很多电子设计的新手或者大学生毕业会有这样的迷茫：学校教的东西很通常是理论，动手实践操作可能不是很重要，初入岗位的时候就完全相反了，实践操作能力需要摆在第一位，但是这些实践操作能力又如何去学呢，自学的话效率低不说，还不知道如何下手。<\/p>

针对市面上这种情况，凡亿教育作为电子设计在线教育领军者，我们适时推出此套全流程的电子设计实战视频，满足学员的学习需求。<\/p>

本套教程采用全新版本的 Altium Designer 26来分阶段讲解，从创建原理图库、原理图、PCB库到PCB设计的布局布线，全流程给大家直播讲解和交流。每个器件是怎么画的？怎么摆放的？每一根线怎么拉线？哪些是电源线？哪些是信号线？<\/b>这些都会一个一个的详细讲解，新手一般看一遍就能够自己动手了。从无到有整个环节都说得清清楚楚，这样作为新手才能够真正学到东西。<\/p>

本课程定位主要是入门，采用“项目驱动+手把手教学”的模式。<\/p>

通过采用全新的Altium Designer 26 EDA工具软件，设计一个大学生智能车竞赛中经常用到的电机驱动电路板，产品不是很复杂，\n但我们基于一个电子产品开发的整个流程来进行讲解：原理图的器件选型与设计到PCB布局与布线的全流程，涵盖元元器件的选型、电路的搭建、PCB工程搭建、PCB的导入、PCB布局布线等核心环节，同步融入生产文件输出等工程化设计要点，每一个环节给学员进行细致的讲解和实操演示，过程中也会涉及一些元器件的基本特性与PCB设计的常用概念，能够对入门的学员的基础做一个补充，卡点式教学，力求新手听完就能动手操作的状态。<\/p>

希望新手通过本套视频全部掌握利用Altium Designer软件进行电子设计的基本流程，以及2层电路板的设计要点和方法，让我们从完全的小白正式跨入电子设计这个圈子。<\/p>

集成电路（简称IC）是现代电子产品的核心部件，其封装类型直接影响IC的性能、散热、安装方式及制造成本。封装不仅保护芯片内部的电路元件免受物理和化学损害，还方便电路的连接与安装。<\/p>

