Dual‑Tube Housing Multi‑Pin Sintered Hermetic Feed‑Through Base

This sintered hermetic feed-through base combines three structural features: a dual-tube housing, a multi-pin layout, and sintered sealing. Dual-tube housing means the housing is made of two tubular structures rather than a single tube, providing tubular enclosure at different positions. The multi-pin layout means the base contains several independent connection channels gathered into one base body. Sintered sealing means the base forms its seal through a glass-to-metal sintering process. Together, the base relies on the dual-tube housing for two tubular structures, provides multiple paths for connection, and uses sintering for sealing, which suits feedthrough positions that need two-tube enclosure, multiple connections, and sintered sealing. The dual-tube structure can accommodate different paths separately.

A structure combining a dual-tube housing with multiple pins places high demands on the relative position of the two tubes and on pin pitch consistency. The technical team has long been engaged in metal-glass sealing research and holds more than twenty independent intellectual property rights. For bases like this, the relative position of the two tubes and internal pin positions must stay consistent through sintering and assembly, so tooling and fixtures need to correspond to the specific specification. The company runs five metal-glass sealing production lines and has developed hundreds of product variants used in hybrid integrated circuits, relays, sealed connectors, and pressure sensors.
