Global Electronics Manufacturing – PCBs, Semiconductors, Materials, End Markets, EMS

1. The Week in Two Sentences

AI is still pulling everything forward, and the Middle East is still pushing prices the wrong way. Front-loading by buyers afraid of the next shortage is doing most of the heavy lifting in the April PMIs – real underlying demand outside data-center and defense is mixed at best, and the second half of 2026 is going to test whether what looks like a boom is actually one or just an inventory cycle in disguise.

2. PCBs – $112B Industry, AI is Doing the Work

The world PCB market is on track to clear $112 billion this year (Contexo composite estimate). That is up from $98 billion in 2025 (Data4PCB / TPCA / CPCA) and well above the pre-AI plateau in the $84-$92B range from 2022-2024. China is still 59% of the world by revenue, Korea 11%, Taiwan 10%, and Japan around 7%, but the growth is concentrated almost entirely in the high-end Taiwan, Korea, and Thailand HDI / IC-substrate / advanced multilayer pockets. Korea reported Q4 2025 PCB output of $3,011M, +20% YoY, with flexible boards leading at +25%. Total 2025 Korean PCB output was $10.18B, +5.4% YoY. Taiwan reports the AI sub-segment is what’s driving the numbers – high-layer-count multilayer, ABF substrates, and ultra-low-loss CCL grades up 10-40% in pricing during Q1 alone.

What I would watch: North American bookings softened slightly in Q1 even though shipments improved, suggesting some normalization after a strong late-2025. That’s a tell – if AI demand is the only thing holding up the global number and bookings are easing at the same time, then H2 2026 needs the order book to keep refilling at hyperscaler-pace or the composite will flatten. M8 grade CCL is sold out through 2028 (AMI), so the constraint above is at least as real as the demand below. For now we are sticking with a high-single-digit YoY growth call for the global PCB number through year-end – the 3-month PMI-implied path supports it; the 6-month path is closer to mid-single-digit.

3. Semiconductors – $298.5B in Q1 Alone, Memory Doing the Work

Q1 2026 global chip sales hit $298.5B, +25% sequentially (SIA). That puts the industry on a run-rate clearing the $1 trillion mark before year-end – WSTS now forecasts $975B for 2026 overall after $796B in 2025. By type, memory is leading: +39% YoY for both 2025 and 2026F, on AI-server cannibalization of consumer DRAM/NAND. Logic is +32% YoY in 2026F. Discrete and analog finally turn positive after two ugly years.

2026F Semiconductor Growth by Type – Source: WSTS / SIA, May 11, 2026.

Regionally, March 2026 prints look unreal: Asia-Pacific / All-Other +108.5% YoY, Americas +83.1%, China +74.8%, Europe +46.5%, Japan only +7.4%. Those numbers are partly real demand, partly war-stockpiling, and partly comparison-base distortions from soft Q1 2025. On the equipment side (SEMI / SEAJ 2025): Taiwan $31.5B (+90% YoY) on TSMC 2nm Hsinchu / Longtan ramp, Korea $25.75B (+26%), Japan $9.52B (+22%), North America $10.89B (-20%), Europe $2.86B (-41%). The bifurcation is now extreme – whoever is on the leading-edge AI capex line is booking record orders; whoever isn’t has cut. Year-end call: if oil normalizes and AI infrastructure capex holds, we end 2026 at roughly $975-985B in total semi billings. If Hormuz stays disrupted into Q4, we still clear $950B because memory and logic AI cannot pause.

4. Materials – Shortage List Is Longer Than the Available-Supply List

This is now the bottleneck. Helium and bromine are short because of Iran war disruption. T-glass and specialty glass are tight, lead times running 30+ weeks. ABF substrates are tight at Ibiden and Unimicron. EUV photoresists are JSR’s call – the Taiwan plant is ramping for TSMC. China continues its aggressive 70% self-sufficiency push on 300mm silicon wafers, with Eswin targeting 1.2M wafers/month by late 2026. DRAM and NAND availability for non-AI customers is the worst it has been since 2018 because the hyperscalers are pre-buying. Material companies serving the AI value chain are reporting Q1 revenue growth of 22-42% (ITEQ, EMC, Nan Ya PCB, Elite Material, Mitsubishi Gas BT, Heraeus silver), which is doing a lot of heavy lifting in the PCB and packaging composite.

What we expect by year-end: M8 CCL stays sold-out, T-glass and high-Tg laminates stay tight. DRAM contract pricing rolls up another 8-15% by Q4 vs Q1. China’s wafer self-sufficiency project hits 60-65% by year-end, slightly behind plan but close enough to start pressuring non-China wafer pricing for mature nodes. Helium and bromine ease only if the Strait reopens. Until then, the materials cost layer is sticky-inflationary.

5. End Markets – AI Data Centers Eat Everything; Consumer Squeezed

Global Data Center Expansion Hotspots – 2026 – Source: CCG / industry trackers, May 11, 2026.

