Cadence Sigrity 高速信号互连|电源|完整性仿真 导语：<\/strong>7月3日晚间，全球PCB营收第一的鹏鼎控股（002938）发布2026年度定增预案，拟募资不超过96亿元，全额投向淮安庆鼎AI服务器与高速光模块高阶HDI项目。这一动作标志着PCB行业龙头正式将战略重心从消费电子转向AI算力硬件，行业竞争格局加速重塑。<\/p> 一、96亿定增全部投向高端算力产线<\/strong><\/p> 据《证券时报》（http:\/\/m.toutiao.com\/group\/7658276185528369664\/）报道，本次定增项目计划总投资127.3亿元，将新建智能化生产厂房，引进钻孔、压合、镀铜、mSAP精细线路等自动化高端设备，建成后新增65.56万平方米高阶HDI年产能，专攻AI服务器与高速光模块配套高精密积层板。项目已完成投资备案，环评、能评手续有序推进。<\/p> 鹏鼎控股表示，公司自2017年至2025年连续九年位居全球PCB营收第一，已构建覆盖FPC、高阶HDI、SLP、高多层刚性板的全品类产品矩阵，形成\"深圳、淮安、秦皇岛国内基地+泰国海外园区\"的全球化产能布局。2025年公司购建固定资产等支付的现金达66.3亿元，同比大幅增长133%。单纯依靠自有资金和银行贷款已难以支撑大规模高阶HDI扩产，本次定增是落实战略的关键资本抓手。<\/p> 二、AI算力重塑PCB增长逻辑<\/strong><\/p> 据花旗证券2026年6月研报，2026至2028年全球AI领域PCB市场规模有望达到1520亿元、3070亿元、5620亿元，年增速分别为86%、102%、83%。AI服务器对PCB的层数、材料、工艺要求远超传统产品——英伟达Rubin架构AI服务器正交背板可达78层，单机PCB价值量飙升至2800至3500元，是传统服务器的3至5倍。<\/p> 鹏鼎控股已开发支持GPU模块的高阶HDI、内埋元件等创新技术，高阶HDI产品成功打入AI服务器市场并通过云服务厂商认证。在高速光模块领域，SLP产品已切入800G\/1.6T高端市场并实现量产出货，3.2T产品已进入研发阶段。<\/p> 三、行业观察：扩产不等于护城河<\/strong><\/p> 值得注意的是，鹏鼎控股2025年净利润增速趋近于零，受原材料涨价与新产线折旧双重拖累。这也折射出行业的一个核心矛盾：大规模扩产本身并非护城河，良率控制、工艺落地、产能爬坡的核心技术与人才，才是企业真正的竞争壁垒。<\/p> 当前PCB全行业头部企业扩产如火如荼——鹏鼎127亿、胜宏科技200亿、沪电股份超170亿、深南电路48.82亿元投资计划密集落地，mSAP工艺、高多层板制程等高端技术人才缺口持续扩大，未来1至2年行业专业人才将持续供不应求。<\/p> 四、延伸展望：寡头化格局加速成型<\/strong><\/p> 业内人士指出，高端PCB属于资本、技术、客户三重密集行业。本轮大规模扩产结束后，中小厂商在产能和技术上的劣势将彻底凸显，行业集中度快速提升，下半年有望正式进入寡头竞争时代。具备技术壁垒与产能优势的头部企业，将持续受益于行业提价与份额提升的双重红利。<\/p> 关键词：<\/strong>鹏鼎控股、定增96亿、AI服务器PCB、高阶HDI、mSAP工艺、算力硬件、光模块<\/p>

英伟达Rubin架构改写PCB价值坐标 单机价值量飙升至传统服务器3倍以上<\/p> 导语：<\/strong>2026年下半年，英伟达新一代Vera Rubin平台将正式量产出货。这一架构不仅在芯片算力上实现飞跃，更从底层硬件设计层面彻底改写了PCB的价值坐标——从被动连接件跃升为芯片最后一层封装载体，单机PCB价值量飙升至传统服务器的3倍以上，行业格局正在经历根本性重塑。<\/p> 一、Rubin架构对PCB的颠覆性需求<\/strong><\/p> 据凤凰网财经（https:\/\/finance.ifeng.com\/c\/8uQTonTGOn0）报道，随着英伟达Hopper迭代至Rubin\/Rubin Ultra架构，叠加谷歌TPU、AMD MI系列ASIC芯片算力密度指数级提升，AI服务器对PCB提出了全新的严苛标准：需要支撑112G\/224G高速SerDes互联，介质损耗控制至Df≤0.002，线宽线距精细度缩小至30μm以内，同时采用密度远超传统产品的盲埋孔、叠孔堆叠结构。<\/p> 产品规格方面出现明显升级：算力主板、加速卡基板层数普遍提升至18-30层超高多层；整机正交高速背板方案层数可达70-80层，生产端必须配套6阶及以上高阶HDI或mSAP半加成精密工艺。传统服务器PCB仅8-16层，单台价值约650元；而Rubin架构AI服务器的正交背板可达78层，单机PCB价值量飙升至2800-3500元，单机柜PCB价值突破80万元。<\/p> 二、CoWoP方案：PCB从连接件到封装载体的根本跃迁<\/strong><\/p> 更具里程碑意义的是，国金证券2026年5月深度报告提出了一个标志性判断：CoWoP（Chip-on-Wafer-on-PCB）方案正在打破PCB与封装基板的边界。该方案去掉传统CoWoS中的ABF封装基板与BGA焊球，将硅中介层与GPU\/HBM直接安装在强化型Platform PCB上——这意味着强化PCB要承担原属封装基板的电气与机械功能，对板材均匀性、翘曲控制、超低损耗介质提出近乎载板级要求。