Poptávka po deskách plošných spojů pro servery s umělou inteligencí v roce 2026

AI server hardware is the single largest force reshaping the PCB industry in 2026. The change is not incremental — it is a step-function move in PCB content value, material grade, layer count and supplier concentration. Per Morgan Stanley’s May 22, 2026 BOM teardown of NVIDIA’s upcoming Vera Rubin VR200 NVL72 rack, PCB content value per rack rose 233% generation-over-generation — from approximately $35,100 on GB300 to approximately $116,700 on VR200. The same report shows MLCC content value up 182%, ABF substrate up 82%, and the full rack ASP at approximately 7.8 milionu $ — nearly double the current GB300 rack.

This guide walks through the technical and material changes inside the Rubin platform, the supplier ecosystem that builds it, and the propagation effect on PCB material allocation for everyone else. The pricing context is in the PCB price increase analysis, the underlying material economics in the PCB raw material costs guide, supply concentration in the PCB material shortages analysis, and design and procurement responses in the guide to reducing PCB costs.

1. The Headline Number: $35,100 → $116,700 per Rack

Morgan Stanley’s bottom-up BOM teardown of the NVIDIA Vera Rubin VR200 NVL72 rack — published by analyst Howard Kao on May 22, 2026 — established the headline numbers for AI server PCB economics in 2026. Among all downstream components, PCB content value posted the largest year-over-year increase:

Translated into per-square-meter terms, multi-layer PCBs for general electronics in 2026 are running approximately 204 dolaru za metr čtvereční according to industry teardown data via Reuters, while the high-end AI server boards reach approximately 1,970 dolaru za metr čtvereční — blízko 10× the standard rate. The difference is material-driven: layer count, CCL grade, copper-foil profile, glass cloth grade and surface finish all sit at the premium tier of their respective categories.

Why is AI server PCB content rising 233% generation-over-generation->

Because Rubin combines two effects. First, the existing PCB types are getting larger and more complex — Rubin’s compute board upgrades from a 22-layer HDI PCB on GB300 to a 26-layer board, with material grade moving from M7 to M8. Second, Rubin introduces entirely new PCB modules that did not exist on GB300, including the Midplane PCB (18 units per rack at $1,500 each) and the ConnectX module PCB (72 units per rack at $270 each). These two new types alone contribute approximately $46,400 in added PCB content value per rack.

2. Why a Rubin VR200 NVL72 Costs $7.8 Million from the ODM

Morgan Stanley’s analysis estimates the full Rubin VR200 NVL72 rack at approximately $7.8 million from the ODM, with even higher prices through OEM channels such as Lenovo, Asustek, Giga-Byte and Dell. This is nearly double the current GB300 rack at under $4 million. The increase is broad-based across the BOM:

• Memory is the largest single driver. Memory share moved from 5-10% of the GB200 NVL72 BOM to 25-30% of the VR200 BOM. The absolute memory cost rose from approximately $370,000 (GB300) to approximately $2 million (VR200) — a 435% increase driven by both higher HBM content and the underlying memory market repricing.
• GPU silicon dollar value rose 57% — from approximately $2.52 million to approximately $3.96 million per rack — but GPU share of total BOM klesl from approximately 65% to approximately 51% because memory and other components grew faster.
• PCB content surged 233% from approximately $35,100 to approximately $116,700 per rack, on the back of higher layer counts, premium CCL grades, and entirely new PCB modules (Midplane, ConnectX) introduced by Rubin.
• MLCC content grew 182% from approximately $1,530 to approximately $4,320 per rack. A single VR200 rack now uses approximately 600,000 multilayer ceramic capacitors, more than 30% above the GB300 count.
• ABF substrate value grew 82%, reflecting both the larger substrate area required for Rubin GPUs and the same T-glass-driven cost pressure that touches CCL.

3. The CCL Grade Ladder: M6 → M7 → M8 → M9 Q-Glass → M10

The technical reason for AI PCB cost growth is the move up the CCL grade ladder. Each step changes resin chemistry, copper-foil profile and glass-cloth grade at the same time, multiplying material cost rather than adding to it. The progression from H100 / GB200 through Rubin Ultra spans five M-grades in approximately three generations.

