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
An electronic assembly comprising:
- a printed circuit board (“PCB”);
- an electrical component attached to a surface of the PCB and included in an electrical circuit configured to process data based on signals received from a surgical component configured to be positioned within a surgical area associated with a patient;
- 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 an outermost barrier layer comprising an atomic layer deposited (“ALD”) film.

A method comprising:
- pre-cleaning a surface of a printed circuit board (“PCB”) with a plasma surface treatment;
- and
- forming, by atomic layer deposition, an outermost barrier layer on the surface of the PCB pre-cleaned with the plasma surface treatment and on an outer surface of an electrical component attached to the surface of the PCB.
A method comprising:
- forming an inner 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, wherein the inner barrier layer comprises Parylene;
- and
- forming, on the inner barrier layer by atomic layer deposition, an outermost barrier layer.
