Book excerpt: The technical application of screen and stencil printing has been state of the art for decades. As part of the subtractive production process of printed circuit boards, for instance, screen and stencil printing play an important role. With the end of the 20th century, another field has opened up with organic electronics. Since then, more and more functional layers have been produced using printing methods. Printed electronics devices offer properties that give almost every freedom to the creativity of product development. Flexibility, low weight, use of non-toxic materials, simple disposal and an enormous number of units due to the production process are some of the prominent keywords associated with this field. Screen printing is a widely used process in printed electronics, as this process is very flexible with regard to the materials that can be used. In addition, a minimum resolution of approximately 30 µm is sufficiently high. The ink film thickness, which can be controlled over a wide range, is an extremely important advantage of the process. Depending on the viscosity, layer thicknesses of several hundred nanometres up to several hundred micrometres can be realised. The conversion and storage of energy became an increasingly important topic in recent years. Since regenerative energy sources, such as photovoltaics or wind energy, often supply energy intermittently, appropriate storage systems must be available. This applies to large installations for the power supply of society, but also in the context of autarkic sensors, such as those used in the Internet of Things or domestic/industrial automation. A combination of micro-energy converters and energy storage devices is an adequate concept for providing energy for such applications. In this thesis the above mentioned keywords are addressed and the feasibility of printed thermoelectric energy converters and supercapacitors as energy storage devices are investigated. The efficiency of thermoelectric generators (TEG) is low, but in industrial environments, for example, a large amount of unused low temperature heat energy can be found. If the production costs of TEGs are low, conversion of this unused heat energy can contribute to increasing system efficiency. Additionally, printing of supercapacitor energy storage devices increases the usability of the TEG. It is appropriate to use both components as complementary parts in an energy system. Den tekniska tillämpningen av skärm- och stencilutskrift har varit toppmoderna i årtionden. Som en del av den subtraktiva produktionsprocessen av tryckta kretskort spelar exempelvis skärm- och stencilutskrift en viktig roll. I slutet av 1900-talet har ett annat fält öppnat med organisk elektronik. Sedan dess har allt fler funktionella lager producerats med hjälp av tryckmetoder. Tryckta elektronikanordningar erbjuder egenskaper som ger nästan all frihet till kreativiteten i produktutvecklingen. Flexibilitet, låg vikt, användning av giftfria material, enkelt bortskaffande och ett enormt antal enheter på grund av produktionsprocessen är några av de framträdande nyckelord som hör till detta område. Skärmtryck är en allmänt använd process i tryckt elektronik, eftersom processen är mycket flexibel med avseende på material som kan användas. Dessutom är en minsta upplösning på cirka 30 µm tillräckligt bra. Bläckfilmens tjocklek, som kan styras över ett brett område, är en extremt viktig fördel med processen. Beroende på viskositeten kan skikttjockleken på flera hundra nanometer upp till flera hundra mikrometer realiseras. Energikonvertering och lagring har blivit ett allt viktigare ämne de senaste åren. Eftersom regenerativa energikällor, såsom fotovoltaik eller vindkraft, ofta levererar energi intermittent, måste lämpliga lagringssystem vara tillgängliga. Detta gäller stora installationer för samhällets strömförsörjning, men också inom ramen för autarkiska sensorer, som de som används i saker av saker eller inhemsk / industriell automation. En kombination av mikroenergiomvandlare och energilagringsenheter är ett lämpligt koncept för att tillhandahålla energi för sådana applikationer. I denna avhandling behandlas ovan nämnda nyckelord. Genomförbarhet av tryckta termoelektriska energiomvandlare och superkapacitorer som energilagringsenheter undersöks. Effektiviteten hos termoelektriska generatorer (TEG) är låg, men i industriella miljöer kan exempelvis en stor mängd oanvänd låg temperatur värmeenergi hittas. Om produktionskostnaderna för TEG är låga kan konvertering av denna oanvända värmeenergi bidra till ökad systemeffektivitet. Dessutom ökar utskrift av superkapacitorer användbarheten hos TEG. Det är lämpligt att använda båda komponenterna.

This book was released on 2003-07-02 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Printing Industry generates a wide range of products which require in every step of our everyday life. Starting from newspapers, magazines, books, post cards to memo pads and business order forms each are the products of printing industry. Printing is a process for reproducing text and image, typically with ink on paper using a printing press. There are various types of printing process for example offset printing, modern printing, gravure printing, flexographic printing etc. Offset printing is a widely used printing technique where the inked image is transferred from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographic process, the offset technique employs a flat image carrier on which the image to be printed obtains ink from ink rollers, while the non printing area attracts a film of water, keeping the non printing areas ink free. Gravure printing is a printing technique, where the image to be printed is made up of small depressions in the surface of the printing plate. It is divided into three broad product areas; packaging printing, publication printing and speciality printing. Printing technology is often carried out as a large scale industrial process, and is an essential part of publishing and transaction printing. This is the age of hi fi, jets and computers. Rapid advancements in science and technology have made their impact on the printing industry of the world too. The old techniques of printing have become obsolete and made way for the new technology.

