HERMETICALLY SEALED ELECTRONIC PACKAGES WITH ELECTRICALLY POWERED MULTI-PIN ELECTRICAL FEEDTHROUGHS
A hermetically sealed electronic package may include a thermal panel having a panel interior surface and a panel exterior surface with electronic device(s) in thermal communication with the panel interior surface. An enclosure, isolating environmental communication from internal electronic devices and modules, may be coupled to the thermal panel, and the enclosure may have an enclosure interior surface and an enclosure exterior surface. A plurality of electrical feedthroughs may be coupled to the package enclosure for signal and data transmission, and the conducting pin(s) in every electrical feedthrough may be bonded by a hydrophobic sealing material for harsh environmental electrical signal, data and power transmission. The ratio of sealing length over sealing bead diameter in the electrical feedthrough subassembly may have a preferred value from 2 to 3; and the ratio of the sealing bead diameter over pin diameter in the electrical feedthrough subassembly may have a preferred value from 1.5 to 2.0, where a preferred thermal stress resistance could be designed for making highly hermetic sealed electronic package.
Sealing interface for a telecommunications enclosure
A sealing interface (26) that utilizes an elastomeric sealing member (28) is disclosed herein. The sealing interface (26) is configured to provide effective sealing while requiring only relatively low amounts of force to deform the elastomeric sealing member (28) sufficiently to form an effective seal.
Flat-through capacitor mounted in a tombstone position on a hermetic feedthrough for an active implantable medical device
A three-terminal flat-through EMI/energy dissipating filter comprises an active electrode plate through which a circuit current passes between a first terminal and a second terminal, a first shield plate on a first side of the active electrode plate, and second shield plate on a second side of the active electrode plate opposite the first shield plate. The first and second shield plates are conductively coupled to a grounded third terminal. Both the effective capacitance area or overlapping surface area of the active electrode plate and the surrounding ground shield plates and the dielectric constant of the insulating layers between the active electrode plate and the ground shield plates is raised to achieve a higher capacitance value for the three-terminal flat-through capacitor.
Ground electrical path from an MLCC filter capacitor on an AIMD circuit board to the ferrule of a hermetic feedthrough
An EMI/energy dissipating filter for an active implantable medical device (AIMD) is described. The filter comprises a first gold braze hermetically sealing the insulator to a ferrule that is configured to be mounted in an opening in a housing for the AIMD. A lead wire is hermetically sealed in a passageway through the insulator by a second gold braze. A circuit board substrate is disposed adjacent the insulator. A two-terminal chip capacitor disposed adjacent to the circuit board has an active end metallization that is electrically connected to the active electrode plates and a ground end metallization that is electrically connected to the at least one ground electrode plates of the chip capacitor. There is a ground path electrically extending between the ground end metallization of the chip capacitor and the ferrule. The ground path comprises at least a first electrical connection material connected directly to the first gold braze, and at least an internal ground plate disposed within the circuit board substrate with the internal ground plate being electrically connected to both the first electrical connection material and the ground end metallization of the chip capacitor. An active path electrically extends between the active end metallization of the chip capacitor and the lead wire.
