The pursuit of wealth has shifted its focus to the PCB sector. A wave of price increases in upstream materials, driven by AI computing power demand, is currently sweeping through the industry. Key material suppliers for items like copper-clad laminates, electronic glass fabric, and high-end copper foil have issued price hike notices, signaling a period of robust industry prosperity.
However, examining the market activity from a recent Friday reveals a divergence: while fiberglass and glass substrate stocks reached new highs, PCB manufacturing stocks saw significant declines. Why has this涨价 logic not been uniformly applied across the board?
Let's analyze what is happening in the upstream and midstream segments of the PCB industry to understand where capital is flowing and where it is retreating during this涨价 wave.
Understanding PCB's 'Semiconductorization'
Historically, many viewed PCBs merely as the green 'plastic boards' inside electronics, not considering them high-tech. The AI era has fundamentally颠覆 this perception.
Taking the即将量产的 Nvidia Vera Rubin platform as an example, the value of the PCB per rack has surged from $35,100 in the previous generation to $116,700, representing a year-over-year increase of 233%.
This signifies that the number of PCB layers has skyrocketed from the traditional dozen or so layers to 44 layers or even over 78 layers, with the line width and spacing approaching the精度 of IC packaging substrates.
This non-linear升级 in process difficulty and production capacity barriers has propelled the entire PCB industry toward comprehensive 'semiconductorization'.
Upstream Materials: Supply Rigidity Meets Demand Surge, The Undisputed 'Inflation King'
In this AI-driven market cycle, the upstream materials segment has been the first to reap the most significant price红利, capitalizing fully on 'price elasticity'. The core logic is straightforward: global demand is surging, but upstream capacity expansion is severely constrained by technology, resources, and equipment limitations due to supply rigidity.
Specifically, the PCB upstream consists of the following key segments and 'capital-intensive beasts':
1. Copper-Clad Laminate (CCL): The first wave's inflation bellwether. CCL is the most critical base material for manufacturing PCBs. The global leader in rigid CCL, Kingboard Laminates, has already raised prices five times within a certain period. The mainstream FR-4 CCL has seen cumulative涨幅 exceeding 55% year-to-date, while prepreg has surged over 70%. Furthermore, the调价周期 is shortening, and the magnitude of单次涨幅 is increasing, highlighting the疯狂 of downstream抢货.
2. Copper Foil & Electronic Glass Fabric: The幕后推手 of cost resonance. The significant涨价 in CCL is due to its three main materials—copper foil, glass fabric, and resin—accounting for over 85% of its cost.
Particularly for high-end HVLP copper foil dedicated to AI, the supply gap is projected to be between 28% to 39% for the 2026-2028 period. The urgency is such that Nvidia has reportedly bypassed intermediaries to directly secure产能 with copper foil manufacturers.
Meanwhile, the expansion of high-end electronic glass fabric production is bottlenecked by Japanese Toyota weaving machine equipment, with orders backlogged until the end of 2028, making the equipment virtually unavailable regardless of price.
3. Drill Bits & Tungsten Rods: The 'Dark Horse' with consumption soaring hundreds of times. As PCB layer counts increase and孔径变小, micro-drill bits made from ultra-fine grain tungsten carbide are required for drilling.
Following China's implementation of export controls on tungsten-related items, Japanese high-end drill bit giants reliant on Chinese imports face原料断供, leading them to announce price increases ranging from 5% to as high as 300%.
Even more striking, the drill bit consumption for AI servers is tens to hundreds of times that of traditional servers. Because the substrate material is so hard, drill bit寿命骤降, transforming them from low-value consumables into a highly profitable主线.
4. High-End Equipment: The ultimate '拦路虎' on the expansion path. Beyond materials, there is a severe shortage of high-end mechanical drilling machines (e.g., from Schmoll) and high-precision presses (e.g., from Bürkle), leading to systematically延长 delivery cycles.
This means that even with ample订单 and cash, PCB manufacturers cannot release capacity without the equipment, further推高 the inflationary壁垒 within the industry chain.
Midstream PCB Manufacturers: Domestic Firms Hold Scarce Capacity, Anticipating 'Performance Inflection' in Q3
If the upstream segment profits from 'scarcity and抢先涨价', then the midstream PCB manufacturing segment profits from 'hardcore technology and业绩兑现'.
The focus in the midstream segment is very clear and can be summarized in four words: domestic advantage. Many are unaware that Mainland China possesses the core global capacity for high-end computing PCB production, accounting for 56% of the world's PCB output value in a recent year.
Whether for the Nvidia主线 or the ASIC阵营 including Google and Broadcom, their most critical, highest-tier server boards and orthogonal backplanes are predominantly mass-produced by leading domestic Chinese manufacturers like Shengyi and Wus.
Why must high-tech giants turn to these leading domestic板厂? Because AI PCBs are difficult to manufacture. With layers approaching a hundred and line width/spacing nearing semiconductor chip levels, a slight良率 drop at any single环节 can render an entire board worth tens of thousands of dollars报废.
In the current intense AI arms race, the strategic importance of 'stable mass production with high良率' far outweighs 'cost-effectiveness'.
Although the疯狂涨价 of upstream materials in the first half of the year imposed certain cost压力 on midstream manufacturers, reports clearly indicate that a definitive业绩爆发拐点 is expected in the third quarter of a given year.
Three reasons support this:
1. Successful Price Transmission: Starting in the second half, manufacturers are gradually passing on the涨价 costs from upstream to end大客户 through协商顺价, leading to盈利修复.
2. Ramp-up of New Platform Production: New computing platforms like Nvidia's Vera Rubin are集中放量 in the second half, unleashing a wave of high-value, high-end orders that will keep leading板厂 at full capacity.
3. Resonance with Traditional Peak Season: The third quarter is traditionally a peak season for consumer electronics. Coupled with sustained AI computing demand拉货,订单景气度 is expected to surge sequentially.
Choosing Between the Two Main Lines? Timing is Key
After reviewing the logic for upstream and midstream, we find they are not mutually exclusive but rather form a perfect 'relay race'.
Price signals always propagate from upstream to downstream. At the current stage, the upstream segment,凭借 the hardest constraint of minimal supply elasticity, is the first to convert景气度 into price and profit gains, representing the弹性主线 for the entire industry chain.
Around the third quarter, as顺价落地 and the shipment wave for the Rubin platform materializes, capital is expected to gradually shift towards the业绩兑现 of midstream PCB manufacturers.
In summary, the era of 'capacity as壁垒' characteristic of semiconductorization has arrived. Whether one focuses on the爆发力 of material inflation or看好 the high-end稀缺性 of domestic manufacturers, this AI-driven high景气周期 across the entire PCB industry chain warrants long-term复盘 and关注.
