Junkosha Debuts 1mm Cable for Chip Equipment
The new cable aims to help vendors fit moving parts into tighter vacuum chambers.
Updated on Oct. 15, 2026 in Semiconductors
Engineers and equipment vendors in San Francisco's tech sector now have a new option for high-vacuum chamber components following the latest product reveal at Semicon West 2026. Junkosha has debuted a 1 millimeter pitch cable designed to fit into increasingly constrained semiconductor machinery.
Why it matters
As chip equipment designs prioritize smaller, more efficient vacuum chambers, manufacturers face constant pressure to integrate hardware without overhaul. This new cable aims to bridge that gap by offering a narrower construction that meets strict outgassing requirements for moving parts.
The new cable features a 1 millimeter pitch configuration and a tested lifespan of 30 million cycles at a 70 mm bending radius. Specific product launch pricing and market availability timelines remain unknown.
The players
Junkosha
An industrial technology manufacturer that develops specialized cabling for semiconductor equipment.
Semicon West 2026
The annual trade show and industry gathering where semiconductor manufacturers and equipment vendors present new hardware.
The details
Junkosha engineered this addition to its Super Low Outgassing Cable portfolio specifically for high-vacuum environments where space is at a premium. The company conducted testing in collaboration with semiconductor equipment vendors to ensure the cable maintains durability during the repeated, high-frequency motions required by modern fabrication tools. By minimizing the cable diameter, the design allows vendors to upgrade machinery performance while limiting the need for broader equipment redesigns.
Timeline
October 2026: Semicon West 2026 takes place in San Francisco.
Across the Bay
This release expands upon the existing Super Low Outgassing Cable portfolio used by chipmakers in the Bay Area and beyond. The new 1 millimeter configuration follows a design trend of packing more complex, moving electronics into increasingly restricted vacuum chambers.
Hardware vendors working in local cleanroom environments may see these cables implemented as they update existing machinery for higher density chip production. The shift offers a smaller footprint for internal equipment wiring, potentially reducing the downtime associated with machine retrofits.
The takeaway
This new cable provides a compact solution for vendors struggling with tight space constraints in vacuum-sealed equipment. Engineers should watch for product data sheets from the manufacturer to confirm if the 30 million cycle rating meets the specific mechanical demands of their current fabrication tools.
