Research Projects
Copper wire bonding mechanism and finite element analysis (FEA) on wire bonding process
This project is to improve the wire bonding reliability, study bonding mechanism, develop and optimize bonding process by using both experimental (SEM, TEM, ESCA, etc.) and numerical (eg. using FEA) analysis with Cu wire and/or Cu substrate/metallization.
Research Interests
- Microjoining technology in microelectronic packaging and assembly
- Laser soldering and lead-free soldering
- Ultrasonic wire bonding
- Finite element analysis by MARC.MSC, ANSYS and ABAQUS
