| Abstract Scope |
Space-based systems are a necessity for GPS, weather prediction, and communication. However, space is a harsh environment with radiation capable of causing software issues and degradation of electrical components. Package shielding of electronic components against radiation can add cost, size, weight, and complexity to these systems. An alternative is to spot shield susceptible electronic components where needed. Aerosol jet printing can deposit a wide range of radiation shielding nanocomposite material on microelectronics with high precision and resolution. Polyimide (PI) inks containing different loadings of hexagonal boron nitride (h-BN) nanoparticles were formulated and printed using pneumatic atomization 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 before and after exposure to gamma radiation. |
