伺服器組裝廠 8 月營收展現驚人爆發力，緯創單月合併營收達 4,600.65 億元，年增率高達 166.46%，前 8 月累計營收跨越 2.51 兆元；廣達訂單能見度更已排至 2028 年，全年每股盈餘預估挑戰 28.49 元。然而，在 1,000 億出貨規模的表象背後，供應鏈底層正遭遇劇烈的成本通膨夾擊。組裝廠雖然身處出貨爆發期，但關鍵零組件價格飆漲與散熱規格大改，正無情侵蝕代工毛利。這場由上游原料暴漲所引發的成本暗湧，考驗著代工體系能否將通膨完全轉嫁給北美雲端巨頭，更將直接決定硬體出貨熱潮能否轉化為實質獲利。Taiwanese server assemblers posted blistering revenue figures for August, with Wistron delivering consolidated monthly sales of NT$460.065 billion—a 166.46% year-over-year surge that pushed its eight-month total past NT$2.51 trillion—while Quanta's order visibility stretched into 2028, setting the stage for full-year earnings per share to challenge NT$28.49. Yet behind this hundred-billion-dollar shipment boom, the supply chain's foundation is being squeezed by acute cost inflation. Even as assemblers ride unprecedented unit demand, sharp price increases for critical components alongside sweeping thermal architecture overhauls are relentlessly eroding contract manufacturing margins. This upstream pricing surge is testing whether original design manufacturers can pass inflation entirely along to North American cloud hyperscalers—a dynamic that will determine whether top-line AI hardware growth translates into tangible bottom-line profits.

記憶體報價倍增侵蝕代工毛利Surging Memory Quotes Squeeze Manufacturing Margins

第一重實質衝擊來自存儲與主動元件的全面價格重定。市場數據顯示，LPDDR5X成本漲幅高達 4 倍，NAND Flash漲幅達到 3 倍，鎧俠近期也再度將報價調升約 10%；在通用伺服器領域，下半年DDR4 合約價亦面臨逾 20%的調漲幅度。這種全方位的記憶體通膨，直接重擊組裝代工廠長期維持在低個位數的毛利率底線。龐大的採購支出不僅壓縮獲利空間，更極度消耗營運周轉資金，迫使華碩等品牌廠必須透過海外發行 15 億美元可轉債來充實流動性，顯示上游物料成本膨脹的壓力，已迅速擴散至整體代工供應鏈的財務層面。The initial cost shock is stemming from broad-based repricing across memory and active components. Industry data shows LPDDR5X costs have quadrupled and NAND Flash prices have tripled, while Kioxia recently pushed through an additional price hike of roughly 10%. In general-purpose enterprise servers, second-half contract prices for DDR4 face increases topping 20%. This sweeping memory inflation strikes directly at assemblers' gross margins, which have historically hovered in the low single digits. Burgeoning component outlays are not only compressing margins, but also tying up substantial working capital. This liquidity strain prompted branded OEMs like ASUS to issue $1.5 billion in overseas convertible bonds to shore up cash reserves, underscoring how upstream component inflation is testing balance sheets across the hardware ecosystem.

水冷與高壓架構推升系統物料成本Liquid Cooling and High-Voltage Architectures Inflate System BOMs

零組件報價飆漲之外，散熱與供電架構的技術代際躍遷正顯著推高系統製造成本。新一代AI機櫃功耗突破百萬瓦大關，推動 800V高壓直流架構與水冷模組由選配轉為標準配置。關鍵零組件龍頭已進入大規模擴產期，奇鋐水冷板月產能於下半年推進至 100 萬組、分歧管提升至 7,000 單位，並投入鉅資擴充越南生產基地；台達電水冷散熱占營收比重亦從 9%爬升至 12%。電源供應與散熱次系統單價顯著翻倍，直接加劇整機BOM表的膨脹速度，未能取得關鍵專利與技術規格的二線組裝業者，面臨更嚴峻的製造成本擠壓。Beyond component pricing, generational transitions in thermal and power delivery architectures are driving up system-level manufacturing costs. Next-generation AI server racks exceed one megawatt of power consumption, turning 800V high-voltage direct current (HVDC) power architectures and liquid cooling modules from optional upgrades into standard requirements. Leading component suppliers are in the midst of aggressive capacity expansions: Auras Technology is scaling monthly cold plate capacity to 1 million units and manifolds to 7,000 units in the second half, backed by heavy capital outlays in Vietnam, while Delta Electronics has seen liquid cooling expand from 9% to 12% of its revenue mix. Doubling sub-system unit prices for power and cooling is accelerating total bill-of-materials (BOM) inflation, disproportionately squeezing second-tier assemblers that lack scale, critical IP, and specialized assembly capabilities.

面板級封裝外溢難掩製程良率隱憂Panel-Level Packaging Spillover Encounters Process Yield Hurdles

硬體產能擴張的第三道屏障在於先進封裝的結構性短缺。台積電以 72.5%的晶圓代工市占率維持主導地位，先進製程藍圖雖已推進，但前段封裝產能的持續緊繃，迫使外溢需求轉向方形面板級封裝與專業封測廠。日月光投控全年度資本支出推升至 105 億美元以承接外溢訂單，群創第 1 代晶圓級製程每月晶片需求亦達到 6,000 萬顆規模。然而，封裝基板由圓形晶圓轉為方形面板的製程轉換中，應力控制與基板翹曲問題尚未完全排除，技術良率的不確定性成為左右後續出貨節奏與量產成本的最大變數。The third structural constraint on volume delivery remains advanced packaging capacity. While TSMC retains dominance with a 72.5% share of the foundry market and continues to advance its process roadmap, tight front-end advanced packaging capacity has redirected spillover demand toward rectangular panel-level packaging (PLP) and outsourced semiconductor assembly and test (OSAT) providers. ASE Technology Holding has lifted its full-year capital expenditure budget to $10.5 billion to capture these overflow orders, while Innolux's first-generation wafer-level process is fielding monthly demand of 60 million chips. However, the migration from circular wafers to rectangular glass and resin panels introduces unresolved warpage and mechanical stress dynamics, leaving yield uncertainty as the primary swing factor dictating shipping cadence and commercial volume economics.

硬體組裝族群當前的出貨動能，實質上建立在雲端服務商無上限擴張資本支出的平衡上。本刊判斷，營收規模的等比放大已不足以保證獲利水準，供應鏈的核心考驗在於毛利能否抵禦零組件通膨侵蝕。接下來需密切觀察組裝代工廠在季報中的營業利益率走勢，以及終端客戶對硬體漲價轉嫁的實質承受意願。Current shipping momentum among hardware assemblers hinges on cloud service providers maintaining open-ended capital expenditure expansion. In this publication's assessment, scaling revenue alone no longer guarantees profitability; the true litmus test for the supply chain is whether gross margins can withstand component-cost inflation. Looking ahead, investors must scrutinize operating margin trajectories in upcoming quarterly filings, alongside hyperscalers' willingness to absorb higher hardware sticker prices.
