Electroninks and SIIX expand additive EMI shielding partnership

Electroninks and SIIX Corporation have broadened a strategic collaboration to develop additive EMI shielding for electronics in Japan and other markets. The move gives customers access to prototype spray-coating trials in a specialized ultrasonic environment, with automotive electronics among the target uses.

Why it matters: - Electronics are getting denser and running at higher frequencies, which is making EMI shielding a broader system-level design issue. - The collaboration aims to make conformal shielding easier to adopt by reducing weight, simplifying integration and increasing design flexibility. - The work could affect automotive electronics, power electronics and other assemblies that need lightweight shielding alternatives.

What happened: - Electroninks announced an expanded strategic collaboration with SIIX Corporation on additive high-frequency electromagnetic interference shielding. - The collaboration covers Japan and global markets. - SIIX introduced spray coating equipment and prepared a specialized ultrasonic spray coating environment. - The setup is intended to support prototype coating trials across a wide range of products.

The details: - Electroninks is providing its metal-organic decomposition conductive ink platform and spray coating process knowledge. - SIIX is contributing large-scale electronics manufacturing services infrastructure and global manufacturing reach. - The partners plan to help customers establish and evaluate additive EMI shielding approaches for a broad range of electronics. - Automotive is one of several potential target applications. - SIIX will serve as a distribution and collaboration partner for Electroninks’ EMI shielding materials and processes within Japan. - The companies said they will begin with prototype coating trials rather than immediate volume production. - Electroninks said the platform enables conductive coatings to be deposited directly onto complex geometries using precision spray coating. - The company said the approach creates lightweight alternatives to traditional metal shielding enclosures used in ECUs, Power Control Units and other electronic assemblies. - Electroninks said it provides materials and process knowledge and works with SIIX and customers to jointly define the printing and coating approach for each product. - Process parameters for specific MOD products and customer materials, including automotive plastics such as PBT, are established together during each engagement. - The companies have also created a framework to bring newly developed Electroninks materials into future coating trials. - Electroninks said it has installed advanced spray and printing systems internally to improve process consistency and support future scale-up. - The company’s conductive ink portfolio includes silver, gold, platinum, nickel and copper. - Electroninks said its inks are used in PCB manufacturing, semiconductor packaging, consumer electronics, wearables and medical devices. - Electroninks’ website is More information.

Between the lines: - The collaboration signals a move from materials supply toward joint process development, which can lower adoption barriers for manufacturers that need application-specific tuning. - Starting with prototype trials suggests both companies are positioning the offering as a co-development workflow rather than an off-the-shelf production line. - The emphasis on extending the framework to new materials and settings points to a platform strategy that could broaden use beyond the first set of customer engagements.

What's next: - The companies expect the collaboration to expand into additional applications, manufacturing regions and conductive material workflows. - Future work is expected to support broader electronics and semiconductor packaging markets. - SIIX and Electroninks will continue working with customers to define coating processes for new products as additional materials are introduced.
