Internship | Laser-Assisted High-throughput Micro-component Assembly

With the growing demand for ever-smaller devices, such as mini- and microLED displays with higher resolution rates, there is an unstoppable trend towards miniaturisation of components. High-speed, mass-production of these electronics is getting more and more difficult, because the handling and accurate placement of these tiny components is very challenging. Each component needs to be carefully selected, transferred and then accurately placed and assembled with interconnects – all at lightning speeds.

As you can imagine, a lot of things need to fall into place in order to make this happen. One important piece of this puzzle is the placement of the die attach material, which will make both a physical and electrical connection of the component to the substrate.

At Holst Centre we developed a laser based technology which is capable of printing ultra-fine dots of die-attach material. For this technology an embossed transparent carrier mask (see figure below) is filled with the die attach material, which is then transferred using a single laser pulse. A crucial part of this is the correct and reproducible filling of the carrier mask. In order to optimize this filling process, an automatic coating setup has been designed and built. The goal of this internship is to use the automatic coating setup to optimize the filling parameters and then based on the findings to oversee the design and building of a dedicated filling tool for further development of the process.

As a team member your tasks will be:

1. Knowledge acquisition through literature survey and discussion with other team members;
2. Performing experiments in clean-room labs;
3. Analysis of the experimental data and presentation thereof;
4. Documenting results in a technical report and taking part in technical meetings, internal seminars/colloquiums.

For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
  • you are enrolled at the educational institution during the internship, and;
  • the internship takes place as part of the programme of the study.
• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
