1. 1. Towards Unconventional Applications of Wire Bonding

   Författare :Stephan Schröder; Frank Niklaus; Michael Mayer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro-electromechanical systems MEMS ; heterogeneous 3D integration; wire bonding; wire integration; transfer wafer bonding; nondispersive infrared gas sensing; low-stress packaging; shape memory alloy SMA ; infrared IR emitter; through silicon via TSV ; ethanol sensing; nitric oxide gas sensing; wafer-level; chip-level; Kanthal; nickel chromium NiCr ; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : This thesis presents novel heterogeneous integration approaches of wire materials to fabricated and package MEMS devices by exploring unconventional applications of wire bonding technology. Wire bonding, traditionally endemic in the realm of device packaging to establish electrical die-to-package interconnections, is an attractive back-end technology, offering promising features, such as high throughput, flexibility and placement accuracy.

3. 2. Have you heard about wire? Monitoring of the wire drawing process

   Författare :Joakim Larsson; Christer Korin; Anton Jansson; Patrik Karlsson; Rachel Pettersson; Diana Janis; Örebro universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wire drawing; process monitoring; condition monitoring; drawing force; performance monitoring;

   Sammanfattning : Wire made from metal is a fundamental component found in almost every complex product, ranging from a simple pen to a spacecraft. It is used to manufacture nails, screws, springs, rivets, cables, welding electrodes, and numerous other items that surround us daily. LÄS MER

4. 3. The interdependence of plastic behaviour and final properties of steel wire, analysed by the finite element method

   Författare :Henrik Överstam; Magnus Jarl; Sven-Erik Lundberg; Chunhui Luo; Örebro universitet; []
   Nyckelord :Technology; FEM; defects; steel wire; wire drawing; rolling; forging; Teknikvetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Maskinteknik; Mechanical Engineering;

   Sammanfattning : The finite element method (FEM) has been used in order to study the interdependence of plastic behaviour and final properties in steel wire. Three processes metal forming have been studied: billet forging, wire rod rolling, and cold drawing. LÄS MER

5. 4. Roll pass design for improved flexibility and quality in wire rod rolling

   Författare :Conny Eriksson; Ulf Ståhlberg; Magnus Jarl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; wire rod; roll pass design; working range; productivity; swedish wire rod mills; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : The thesis treats roll pass design in wire rod rolling of stainless steel for sequences and series built up by two-symmetrical grooves. It is focused on predicting rolling flexibility, also called working range, as well as product quality. For analysing the flexibility a computer program has been developed. LÄS MER

7. 5. Sustainable Management of Wire-based Infrastructure : On the Multifaceted Challenges of Infrastructure Management in the Swedish Context

   Författare :Eman Hegazy; Stefan Anderberg; Joakim Johansson; Per Hillbur; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Infrastructure management; Maintenance and renewal; Sweden; Wire-based infrastructure;

   Sammanfattning : Cities, as key players in global sustainable development, are linked to challenges and opportunities driven by urbanization's resource consumption and environmental impacts. This context highlights the critical role of urban infrastructure in fostering sustainability, particularly the role of wire-based infrastructure systems (WBIS). LÄS MER
