The Printed Circuit Engineering Association (PCEA) reports that PCB East 2026 in Worcester, MA saw attendance rise nearly 48% year-over-year, making it one of the largest events in the organization's history.
What Drove the Surge
The electronics industry's urgency around AI infrastructure buildout was the dominant theme:
E-glass and copper foil shortage — AI server demand has strained laminate material supplies globally. The intense focus on AI hardware is creating allocation challenges even for standard FR-4 materials.
Ultra HDI manufacturing — Anaya Vardya's cover story explored why registration, alignment, and tolerance stackup are critical for next-gen designs with <30μm line/space.
Digital twin integration — DFM simulations enabling real-time manufacturing optimization for complex AI server boards.
Key Takeaways
The UHDI Transition
The industry is approaching an inflection point where standard HDI processes (50μm line/space) are insufficient for next-generation AI accelerator designs. Companies investing in mSAP and SAP processes will capture the high-value AI infrastructure market.
Material Supply Reality
- E-glass allocation is real — specify materials 8-12 weeks before fabrication
- AI server boards (20-40 layers) consume disproportionate glass fabric quantities
- Lead time projections suggest constraints through 2027
From Chat to Workflow
Sean Patterson presented on turning ad-hoc AI usage into standardized manufacturing workflows. The key insight: individual engineers using AI tools provides some benefit, but real transformation comes from encoding AI into repeatable organizational processes.
By the Numbers
- Global PCB market: $108B projected by 2028 (from $82B in 2024)
- AI/HPC boards: fastest-growing segment (>25% CAGR)
- Skills gap: widening as designs outpace workforce
- 120+ hours of technical training delivered at the event