Virginia and Texas remain the two largest U.S. data-center clusters (5.2 GW and 4.5 GW respectively in our composite). Greater China clocks roughly 3.8 GW operational and committed, Taiwan 1.5 GW, UK/Ireland 1.8 GW, Frankfurt 1.5 GW. The Luzon hub in the Philippines (4,000-acre Pax Silica build) is now an explicit 1.0 GW de-risking platform. UAE/KSA combined 1.2 GW reflects the Gulf hyperscaler buildout. India 0.8 GW, Japan 1.2 GW, S. Korea 0.9 GW, Australia 0.6 GW. That is the demand pull behind every PCB, semi, materials, and EMS number above. Supermicro guided $11.0-12.5B for the upcoming quarter, Flex is spinning out its Cloud + Power Infrastructure unit to a public 2027 IPO, and Foxconn launched PEARL-1A/1B satellites with SpaceX while Pixxel put a 200kg orbital data-center prototype up – the LEO segment is now a real adjacency.

Below the data center, the consumer story is rough. Q1 2026 smartphone revenue is a record $117B but units came in at ~290M, down 2-4% YoY (Counterpoint). The industry is making more money on fewer phones, which is fine for Apple and Samsung premium-segment margins and hard for everyone else. PC shipments are +6.0% YoY in Q1, lifted by Windows 10 end-of-life replacement cycles in Japan and Europe and by AI PC processor refreshes. Lenovo holds 26.5% share, HP and Dell trail. PC growth peaked at +9.2% in Q3 2025 and is moderating – by Q4 2026 I expect +2 to +4% YoY as the EOL refresh tailwind fades.

6. April PMIs and What They Say About PCBs Through Year-End

The J.P. Morgan Global Manufacturing PMI hit 52.6 in April – the highest reading since March 2022 and the ninth straight month above 50. But read the S&P Global commentary and you will see the same word in every country panel: front-loading. Producers and buyers are pulling forward stock against price increases and Hormuz-driven supply disruption. The future-output expectations sub-index is much softer than the headline, especially in Germany (51.2, but expectations fell sharply) and Eurozone broadly.

Translating PMIs into PCB demand: We expect Taiwan PCB output up 14-18% YoY over the next 3 months and tapering to 10-14% over a 6-month window as the front-loading payback hits. China stays 10-12% (3 mo) and 8-10% (6 mo) on continued AI server and EV pull. South Korea is in the 7-9% range on substrates and memory PCB content. North America runs 6-8% (3 mo) easing to 4-6% (6 mo) – strong AI bookings, soft consumer, and some Q4 working-capital tightening. Europe stays the weakest of the regions at 2-4% across both windows; Germany’s manufacturing momentum is borrowed time.

7. EMS Composite and SWOT

Global EMS Q1 2026 Revenue Growth + Mid-2026 SWOT – Source: WSTS / S&P PMI / IPC / TPCA / CCG composite.

EMS is split by who has AI server backlog and who does not. Foxconn FII reported Q1 revenue of CNY 251.08B and net profit +102.5% YoY. OSI Systems posted record $453.2M Q3 revenue with a $1.9B backlog. Quanta Cloud Technology is up ~38% YoY on Nvidia GB200/GB300 platforms. Pegatron, Inventec, Wistron (now under Tata Electronics in India), and Mexican/SE Asian Tier 1s are pulling steady 14-28% YoY. Western-listed mid-caps Sanmina, Benchmark, and Plexus run 8-16% – solid but not in the AI superstar bucket.

The SWOT chart above captures what I’d put in any executive’s hands at this point in the year: AI server backlog through 2027 is a real strength; CCL/M8 sold-out through 2028 is both a strength and a structural weakness; Pax Silica + Luzon + LEO is the genuine opportunity; Hormuz, materials shortages, and front-loaded order books are the threats. If H2 prints organic demand that is 60-70% of the front-loaded H1 run-rate, we still end the year strong. If H2 organic demand is only 40-50%, we have a Q4 inventory hangover even with AI capex holding.

8. Where We End 2026 – Jon’s Call

Segment	Year-End Growth	Pricing Direction	Shortage Risk
World PCB market	+13-15% YoY ($112B)	High-end +10-40%; commodity flat	CCL M6-M10 critical
Semiconductors	+26% YoY ($975-985B)	Memory +8-15%; logic firm	High – advanced pkg
EMS / ODM	+18-22% (AI-aligned)	Mix-driven margin expansion	Moderate
Materials	+22-35% (specialty)	Sticky-inflationary	High
AI servers / DC	Robust, no slowdown	Premium, demand-driven	GPU + cooling
Consumer PC	+3-5% (EOL fade H2)	Modest +1-3%	Low
Smartphone	Revenue +5-7%; units -2%	Up on premium mix	Low

By region, our year-end map: Taiwan stays at the top – PCB output up 15-18% YoY, semi-equipment imports holding the new $30B+ run-rate, PMI staying above 55 absent a Hormuz reopening shock. China runs 10-12% in PCB output and benefits from anti-involution policy raising margins even where volumes plateau – 2026 profit growth >> revenue growth. South Korea and Japan run 5-8% steady, anchored by memory and substrates. North America runs 6-9% with the AI bookings firm but consumer and industrial mixed; Mexico nearshoring continues to scale. Europe is the laggard at 2-4% headline, with Germany barely above flat in organic terms and the Eastern periphery (Russia 48.1, Poland 48.8) in continued contraction. Southeast Asia keeps expanding – Vietnam, Thailand, Malaysia, Philippines – on Pax Silica de-risking, with the Luzon hub providing structural new capacity. The full-year takeaway: 2026 ends as the best PCB/semi/EMS year on record by dollars, on the back of an AI super-cycle that masks a softer underlying consumer market and an inflationary materials layer that no one has solved.