\"11.png\"<\/p>

一、集成电路封装的作用<\/strong><\/p>

封装的主要功能包括：<\/p>

保护芯片免受环境因素（如湿气、灰尘、机械冲击）的损害。<\/p>

实现电气连接，将芯片上的引脚扩展至外部。<\/p>

散热，防止芯片过热影响可靠性和性能。<\/p>

提供机械支撑和便于安装。<\/p>

二、常见的集成电路封装类型<\/strong><\/p>

按照封装的形态、引脚方式及安装方式，集成电路封装可分为多种类型，主要包括以下几类：<\/p>

1. 双列直插封装（DIP）<\/p>

特点：引脚排列在IC芯片的两侧直线排列，适合插入标准穿孔PCB。<\/p>

优点：结构简单，易于手工焊接和调试。<\/p>

缺点：体积较大，不适合高密度安装。<\/p>

应用：早期微控制器、逻辑芯片及射频电路。<\/p>

2. 小型封装及贴片封装（SMD\/SMT）<\/p>

这些封装适合表面贴装技术，能够满足现代电子产品对小型化和高密度的需求。<\/p>

(1) 小型封装（SOP\/SOP）<\/p>

封装体积小，侧面有引脚，适合自动贴装和波峰焊。<\/p>

常用型号有SOP、SSOP、TSSOP等。<\/p>

(2) 四方扁平封装（QFP）<\/p>

四边均带引脚，适合高引脚数芯片。<\/p>

封装平整，适合表面贴装。<\/p>

(3) 塑料引线框架封装（PLCC）<\/p>

引脚呈J形环绕封装体四周，适合插座或焊接。<\/p>

(4) 球栅阵列封装（BGA）<\/p>

引脚以球状焊盘分布在封装底部，信号线短且密度高。<\/p>

散热和性能优异，适合高速和高密度集成电路。<\/p>

制造过程要求较高，但广泛用于微处理器、存储器等关键芯片。<\/p>

(5) 芯片尺寸封装（CSP）<\/p>

封装尺寸接近芯片本体大小，体积极小。<\/p>

适合移动设备和空间受限的应用。<\/p>

3. 其他特殊封装类型<\/p>

TO封装：主要用于分立器件，如功率放大器和传感器。<\/p>

QFN：无引线扁平封装，采用裸露底部焊盘，具有良好散热性能和电气性能。<\/p>

LGA：使用底部焊盘，无引脚。<\/p>

SIP：单排引脚封装，结构简单，适用于某些特殊元件。<\/p>

三、封装材料<\/strong><\/p>

封装常用材料包括塑料、陶瓷和金属，塑料封装成本低，广泛采用于多数集成电路；陶瓷封装性能优良，常用于高频、高可靠领域。<\/p>

四、封装选型的考虑因素<\/strong><\/p>

应用需求：如速度、功耗、散热。<\/p>

安装工艺：穿孔或贴片。<\/p>

尺寸限制：产品空间大小。<\/p>

成本预算。<\/p>

环境条件：如温度、湿度。<\/p>

集成电路的封装类型丰富多样，各具特点。合理选择合适的封装类型，可以提高电子产品的性能和可靠性，同时降低制造难度和成本。<\/p>

在电子电路维护和故障排查中，万用表是一种基本且强大的工具，能够帮助工程师和技术人员快速定位电路中的短路和断路问题。其不仅能提高故障诊断效率，还能有效防止误操作导致的二次损坏。<\/p>

\"10.png\"<\/p>

一、准备工作<\/strong><\/p>

选择合适的万用表类型<\/p>

普通数字万用表（DMM）即可完成大多数短路和断路测试。需要确保电池电量充足，且测试线完好。<\/p>

断开电路电源<\/p>

为了安全和准确测量，务必先关闭电路电源，避免电压影响万用表读数，且防止设备损坏及人员安全问题。<\/p>

设定正确功能和量程<\/p>

将万用表调至“电阻挡”或“蜂鸣档”模式。蜂鸣档在测量短路时提供声音提示，更便于判断。<\/p>

二、确认短路<\/strong><\/p>

1. 短路的定义<\/p>

短路指电路中两个本不应该直接连通的点之间有低阻抗通路，可能因线路损坏、元件失效或焊接桥接等原因导致。<\/p>

2. 测量方法<\/p>

设定蜂鸣档：将万用表拨至蜂鸣档（导通测试档）。测试笔分别接触待测两点。<\/p>

判断音响和电阻值：当两点短路时，万用表将发出蜂鸣声或显示非常小的电阻值（通常接近0Ω）。<\/p>

重点检查电路关键节点，如电源正负极之间、信号线与地之间等。<\/p>

3. 注意事项<\/p>

测量短路时必须断电。<\/p>

如果读数显示高电阻或无穷大且无蜂鸣声，则说明没有短路。<\/p>

短路检测中，注意识别电容等元件带电阻的影响，避免误判。<\/p>

三、确认断路<\/strong><\/p>

1. 断路的定义<\/p>

断路指电路中某条线路或元器件内部导通路径中断，导致电流无法正常流通。<\/p>

2. 测量方法<\/p>

电阻挡测量：将万用表调至适当的电阻量程，将测试笔接触被测线路两端。<\/p>

观察读数：若显示为“OL”（无穷大）或极高阻值，说明断路。正常导通情况下应显示较低阻值。<\/p>

蜂鸣档辅助：在蜂鸣档下，断路两端无蜂鸣表示无导通。<\/p>

3. 检测步骤<\/p>

确认线路连续性，沿线路逐点测量。<\/p>

对疑似断路元件测量两端，如电阻、电感等应显示阻值，断路则显示无穷大。<\/p>

对断开的线路段进行相应修复。<\/p>

四、额外技巧和注意事项<\/strong><\/p>

在测量时保持测试笔稳定，避免误差。<\/p>

测量PCB线路时，参考电路图，辨识测试点。<\/p>

遇复杂电路时，结合电源电压和信号状态，综合判断故障。<\/p>

对电容、二极管等有极性元件，注意正确的测试方法和方向。<\/p>

总结来说，利用万用表进行短路和断路检测是电子维修中最基本也是最有效的方法。掌握正确的准备、设置和测量技巧，就能快速识别电路中的异常点，为后续维修提供准确依据。<\/p>

