Electroninks to demo spray-coated silver ink for EMI shielding at SEMICON Taiwan

Electroninks will showcase its EI-1207 spray-coated MOD silver ink at SEMICON Taiwan 2026 in Taipei from Sept. 2-4, positioning the vacuum-free process as an alternative to sputtering for EMI shielding and advanced packaging. The company says the film can improve sidewall coverage, throughput and shielding performance while fitting into existing manufacturing lines.

Why it matters: - Electroninks is pitching spray-coated MOD silver ink as a way to replace or reduce reliance on sputtering for EMI shielding and advanced packaging. - The process is designed to improve sidewall coverage, simplify manufacturing and raise throughput. - The company is using SEMICON Taiwan 2026 to show reliability data and live demonstrations to semiconductor customers and partners.

What happened: - Electroninks will exhibit at SEMICON Taiwan 2026 from Sept. 2-4 at the Taipei Nangang Exhibition Center in Taipei. - The company will show its MOD silver ink portfolio at booth #M1248, co-located with manufacturing partner MANZ. - A full roster of Electroninks executives will be on-site to meet customers, partners and industry stakeholders. - The attending team includes President and Co-founder Melbs LeMieux, Director of Sales and Business Development Takashi Mochizuki, APAC Sales Director Brian Liu, Director of Sales & Technical Services Johnson Ke, Global Technical Director Kazutaka Ozawa, Taiwan Application Development Manager Kang-Yu Liu, Engineers Linus Wu, Charlie Chiu and Jet Cheng, and Operations Manager Johnny Hsieh.

The details: - Electroninks will highlight EI-1207, a particle-free, polymer-free silver MOD ink for spray coating and inkjet printing in EMI shielding and advanced packaging. - The ink supports non-line-of-sight deposition, cures in air and delivers immediate metallization, good sidewall and corner coverage, higher metal purity and low sheet resistance. - Spray coating is not limited by line-of-sight physics, which enables uniform sidewall coverage up to 100% aspect ratio in package geometries with narrow spacing. - Current state-of-the-art metalization reaches roughly 40% sidewall coverage, according to the company. - Electroninks says that coverage advantage can eliminate the reconstitution step used in traditional workflows. - The company says the result is fewer process steps, higher units per hour and more packages per wafer ring. - Electroninks plans to present reliability and shielding effectiveness data for EI-1207 spray-coated films. - The films achieve greater than 30 dB of shielding across 1 MHz to 1 GHz at 2 microns of film thickness. - The films reach up to 60 dB at 1.2 microns or 80 dB at 3 microns across the 1 to 40 GHz range. - The films maintain stable adhesion and electrical resistance through reliability testing and have passed customer qualification. - Electroninks’ broader MOD ink platform includes the EI-12xx and EI-14xx series for spray coating and the EI-7xx and EI-11xx series for inkjet printing. - The platform offers a range of process temperatures, resistivity and adhesion profiles for different packaging and interconnect requirements. - More information on Electroninks products and solutions is available at the company’s website.

Between the lines: - Melbs LeMieux said Electroninks’ EMI-shielding metalization products have been in qualification and reliability testing for the past couple of years. - LeMieux said customers are now looking at the technology for cost and throughput benefits as well as functional advantages. - LeMieux said spray-coated MOD silver provides sidewall coverage that sputtering cannot reach and offers ESG benefits. - The event gives Electroninks a chance to move the story beyond lab and qualification data and into manufacturing demonstrations.

What's next: - Electroninks will give live spray-coating demonstrations at booth #M1248. - The company plans to discuss how MOD ink technology can be integrated into existing manufacturing lines. - Semiconductor customers will be watching for evidence that the process can scale while preserving shielding performance and reliability.

The bottom line: - Electroninks is using SEMICON Taiwan 2026 to make the case that spray-coated silver ink can offer a faster, vacuum-free route to EMI shielding with stronger coverage and manufacturing efficiency than sputtering.
