| Abstract Scope |
Low earth orbit (LEO) electronic systems are a necessity for GPS, weather prediction, and telecommunications. However, space is a harsh environment with radiation capable of causing operation issues and degradation of the entire system. Circuit board scale shielding schemes of electronics against radiation add cost, size, weight, and complexity. We propose an alternative approach which focuses on component-based selective radiation shielding also referred to as “spot shielding”. Aerosol jet printing can deposit a wide range of radiation shielding nanocomposite materials on microelectronic components with high precision and resolution. Polyimide (PI) inks containing different loadings of hexagonal boron nitride (h-BN) nanoparticles were formulated and printed using aerosol jet printing. The inks consisted of PI, PI-25 wt% h-BN, PI-50 wt% h-BN, PI-75 wt% h-BN, and h-BN. The printed thin films were characterized by Fourier-transform infrared spectroscopy (FTIR) before and after exposure to gamma radiation at a dosage of 80 krad (Si). |
