1. 1. Improving jet printing quality for printed circuit boards : Optimizing first dot jetting deposition through experimental design and response surface methodology

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :William Hedlund; Gustav Sjöberg; [2023]
   Nyckelord :PCB; printed circuit board; piezo-actuation profile; quality; My700; solder paste; jet printer; jet printing; experimental design; experimental approach; waveform;

   Sammanfattning : Printed circuit boards (PCBs) are essential components in various electronic devices, playing a vital role in their functionality. Over time, PCBs have evolved significantly, becoming smaller, more complex, and multi-layered to meet the demands of advancing technology and consumer preferences. LÄS MER

3. 2. Jet Printing Quality ImprovementThrough Anomaly Detection UsingMachine Learning

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Henrik Lind; Jacob Janssen; [2021]
   Nyckelord :Jet Printing; Autoencoder; Anomaly Detection; Sound; Acoustic; Machine Learning; Solder Paste; Piezoelectric Current; Self Sensing;

   Sammanfattning : This case study examined emitted sound and actuated piezoelectric current in a solderpaste jet printing machine to conclude whether quality degradation could be detected with an autoencoder machine learning model. An autoencoder was used to detect anomalies in non-realtime that were defined asa diameter drift with an averaging window from a target diameter. LÄS MER

4. 3. Parameter Tuning in a Jet Printing Machine usingReinforcement Learning

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :ALEXANDER MURTAZA; [2021]
   Nyckelord :Jet printer; Reinforcement Learning; Q-learning; Parameter tuning; Surface mount technology; Jet printer; Förstärkande inlärning; Q-learning; Parameter justering; Ytmontering;

   Sammanfattning : Surface mount technology is a common way to assembly electrical components onto PrintedCircuit Boards (PCB). To assemble the components, solder paste is used. One way to apply solderpaste onto PCB is jet printing. LÄS MER

5. 4. Quality Prediction in Jet Printing Using Neural Networks

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Daniel Brun; Colin Lawless; [2020]
   Nyckelord :;

   Sammanfattning : Surface mount   technology   is   widely   used   in   the   manufacturing   of   commercial  electronics, and  the  demands  on  the  machines  increase  as  the  complexity of  the electronics increases and the size of the components decreases. Mycronic is a company that focuses on addressing those demands with their high-technology jet printing and pick-and-place machines. LÄS MER