<\/p> 国金证券分析师在报告中指出：\"这是PCB与封装基板边界消失的标志性事件，标志着PCB从被动连接件向主动封装载体的根本性跃迁。\"虽然量产时间表还存在不确定性，但高端PCB\"承接更多功能\"已是行业共识。这一趋势意味着，未来PCB厂商需要具备传统上与封装基板厂商竞争的技术能力，行业壁垒进一步抬高。<\/p> 三、市场数据印证：高端板增速碾压低端品类<\/strong><\/p> Prismark披露的数据清晰呈现了这种结构性变化：2025年全球PCB总产值预计增长15.8%至851.52亿美元，但内部分化极端——18层及以上超高多层板产值增速高达72.8%；高阶HDI增速26%；而单\/双面板、4-6层常规硬板增速仅约6.2%。<\/p> IDC预测，2024-2029年全球服务器市场年均复合增长率将达18.8%，其中加速型服务器支出年均增速达20%以上。以加速型x86为例，2024年全球支出为1130亿美元，预计至2029年将增至3260亿美元，CAGR高达23.7%。这意味着Rubin及后续架构对高端PCB的拉动效应将持续至少5年。<\/p> 四、延伸展望：PCB行业价值体系正在重构<\/strong><\/p> 英伟达Rubin架构的量产不仅是一次产品迭代，更是PCB行业价值体系的重构。当PCB从\"电子之母\"的连接件角色，跃升为算力芯片的核心封装载体，整个行业的竞争规则、技术门槛和利润分布都将发生根本性变化。具备超高层板量产能力、先进封装基板技术和上游材料配套能力的头部企业，将在这场价值重构中占据最有利的位置。而那些仍停留在4-6层普通硬板赛道的厂商，则面临被时代淘汰的风险。<\/p> 关键词：<\/strong>英伟达Rubin、PCB价值重构、CoWoP、超高多层板、AI服务器、封装基板、高速SerDes<\/p> 大族数控披露PCB背钻加工新专利 钻孔设备技术迭代加速高端制造升级<\/p> 导语：<\/strong>7月1日，国家知识产权局公示信息显示，大族数控（301200）一项《电路板的背钻加工方法、装置及系统》发明专利于6月30日完成公开。这一专利聚焦PCB高层板孔位加工精度优化，标志着国内PCB钻孔设备技术正进入密集创新期，为AI服务器高多层板制造提供关键工艺支撑。<\/p> 一、专利解读：背钻加工精度再升级<\/strong><\/p> 据捷配PCB（https:\/\/www.jiepei.com\/design\/pcb-news\/）报道，大族数控本次公开的发明专利涉及一种全新的电路板背钻加工方法及系统。背钻是PCB制造中的关键工序，用于去除多层板中多余的stub（残桩），以确保高速信号传输的完整性。随着AI服务器PCB层数从传统8-16层飙升至28-78层，背钻精度要求呈几何级提升——任何微小的深度偏差都可能导致信号反射、阻抗不匹配，直接影响112G\/224G高速SerDes互联的可靠性。<\/p> 大族数控的新一代背钻方案通过优化加工路径规划和深度控制算法，显著提升了孔位加工精度，同时降低了生产成本。这对于当前AI高多层板产能紧张、交期延长至2-3个月的行业现状，具有重要的工艺降本和效率提升意义。<\/p> 二、行业背景：钻孔设备成AI时代PCB制造核心环节<\/strong><\/p> 钻孔是PCB层间互连的核心工序，其精度和效率直接决定了高多层板的良率和产能。AI服务器PCB的钻孔密度从传统服务器的100-200孔\/cm²飙升至300-500孔\/cm²，钻孔深度控制精度要求从±50μm提升至±15μm，对设备性能提出了前所未有的挑战。<\/p> 与此同时，AI服务器PCB对钻针的消耗量也是传统服务器的5-10倍。单支钻针在AI高层板上的寿命仅500-800孔（传统板为2000-3000孔），钻针价值占比从传统的约1%提升至3%-5%。这意味着钻孔设备与耗材已成为AI时代PCB制造中成本和技术含量双重提升的核心环节。<\/p> 据行业数据，PCB钻孔设备技术持续迭代，背钻、微孔相关创新专利在2026年上半年密集公示落地，反映出国内设备厂商正在加速追赶海外龙头的技术差距。<\/p> 三、产业格局：国产设备替代进入加速期<\/strong><\/p> 全球PCB钻孔设备市场长期被日本、瑞士企业主导，日立、维亚机械、Schmoll等品牌占据高端市场主要份额。但近年来，以大族数控、大族激光为代表的国产厂商在技术突破上取得了显著进展，在高多层板背钻、微孔加工等关键领域逐步缩小与国际水平的差距。<\/p> 值得关注的是，钻孔设备的技术进步与上游钻针材料的革新形成协同效应。随着日企住友电工宣布9月永久关停PCB专用钨棒产线，日系钻针供给收缩，国内鼎泰高科、金洲精工等钻针龙头迎来市场份额转移窗口，设备与耗材的国产化正在形成良性闭环。<\/p> 四、延伸展望：设备国产化是高端PCB自主可控的关键一环<\/strong><\/p> 在国内PCB龙头企业纷纷投入数百亿扩产高端产能的大背景下，制造设备的自主可控显得尤为关键。当前国内PCB扩产资金几乎全部投向AI服务器超高多层板、高阶HDI和IC载板，对配套设备的精度、效率和稳定性提出了更高要求。背钻加工等核心工艺的设备国产化率提升，将有效降低高端PCB的制造成本，缩短交付周期，增强国内产业链的整体竞争力。<\/p>