Download or read book Inkjet and Screen Printing for Electronic Applications written by Beatriz Medina Rodríguez and published by . This book was released on 2016 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Printed electronics (PE) is a set of printing methods used to create electrical devices on various substrates. Printing typically uses common printing equipment suitable for defining patterns on material, such as screen printing, flexography, gravure, offset lithography, and inkjet. Electrically functional, electronic or optical inks are deposited on the substrate, creating active or passive devices. PE offers a great advantage when compared to traditional processes or microelectronics due to its versatility, low manufacturing cost and the possibility of generating flexible circuit componentsi. Furthermore, these techniques are suitable for roll-to-roll processes and open the possibility for printing large areas and in a large-scale production. . The selection of the printing technique is crucial to achieve a good result and it will largely depend on both, the material needed and dimensional and functional requirements pursued. Each technology offers different possibilities in terms of resolution, complexity, versatility, speed, layers thickness, materials, reliability and scalability. This work aims to dig deeper into two of the main techniques in the world of printed electronics: screen printing and inkjet printing for different applications and for the manufacturing of different devices. In addition, the capabilities of a technology that is currently in growing development (inkjet) are analyzed in comparison with the mature screen printing technique to give a wider insight of the advantages and limitations that this technology offers. The totally knowledge in this technique is still in progress and it arises to be a trend in technological and scientific aspects due to the barely availability of functional materialsii and the difficulties in achieving a precise control on the drop formation and its interaction in the final system. A better understanding of these technological issues, as well as the approaching to current difficulties in electronic applications is accomplished in this thesis. Up-to-date issues as the reliability of flexible resistive gas sensors, solution-based synthesis of absorber layers in thin film solar cells and the tuning and area reducing for inductors in RF applications are tackled. The main objective in this thesis arises from the need of expanding the knowledge on inkjet printing by exploring affordable new possibilities, taking as starting point the previous knowledge of screen printing. To pursue this goal, the comparison between SP and IP is presented along the thesis. The framework of this thesis is not solely an overview of the development of functional materials for both techniques, but also the investigation of its final implementation reliability in several devices for different electronic applications. The structure of this thesis dissertation can be divided in two well defined blocks. In chapter 2 and 3, both printing techniques are explained in detail, while in Chapter 4, 5 and 6, the potential of both technologies are studied for different electronic applications by means of the fabrication and characterization of different devices. In chapter 2, the main topic is the analysis of the inkjet printing technique. This chapter follows the attainment of two different objectives: the establishment of a quality evaluation guideline for any inkjet ink and as example of it, the formulation of our own silver ink developed in our laboratory. In this sense, the most important properties for the functional materials which should be under control during its formulation are reviewed; as well as the fundamentals and main parameters during the printing process, which affect the outcome quality. Instead, in chapter 3, the fundamentals of screen printing technique are quickly overviewed due to the consolidation of the technique knowledge and the previous studies on it done in the field, and specifically at FAE Company. In the second block of this thesis, the description of the printing techniques leads to the implementation of both, inkjet and screen printing, in different electronic fields. The chapters involving this block are focused in the printing step during its fabrication, the printing and functional material quality characterization, and the influence of this printing step in the functional performance of the devices. Chapter 4 is a comparison between low-cost flexible resistive sensor platforms with heater fabricated by both, SP and IP techniques. The performance of these sensor platforms was checked by long-term characterization and aging tests to identify the causes of the device failure. Chemical degradation of silver is observed in SP-devices due to the flake-like morphology of the deposits but not in the smooth sintered silver tracks deposited by IP. However, the IP very thin film promotes failure by hot spot phenomena. Design improvements are, hence, implemented to overcome the drawbacks of silver corrosion and power consumption. The final devices turned to be sturdy, wearable and reliable gas sensor platforms. In Chapter 5, IP is implemented in the step of the absorber layer synthesis for the fabrication of kesterite thin film solar cells. Copper-Zinc-Tin-Sulfur (CZTS) precursor ink is formulated and optimized for the enhancement of the solar cell performance. The influence of the formulation and the printing process is analyzed. Finally, the thickness of the deposited precursor was modified until obtained a cell with 6.55% efficiency, the higher efficiency reported with this absorber type using IP as deposition method. In the last chapter, Chapter 6, spiral inductors are fabricating using the two printing technologies in LTCC (low-temperature-cofired-ceramics). IP, although turning out to be a suitable technology for enhancing the accuracy of narrower tracks than SP and thus, for increasing the number of turns within a concrete area, presents difficulties to achieve a certain value in electrical conductivity due to the deposition of very thin conductor layers. For this reason, in this part of the thesis, a combination of IP with electroless copper deposition is used to overcome this limitation and to develop equivalent performances using SP and IP devices.

Download or read book Silk Screen Printing for Artists and Craftsmen written by Mathilda V. and James A. Schwalbach and published by Courier Corporation. This book was released on 2012-07-26 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Screen printing is simple enough for a child or beginner, but it is also a favorite printing process of experienced artists and craftspeople. It allows for a wide range of creative possibilities. It is less inhibiting than other printing processes. And, contrary to most other methods of printing, it does not require the user to make the mental translations of a reversed image. The extreme versatility of the medium has opened completely new possibilities for design and expression in both serigraphy (art prints) and textile designs. The Schwalbachs' book clearly explains how to employ silk-screen printing in both of these areas: producing a serigraph and making a fabric print. It also sets down all of the steps involved in constructing a printing board and frame, keying the screen, preparing inks or dyes, and printing the color runs — plus a list of various problems that might turn up and their solutions. Other facets discussed include the best ways of cleaning up, handling the completed print, and working with different resists — paper, blockout, washout, photo-emulsion. There is even a special print project for the beginner, using a cardboard frame and school tempera paint. Nearly 200 diagrams and photographs, including 19 in full color, make a clear text even clearer and offer examples of completed prints. The Schwalbachs taught silk-screen printing for many years at the University of Wisconsin. They know how to communicate the essence of this craft in the best manner possible. With their book as a guide, anyone can quickly master the techniques of silk-screening printing.
