Keiron Printing Technologies, an Eindhoven, Netherlands-based developer of laser-induced forward transfer (LiFT) solder paste printing systems, has raised €20.7M in Series A funding. The round was co-led by Invest-NL, DeepTechXL and Waves Capital, with Ramphastos Investments, ATUM Ventures, Cottonwood Technology Fund and TNO Ventures participating. Keiron's HF2 LiFT Printer replaces stencil printers, jet printers and solder paste inspection systems with a single contactless digital platform that achieves nanoliter-level precision and eliminates consumables. The capital will fund production ramp-up, geographic expansion across Europe, North America and APAC, and next-generation platform development.
Stencil Limits Exposed by AI Hardware
The timing aligns with mounting pressure on conventional SMT equipment. Solder paste printing remains the single largest source of defects in electronics assembly, accounting for over 70% of PCBA issues in a market worth more than €600 billion annually. Pragmatic Semiconductor raised £182M Series D in December 2023 for flexible electronics, underscoring investor interest in advanced printing technologies, though Keiron's focus remains on high-reliability SMT assembly.
Yield Crisis in Electronics Assembly
Traditional stencil printing delivers roughly 60% first-pass yield, forcing manufacturers into costly rework loops. The process requires physical stencils, frequent cleaning cycles and long changeovers that limit flexibility in high-mix, low-volume production. High-reliability sectors such as aerospace, defense, medical and automotive cannot tolerate these defect rates as component densities rise.
Single Platform Replaces Three Machines
Keiron's LiFT approach deposits solder paste via laser without nozzles or stencils, supporting standard Type 4-6 pastes and 01005 components. The integrated 3D Solder Paste Volume Metrology provides real-time inspection, removing the need for a separate SPI machine. First-pass yield rises above 95%, programming becomes ten times faster and production uptime doubles compared with legacy lines.
As CEO Paul Rooimans stated:
"Solder paste printing has been the industry's most expensive open secret for decades – a failure driver on a market worth well over €600 billion a year that everyone lived with because no one could fix it."
DeepTech and Government Backers Signal Scale
The investor group combines deep-tech specialists with state-backed capital. Invest-NL and TNO Ventures provide institutional validation while DeepTechXL and Cottonwood Technology Fund bring prior seed-stage support. The syndicate's composition indicates conviction in European manufacturing sovereignty and the shift toward software-defined production equipment.
SMT Equipment Growth Fuels Replacement Cycle
The solder paste printers market is projected to expand from $2.8B in 2025 to $4.6B by 2033 at 6.8% CAGR. Broader SMT equipment spending is expected to grow from $6.1B in 2026 to $14.2B by 2033 at 12.8% CAGR. Incumbents including ASMPT (DEK), Mycronic and ITW EAE (MPM) continue to refine stencil and piezo-jet systems, yet none currently offer a single platform that removes all three process steps.
What's Next
With first U.S. deployments at Distron Corporation and a European roadshow completed, Keiron plans to scale from eight installed machines in 2025 to 100 machines by 2027 while expanding distribution in North America and APAC.
