Introdução: The Foundation in the Storm’s Eye
Beneath the spotlight on the semiconductor industry, o Placa de circuito impresso (PCB) has long played the role of a silent, foundational pillar. No entanto, em 2025, a raw material price storm, led by gold and copper-clad laminates (Ccl), has thrust PCBs to the forefront of supply chain cost pressures. This storm is no accident; it is the intense collision between exponential demand growth from AI infrastructure expansion and limited supply capacity. This article provides a professional analysis of the PCB industry’s cost challenges and underlying drivers, revealing how profound technological transformation is enabling a leap in value amidst the crisis. It offers critical insights for companies seeking reliable Fornecedores de PCB e de alta qualidade PCBA serviços.
EU. Cost Deconstruction: The “Gold and Silver” Straws Breaking the Camel’s Back
The raw material cost structure of a PCB is complex, but gold and copper-clad laminates are undoubtedly the two heaviest “weighted stocks.” According to analysis from the authoritative industry firm Prismark, in a typical multilayer PCB for servers, CCL can account for 30%-40% of the cost, while precious metals like gold used in plating and surface finishes (por exemplo, CONCORDAR) can account for 8%-15%. Junto, they approach half of the total material cost. This can be simplified as:
PCB Raw Material Cost ≈ (CCL Cost × Share) + (Precious Metal Cost × Share) + (Other Material Costs)

1. Ouro: More Than a Shiny Finish
Gold in high-end PCB is primarily used for surface finishes on critical connections to ensure superior conductivity, oxidation resistance, and solderability. The price of potassium gold cyanide (sais de ouro), por exemplo, has become an industry barometer. Data from a major Korean Fabricante de placas de circuito impresso reveals a staggering trajectory: from approximately 50,000 KRW/gram in 2023 para 99,000 KRW/gram in Q3 2025—a near 100% increase. This directly raises the manufacturing cost for PCBs HDI and IC substrates using processes like ENIG (Ouro de imersão em níquel eletrolítico). For clients requiring high-volume Montagem PCBA, this cost transfer is significant.
2. Copper-Clad Laminates: The Direct Conduit of AI Demand
As the core dielectric carrying circuit patterns, the performance of CCL directly determines the final PCB’s integridade do sinal, Gerenciamento térmico, e confiabilidade. Servidores de AI, high-speed switches, e AI accelerator cards impose near-demanding requirements for data throughput and signal loss, driving explosive demand for high-speed/high-frequency, ultra-low loss (por exemplo, Ultra Low Loss, Very Low Loss grades) laminates.
Feedback from top-tier manufacturers like Samsung Electro-Mechanics—reporting a 10%-15% year-over-year procurement cost increase in Q3—epitomizes this structural supply tension. This is especially true for high-performance laminates used in AI server motherboards e GPU accelerator card PCBs.
II. Deep-Seated Drivers: The AI Frenzy Reshaping the PCB Demand Map
Rising raw material costs are the surface symptom; the core engine is global digital and intelligent transformation, specifically the arms race in AI computing infrastructure.
1. Role Evolution: From “Connector” to “System-Critical Component”
Tradicionalmente, PCB were viewed as mechanical supports and electrical connection platforms for components. In the AI era, this role has fundamentally changed. Next-generation architectures, exemplified by platforms like NVIDIA’s Rubin, pursue extremely high internal interconnect bandwidth and density, making high-layer-count PCB (tipicamente 22+ camadas) e any-layer HDI technology standard. Every trace on the PCB affects data latency and power consumption; its design and manufacturing precision directly impact the synergistic efficiency between CPUs/GPUs, memória, and accelerators. Industry analysis indicates that an AI server motherboard’s value is multiples that of a standard server, com seu PCB portion seeing corresponding increases in technical content and price.
2. Exponential Rise in Demand Specifications
AI training and inference generate specific and stringent PCB requirements:
-
Increased Layer Count: To accommodate more complex power delivery networks and more signal layers, AI server motherboard layer counts are moving toward 30 layers and beyond.
-
Material Upgrades: Data rates moving from 224Gbps and beyond are driving demand for M6, M7 grade ultra-low loss laminates (Df as low as 0.0015).
-
Tamanho & Integração: Larger board sizes to integrate more compute units, and advanced processes like embedded component PCB to enhance integration and performance.
De acordo com o IPC (Association Connecting Electronics Industries) 2025 outlook report, the global high-end PCB market for data centers and AI infrastructure is projected to grow at a CAGR of over 14% de 2024 para 2028, far exceeding the industry average.
