Access to Infrastructure
CITC’s lab facilities support the innovation programs and contribute to education through internships and MSc/PhD programs. Our lab also serves as demo and application lab for new types of equipment and materials. It is also available to third parties to enable them to develop, test and implement new packaging solutions.
In-house facilities
Our lab has all the equipment and tooling for basic packaging assembly technologies:
- Surface (plasma) cleaning/sample preparation
- Dispensing/glue-solder depositing: dispensing, dam and fill, potting
- Die bonding: glue-solder-sinter
- Wire bonding: wedge-wedge, ball-wedge, Cu, Al
- Optical assembly: active, passive
- Testing: thermal, cross-sectioning, x-ray
CITC has a Smart Industry Field Lab status, which indicates that it is a place where industry and research organizations jointly develop, test and implement smart industry solutions.
Additional external facilities
Besides our own lab facilities, we have access to the lab facilities of our strategic partners TNO and Delft University of Technology (TUD), primarily for wafer-level processes.
This includes the facilities of TNO Holst Centre in Eindhoven and the Else Kooi Lab of TUD.
Assembly processes and technical capabilities
The equipment in our lab allows us to examine the physical aspects of various processes, with the ability to perform fast prototyping for proof-of-principle samples using industrial quality samples. We also have the equipment to test and evaluate the quality of the assembly process.
