Progressive transmission line matching when encountering via mismatching 当遇到通过错配时,渐进式传输线匹配
M. Daraban, D. Pitica
When it comes to transmission lines the common causes for signal integrity (SI) problems are the mismatches caused during the routing process. From all the possible causes for mismatches, vias are the most common ones. In the literature, different approaches are proposed to resolve the SI problems caused by vias: stitching vias, matching the driver output impedance to the transmission line's new value [1]. Stitching vias can be used when printed circuit boards (PCBs) are used with more than four layers. Additionally a smaller value for the series-matching resistor improves the signal rise/fall time, but also increases the ringing effect's amplitude. In the paper, a solution for improving the signal at the receiver is proposed that can be used even on four layer PCB. The proposed solution keeps the improvements obtained through matching the driver output to the transmission line's modified impedance, without increasing the ringing effect amplitude.
当涉及到传输线时,信号完整性(SI)问题的常见原因是在路由过程中引起的不匹配。在所有可能导致不匹配的原因中,过孔是最常见的。在文献中,提出了不同的方法来解决由过孔引起的SI问题:拼接过孔,将驱动器输出阻抗匹配到传输线的新值[1]。当印刷电路板(pcb)使用超过四层时,可以使用拼接过孔。此外,较小的串联匹配电阻值可以改善信号上升/下降时间,但也会增加振铃效应的幅度。本文提出了一种可以在四层PCB上使用的接收机信号改善方案。该方案在不增加振铃效应幅度的情况下,保持了驱动器输出与传输线修正阻抗匹配所获得的改进。

On change detection for improved reliability 关于改进可靠性的变更检测
D. Aiordachioaie, M. Andrei
Change detection problem refers to the detection of abnormal regimes and incipient faults of electrical circuits, devices or equipments. The problem is coming more and more important as the requirements for high and constant quality, low maintenance and high reliability of complex electronic products are continuously increasing. Classical methods use statistical signal processing techniques, various frequency transforms and techniques based on models. In all these approaches the moment of change detection must be known as precisely as possible. This work presents preliminary results in solving change detection problem based on two methods. The first one is based on signal modeling and detects changes by observing the changes in the model's parameters. The second one is based on Renyi entropy processing and it uses direct, simple and efficient parameter estimation methods to describe the circuit's behavior. Both methods could serve as references for other more advanced techniques, e.g. based on frequency transforms and complex optimization criteria.
变化检测问题是指对电路、装置或设备的异常状态和早期故障的检测。随着复杂电子产品对高质量、低维护和高可靠性的要求不断提高,这一问题变得越来越重要。经典方法使用统计信号处理技术、各种频率变换和基于模型的技术。在所有这些方法中,必须尽可能精确地知道变化检测的时刻。本文提出了基于两种方法解决变更检测问题的初步结果。第一种方法基于信号建模,通过观察模型参数的变化来检测变化。第二种方法是基于Renyi熵处理,使用直接、简单、高效的参数估计方法来描述电路的行为。这两种方法都可以为其他更先进的技术提供参考,例如基于频率变换和复杂优化准则的技术。

PCB layout optimization for LED backlight module using FEM simulation 基于有限元仿真的LED背光模块PCB布局优化
Aurelian Botau, C. Negrea
Nowadays the size of Liquid Crystal Displays (LCD) displays on the market has a continuous ascending trend which demands higher and higher resolutions. The backlight system of a LCD is the structure that offers light which passes through the liquid crystals layer. No matter what method is used, it has to provide a high luminous intensity and a uniform light distribution on screen visible surface. One significant problem in such designs is the difference in light intensity of individual LEDs due to their different junction temperatures. This paper presents a method of optimization for a LED matrix assembly, where the main purpose is to improve the thermal uniformity on the PCB in order to reduce the luminous flux output difference between the devices, while also maintaining the junction temperatures in the acceptable operating range. As a consequence, the need of custom pattern diffusers used in the LCD displays as light uniformity corrections structures can be eliminated. The method implies defining the geometry for the cooling areas on the PCB by using a specific formula obtained after curve fitting FEM simulation results.
目前市场上液晶显示器(LCD)的尺寸有持续上升的趋势,对分辨率的要求也越来越高。LCD的背光系统是提供通过液晶层的光的结构。无论采用何种方法,都必须在屏幕可见表面提供高的发光强度和均匀的光分布。这种设计的一个重要问题是,由于不同的结温,单个led的光强存在差异。本文提出了一种优化LED矩阵组件的方法,其主要目的是改善PCB上的热均匀性,以减少器件之间的光通量输出差异,同时保持结温在可接受的工作范围内。因此,可以消除LCD显示器中使用的自定义模式漫射器作为光均匀性校正结构的需要。该方法通过对有限元模拟结果进行曲线拟合得到的特定公式来确定PCB上冷却区域的几何形状。

