The Macronix Effect will be quite strong for MLCC starting next year Great for Chinese & Taiwanese players If Murata doesn't want to lose this market, then they need to raise CAPEX by a lot

What's happening in the MLCC market First off, MLCC as a whole is a $15B market. MLCCs for servers were a $1.3B market in 2025 ($600m for AI servers, $700m for general servers) The AI server MLCC market is growing at 80%+ CAGR, and the general server MLCC market will also accelerate due to agentic AI increasing CPU demand (around 30%-40% CAGR) We will see negative growth in the smartphone/mobile MLCC market for at least 2026-27. Humanoids are another future high-growth market for MLCCs Book-to-bill ratio for most MLCC suppliers is over 1 now Reasons for price hikes- High Nickel & Silver are affecting all segments There is a supply-demand mismatch in the high-end (high capacitance, high voltage) segment, which is used in autos & servers High-end MLCC lead time is over 20 weeks Spot/distributor prices have increased by 20%-40% for low capacitance & consumer device MLCCs due to hoarding and double booking, especially in China OEM contracts have not seen large price hikes yet What's happening now: Rapid capacity expansion happening across the industry Murata expects blended ASP prices to remain flat (ASP going down in consumer electronics, expansion in AI server market) Tier 1 players like Murata, Taiyo Yuden, SEMCO building capacity to serve AI server MLCC market This will create opportunities for Tier 2/3 and Chinese suppliers to expand in the mid to low end market (Macronix effect) Future: MLCC production equiment & raw materials suppliers will be the biggest beneficiary of this CAPEX boom MLCC producer stocks have performed well, and it is finally spilling to raw material/equipment producers I expect them to outperform MLCC producers now

@TsaiKen57383 不會 因為low dk 以上的利潤更好,他中國還有E的產能~目前E 系列的布毛利率也是往LOW DK GEN1 靠攏

@pcbanalysis 這樣富喬把產品線從e glass往low dk&t glass移反而會是反效果?

Driven by the non-stop price hikes in E-glass (+60% to 90% YTD), Taiwan's Glotech has hit record revenues, and Nan Ya keeps growing its revenue month-over-month. If you want to track the actual performance and profit conversion of the E-glass rally, looking at these two companies is your most direct bet

In terms of the resin matrix, the formulation will transition from M9's PPO/Hydrocarbon blend to M10's pure Hydrocarbon resin. Furthermore, regarding the reinforcement fabric, while M9 predominantly utilizes Gen 1 Quartz fabric, M10 is shifting decisively toward Gen 2 Quartz fabric.

Jim X@Jim_oldcity8·
@pcbanalysis Thanks for sharing. Can I ask what’s the difference between M9/M10 solution? Since they are both adopted Q glass, I guess the changes are on glass fiber or else to achieve the required electrical performance?

Our current thesis remains unchanged: PTFE is merely a secondary, non-mainstream solution that is highly unlikely to achieve commercial mass production. Instead, the M10Q configuration remains the clear preferred choice, primarily because it offers a broader pool of qualified suppliers and commands strong deployment support from tier-1 PCB fabricators.

@qeksersvv33 因為有些供應商想要打進去,自然去推了其他供應商沒有的方案,也就是這個PTFE的方案,不管是生益還是台虹都是這樣。 至於後段製程問題很多...板廠都知道..對於PTFE的評價不高...評價高的講法,大多是材料商自己講的

@pcbanalysis 請教一下 混壓的可能性?M10可行嗎?我記得M9電性已經到極限了。PTFE無法商業化,2-3年後有可能嗎?若沒可能怎有廠商研發這種東西?他們不知道這東西在後段製程問題很多?謝謝

M9之前採用PPO系列樹酯,但搭配Q布方案適用於LPU/主板等級,在正交背板上仍不足,供應商改採用CH系列的樹酯搭配Q布來解決這個問題。 PTFE 性能很好沒錯,但配方這東西不是性能好就一定要用,還要考量供應商能力、板廠能力、設備商能力,我不敢說2-3年後有無可能,作夢/作文都得說2-3年後有可能(光相關的敘事如此)

Nobody is asking who makes the <$1 multi-layer ceramic capacitor (MLCC) that keeps voltage stable across every chip in the rack, that every AI server needs tens of thousands of, that has long extended lead times, and going through an unprecedented price hike. AI server MLCC demand is growing ~5x by CY27. New production lines take 2 years to build. The bottleneck is spreading.

