Fully encapsulated electronics and printed circuit boards

A method of encapsulating and hermetically sealing electronic components of a flex cable assembly and integrating the flex cable assembly into a surgical device, comprising:

• positioning a printed circuit board portion of a flex cable assembly into a channel defined in a first housing half of an encapsulation housing, the printed circuit board portion including a substrate of a first flex cable of the flex cable assembly and electronic components mounted on the substrate;
• mounting a second housing half onto the first housing half to enclose the channel of the first housing half and form a cavity within the encapsulation housing;
• and
• filling the cavity of the encapsulation housing with an encapsulation material through an inlet opening defined through the encapsulation housing.