印刷电路板（PCB）的合理布局和布线是电子产品设计中的关键环节，直接影响电路的性能、可靠性和制造成本。良好的布局和布线不仅能减少电磁干扰（EMI），提高信号完整性，还能显著提升生产效率。<\/p>

\"4bba07c8ad67d56a0f418415b96370.png\"<\/p>

一、合理布局的原则<\/strong><\/p>

功能模块划分明确<\/p>

将整个电路按功能模块划分，如电源模块、信号处理模块、接口模块等。模块划分清晰后，尽量将相关元器件集中布置，方便互连，减少信号线长度，降低干扰。<\/p>

关键器件优先布局<\/p>

时钟电路、射频电路、高速信号线及模数转换器等关键部分尽量靠近，减少信号传输路径，提升系统性能。<\/p>

电源和接地布局合理<\/p>

电源和地线部分应保证低阻抗路径，通常采用宽铜箔或多层地、电平平面设计，减少电源噪声和地弹效应。<\/p>

注意散热需求<\/p>

高功率器件应布局在便于散热的位置，或者靠近散热孔和散热器，避免热量聚集造成元器件过热。<\/p>

留出合理空间<\/p>

保持元器件之间有适当间距，方便焊接和检修，同时避免元件过度密集导致布线困难和电气性能下降。<\/p>

二、布线的技巧与注意事项<\/strong><\/p>

信号线优先级排序<\/p>

高速、高频信号线优先布线，尤其是差分信号线要保持等长和恒定间距，确保信号同步和阻抗匹配。<\/p>

最小化信号线长度<\/p>

线长越短，信号衰减和干扰越小。尽量缩短信号路径，避免不必要的绕线。<\/p>

避免90度转弯<\/p>

信号线尽量采用45度斜线或圆弧，90度转弯容易引起信号反射和串扰。<\/p>

分层布线<\/p>

多层PCB可以将不同类型信号分层布线，如顶层为高速信号层，中间为地层和电源层，实现良好的屏蔽和 return path。<\/p>

电源和地线铺铜<\/p>

电源和地线部分要铺厚铜箔，形成稳固的电流通路，降低阻抗和噪声。<\/p>

注意信号与电源之间的隔离<\/p>

数字信号线和模拟信号线应分开布线，避免产生干扰。电源线和地线层尽量完整无断层。<\/p>

采用合理的走线宽度和间距<\/p>

根据电流大小和制造工艺选择合适的线宽，保证导电能力和耐久性。同时控制间距，防止短路和漏电。<\/p>

三、设计中的常用方法与工具<\/strong><\/p>

信号完整性分析<\/p>

利用信号完整性分析工具进行布线后的仿真，检测信号反射、串扰等问题，针对问题优化布线方案。<\/p>

设计规则检查（DRC）<\/p>

定期利用软件中的DRC功能检查布线是否满足工艺规则，如线宽、间距、焊盘尺寸等。<\/p>

PCB的合理布局和布线是一门综合艺术，需要设计者在性能、成本及工艺之间权衡取舍。遵循模块划分明确、信号路径最短、良好电源地设计及合理走线规则，配合现代设计工具的辅助，能显著提高电路板的性能和可靠性，实现优质的电子产品设计。<\/p>

PCB行业扩产潮来袭！400亿资本押注高端赛道<\/p>

<\/p>

\"b468e27331ce499e8ac00425041b9a.png\"<\/div>导语

2026年5月，PCB行业迎来史上最大规模扩产潮。胜宏科技、沪电股份、鹏鼎控股等头部企业公布的投资计划总额已超400亿元，扩产方向高度聚焦AI服务器、高频高速、封装基板等高端领域。这场由AI算力需求引爆的产能竞赛，正在重塑全球PCB产业竞争格局。<\/p>新闻详情

