Abstract: The present disclosure provides a surface mount data conversion method, system, medium and apparatus based on a component three-dimensional database. The surface mount data conversion method based on a component three-dimensional database includes: creating a component 3D database required in a circuit board designing stage and creating a production process template library required in a circuit board production stage; and performing data conversion on the component 3D database and the production process template library to generate a component image library for use in the production stage. The present disclosure can avoid repeated work, achieve real-time update and match of production data, and reduce the error rate caused by the production data during circuit board production.

Abstract: The disclosure provides a bifunctional composite membrane, a preparation method and use thereof, and a method for removing a plasticizer in liquor. The bifunctional composite membrane includes a supporting membrane and a dense layer which covers a surface of the supporting membrane, wherein the supporting membrane includes a filtering membrane and an adsorbent, and the adsorbent is dispersed in a pore structure of the filtering membrane.

Abstract: A system-in-package technology-based process design method and system, a computer readable storage medium, and a device. The system-in-package technology-based process design method includes: acquiring design data of a layout and three-dimensional model data associated with the layout; associating and matching the design data with the three-dimensional model data according to the designed components' attribute information in the design data, and assembling the design data and the three-dimensional model data into an integrated package model; and performing assembly process analysis on the integrated package model to identify unreasonable design points used for design modifications and references, or directly exporting, from the integrated package model, a packaging process manufacturing program for fabrication.

Abstract: Provided are a polyphenol-rich and low-sugar beverage of fermented jujube pulp and a preparation method thereof. The fermented jujube pulp beverage is prepared with a method including the following steps: (1) selecting jujubes that are free of rot and are not insect-eaten, rinsing with pure water, pre-boiling in boiling water, and removing cores; (2) beating the jujubes whose cores are removed in step (1) into a beating machine to obtain a jujube pulp; (3) pouring the jujube pulp in step (2) into a colloid mill for processing to refine jujube peels to obtain a refined jujube pulp; (4) subjecting the refined jujube pulp to ultra-high-pressure sterilization; and (5) inoculating Streptococcus thermophilus into the jujube pulp after the sterilization in step (4), and performing a fermentation cultivation to obtain a fermented jujube pulp.
