4-2-6 The Undisputed Leader in Cloud Motherboards — Gold Circuit Electronics (2368)'s Thick Board Moat

In the world of server PCBs, Gold Circuit Electronics (GCE, 2368.TW) is the undisputed "king."

Whether it's traditional servers, AI servers, or high-end networking switches for cloud data centers, as long as it involves "large-sized, high-layer-count, server" applications, Gold Circuit Electronics is always listed as the First Source (primary supplier) on the hardware lists of all global cloud giants (AWS, Microsoft, Google) and server ODMs (Quanta, Wiwynn).

However, Gold Circuit Electronics' throne was not built overnight. It took twenty years of "solitude" and "purgatory" to forge the formidable moat that leaves competitors in despair today.

🏔️ Chapter One: The Solitary King Who Abandoned the Red Ocean — Steering Clear of the Consumer Electronics Meat Grinder

Rewind a decade or two. What was the most profitable and glamorous sector in Taiwan's PCB industry back then? It was personal computers (PC/NB) and smartphones. As long as you could secure orders from Apple or major smartphone manufacturers, revenue would surge instantly. That was the "golden age" of frantic PCB expansion.

However, Gold Circuit Electronics' management saw through the essence of consumer electronics: "High volume, but extremely short product lifecycles, and perpetually facing brutal price wars from the Red Supply Chain."

Consequently, Gold Circuit Electronics made a strategic decision that seemed extremely solitary at the time, even neglected by the capital market: They proactively abandoned the red ocean of consumer electronics, concentrating all their R&D resources and production capacity on the "enterprise-grade server" and "networking equipment" segments.

Server boards are characterized by: small order volumes, extremely long certification periods (often exceeding a year), and an insane demand for stability (servers must operate 24 hours a day, 365 days a year without shutdown). This is a long road that severely tests patience and capital strength, but it is precisely this focus that laid the ultimate foundation for Gold Circuit Electronics to dominate AI in the future.

☁️ Chapter Two: The CSPs' Exclusive Armorer — "Blood Covenant Bonding" That Starts from the Design Phase

By the era of Intel Purley and Whitley platforms, cloud computing began to explode. At this time, the market's power structure underwent a dramatic transformation: servers were no longer purchased by traditional brand manufacturers like Dell and HP, but by the financially powerful American cloud giants (CSPs: AWS, Microsoft Azure, Google Cloud).

To pursue ultimate performance, these CSPs began to bypass brand manufacturers and directly engage Taiwanese ODMs (white-box server manufacturers) to design motherboards. In this process, Gold Circuit Electronics demonstrated its most formidable commercial weapon: "Blood covenant bonding that starts from the design-in phase."

• Invisible Barrier of Collaborative Development: When AWS or Microsoft engineers develop a new generation of servers, they directly bring Gold Circuit Electronics' R&D team into the meeting room. From the very first circuit design diagram (layout), Gold Circuit Electronics participates, advising clients, "This trace routing here will cause interference," or "The material there must be changed."
• Exorbitant Replacement Costs: Once a server motherboard design is complete, it must undergo rigorous reliability testing (e.g., extreme hot/cold shock, drop tests) for half a year to a year. Once Gold Circuit Electronics' board passes testing and its specifications are locked in, customers simply dare not and are unwilling to switch to a second supplier (Second Source) to save a small amount of money. This is because if switching boards causes server downtime, the CSP loses millions of dollars in cloud service fees per second.

This deep-rooted customer relationship ensures that in the future AI era, no matter how chips change, Gold Circuit Electronics will remain the CSPs' most trusted "exclusive armorer."

🧱 Chapter Three: The Physical Purgatory of Thick Boards — The "Mille-Feuille Cake" of 20-30 Layers

If you ask: Can't other PCB manufacturers also compete for server orders? The answer is: The technology barrier is insurmountable. The "High Layer Count (HLC) lamination process" for server motherboards is the true purgatory of PCB manufacturing.

