Wuxi CSPT×iTGV 2026 Expo Highlights New EU Compliance Demands for Glass-Based 2.5D/3D Packaging

The CSPT×iTGV International Advanced Packaging Ecosystem Exhibition opened on May 28, 2026, at the Wuxi International Convention Center, spotlighting emerging compliance requirements for glass-based substrates and 2.5D/3D IC integration technologies—particularly in light of the upcoming EU CE-RED regulatory update.

Confirmed Event and Regulatory Context

From May 28 to 29, 2026, the CSPT×iTGV International Advanced Packaging Ecosystem Exhibition was held at the Wuxi International Convention Center. The event centered on glass via (iTGV), glass circuit board (GCP), and 2.5D/3D IC integration technologies. Concurrently, the draft revision of the EU CE-RED directive—scheduled to take effect in Q3 2026—introduces mandatory EMC testing requirements for high-frequency signal integrity and thermal diffusivity specifically for glass-based packaged devices. Several Chinese equipment and materials suppliers exhibiting at the event—including HuaHai QingKe and Kaida Microelectronics—have completed pre-audit for dual certification under IEC/EN 62368-1 and EN 55032.

Impact Across Supply Chain Roles

Export-Oriented Manufacturers

These companies face new technical validation thresholds before shipment to EU markets. The inclusion of signal integrity and thermal diffusivity in CE-RED’s EMC scope means that functional performance—not just electromagnetic emissions—now directly affects market access. Pre-market testing protocols must be updated accordingly.

Raw Material Suppliers

Suppliers of specialty glass substrates and low-CTE dielectrics must now align material specifications with both electrical and thermal test parameters defined in the draft standard. Documentation supporting thermal diffusivity values and high-frequency transmission loss becomes a prerequisite for downstream qualification.

Contract Manufacturers & OSATs

Assembly and test service providers must verify process stability across thermal cycling and RF stress conditions. Process control records, especially for glass substrate handling, metallization uniformity, and TSV/GCP interconnect reliability, are increasingly scrutinized during certification audits.

Supply Chain Service Providers

Logistics, testing labs, and regulatory consultants must expand service offerings to include thermal-electromagnetic co-validation support. Lab accreditation for EN 55032-compliant measurements under glass-substrate-specific boundary conditions is now a competitive differentiator.

Key Compliance Priorities for Enterprises

Accelerated Certification Pathway Alignment

Firms targeting EU entry should prioritize alignment with the IEC/EN 62368-1 + EN 55032 dual-certification framework—already demonstrated by early-adopter exhibitors—as the de facto benchmark for CE-RED readiness.

Thermal-Electrical Co-Validation of Substrates

Glass substrate vendors and integrators must jointly develop test reports covering both high-frequency insertion loss (per EN 55032 Annexes) and thermal diffusivity (measured per ISO 22007-2 or ASTM E1461), as these metrics are now explicitly referenced in the CE-RED draft.

Supplier Qualification Documentation Upgrade

Purchasing departments must revise supplier evaluation checklists to require certified thermal diffusivity data, RF characterization reports, and traceable process capability indices (C_pk) for glass via formation and redistribution layer patterning.

Pre-emptive Technical Bid Coordination

For tenders referencing CE-RED 2026, procurement teams should proactively engage with engineering and compliance units to ensure technical specifications include clauses for thermal-electromagnetic co-testing—avoiding post-submission compliance gaps.

Industry Observation: Beyond Conformance Toward Integration Readiness

Analysis shows this shift reflects a broader trend: regulatory frameworks are evolving from component-level safety and emission checks toward system-level functional integrity assessments. What deserves closer attention is how the coupling of thermal and electromagnetic validation may compress supplier qualification timelines—especially for novel glass-based platforms where reference test methodologies remain under development. From an industry perspective, manufacturers investing in co-simulation tools (e.g., thermal-aware EM solvers) and cross-functional lab capabilities are likely to gain first-mover advantage in CE-RED-aligned supply chains.

Strategic Implications for Global Packaging Ecosystems

This event marks a turning point where advanced packaging transitions from a purely technological frontier to a regulated domain governed by integrated physical performance criteria. The convergence of glass substrate innovation and tightening EU regulatory scrutiny underscores that compliance is no longer a final gate—but a design constraint embedded from R&D through qualification. A rational interpretation is that success will favor firms with vertically aligned material-process-test capabilities, rather than those relying solely on modular certification outsourcing.
