Abstract
An electronic assembly includes 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 includes a first barrier layer including an atomic layer deposited film and a second barrier layer including Parylene.

A method comprising:
- forming, by atomic layer deposition, a first barrier layer on at least a portion of a surface of a printed circuit board (“PCB”) and on an outer surface of an electrical component attached to the surface of the PCB;
- and
- forming, on the first barrier layer, a second barrier layer comprising Parylene.
An imaging device comprising:
- a camera head;
- and
- a shaft that extends from the camera head and that comprises:
- a distal end configured to be positioned within a surgical area of a patient, and
- one or more channels within the shaft that are configured to provide signals to the camera head,
- wherein
- the camera head houses a printed circuit board (“PCB”) and electrical circuitry on the PCB, the electrical circuitry configured to
- receive the signals, and
- process the signals, and
- a conformal barrier is disposed on at least a portion of the PCB and on the electrical circuitry, the conformal barrier comprising an atomic layer deposited (“ALD”) film.
