Internship Laser-Assisted High

About this position

One of the key expertise areas of TNO/Holst Centre is Laser-Assisted High-throughput Microcomponent 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 conventional industrial equipment fail to deposit ultrafine pattens of die attach material and handle such tiny components at required high rates, this calls for development of alternative high-throughput assembly technologies.

What will be your role?

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.
