Junkosha Debuts New 1 mm Pitch Vacuum Cable
The narrow cable enables denser hardware configurations for chip manufacturers while maintaining high-cycle durability.
Updated on Oct. 15, 2026 in Semiconductors
Junkosha debuted a new 1-millimeter pitch cable designed for high-vacuum semiconductor manufacturing equipment at Semicon West 2026. The product is the latest addition to the company's Super Low Outgassing Cable portfolio, aimed at minimizing space requirements in complex vacuum environments.
Why it matters
As chip manufacturing equipment requires increasingly complex movement within ultra-high vacuum chambers, this development allows vendors to maintain established internal designs while utilizing narrower cabling. It addresses the ongoing industry constraint of fitting high-performance components into shrinking physical spaces.
The new cable features a 1 mm pitch configuration, enabling tighter integration compared to previous standard cables. The component is rated for a 30 million cycle lifespan when tested at a 70 mm bending radius.
The players
Junkosha
A developer of specialized fluoropolymer-based cables and tubes designed for high-vacuum and semiconductor manufacturing environments.
The details
The cable is engineered to function within high vacuum environments, where reducing outgassing—the release of trapped gases from materials—is essential to prevent contamination of sensitive silicon wafers. By utilizing narrower construction, the cable minimizes the need for equipment redesigns in chambers with limited space. The product design was validated through collaborative testing with equipment vendors to confirm mechanical durability during repeated motion.

The Tech Race
This cable launch extends Junkosha's existing Super Low Outgassing Cable portfolio by addressing the physical space constraints of modern vacuum chambers. It marks a push to optimize hardware footprints for semiconductor vendors who must maintain high-cycle durability without modifying established equipment architectures.
Equipment manufacturers can integrate this 1 mm pitch cable into their existing vacuum chamber designs to accommodate tighter layouts. The product is intended for high-cycle motion workflows, though availability and pricing details for vendors have not yet been disclosed.
The takeaway
This development highlights the industry focus on miniaturizing hardware for ultra-high vacuum environments without sacrificing cycle life. Future milestones will include the adoption rates of this cable within next-generation semiconductor equipment designs.