Reducing lead-free soldering failures caused by Printed Circuit Board shrinkage 减少印刷电路板收缩造成的无铅焊接故障
A. Géczy, L. Tersztyanszky, B. Illés, A. Kemler, A. Szabó
The paper presents a novel approach on an emerging problem in lead-free reflow soldering technology. The trend of miniaturized SMD device application and the increasing component density cause newfound problems during the reflow process. In this work, the issue of Printed Circuit Board (PCB) shrinkage is inspected in the environment of automotive electronics production. The shrinkage effect results in linear offset on the double sided PCB along the (XY) dimensions during stencil printing of the second reflow pass. The observed phenomenon causes tombstone and bridging failures on specific fine-pitch SMD components. To investigate and obtain deeper understanding of the phenomenon, a new method was developed for the measurement of shrinkage. The novel measurement method is evaluated with a less-productive, but more precise measurement device. With the collected data it is possible to approximate the overall shrinkage of the given product. After introducing a compensation step on the stencil design (based on the measurements), it is possible to significantly reduce the quantity of failures caused by the shrinkage.
本文针对无铅回流焊技术中的一个新问题,提出了一种新颖的方法。SMD器件小型化的趋势和元件密度的不断提高,导致回流过程中出现了新的问题。本文对汽车电子产品生产环境中印刷电路板(PCB)的收缩问题进行了研究。收缩效应导致双面PCB沿(XY)尺寸在第二次回流通道的模板印刷过程中的线性偏移。所观察到的现象会导致特定细间距SMD组件的墓碑故障和桥接故障。为了研究和更深入地了解这一现象,开发了一种测量收缩的新方法。用一种生产率较低但精度较高的测量装置对这种新型测量方法进行了评价。有了收集到的数据,就有可能近似地计算出给定产品的总体收缩。在模板设计上引入补偿步骤(基于测量)后,可以显着减少由收缩引起的故障数量。

Factors influencing the formation of voids in chip component solder joints 影响芯片元件焊点空隙形成的因素
M. Pantazica, P. Svasta, H. Wohlrabe, K. Wolter
The aim of this paper is to present the most recent results obtained after conducting a complex experiment designed with the help of the Design of Experiments (DoE) method. The purpose of this experiment is to evaluate the dependencies between the layout design and the production quality of surface mount boards. The last part of this experiment is focused on studying the effects of solder voids on the reliability of solder joints. Solder joints are investigated and evaluated with the help of an X-Ray equipment. Based on the X-Ray images, the void area in a solder joint is measured (in pixels). The statistical analysis has revealed that all factors considered to have an influence on the void formation in this experiment are significant. Moreover all the interactions between these factors are statistically significant. The largest void content is obtained in case of microMELF components, chemSn surface finish and solder paste type C. As opposed to our expectations, the void area is the smallest in case of Vapour Phase Soldering.

S. Pop, V. Bande, D. Pitica
This paper presents a data acquisition system used for AC/DC current monitoring. The developed system use the current transducer manufactured by LEM [3]. The output signal of the transducer is a voltage that is proportional to the current magnitude. To compute the current, the outputs signal is sampled with high frequency. The AC rms (root mean square) value is obtained by processing the sample values during the multiple periods of alternative signal. The number of periods is chosen according to the dynamic of process. For data acquisition and processing is used a microcontroller, ATMEGA 328. The acquisition system has six input channels, connected at the 10-bit ADC inputs channels of microcontroller. The ADC has ±2LSB absolute accuracy and the sensor accuracy is of ±1 %. The systematic error has a major component into the total error; this error may be reduced, soft, through the calibration process.

