Spirox Debuts SP7000G to Scale Glass Core and TGV Production

The SP7000G system utilizes laser tomography to identify internal microcracks in glass substrates after metallization and ABF build-up. The machine performs a full-panel scan of a 510 mm by 515 mm substrate in under 20 minutes, a speed aimed at streamlining quality control for next-generation AI server components.

Industry partners, including Corning and DNP, emphasized that non-destructive inspection is critical as Glass Core technology moves from R&D into mass production. Corning’s Odessa Petzold noted that the laser scanning approach allows for defect detection without compromising the integrity of delicate glass structures. DNP’s Satoru Kuramochi added that such reliability analysis is essential for maintaining yields in large-scale server packaging.

Spirox executive Paul Yang stated that the SP7000G complements the company’s existing SP8000G model. Together, these tools form a specialized suite for TGV (Through-Glass Via) inspection, covering the entire lifecycle from initial development to high-volume output. This expansion reflects a broader effort to build a robust ecosystem for advanced packaging, where monitoring defect distribution is key to optimizing manufacturing efficiency.
