Access to Infrastructure
Providing access to lab infrastructure is one of CITC’s key capabilities.
The lab is one of the key capabilities of CITC and is a key differentiator for our customers. It facilitates our innovation programs and also supports the education programs through internships and MSc/PhD programs. Additionally the lab serves as demo and application lab for new types of equipment and materials. CITC has a Smart Industry Field Lab status, indicating that it is a place where industry and research organizations jointly develop, test and implement smart industry solutions.
In addition to our own lab facilities, CITC has access to lab facilities of our strategic partners TNO and TUD. This includes for instance the facilities of TNO Holst in Eindhoven and the Else Kooi Lab (EKL) of the TUD in Delft.
The lab has all the equipment and tooling for basic packaging assembly technologies. Among others we can do high precision dispensing (glue, solder paste), automated die pick up and die attach, wirebonding and temperature profile curing. The equipment in the lab is selected such that it can be used for investigating the physical aspects of several assembly processes. We have the capabilities to do fast prototyping for proof of principle samples. Next to this, our lab is equipped with sample preparation technologies like plasma cleaning. We also have the equipment to test and evaluate the quality of the assembly process.