High-low impedance transformer using transmission line method 高低阻抗变压器采用传输线法
R. Fang, Chia-fen Liu, Chieh-Yu Liao, Chun-Long Wang
In this paper, a simple transmission line method is proposed to precisely predict the center frequency of the compact high-low impedance transformer. It has been shown that the center frequency of the return loss stays at 3 GHz even though the electrical length θT reduces greatly. Besides, the compact high-low impedance transformer with θT = 60° yields 35.89% area-saving and maintains the same 15-dB bandwidth as compared with the conventional quarter-wavelength transformer. In order to verify the simulation results, back-to-back transformers are fabricated and measured where the measurement results are in good agreement with the simulation results.

Health is one of the major issues for normal existence of human life and it is a global agenda to increase the health care facilities for the peoples who don't have an immediate access to these facilities and are living in rural and undeveloped areas. From the beginning of twenty first century field of E-health has been developed rapidly to encounter these problems properly. The healthcare infrastructure gaining betterment day by day under the shadow of E-health technologies, where using mobile phones are becoming an efficient tool in monitoring and transmitting different physiological signals. Cardiac sound is an initiative physiological parameter that is helpful for diagnosing changes in physiological conditions and disease. Hence in this research a tele auscultation system is designed for the transmission of cardiac sounds to the medical practitioner from distant place by using an electronic stethoscope through a GSM (Global System for mobile communication) technology. The physiological signals of low frequency and voltages, after amplification and filtration can be easily transmitted with low noise interference in the signal. This portable wireless cardiac sound transmission device can send heart sounds of a patient just in one call. The information about the placement of stethoscope at different position of heart can be transmitted to medical practitioner through a SMS (Short Messaging Service). For the purpose stated a GSM modem of SIM900D is used which is interfaced with a Microcontroller Unit in order to control and send instructions to modem using AT (Attention) commands. Therefore, it is concluded that the cardiac sounds of a patient can be transmitted from the distant areas to the medical practitioner for the purpose of diagnosing many illness of the patients.
健康是人类正常生活的主要问题之一,为生活在农村和不发达地区无法立即获得这些设施的人民增加卫生保健设施是一项全球议程。从21世纪初开始,电子医疗领域得到了迅速的发展,以应对这些问题。在电子医疗技术的影响下,医疗保健基础设施日益改善,使用移动电话正在成为监测和传输不同生理信号的有效工具。心音是一种主动的生理参数,有助于诊断生理状况和疾病的变化。因此,本研究设计了一种远程听诊系统,通过GSM(全球移动通信系统)技术,利用电子听诊器将心音从远处传送给医生。低频率、低电压的生理信号,经过放大和滤波后,可以很容易地以低噪声干扰的信号传输。这种便携式无线心音传输装置可以在一次通话中传送病人的心音。听诊器在心脏不同位置的放置信息可以通过短信传送给医生。为了达到上述目的,使用了SIM900D的GSM调制解调器,该调制解调器与微控制器单元接口,以便使用AT(注意)命令控制并向调制解调器发送指令。因此,可以得出结论,患者的心音可以从远处传递给医生,以诊断患者的许多疾病。

New frontiers in education — Training in Biology for Electrical Engineers 教育的新领域——电气工程师的生物学培训
M. Varga, K. Wolter
We propose a new teaching module called “Biology for Electrical Engineers” that should help engineering students to understand and apply important biological concepts. Until now, only few educational institutes in the world offer similar training despite an increasing tendency of interdisciplinarity across research activities. The teaching resources will include overviews of important biological topics, modeling and computational as well as laboratory exercises. The knowledge and expertise acquired should support engineers in designing and fabricating more prominent biosensor- and electronic devices.
我们提出了一个新的教学模块,称为“电气工程师生物学”,应该帮助工程专业的学生理解和应用重要的生物学概念。到目前为止,世界上只有少数教育机构提供类似的培训,尽管跨研究活动的跨学科趋势日益增加。教学资源将包括重要生物学主题的概述,建模和计算以及实验室练习。所获得的知识和专业知识应支持工程师设计和制造更突出的生物传感器和电子设备。
