The main aim of the Assembly and Packaging Laboratory is the development of back-end and packaging technologies for components in the field of photonics, optoelectronics, mems, moems, sensors and LED/OLED that can apply in the investigation, prototipation and packaging engineering in areas as telecom, datacom, biotecnology, ambient, microelectronics and space applications. Furthermore, we are also focused on package design utilizing softwares including optical, thermal and mechanical simulations (AutoCad, Comsol, Zemax).

General packaging process once a silicon photonic wafer has been manufactured.
