Delo - Adhesives for electrical and mechanical connection for mini- and microLEDs in fine pitch applications

This presentation highlights the importance of reducing the weight of semiconductor assemblies to improve the efficiency of electric vehicles and the acceptance of wearables like smart glasses. The use of functional polymers is essential for optimizing specific properties based on customer requirements. The development of a generic test board has allowed for the evaluation of mechanical and electrical characteristics of miniLED chips, both individually and in series. The adhesive benchmarking measured values such as die-shear and connection resistance, which were then statistically evaluated. The results of this evaluation will be discussed in terms of the possibilities for optimizing material composition and process properties. Ultimately, the presentation emphasizes that functional polymers, particularly adhesives, have the potential to greatly contribute to the market launch of next generation mini microLED devices.
