Tokyo Seimitsu’s Xslicer SMX-6010 is pitched as a non-destructive X-ray flagship for advanced semiconductor packaging lines, combining 3D CT imaging with high throughput for inline defect analysis in chiplet and 3D-stacked devices. According to Tokyo Seimitsu, the system supports detailed cross-sectional inspection of solder joints, voids and internal interconnects without cutting samples, a critical capability as heterogeneous integration raises quality demands in power and logic packaging.

What the Xslicer SMX-6010 is designed to do on the fab floor

The Xslicer SMX-6010 is an industrial X-ray inspection system that uses computed tomography to reconstruct 3D images of semiconductor packages, enabling engineers to inspect internal structures such as bumps, vias and underfill in fine detail while keeping devices intact. Tokyo Seimitsu’s official product documentation describes the Xslicer series as supporting both 2D and 3D modes to balance speed and analytical depth for production and failure analysis labs. The manufacturer’s product page highlights micro-focus X-ray sources and flat-panel detectors tailored for semiconductor packages rather than general-purpose electronics.

In practice, the SMX-6010 is aimed at quality control tasks such as checking void ratios in solder joints under power devices, confirming alignment in through-silicon vias and inspecting ball-grid array (BGA) connections in high-pin-count packages. Japanese trade coverage of Tokyo Seimitsu’s X-ray portfolio notes that the Xslicer line is being adopted by domestic semiconductor manufacturers and outsourced assembly and test (OSAT) providers that are shifting to more complex multi-die modules. A report by Semiconportal points to growing demand for inline X-ray inspection in power electronics for electric vehicles and industrial drives, areas where voids and cracks can trigger early failures.

The system sits alongside Tokyo Seimitsu’s broader Accretech-branded metrology and probing tools, forming part of a strategy to cover more steps around wafer and package-level process control as chip geometries shrink and packaging becomes a performance driver. Market researchers tracking semiconductor assembly and packaging equipment describe X-ray inspection as one of the faster-growing segments through the next decade, with demand tied to 3D NAND, advanced system-in-package (SiP) and automotive electronics volumes. An industry forecast from OpenPR expects long-term growth in assembly and packaging tools, including inspection, supported by electrification and AI workloads.

For Tokyo Seimitsu, inspection systems such as the Xslicer SMX-6010 complement its established wafer probing and coordinate measuring machine businesses, giving the company a broader footprint at customers that want to consolidate suppliers for metrology and test equipment. According to the company’s latest investor materials, measurement and inspection tools collectively account for a meaningful share of revenue and are viewed as a growth vector alongside front-end semiconductor equipment. Shares of Tokyo Seimitsu (JP3571400005) closed on the Tokyo Stock Exchange at JPY 7,239 on 06/13/2026, reflecting how investors currently price its exposure to semiconductor capital spending cycles.
