| You're fundamentally wrong on this. What you are talking about is true only for inductive coupling caused by fluctuating EM waves. As someone who works in Embedded Electronics and Software for Aerosopace let me drop a little knowledge bomb. The problem isn't with induction, all the units can be easily shielded from this and they are in EMC chambers every day. A simply faraday cage, some bypass and reservoir capacitors a choke here and there an opto-isolator on box boundaries and bobs your uncle. The real problem with High Energy Particles (Neutrons, Gamma particles, Protons, etc) is that they displace atoms in your semiconductor lattice and change the doping densities and behaviours of your junctions. Causing your semiconductor to fail... HARD. When we buy in components, we tend to buy rad-hard devices which have special considerations taken into account when designing the semiconductors because when you're in space, you're bombarded with LOADS of high energy particles all the time, and its not just enough to have memory TMR, you need RAD-HARDENED semiconductors. |
