses a portable sediment sampler with a multifunctional collection structure for shallow sea use. It includes a connecting cylinder with a T-shaped operating handle fixedly connected to its top. A connecting layer column is movably installed at the bottom of the connecting cylinder, and a sampling mechanism is fixedly installed at the bottom of the connecting layer column. The sampling mechanism comprises a vertical cylinder, a compression spring, a sediment sampling cylinder, a first slot, a second slot, and a folded cylindrical plate. The sampling mechanism also includes a sealing cylinder, a threaded ring, a filter cotton sheet, and a filter plate. This sampler can simultaneously sample seabed sediment and seabed water, and can separate the sediment from the seabed water. During use, the sampler can be fixed to the side plate of a small fishing boat using an N-type mounting bracket, an adjusting rod, and a pressure disc. Furthermore, during the deep-sea sampling process, the support mechanism effectively prevents the sampling mechanism from tilting. The sampler also has an anti-loss function.

The application relates to the technical field of electric digital data processing, and particularly discloses a product information risk assessment method and system based on a large model, which comprises the following steps: simultaneously scanning source code and products by a scanner to generate a source dependency list and a product component list, performing main name normalization and alignment through a large model, locking a warehouse and a version according to the source dependency list, analyzing original code by a parser to generate a cross-language path logic group, combining the product component list to correct a real package version, converging into a unified intermediate representation, performing reachability and joint analysis on the unified intermediate representation to obtain a risk candidate path set and complete path scoring, finally, according to a preset weight and a running period evidence, modifying the score, screening out a risk path, matching a disposal strategy, and generating executable strategy code by the large model for risk control of a gateway or a service side.

This invention provides a continuous stepless adjustment device, method, and application for electron beam based on the axial position control of the convergence point, belonging to the field of electron optics adjustment technology. The invention includes an anode body, an anode aperture, an electromagnetic focusing unit, and a fixed single-aperture main aperture, coaxially arranged along the electron beam propagation direction within the lens barrel of an electron optics system. This invention uses the axial position of the electron beam's convergence point relative to the fixed single-aperture main aperture as the control degree of freedom. The electromagnetic focusing unit continuously adjusts the displacement of the convergence point along the optical axis, achieving continuous stepless adjustment of the electron beam. By completely eliminating the mechanical moving parts of the aperture, this invention not only achieves continuous and smooth adjustment of the electron beam but also fundamentally avoids the vibration, contamination, and failure risks caused by mechanical movement. This significantly improves the reliability, repeatability, and long-term stability of the electron optics system, while simplifying the system structure and reducing manufacturing and maintenance costs.
