Assembly and Packaging Technology

Assembly and packaging comprises a complex technology which aims at the fabrication of electronic hardware. This technology is mainly based on Materials Science and Engineering, Mechanical and Electrical Engineering. The target is to connect a functional element to an application and at the same time to protect it from the environment. Fabrication technologies comprise assembly, joining and interconnection, while the main constructional elements are substrates, housings or packages. For all of these present days' state of the art is presented and the fundamental requirements are demonstrated. So the students will get an overview of the basic manufacturing operations and the required materials in order to integrate electronic hardware. Besides, it is indispensable that knowledge about modern techniques for design optimization will be taught. Electronic systems must fulfill specifications concerning integration density, high frequency behaviour, thermal management, thermal-mechanical behavior and lifetime. To that purpose, the basic techniques for performance and reliability optimization will be regarded. In this way, it is desired that the students will become capable of finding own solutions in the field of assembly and packaging of microsystems. The course comprises the following’s: 

  1. Housing and packaging technologies Hermetic and plastic packaging, wafer-level packaging
  2. Substrates Printed circuit boards, multi-chip-modules, molded interconnect devices
  3. Assembly technologies Surface mount technology, adhesive bonding
  4. Interconnection technology Wire bonding, flip-chip-bonding
  5. Electromagnetic compatibility EMC Integrity and speed of electrical signals and equivalent circuits
  6. Thermal management Temperature problems and cooling techniques
  7. Mechanical optimization Stress-affected problems, solder joint reliability

Polymer Processing and Microsystems Engineering

Polymers are ubiquitous in the 21st century. As a material class, polymers have seen an astonishing gain in academic and industrial significance since their first introduction into the market more than 140 years ago. One of the most striking advantages of polymers is their ease of processing in which they outperform almost any other material known to humankind.

This lecture introduces the fundamentals of polymer processing focusing on techniques such as injection molding, hot embossing, thermoforming and nanoimprinting. These techniques represent the most important reforming processes. We will also explore additive manufacturing and 3D Printing including stereo lithography, powder-based as well as inkjet printing and fused deposition modeling.

The didactic concept underlying the lecture is built on a combination of material science and instrumentation development and thus represents a holistic view onto the broad field of technical polymer processing.

Polymers in MEMS A: Chemistry, Synthesis and Applications

We all come in contact with numerous polymeric products in everyday life. From water bottles to packaging to the cover of the iPad, many things are made of polymers. Polymers are also important materials for modern microelectromechanical systems (MEMS) allowing cost effective mass market compatible products, e.g., in the life sciences or diagnostics. But polymers are not just cost-effective replacements for more expensive classical materials in MEMS (such as, e.g., silicon) – some polymers have intrinsic properties that make them ideal materials for sensors, actuators or templates for biology and chemistry in MEMS.

This lecture will introduce the basics of organic chemistry required for understanding what polymers are, how they are manufactured and which mechanisms are responsible for their unique properties. The lecture will highlight (in the context of MEMS but also in a wider scope) where and why polymers are applied with a strong focus on their chemical and physical properties (and on their synthesis).

Modalities of the course

The course is an online self-taught course, i.e., you can study the lecture material using the presented material at your own leisure and pace. If you have questions, please PM the teacher or write a message to the forum - the teacher will be informed about new messages posted daily.

Polymers in MEMS B: Physics, Manufacturing and Applications

This lecture will introduce the basics of physics and material science required for the understanding of the mechanical behavior seen from the engineers view. Micro and nanostructuring of polymers allows the fabrication of micro parts fulfilling their tasks in mostly invisible different applications. But also the fabrication of polymer parts with functional surfaces inspired from Bionics will be presented in this lesson. The lesson will give further an overview over the polymer based structuring processes and will underline the importance by a number of applications e.g. photonic structures or Lotus-like structures.

For further details, please contact the lecturer, PD Dr.-Ing. Matthias Worgull (matthias worgull∂kit edu). Preregistration is not necessary.

Polymers in MEMS C - Biopolymers and Bioplastics

Polymers are ubiquitous in everyday life: from packaging materials all the way to specialty products in medicine and medical engineering. Today it is difficult to find a product which does not (at least in parts) consist of polymeric materials. The question of how these materials can be improved with respect to their disposal and consumption of (natural) resources during manufacturing is often raised. Today polymers must be fully recycled in Germany and many other countries due to the fact that they do not (or only very slowly) decompose in nature. Furthermore significant reductions of crude oil consumption during synthesis are of increasing importance in order to improve the sustainability of this class of materials. With respect to disposal polymers which do not have to be disposed by combustion but rather allow natural decomposition (composting) are of increasing interest. Polymers from renewable sources are also of interest for modern microelectromechanical systems (MEMS) especially if the systems designed are intended as single-use products.

This lecture will introduce the most important classes of these so-called biopolymers and bioplastics. It will also discuss and highlight polymers which are created from naturally created analogues (e.g. via fermentation) to petrochemical polymer precursors and describe their technical processing. Numerous examples from MEMS as well as everyday life will be given.