面对高端PCB供不应求的市场格局，国内头部PCB厂商率先吹响扩产号角。胜宏科技抛出行业最大规模扩产计划，2026年度投资总额不超过200亿元，其中约74%资金（约148亿元）将精准投向产能扩建与高端产线升级。<\/p>

鹏鼎控股计划在淮安园区投入80亿元扩充高阶PCB产能，预计2026年底产能翻倍；泰国一厂已试产，推进客户认证。公司2025年AI服务器类产品营收同比增长超1倍，预计2026年继续强劲增长。<\/p>

沪电股份以惊人的\"每月一投\"节奏推进高达176亿元的投资计划，成为业界瞩目的焦点。公司持续加码高端PCB产能，重点聚焦AI服务器、高速通信等领域。<\/p>

从业绩来看，这轮扩产潮已初见成效。深南电路一季度营收65.96亿元，创上市以来单季度新高，同比增长37.90%，归母净利润8.50亿元，同比增长73.01%。沪电股份一季度实现营收62.14亿元，同比增长53.91%，归母净利润12.42亿元，同比增长62.90%。<\/p>行业分析

多位业内人士表示，本轮扩产由AI算力需求爆发与上游材料供给刚性双重驱动，呈现显著的结构性特征。高端强涨、中端跟涨、低端弱稳，本质上是AI算力刚需与产能扩张滞后的共同作用。<\/p>

18层以上高多层板（HLC）增长率达到41.7%，成为AI PCB市场中占比约50%的核心组件。而这恰恰是技术壁垒森严的赛道——扩产周期长达2-3年，关键设备依赖进口，导致全球高端PCB产能持续紧缺。<\/p>

面对机遇，头部企业加速扩产的同时，也在加码技术升级。深南电路广州FC-BGA封装基板已实现22层及以下产品量产，无锡46亿扩产项目加码AI算力。广合科技已实现50层AI服务器PCB量产，拟投资26亿元建设云擎智造基地。<\/p>延伸展望

艾文智略首席投资官曹辙表示，未来PCB行业将从\"规模竞争\"向\"技术竞争\"转型。当前企业不再追求\"大而全\"的产能布局，而是聚焦高多层板、高频高速、IC载板、高阶HDI等高端技术赛道。<\/p>

高盛最新预测显示，2025-2030年AI服务器需求将增长约4.3倍，高端PCB供需失衡预计延续至2027年。只要算力需求不萎缩，高端PCB的缺口就很难弥合，龙头企业将享受行业β红利的同时，通过夺取更多市场份额获得显著的α收益。<\/p>

英伟达Rubin量产倒计时！A股PCB供应链迎来价值重估<\/p>

<\/p>

\"b12dba57be475eda70076aaf77b59f.png\"<\/div>导语

2026年5月21日，英伟达正式确认Vera Rubin平台将于下半年开始出货，标志着AI硬件供应链进入新一轮景气周期。作为下一代完整数据中心计算平台，Rubin单机PCB价值量达1.2万元（较Blackwell提升50%），层数达44-60层、线宽0.04mm，A股PCB产业链迎来历史性机遇。<\/p>新闻详情

英伟达CEO黄仁勋在GTC 2026大会上宣布，Vera Rubin平台已全面进入量产准备阶段，将于2026年下半年向微软、谷歌、亚马逊、Meta等头部云厂商首次发货，Q3开始ODM大规模出货，Q4全面放量。<\/p>

Rubin架构的核心配置是NVL72系统，搭载72颗Rubin GPU和36颗Vera CPU，可提供3.6 exaflops的NVFP4推理算力和2.5 exaflops的训练算力。在机柜层面，Rubin较Blackwell实现5倍推理性能提升，同时将单Token成本降低10倍。<\/p>

从供应链价值来看，Rubin单机柜售价1.8万美元，其中高端PCB价值量达1.2万元（Blackwell约8000元），提升幅度达50%。这一提升主要来自三个方面：一是PCB面积更大，承载更多芯片；二是层数从40层提升至44-60层；三是采用M9级高频高速材料，工艺复杂度显著增加。<\/p>