The cost multiplier up this ladder is dramatic. Per industry data: M6 CCL runs roughly 3-5× standard FR-4; M7 runs 6-9×; M8 runs 10-15×; M9 Q-glass runs 15-20×. The next-generation M10 grade currently in qualification (Df <0.002) extends the ladder further. On March 13, 2026, analyst Ming-Chi Kuo confirmed that NVIDIA had partnered with Wus Printed Circuit to test M10 CCL for 448G+ signaling, with the test boards using next-generation HVLP5 copper foil and Q-glass cloth.

What is Q-glass and why does it matter for AI->

Q-glass is glass fiber cloth made from high-purity quartz fiber (~99.99% SiO₂). It has a dielectric constant Dk of approximately 3.0 and a dissipation factor Df of approximately 0.0007 — both materially lower than NE-glass and T-glass. At 224G and 448G data rates, the entire signal path’s loss budget is so tight that the residual loss from glass-weave non-uniformity becomes a controlling factor. Q-glass reduces this loss by lowering the bulk dielectric constant of the reinforcement itself. The leading Q-glass suppliers are Shin-Etsu, Asahi Kasei, Glotech, Feilihua, Taishan Fiberglass and Hong Ho.

4. Layer Count Inflation: From 22 to 26 to 44 to 78 Layers

The progression in PCB layer count for NVIDIA AI compute boards has accelerated over the past three generations:

• H100 compute board: ~22 layers.
• GB300 compute board: 22-34 layers depending on the configuration.
• Rubin VR200 compute board: Vrstvy 26 (per Morgan Stanley teardown), upgraded from GB300’s 22-layer HDI.
• Rubin VR200 midplane PCB: dosáhnout Vrstvy 44 for the highest-rate interconnect plane in the rack.
• Rubin LPX: přibližně 52 layers on M9 Q-glass.
• Rubin Ultra / Kyber: projected at approximately 78+ vrstev.

Each layer added to a PCB roughly increases fabrication cost by 20-30% because each layer adds a CCL core, a prepreg, a lamination cycle, drilling, plating and registration risk. Doubling from 22 to 44 layers does more than double cost — it multiplies it because of the compounding lamination cycle count, hole-aspect-ratio difficulty, and registration tolerance buildup. By the time the design reaches 78 layers on Q-glass, every step of the fabrication process is at the boundary of what current equipment supports.

5. The Midplane PCB and ConnectX Module — Two New PCB Types

Rubin introduces two PCB types that were not present on GB300, and per Morgan Stanley’s BOM teardown they alone contribute approximately $46,400 of new PCB content value per rack:

• Midplane PCB. 18 units per rack at approximately $1,500 unit price. The midplane is the giant interconnect PCB that ties together compute boards into the unified NVLink fabric across the entire NVL72 rack. Layer counts reach 44 with Q-glass dielectric, requiring HVLP4 or HVLP5 copper foil to maintain 224G channel integrity over the long span. ABF and BT substrate makers cannot easily make boards this large; this is PCB territory.
• ConnectX module PCB. 72 units per rack at approximately $270 unit price. Each ConnectX-8 module sits as a daughter card to a compute board, providing the NICs for the rack-level network. The ConnectX PCB itself is a smaller HDI board built on M7 or M8 CCL with HVLP foil and tight impedance control.

Each of these new PCB types requires premium CCL grade, premium copper foil profile, and specialty glass cloth — all categories already constrained by Section 7 below. The cumulative effect is that NVIDIA Rubin has materially increased the demand for the same scarce material grades that 5G base-station, automotive radar, and high-end networking PCB customers also depend on.

How does the new midplane PCB compete for materials with the rest of the industry->

It competes directly. The midplane uses the same Q-glass cloth supplied by Nittobo, Shin-Etsu and Asahi Kasei that next-generation 5G millimeter-wave PCBs need. The same HVLP4/HVLP5 copper foil from Mitsui Kinzoku that radar and high-rate networking boards need. The same M8/M9 CCL from Doosan, Panasonic, Resonac and Shengyi. NVIDIA’s Rubin allocation absorbs leading-edge material capacity at every layer.

