Eindhoven, The Netherlands – July 21, 2026 – Keiron Printing Technologies, the pioneer of Laser-Induced Forward Transfer (LiFT) precision solder paste printing, has closed a €20.7 million Series A round co-led by Invest-NL, DeepTech Capital Partners and Waves Capital. The company is tackling one of the most costly challenges in electronics manufacturing.
Solder paste printing causes more than 70% of all printed circuit board assembly (PCBA) defects, in a global electronics assembly market worth over €600 billion a year. For decades, manufacturers have accepted this as a limit on reliability, speed and yield.
Keiron's HF2 LiFT Printer replaces the stencil printer, the jet printer and the solder paste inspection (SPI) system with a single digital, non-contact platform. According to the company, it raises first-pass yield from the industry-typical ~60% to above 95%, halves production lead time, eliminates stencils, doubles uptime and makes programming 10 times faster. For high-mix, low-to-medium-volume manufacturers, this means higher throughput, less working capital, better cash flow and stronger EBITDA.
The need is particularly strong in next-generation AI hardware, where components with up to 10,000 interconnects push conventional printing beyond its limits and yields remain extremely low. By depositing paste at nanolitre precision without touching the board, LiFT can handle this level of complexity.
Ramphastos Investments, Singapore-based deep-tech fund ATUM Ventures, Cottonwood Technology Fund and TNO Ventures also joined the round, with ATUM extending Keiron's reach into Asia. The capital will fund a production ramp-up, expanded commercial and support operations across Europe, North America and APAC, and R&D on next-generation LiFT platforms.
"Keiron isn't patching a problem the industry has lived with for decades," said Paul Rooimans, CEO and founder of Keiron Printing Technologies. "We're removing it, for good." He added that the funding will help bring the HF2 onto more production lines, faster, without compromising precision.
"AI, defence growth and rising manufacturing complexity are increasing the need for digital transformation in EMS," said Hessel Mittelmeijer, Investment Manager and Sustainability Officer at DeepTech Capital Partners. "Keiron addresses one of the industry's biggest production challenges with a scalable, digital approach. That's why we led the seed round and continue to back the company."
