Abstract
A device includes a printed circuit board assembly having a printed circuit board and one or more electronic components disposed on the printed circuit board, and a nanofilm disposed on the printed circuit board assembly. The nanofilm includes an inner coating in contact with the printed circuit board assembly, the inner coating including metal oxide nanoparticles having a particle diameter in a range of 5 nm to 100 nm; and an outer coating in contact with the inner coating, the outer coating including silicon dioxide nanoparticles having a particle diameter in a range of 0.1 nm to 10 nm.
Claims22
A device, comprising:
- a printed circuit board assembly including:
- a printed circuit board;
- and
- one or more electronic components disposed on the printed circuit board;
- and
- a nanofilm disposed on the printed circuit board assembly, the nanofilm including:
- an inner coating in contact with the printed circuit board assembly, the inner coating including metal oxide nanoparticles having a particle diameter in a range of 5 nm to 100 nm;
- and
- an outer coating in contact with the inner coating, the outer coating including silicon dioxide nanoparticles having a particle diameter in a range of 0.1 nm to 10 nm.
A method for forming a device, comprising:
- applying a first solution to an object, the first solution including metal oxide nanoparticles and a first solvent;
