The following topics are dealt with: assembly and manufacturing technology; electronic circuits; electronics systems and power electronics; microsystems packaging; optoelectronics and advanced communication packaging; applied reliability and thermal management; emerging technologies and trends in advanced packaging; and challenge in global education.
Vapor phase soldering (VPS) has been investigated to improve the knowledge about the vapor generation, expansion and condensation processes. Measuring methods for the investigations have been developed and applied. In an experimental VPS system the following parameters have been studied during the heating up and cooling down processes: the temperature distribution in the vessel by measurements using...
As elements of interconnection structures at level two in electronic packaging, the pads could be considered as a particular solution into a virtual space defined by the materials, geometry, surface finishes and substrate. The assembling processes emphasize the substrate contribution over thermal mass and heat transfer. Each of the pad particular solution defined in the design stage will have unique...
The solder paste printing is one important part of the manufacturing process. More than 50% of all defects of SMT-boards are caused by the printing process. Six-sigma-quality is one common important goal of manufacturing processes. Another criterions or such a quality are a defect rate of about 3,4 DPM (defects per million) or a process capability Cpk > 1,5. The printed solder paste volume, the...
The compliancy with RoHS directives as well as the trend towards green technologies and green processes has been the main driver for the paste manufacturers. One direction that has proven to be worth while exploring is the one towards low melting point alloys that will enable energy savings during the manufacturing processes. Last but not least these emerging alloys will add an extra benefit to the...
Radio communications is spreading more increasingly and people exposure to non-ionizing electromagnetic fields has increased due to emitting antennas. Human beings are complex electrochemical systems that communicate with the environment through electrical pluses. Electromagnetic field penetrates the human body and can alter functions of his cell, tissue and organs by modifying the biochemical processes...
Readers produced so far by Frosch Electronics were intended for RFID tags conforming to the FDX protocol. We present schematics achieving the addition of the HDX protocol, turning the readers into multifunctional ones. We discuss the issues of transient effects and equality of bit amplification, that have influence on the reliability of HDX data decoding. Finally we present some simulation tools that...
A tag simulator is a device that can exchange data with an RFID reader in the same way as a real transponder. It may be of help for reader developers in the process of testing the device response and adjusting the communication algorithms. It may equally help system integrators in testing and tuning the performance of the complete RFID system that comprises the readers, the network to which they are...
This technique can be used in wireless sensor networks which do not have a specific layer or function for routing. It is not necessary to know all the nodes that make up the route, only the neighbor node that provides the shortest route, the one that is delivering the message to the gateway with as few hops as possible. The algorithm can be easy implemented in the CPU of each node using C or Assembler...
The goal of the present contribution is to describe some special aspects presented on literature, in order to understanding the dynamic performance of car equipped with Regenerative Breaking System and preliminary work for building one practical implementation for commercial cars. During deceleration, these vehicles are able to recuperate energy of motion as electrical energy with their built-in electrical...
Radio signals based indoor location systems is a hot topic. Even many papers deals with this subject, and some solutions were tested, currently we have no mature commercial implementations. Based on WLAN, RFID, WSN, ZigBee or proprietary solutions, location systems working principles implies the measurement of radio signals. Due to propagation issues in real working conditions, the practical demonstrated...
EuroTraining is the part of the EC initiated Europractice service, which aims to stimulate the wider exploitation of state-of-the-art micro/nano electronics and microsystem technologies by the European industry and academia. EuroTraining invites engineers and scientists from companies, SMEs, universities and institutes to upgrade their knowledge by professional and awareness courses entitled “Design...
The paper presents a software application for automated evaluation of students with quiz testes which doesn't use computer for every participant at the test, though maintaining the advantage of automated assessment of computer based systems. The benefits of the application, regardless the automated evaluation, are related to the possibilities of generating a large number of different tests (practically...
Platinum thin film layer's long-term stability, repeatability, fast response time, and wide temperature range make it a useful choice in many applications. As a result, platinum resistance temperature devices (RTD) are known as the most reliable standard available for temperature measurements. In this paper we focus on the pulsed stress behavior of the platinum thin film layer, used as a conductive...
Electrical as well as mechanical properties of electrically conductive adhesives can be modified by addition of different types of nanoparticles. It has been investigated if changes of the resistance of adhesive joints caused by thermal ageing will differ in dependence on the type of nanoparticles added into adhesives. It has been found that adhesive joints formed of adhesives modified such the way...
Present research deals with comparative studies, analysis and experiments between three types of supercapacitors packs, in order to obtain the optimal structures for applications in which they are integrated. Two of proposed packs are high voltage used in electrical vehicle sphere and one is realized for low power circuits from electronic application. A summary review regarding the supercapacitors...
