Abstract:
A conformal coating comprising modified porous silica particles is disclosed. A porous silica particle, such as MCM-14 or SBA-15 is modified with a sulfur gettering functionality, such as a phosphine compound, covalently bonded to silicon atoms in the porous silica particle. The conformal coating comprising the modified porous silica particles may be applied to metallic wiring areas of a circuit component, with the sulfur gettering functionality preventing sulfur from atmospheric gasses from penetrating the conformal coating to the metallic wiring.
Abstract:
A moisture-resistant electronic device includes at least one electronic component at least partially covered by a moisture-resistant coating. The moisture-resistant coating may be located within an interior of the electronic device. The moisture-resistant coating may cover only portions of a boundary of an internal space within the electronic device. A moisture-resistant-coating may include one or more discernible boundaries, or seams, which may be located at or adjacent to locations where two or more components of the electronic device interface with each other. Assembly methods are also disclosed.
Abstract:
An electronic component packaging structure includes a circuit board, electronic components mounted on the circuit board and a moisture-proof coating layer covering the electronic components. The moisture-proof coating layer is constituted from a polymer material coating having at least two layers of a lower layer and an upper layer, and the polymer material forming the lower layer has higher swelling property and/or solubility to a repairing solvent that is selected from among hydrocarbon-based solvents than the polymer material forming the upper layer.
Abstract:
A method of forming a film is provided. Nanoparticles are deposited on a surface of a substrate using a liquid deposition process. The nanoparticles are linked to each other and to the surface using linker molecules. A coating having a surface energy of less than 70 dyne/cm is deposited over the film to form a coated film. The coated film has an RMS surface roughness of 25 nm to 500 nm, a film coverage of 25% to 60%, a surface energy of less than 70 dyne/cm; and a durability of 10 to 5000 microNewtons. Depending on the particular environment in which the film is to be used, a durability of 10 to 500 microNewtons may be preferred. A film thickness 3 to 100 times the RMS surface roughness of the film is preferred.

Abstract:
A system and method for providing shielding to an electrical system is disclosed. A conformal shield is formed by applying a conformal insulating coating to an electrical system. A plurality of openings are formed in the insulating coating at desired locations and a first metallic layer is deposited over the insulating coating and in each of the plurality of openings, the first metallic layer being electrically connected with the circuit board at the desired locations. A second metallic layer is then deposited onto the first metallic layer to increase a thickness of the metallic layers.
Abstract:
An electronic circuit component is provided with shielding for electromagnetic interference (“EMI”) by covering at least part of the component with a layer of electrical insulation that conforms to the shape of the surface to which the insulation is applied. At least part of the surface of the insulation is then covered by a layer of EMI shielding that conforms to the shape of the surface of the insulation to which the shielding is applied.
