Flexible type electrical feed-through connector assembly

An electrical feed-through configured to interface between a hermetically-sealed environment and an external environment, the feed-through comprising:

• a flexible printed circuit (FPC) part comprising a base insulating layer, a conductor layer over the insulating layer, and a cover insulating layer over the conductor layer, wherein the conductor layer comprises a plurality of electrical connection pads and electrical conductors connecting pairs of the pads;
• a metal plate at least in part around which the FPC is wrapped and to which the FPC is adhered, forming a connector assembly comprising first pads of the pairs on an upper side of the connector assembly electrically connected via the conductors to second pads of the pairs on the lower side of the connector assembly;
• a first board-to-component connector part electrically connected to a first set of the first pads;
• a second board-to-component connector part electrically connected to a second set of the first pads;
• and
• a third board-to-board (BTB) connector part electrically connected to the second pads.

A method of manufacturing an electrical feed-through component, the method comprising:

• forming a laminate flexible cable assembly (FCA) comprising a base insulating layer, a conductor layer over the insulating layer, and a cover insulating layer over the conductor layer, wherein the conductor layer comprises a plurality of electrical connection pads and electrical conductors connecting pairs of the pads;
• folding the FCA at least in part around a metal plate;
• adhering the FCA to the metal plate, forming a connector assembly comprising a first set and a second set of first pads of the pairs on an upper side of the connector assembly electrically connected via the conductors to second pads of the pairs on the lower side of the connector assembly;
• electrically connecting a first board-to-component connector part to the first set of first pads;
• electrically connecting a second board-to-component connector part to the second set of first pads;
• and
• electrically connecting a board-to-board (BTB) connector part to the second pads.

A method of sealing an interface between a hermetically-sealed environment of an electronic component and an external environment, the method comprising:

• providing electrical transmission means for transmitting electrical signals through the interface;
• providing first electrical connection means between a first portion of the electrical transmission means located in the hermetically-sealed environment and a component located in the hermetically-sealed environment;
• providing second electrical connection means between a second portion of the electrical transmission means located in the hermetically-sealed environment and a component located in the hermetically-sealed environment;
• providing electrical connection means between a portion of the electrical transmission means located in the external environment and a component located in the external environment;
• and
• providing hermetically-sealing means for bonding the electrical transmission means with an enclosure base of the electronic component.