AI server universal baseboards (UBBs) often reach thicknesses of 20 to 26 layers or more; while high-end 800G switch boards approach 30 layers. This presents three hellish physical challenges:

1. The Curse of Warpage: You can imagine laminating a PCB as baking a 26-layer "mille-feuille cake." These 26 layers include extremely smooth HVLP copper foil and M8-grade PPO resin, which has no tackiness. When this very large, very thick board is fed into a high-temperature, high-pressure laminating machine, the thermal expansion and contraction coefficients of the different materials are completely dissimilar. If the temperature profile control is off by even one degree, or if the hundreds of tons of pressure are slightly unevenly distributed, the board will severely warp like a "wavy potato chip" after it comes out and cools. If the board warps, the GPUs on it will absolutely not solder flat, rendering the entire board unusable.
2. The Hair's Breadth of Registration Misalignment: With 26 layers stacked together, each layer has traces thinner than a human hair. Under hundreds of tons of pressure, the high-temperature molten resin will flow. If there is a lateral offset of a few tens of micrometers between the traces of layer 1 and layer 26, subsequent "laser drilling" or "back drilling" will directly penetrate useful traces, causing an open circuit.
3. Gold Circuit Electronics' Absolute Dominance: In terms of accumulated experience and parameters for laminating "large-area thick boards with 20 or more layers," Gold Circuit Electronics is unrivaled globally. While the Chinese Red Supply Chain or other second-tier Taiwanese manufacturers are still struggling with yields for 16-layer boards, Gold Circuit Electronics has already elevated the yield for 26-layer AI UBBs to a level that can stably contribute super high gross margins. This is a "process moat" built purely through time and discarded boards.

☁️ Chapter Four: The Confidence of AWS's Exclusive Manufacturer — The Profitable Pull-in Wave of Trainium 3

The market spotlight often focuses solely on NVIDIA's GPUs, overlooking the "custom ASIC chip" battlefield that cloud giants (CSPs) are frantically investing in to reduce their reliance on NVIDIA and control their computing power costs. In this arena, Gold Circuit Electronics is the absolute invisible winner.

Particularly within Amazon (AWS)'s supply chain, Gold Circuit Electronics has demonstrated astonishing dominance:

• Strong Outbreak in 2Q26: According to the latest supply chain tracking, AWS's Trainium series servers are expected to experience strong pull-in momentum in the second quarter of 2026. After a transition period in 4Q25 and 1Q26, AWS-related PCB shipments are anticipated to reach 350,000 to 370,000 units in 2Q26, a significant QoQ increase of 33%. Furthermore, 4Q26 is projected to be the peak shipment quarter for the entire year.
• Dual Engines of Volume and Price Growth for the Full Year: Looking at the entirety of 2026, AWS's PCB shipments are expected to grow by 30% YoY, exceeding 1.6 million units. More critically, as specifications upgrade from Trainium 2 to Trainium 3, the average selling price (ASP) of its motherboards will further increase by 15% to 20%.
• Significant Market Share Expansion: As the design of AI ASIC carrier boards becomes increasingly complex, the ranks of PCB suppliers capable of stable delivery are rapidly consolidating. Leveraging its irreplaceable high yield rate in thick board lamination, Gold Circuit Electronics is projected to further strongly increase its market share in AWS projects to an absolutely dominant position of 50% to 60%.

🛡️ Chapter Five: The Invisible Super Booster — PCIe 6 and the Upgrade Dividend for General Servers

Gold Circuit Electronics' most formidable defensive foundation lies in its ability to capture both volume and price growth even from "non-AI general servers."

While AI servers offer powerful computing capabilities, they still require the assistance of general-purpose servers (responsible for storage, data orchestration, and front-end processing). It is expected that from the second quarter of 2026, global general-purpose servers will officially embark on a new round of "PCIe 6.0 platform transition."

• Layer "Inflation" for Two Major Platforms: Intel will transition from the Birch Stream to the Oak Stream platform, and AMD will also introduce its new architecture (Zen 6 Venice). To support the extreme signal transmission speeds of PCIe 6.0, the layer count of general server motherboards will universally increase from the previous 18-22 layers to 20-24 layers (20-24L).
• Material Upgrade and Value Per Unit Jump: Not only will the boards become thicker, but the copper-clad laminate (CCL) material must also upgrade from M6-grade to the more expensive M7 (Ultra Low Loss) grade. This directly leads to a significant increase of over 20% to 30% in the per-unit value of the motherboard for each general-purpose server. For Gold Circuit Electronics (GCE), which holds the leading market share in general server boards globally, this is undoubtedly a super invisible booster that it can steadily capture without competing with others.