理想是這樣...要用美系的..就接受比較高的價格.. 亞洲系的板廠,配合度還是好的 這是現實問題

PCB是所有電子產品的核心基板,卻幾乎隱形存在。在 AI 熱潮中,Nvidia 等大廠的高階 AI 伺服器電路板,絕大部分由中國製造,全球約 60% PCB 產能來自中國,美國本土市占率已從過去 30% 暴跌至僅 4%,形成嚴重國家安全風險。 中國製 PCB 可能被植入惡意元件,導致資料外洩、系統效能降低,甚至飛彈導引失靈。美國國防部因此高度警覺,要求關鍵採購必須來自國內。國防官員警告,這是最容易被破壞的供應鏈環節。 為解決危機,美國國會兩黨正推動《保護電路板與基板法案》,提供選擇美國製 PCB 的企業 25% 稅務抵免,並擬撥款 30 億美元補助本土廠商。 $TTM Technologies 與 Sanmina 這兩家美國上市 PCB 廠商,正加速擴張國內產能:TTM 將在紐約州與威斯康辛州新建大型工廠,完工後美國將擁有 18 座廠。 AI 需求爆炸性成長,導致 PCB 價格大漲 5%~40%,TTM 執行長表示「晶片不會漂浮」,所有先進晶片都必須靠高階 PCB 才能運作。儘管 Nvidia 已透過 X 光與 AI 檢測降低風險,但供應鏈過度依賴中國仍被視為重大漏洞。 在美中科技戰升級之際,此議題凸顯美國重建關鍵電子供應鏈的急迫性。專家呼籲,唯有發展具競爭力的本土 PCB 產業,才能確保 AI 與國防科技的長期安全。 cnbc.com/2026/06/03/ben…

No, people are misinterpreting $AVGO CEO comments. Demand is insatiable in general, but hyperscalers don't want to be bottlenecked, so it's inevitable $GOOGL and others multi-source. Broadcom's bottom line keeps increasing, but because the pie keeps increasing, Mediatek, Marvell, AlChip, and all the others will benefit too. But the latter much more than Broadcom.

While Nittobo is undeniably the global leader in conventional electronic-grade glass fabric, its market share in the Low-DK Gen 2 segment is far less dominant than the consensus assumes, driven by the following structural factors: 1. Client Alignment: Nittobo’s primary Copper Clad Laminate (CCL) clients are concentrated among Doosan, Panasonic, and TUC. 2. Supply Chain Disconnect: The leading suppliers for the dominant GPU camps are currently Doosan, Shengyi Technology , and EMC , while the ASIC camps are primarily anchored by EMC, Panasonic, and TUC. Crucially, EMC, which commands the industry's largest capacity, is not a primary customer of Nittobo. Meanwhile, Shengyi Technology relies heavily on CPIC . 3. Upstream Yarn Sourcing Dynamics: In the transition to Low-DK Gen 2, Nittobo does not supply its premium glass yarn to independent weavers like Asahi Kasei. Consequently, other weavers must source their yarn from the US, Taiwan, and China. This is significant because Asahi remains a critical, foundational supplier to EMC. 4. Penetration Bottlenecks for NER and NEZ: The adoption and market penetration of Nittobo’s next-gen NER and NEZ products are fundamentally tied to the market share trajectories of Doosan, Panasonic, and TUC. However, the current reality is that the tier-1 CCL vendors holding the largest capacity and highest market shares are simply not deploying Nittobo’s solutions. Market Perspective on Pricing Power:Recently, I have been asked why my stance on Nittobo’s pricing leverage is so conservative. To clarify: while Nittobo can easily initiate price hikes in the Low-CTE segment where it holds undisputed dominance, it has no solid foundation to command price increases in the Low-DK Gen 2 market, simply because its core downstream customers lack the market share dominance to pass those costs along

@Salehaldin0b AT&S isn't even an option on NVIDIA's radar. As for SEMCO, although they are already in NVIDIA's general supply chain, they still haven't managed to break into the CPU substrate side yet.
