Sintering of Metal Nanoparticles by Local Induction Heating and Evaluation of Their Properties

Key Points

• This research aims to optimize induction heating systems for effective sintering of metal nanoparticles.
• Developed an induction heating system with self-optimizing resonant frequency for efficient heating.
• Evaluated heating performance using metal samples and monitored resonant frequency adjustments during heating.
• Attempted direct sintering of conductive silver paste using heat and assessed the outcomes.
• Induction heating maintained stable temperatures by adjusting the resonant frequency during the heating process.
• Direct sintering of silver paste failed to achieve conductivity due to low eddy current heating.
• Localized heating with a soldering iron enabled effective sintering in a shorter duration, showing promise for future applications.