6. The AI Server PCB Supplier Lineup

The AI server PCB supply chain has consolidated around a relatively small set of qualified producers across PCB fabrication and CCL supply. The ecosystem behind NVIDIA’s Rubin compute boards, midplanes and ConnectX cards:

The PCB fabricators in this list — Unimicron, Wus, Zhen Ding, Compeq, Victory Giant, TTM — collectively absorb most of the AI server PCB volume. Technologie Zhen Ding announced approximately US$1.58 billion in 2026 capital expenditure (+60% YoY) and is building approximately 10 new factories. Wus Printed Circuit is the lead test partner for NVIDIA’s M10 CCL qualification per the Ming-Chi Kuo report on March 13, 2026. Doosan Corporation Electro-Materials in South Korea has reportedly been the exclusive CCL supplier for GB300 compute trays.

7. How AI Demand Pulls Material Allocation from Everyone Else

The propagation of AI demand through the material supply chain is the single most important PCB story of 2026 for non-AI buyers. Hyperscale AI customers — building Rubin VR200 racks for OpenAI, Google, Microsoft, Amazon, Oracle, Meta, xAI and other large data-center operators — have effectively pre-reserved much of the available capacity at every leading-edge material producer:

• Mitsui Kinzoku MicroThin copper foil — 2026 orders exceed installed capacity at the leading producer of premium HVLP foil.
• Nittobo T-glass and Q-glass cloth — orders backlogged into the following year’s Q2 at approximately $100/kg.
• Panasonic Megtron 6/7, Doosan high-end CCL, MGC/Resonac CCL — moved to allocation-based supply.
• Topoint / Union Tool / Zhongwu micro-drills — utilization above 90%, supply unable to meet demand.
• Atotech / Uyemura plating chemistry — premium ENIG and electroplating capacity allocated to high-margin AI server programs.

What this means in practice is that even if a non-AI buyer is willing to pay 2024-equivalent prices for premium CCL or HVLP foil, the material is not necessarily available because hyperscale AI buyers have placed forward orders that take priority. The Korea Customs Service data — CCL import prices reaching $20,728 per ton in March 2026, up 74.5% year-on-year, the first time on record above $20,000/ton — is one quantitative reflection of this allocation rationing.

8. What Non-AI Buyers Are Now Experiencing

For industries that do not buy AI server PCBs but use the same underlying materials, the 2026 cycle has produced uncomfortable effects on lead time, pricing and material availability:

• Telecom and networking equipment OEMs. 5G base stations, switches and routers depend on PPE-based mid-loss CCL (Megtron 6 class) — the same material families AI consumes. Many are facing 14-18 week lead times and 20-40% price increases on the same grade they purchased in 2024.
• 5G infrastructure providers. Direct PPE-resin exposure from the upstream supply event. Some designs have been temporarily re-engineered onto thicker or higher-grade stackups to maintain channel performance with available material.
• Automotive electronics (especially 77 GHz radar). Specialty PTFE / hydrocarbon laminates (Rogers RO3000/RO4000 class) are also AI-allocated for hyperscaler high-frequency programs. Automotive radar production now depends on qualifying alternative laminate grades or accepting longer lead times.
• Industrial control, power and consumer electronics. Standard FR-4 absorbs displaced demand from premium-grade buyers; lead times have stretched from 2-3 weeks to 6-8 weeks. Even buyers fully insulated from AI-grade material exposure see the propagation effect.
• RF / aerospace defense. Specialty PTFE Rogers-type material is less directly exposed but lead times have extended as Rogers, Taconic and Arlon allocate capacity to higher-margin hyperscaler programs.

What can a non-AI OEM do in 2026->

The realistic response combines four moves: (1) qualify a second CCL grade per board to give the fabricator an allocation alternative; (2) extend forecasts to 12-26 weeks rolling so the fabricator can secure CCL allocation against your demand; (3) audit designs for over-specification — M7 specified where M6 fits, HVLP foil specified where LP fits, ENIG specified where OSP fits; (4) use hybrid stackups that drop premium CCL on non-critical layers. These are covered in detail in the cost reduction guide.

9. AI Server PCB Demand FAQs

How much PCB does a NVIDIA Rubin VR200 rack actually contain->

Per Morgan Stanley’s May 22, 2026 BOM teardown: approximately $116,700 of PCB content per rack, up from approximately $35,100 on GB300 — a 233% generation-over-generation increase. This includes compute boards (now 26 layers on M8), midplane PCBs (18 units at approximately $1,500 each, up to 44 layers on Q-glass), ConnectX module PCBs (72 units at approximately $270 each), and other rack-level PCBs.

