Abstract
Conformal coatings provide environmental protection for sensitive military electronics. Preliminary MCNP™ modeling of metal oxide impregnated acrylic conformal coatings indicates an effective shield for gammas below 10 keV and a reduction in neutron displacement damage to Si-based electronics across the Watt spectrum. This work provides data which can allow an optimal overall shielding worth per total weight to eventually be evaluated.
Claims25
A method for shielding an electronic device for resistance to nuclear particle and photonic radiation, the method comprising:
- mixing a metal oxide with an acrylic resin to form a metal-oxide, acrylic resin composite;
- applying the metal-oxide, acrylic resin composite to surround an electronic device and form a conformal coating that encapsulates the electronic device and shields the electronic device from nuclear particle and photonic radiation;
- and
- curing the metal-oxide, acrylic resin composite to harden the conformal coating that encapsulates the electronic device.
A nuclear and photonic radiation resistant electronic device comprising:
- a semiconductor device;
- and
- a conformal coating that surrounds the semiconductor device and comprises a composite of a metal oxide and an acrylic resin for shielding the semiconductor device from nuclear particle and photonic radiation.
