SAS软件对喷墨印花打样重现性的提高

为减少涂料印花目标色和涂料墨水喷墨印花的颜色差异,将喷墨印花技术用于涂料圆网或平网印花前期的打小样环节中,改变了在图像处理软件中直接输入涂料印花目标样Lab值的传统喷墨印花方法。该方法首先对输入图像处理软件中的Lab值与喷墨印花织物测出的Lab值进行比较,利用SAS软件对数据进行分析,再建立涂料印花目标色与喷墨打印后织物颜色的函数校正关系。结果表明,通过一次或几次SAS软件拟合函数校正,减少了喷墨印花打样颜色与目标色之间的色差,提高了喷墨印花打样与涂料印花的重现性,不仅可以节约打样成本,而且能够更好地配合大生产过程。

Highly mechanical and high-temperature properties of Cu–Cu joints using citrate-coated nanosized Ag paste in air

Today, a growing number of third-generation semiconductor-based power devices are used in products that can continuously operate at high temperatures for extended periods of time. Hence, traditional tin-lead and lead-free solders are no longer suitable for modern electronic packaging. A common method is to apply Ag paste for bare Cu–Cu joints under an inert or reductive atmosphere. In this study, the citrate-coated nanosized Ag paste was utilized to generate robust bare Cu–Cu joints under atmospheric conditions. The average size of citrate-coated Ag particles was approximately 4.76 ?nm after being cleaned by deionized water and acetone. The effects of process parameters, such as cleaning, joining temperature, holding time, and joining pressure, on the mechanical properties of the bare Cu–Cu joints were thoroughly investigated. Increasing washing and joining temperatures resulted in a shear strength increase of up to 28.2 ?MPa ?at a joining temperature of 260 ?°C after seven washes. In addition, a holding time of 30 ?min and a joining pressure of 1 ?MPa were selected as optimal process conditions for the application of citrate-coated nanosized Ag paste onto bare Cu–Cu joints. The newly developed Cu–Cu joints showed excellent thermal stability at 150 ?°C using the citrate-coated nanosized Ag paste. After long-term aging, the joints exhibited stability at 250 ?°C for 144 ?h, indicating a good high-temperature reliability for three-dimensional integrated circuits (3D ICs) fabricated under atmospheric conditions.

In view of the lack of research on the information model of tufting carpet machine in China, an information modeling method based on Object Linking and Embedding for Process Control Unified Architecture(OPC UA) framework was proposed to solve the problem of "information island" caused by the differentiated data interface between heterogeneous equipment and system in tufting carpet machine workshop. This paper established an information model of tufting carpet machine based on analyzing the system architecture, workshop equipment composition and information flow of the workshop, combined with the OPC UA information modeling specification. Subsequently, the OPC UA protocol is used to instantiate and map the information model, and the OPC UA server is developed. Finally, the practicability of tufting carpet machine information model under the OPC UA framework and the feasibility of realizing the information interconnection of heterogeneous devices in the tufting carpet machine digital workshop are verified. On this basis, the cloud and remote access to the underlying device data are realized. The application of this information model and information integration scheme in actual production explores and practices the application of OPC UA technology in the digital workshop of tufting carpet machine.     

Study On the Method for Evaluating the Compatibility of Poly vinyl Alcohol - starch Pastes

A revising method for evaluating the separation behavior of polyvinyl alcohol - starch pastes used as warp sizes had been studied and developed. Cosolvent method involves two important indexes for appraising the separation behavior: (l) initial demising time, and (2) subsidence ratio. However, they sometimes gave confused results because of the different measuring conditions. For obtaining the indexes accurately, the measuring parameters such as paste concentration, component content, and subsidence period of time were carefully studied and proposed. Besides accuracy, the proposed condition could give larger measuring scope and higher sensitiveness than the old one. Moreover, the influences of the paste concentration, component content, and molecular structure of polyvinyl alcohol upon the separation were also investigated. The experiments indicated that the paste concentration and starch content had much effect on the phase separation, whereas the influence of the molecular structure of polyvinyl alcoho
