Patent ID: 8148830

Claim:
A circuit board assembly comprising: a circuit board having an outer surface, the outer surface being configured with a plurality of discrete electrical components that are each manufactured independently of one another; a first protective dielectric layer overlying the outer surface; a second dielectric layer overlying the first protective dielectric layer and the plurality of discrete electrical components, the second dielectric layer comprising a dielectric material having modulus of elasticity less than 3.5 Giga-Pascal (GPa), a dielectric constant less than 3.0, a dielectric loss less than 0.008, a moisture absorption less than 0.04 percent, a breakdown voltage strength in excess of 2 million volts/centimeter (MV/cm), a temperature stability to 300° Celsius, pinhole free in films greater than 50 Angstroms, hydrophobic with a wetting angle greater than 45 degrees, capable of being deposited conformally over and under 3D structures with thickness uniformity less than or equal to 30%; and an additional protective dielectric layer between the first protective dielectric layer and the second dielectric layer, the additional protective dielectric layer having a thickness in the range of approximately 50 to 2000 angstroms, wherein the additional protective dielectric layer is a nanolaminate comprising alternate combinations of nanolaminate material that is selected from the group consisting of alumina, tantalum oxide, beryllium oxide, hafnium oxide, silicon-dioxide, fluorinated parylene, acrylic, and vapor deposited Teflon (PTFE).
