| Summary: | There is a growing need for ever more complex electronic systems as manufacturers aim to increase the functionality of their manufactured components. Direct write manufacturing is a technology that can provide a means to multi-functional components providing enhanced integration and automation in the manufacture of electronic systems An inkjet deposition system was used to fabricate electrical interconnects using dielectric and silver nanoparticie inks. To prevent thermal damage to the underlying substrate these inks were functionalised using localised post-process methods instead of conventional oven process routes. To improve on the electrical conduction of the printed components a localised electroplating system was devised. Durability of the printed components is essential to all applications. The inks were tailored to improve the robustness and were found to have passed preliminary aerospace durability and environmental testing. This direct write system was used to fabricate direct write electronics on an aerospace helmet shell. This was a proof-of-concept demonstrator and successfully shows that conformal electronic interconnects can be fabricated onto existing components. |
