V5 Technologies ($7822.TW) has become a quiet beneficiary and enabler of the #CoWoS boom because inspection is where advanced packaging's economics get decided. As #AI accelerators stack more dies and #HBM layers, catching subtle defects while sustaining yield has become the core pain point for foundries and OSATs, turning inspection equipment into one of the hottest niches in the supply chain.

V5's contribution is its V530 Pro platform, which performs AI-driven optical detection of contamination, scratches, and residues on advanced packages, pairing proprietary AI image recognition with high-speed imaging hardware. The payoff has been dramatic: revenue surged roughly 188% in 2025 to NT$2.08 billion with EPS of NT$14.04, and record monthly revenue continued into mid-2026 as customers kept expanding CoWoS, 3D, and panel-level capacity.

In effect, V5 monetizes every increment of CoWoS capacity added, and its customer base is broadening from Taiwanese wafer fabs to OSATs like ASE and SPIL - a sign AI optical inspection has become an industry standard.

The company sees #CoPoS as an even larger opportunity: it's on the ground floor, and inspection intensity is higher. V5 appears on TSMC's initial CoPoS vendor list in the inspection and automation category, and because CoPoS is an entirely new process, inspection and metrology tools enter the line first to validate each process step before the ramp - meaning V5's equipment leads rather than follows the capacity build.

The technical challenges of panels are the moat: large square panels are harder than wafers in dimensional control, stability, and precision, and panel warpage is a serious problem for optical tools with limited depth of field - so V5 developed the V5P310 Pro with multi-point vacuum chucking and proprietary high-speed imaging to address it.

Commercially, this means more content per line at higher prices: V5 offers four CoPoS machine types versus two for CoWoS, priced meaningfully higher due to warpage-handling mechanics; a demo machine is already at a customer, three panel-level packaging customers are engaged, and CoPoS inspection demand is estimated at roughly double that of CoWoS. With qualification expected as early as Q4 2026 and volume shipments in 2027, CoPoS is positioned to become V5's next growth leg just as the CoWoS cycle matures
