Electroninks expands Japan EMI shielding presence through SIIX ultrasonic spray partnership

Electroninks, the Austin-based maker of conductive inks for 3D printed electronics, is expanding its Japan presence through deeper collaboration with SIIX Corporation, a leading Japanese electronics manufacturing services (EMS) provider. Together they will advance electromagnetic interference (EMI) shielding solutions: SIIX distributes Electroninks materials and processes and contributes a specialized ultrasonic spray coating environment for more flexible, including conformal, alternatives to traditional shielding enclosures. Automotive electronics is an early focus. Rather than a fixed package, the partners will prototype with each customer and scale production methods and material formulations once a preferred workflow is set.

The Japan expansion follows a recent U.S. Air Force contract for on-demand PCB manufacturing and a market-entry deal in India, a coherent push into defense-linked demand and China-diversified manufacturing. Denser, higher-frequency electronics make EMI shielding a system-level constraint where sprayable conductive materials and process co-development matter more than catalog inks alone. Pairing U.S. specialty chemistry with Japanese EMS scale and ultrasonic coating is how materials suppliers embed themselves in production accounts. Electroninks is also refining spray-coating capability in-house, bundling process know-how with formulations.