Why is the Rubin compute board upgrade from 22 layers to 26 so significant->

Because the compute board carries every high-rate channel between the Rubin GPU complex and the rest of the rack. The increase from 22 to 26 layers added new routing layers for higher channel count, and at the same time the CCL grade moved from M7 to M8 with HVLP4 copper foil. Each step is a material-cost multiplier — the combined effect (more layers + grade upgrade + foil profile upgrade + glass cloth upgrade) produces the 233% PCB content increase Morgan Stanley reports.

What is M9 Q-glass and when is it used->

M9 Q-glass is the most advanced CCL grade in volume production in 2026 — Dk approximately 3.0, Df approximately 0.0007. The dielectric uses Q-glass (high-purity quartz fiber) cloth, HVLP4 or HVLP5 copper foil, and a PTFE-hydrocarbon or specialty resin system. It costs roughly 15-20× standard FR-4. M9 Q-glass is used in Rubin LPX boards (approximately 52 layers) and Rubin Ultra Kyber boards (approximately 78+ layers).

What is M10 CCL->

M10 is the next-generation CCL grade currently in qualification, targeting Df below 0.002 for 448G+ signaling. On March 13, 2026, analyst Ming-Chi Kuo confirmed that NVIDIA and Wus Printed Circuit were testing M10 CCL using HVLP5 copper foil and Q-glass cloth. M10 is not yet in volume production.

Who supplies the PCBs for NVIDIA’s Rubin platform->

The lead Taiwanese AI server PCB fabricators include Unimicron, Wus Printed Circuit, Zhen Ding Technology, Compeq and Gold Circuit Electronics. Chinese fabricators include Victory Giant Technology, Shennan Circuits and Suntak Technology. US-based Technologie TTM supplies selected hyperscaler programs. Wus Printed Circuit is the lead test partner for NVIDIA M10 CCL qualification per industry reporting.

Who supplies the CCL for NVIDIA’s Rubin platform->

Multiple major CCL makers: Panasonic (Megtron series), Doosan Corporation Electro-Materials, Resonac, Mitsubishi Gas Chemical, EMC (Elite Material), TUC (Taiwan Union Technology). Doosan reportedly supplies the exclusive CCL for GB300 compute trays. Chinese CCL makers including Shengyi Technology have reportedly broken into the NVIDIA supply chain.

Why is the midplane PCB so important->

Because it connects all 72 GPUs in the NVL72 rack into a single high-speed compute fabric. Layer count reaches 44 on Q-glass cloth, with HVLP4/HVLP5 copper foil. Per Morgan Stanley, 18 midplane PCBs per rack at approximately $1,500 each contribute approximately $27,000 of new PCB content that did not exist on GB300.

How does AI server PCB demand affect prices for industrial and consumer PCBs->

Through allocation rationing on shared materials. Mitsui Kinzoku copper foil, Nittobo glass cloth, Panasonic/Doosan/MGC/Resonac CCL, and surface-finish chemistry from Atotech and Uyemura are all common inputs across PCB grades. When hyperscale AI buyers pre-order capacity at premium prices, the residual is what serves industrial, automotive and consumer demand — at higher prices and longer lead times.

How fast is the AI server PCB market growing->

Per Morgan Stanley, the PCB content per Rubin rack rose 233% over GB300 — a single-generation step. The MLB (multilayer board) circuit copper foil market is projected to grow from approximately 15,000 tons in 2025 to 31,000 tons by 2028 and 54,000 tons by 2030. HVLP copper foil is growing at approximately 18.3% CAGR per QYResearch. AI server is the primary driver across nearly every premium PCB material category.

Will Rubin Ultra (Kyber, 2027+) make this worse->

Yes. Rubin Ultra is projected at approximately 78+ layers on M9 Q-glass (with M10 in qualification), HVLP5 copper foil, and substantially expanded midplane and ConnectX content. The same material categories already constrained in 2026 will be further constrained as Rubin Ultra ramps. Capacity additions in T-glass (Nittobo 3× expansion), HVLP foil and CCL plant equipment do not arrive at scale until 2027-2028, providing relief at the same time demand steps up again.
