Use case: Digital Twin of Industrial Wire Bonder Machine
Strengthening the competitive edge in the market of the assembly and packaging equipment for electronics manufacturing, digitalization and virtualization is of increasingly importance at ASM Pacific Technology LTD. Especially digital twins of the ASM products are getting particular attention, because of their values in all phases of equipment development, production and operational use.
In this project, we develop digital twins of an industrial wire bonder machine, which makes wired interconnections between the semiconductor die and its packaging. These interconnections are created by rapid machine movements at high speeds and accelerations, with sub-micrometer precision. A digital twin of a wire bonder should capture machine dynamics that have critical influence on accuracy of the machine motions during wire bonding. Furthermore, model updating algorithms will be developed for automated and time-efficient calibration of the model parameters
(e.g. stiffness and damping coefficients). We also aim to incorporate multi-physics models into the digital twin, by modelling thermally induced mechanical deformations of the machine parts that affect precision of the wire bonding.
The resulting digital twin will help us:
- Understand root-causes of the critical machine dynamics
- Compensate for position errors caused by structural and thermal deformations
- Optimize machine design
- On-the-fly machine health monitoring and fault isolation
