Abstract
A method of assembling a hermetically sealed printed circuit board includes: securing a first end portion of a wall of a cap to a substrate around an electrical contact region of the substrate, the wall including a second end portion disposed in an open configuration; mounting an electronic component to the electrical contact region of the substrate; and sealing the second end portion of the wall closed to form a hermetically sealed chamber between the substrate and the cap to encase the electronic component therein.
Claims16
A hermetic electronics assembly comprising:
- a printed circuit board including a plurality of electronic components disposed on a first side thereof, the plurality of electronic components offset a distance from outer edges of the printed circuit board;
- and
- a cap including a wall having a first end portion and a second end portion, the first end portion including a flange welded to the printed circuit board entirely around the plurality of electronic components and the second end portion heat sealed closed a distance spaced from the plurality of electronic components,
- wherein the welding of the first end portion to the printed circuit board and the heat sealing of the second portion of the wall together form a hermetic seal encasing the plurality of electronic components therein.
A method of assembling a hermetically sealed printed circuit board, the method comprising:
- securing a first end portion of a wall of a cap to a substrate around an electrical contact region of the substrate by welding a flange of the first end portion of the wall of the cap to the substrate to bond the first end portion of the wall of the cap to the substrate, the wall including a second end portion disposed in an open configuration;
- mounting an electronic component to the electrical contact region of the substrate;
- and
- sealing the second end portion of the wall closed to form a hermetically sealed chamber between the substrate and the cap to encase the electronic component therein.
A method of assembling a flex cable and integrating the flex cable into a surgical device, the method comprising:
- assembling electronic components on a first side of a substrate of a flex cable within a perimeter of a wall secured to the substrate, the wall extending transversely from the first side of the substrate and terminating at an open end;
- closing the open end of the wall such that the electronic components are disposed within a sealed chamber;
- placing the flex cable into an adapter assembly of the surgical device;
- and
- electrically connecting the flex cable with a handle assembly and with an end effector of the surgical device to enable communication between the handle assembly, the adapter assembly, and the end effector.
