P. Matkowski, Qi Haiyu
Reliability of electronic devices is a crucial scope of interest of the electronic manufacturing industry. The reliability is connected with electrical, thermal and mechanical properties of investigated products. Electrical and thermal properties are investigated during the specified tests such as thermal shocks, temperature, and humidity cycles, dry oven storage. Mechanical properties are concerned of mounted components are mainly problem of the assembly industry. At the present electronic components are mounted to the PCB mostly by surface mount technology (SMT) or flip chip processes. The lead-solders are being presently replaced with lead-free solders or electrically conductive adhesives. It is caused by the European and Japanese restrictions. The restrictions forbid using lead in consumer electronic products because of its harmful influence on beings. The new solders and assembly technology force to the following investigations of reliability of joints. This paper contains information about information tests as accelerated tests commonly used to evaluate fatigue life of interconnections in electronic assembly. In the first part of the paper short review of accelerated tests is presented. Anand's model of the solder joint used in finite elements analysis (FEA) and Darveaux's crack initiation and growth model are also mentioned, The bases of FEA and DOE are beyond the scope of this paper. In the second part of the paper harmonic as well as random variation and two different constructions of shakers, their advantages, limitations and requirements are presented. Characterization of specimen and vibration setup is considered. At the end of the paper vibration test is proposed
电子设备的可靠性是电子制造业关注的一个重要问题。可靠性与所研究产品的电学、热学和力学性能有关。电学和热性能在规定的测试期间进行研究,如热冲击、温度和湿度循环、干燥箱储存。安装部件的力学性能问题是装配行业面临的主要问题。目前,电子元件大多采用表面贴装技术(SMT)或倒装工艺安装到PCB上。目前,铅焊料正被无铅焊料或导电粘合剂所取代。这是由欧洲和日本的限制造成的。由于铅对人体有害,限制规定禁止在消费电子产品中使用铅。新的焊料和装配技术的出现,推动了对接头可靠性的进一步研究。本文介绍了电子组件互连疲劳寿命评价常用的信息加速试验。本文第一部分对加速试验进行了简要回顾。文中还介绍了有限元分析中常用的焊点Anand模型和Darveaux裂纹萌生与扩展模型,有限元分析和DOE的基础不在本文的讨论范围之内。第二部分介绍了振动台的谐波和随机变化以及两种不同的结构,它们的优点、局限性和要求。考虑了试样的特性和振动设置。最后对纸张振动试验提出了建议

Fabrication of a low-voltage light emitting device based on carbon nanotubes and rare-earth doped nanocrystals 基于碳纳米管和稀土掺杂纳米晶体的低压发光器件的制备
P. Psuja, W. Stręk, D. Hreniak
Field emission displays using carbon nanotubes (CNT-FEDs) are ones of the most promising devices which can compete with other technologies such as liquid crystal displays (LCDs). Good picture quality, a low power consumption, a wide work temperature range and a high efficiency of luminescence are the great advantages of that technology. In this work, new and a low-cost method of electrophoretic deposition of CNTs on the ITO-glass slide is presented. Deposition of the light emitting layer was also done by the same method. The Eu3+:Y2O3 nanocrystalline phosphor prepared by modified Pechini method was used as emitting layer in tested the FED construction. The satisfied light intensity was observed under the vacuum level of about 1 times 10-5 Tr, and accelerating voltage of 500 V. Application of other rare-earth ions doped nanocrystalline phosphors in CNT-FED is discussed

Analytical laser model for optical signal integrity analysis 用于光信号完整性分析的解析激光模型
G. Clarici, E. Griese
The design of optical interconnects within an electrical environment requires a close coupling of the respective modeling and simulation tools. For the lasers in optical interconnects exist a number of different models, which usually require detailed and, for the manufacturer, sensitive information concerning the laser structure and therefore the manufacturing process. Similar problems were an issue in electronic system design, but have been solved by employing generic high-level simulation models. Taking the same approach for optical interconnects an analytical approximate solution of the laser rate equations is presented as a first step. Due to its analytical nature, the model can either use parameters derived from the laser structural data or parameters gained from measurement. This is an advantage when dealing with devices with unknown structure
电气环境中光学互连的设计需要各自的建模和仿真工具的紧密耦合。对于光互连中的激光器,存在许多不同的模型,这通常需要详细的,对于制造商来说,关于激光器结构和制造过程的敏感信息。类似的问题在电子系统设计中也存在,但已经通过采用通用的高级仿真模型得到了解决。对光互连采用同样的方法,首先给出了激光速率方程的解析近似解。由于其解析性,该模型既可以使用从激光结构数据中获得的参数,也可以使用从测量中获得的参数。在处理结构未知的设备时,这是一个优势
