Micro LED / Micro Optics

Miniaturized optical components such as µLED are used in many areas, just think of medical technologies (brain implants, virtual retina displays), consumer electronics (smart watches, cellphone displays, pico beamers), and also automotive, avionics or defense.

A single µLED can be as small as 30 µm and often have sophisticated structures or shapes. And not only are the components tiny and fragile, additional challenges are presented with very thin Die Attach Foils (DAF) or solder preforms used to connect the assemblies.

Once the number of µLED in a product surpasses a critical amount, economic considerations require that the components are handled simultaneously in the form of µLED arrays instead of placing and bonding them one after the other. Also, this allows using µLED with even smaller dimensions which could no longer be handled safely as single components.
