Abstract
A method includes forming, by atomic layer deposition, a first barrier layer on a surface of a printed circuit board (“PCB”) and on an outer surface of an electrical component attached to the surface of the PCB; forming an adhesion promotion layer on a surface of the first barrier layer; and forming, on the adhesion promotion layer, a second barrier layer including Parylene.
Claims20
A method comprising:
- forming, by atomic layer deposition, a first barrier layer on a surface of a printed circuit board (“PCB”) and on an outer surface of an electrical component attached to the surface of the PCB;
- forming an adhesion promotion layer on a surface of the first barrier layer;
- and
- forming, on the adhesion promotion layer, a second barrier layer comprising Parylene.
1 more element
An electronic assembly comprising:
- a printed circuit board (“PCB”);
- an electrical component attached to a surface of the PCB;
- and
- a conformal barrier disposed on at least a portion of the surface of the PCB and on an outer surface of the electrical component, the conformal barrier comprising:
- a first barrier layer comprising an atomic layer deposited (“ALD”) film;
- and
- a second barrier layer comprising Parylene and coupled with the first barrier layer by way of an adhesion promotion layer.