全球仅5家厂商具备Rubin PCB生产能力，A股核心受益标的包括：胜宏科技（300476）作为英伟达GPU PCB全球第一供应商，独家供应GB300五阶HDI板，H200算力板份额约70%；沪电股份（002463）为GB300提供40层高多层板，北美AI服务器主板市占率超80%；深南电路（002916）高端PCB+IC载板双布局，供货Rubin高速背板。<\/p>行业分析

Rubin平台的量产将带动高端PCB进入新一轮涨价周期。机构测算，2026年全球AI服务器PCB市场规模将达214亿美元，同比增长113%；2027年继续保持70%以上增速。<\/p>

上游材料端，生益科技（600183）作为大陆唯一通过英伟达M9认证的覆铜板厂商，将充分受益于Rubin平台带来的高端材料需求爆发。M9级材料需求2026年预计同比增长200%以上，订单已排至2027年。<\/p>

值得关注的是，Rubin量产时间表提前对供应链提出更高要求。原计划2027年Q1量产现提前至2026年下半年，留给供应链的准备时间被压缩，认证进度领先的企业将获得先发优势。<\/p>延伸展望

展望未来，随着Rubin平台逐步放量，A股PCB产业链将进入业绩兑现期。机构建议重点关注三类机会：一是深度绑定英伟达的高端PCB供应商；二是M9级覆铜板材料龙头；三是具备垂直整合能力的产业链一体化企业。<\/p>

风险提示方面，需关注海外出口管制政策变动、行业竞争加剧导致的价格波动，以及上游原材料成本上行等潜在风险。<\/p>

电子布涨价80%！AI高端需求爆发逼退普通产能<\/p>

<\/p>

\"d936b8fc4764945e8d9ffbd56f2ba5.png\"<\/div>导语

2026年5月，电子级玻璃纤维布市场正经历剧烈分化：AI高端电子布因需求爆发量价齐升，价格连涨四轮；而大量织布机被转产至高端领域，导致普通电子布备货库存降至历史低位。这场由AI算力驱动的材料革命，正在重塑整个玻纤布产业链的竞争格局。<\/p>新闻详情

电子布是覆铜板（CCL）的核心增强基材，与树脂结合后支撑PCB的结构强度和信号传输性能。看似普通的玻璃纤维布，却是AI服务器、5G基站、高端手机的核心\"骨架材料\"。<\/p>

据行业数据显示，2025年10月以来，电子布行业进入\"量价齐升\"的超级景气周期：普通厚布价格大幅上涨，累计涨幅超80%；高端超薄布、低介电布、石英布价格更是暴涨。宏和科技、菲利华、中材科技等主打高端产品的企业，净利润迎来爆发式增长。<\/p>

这场涨价潮的本质，是AI服务器对高端电子布的刚需爆发。一台AI服务器所用高端电子布是普通服务器的十倍以上，只能选用高端特制布料。全球AI产业飞速扩张，直接带动高端电路板需求飙升，上游高端电子布瞬间供不应求。<\/p>

在A股市场，电子布细分赛道已跑出多只牛股。宏和科技主打超薄极薄电子布，是AI赛道弹性最强的标的；菲利华独家量产石英电子布（Q布），技术壁垒无人可比；中材科技布局全系列低介电布料，客户资源扎实过硬。三家企业全部通过头部产业链认证，订单常年饱满。<\/p>行业分析

电子布行业的核心壁垒在于配方、工艺和认证。配方专利被海外厂商垄断，超细纱拉丝、超薄布织造等工艺要求极高，进入头部客户供应链的认证周期长达1-2年。<\/p>

值得关注的是，供给端正在发生结构性变化。高端电子布需求旺盛，吸引大量织布机转产至高端领域，导致普通电子布产能被挤占，备货库存均降至历史低位。这种\"高端强涨、低端被动跟涨\"的格局，本质上是AI算力刚需与产能扩张滞后的共同作用。<\/p>

中国巨石作为全球玻纤行业绝对龙头，玻纤纱、电子布产能全球第一、Low DK布产能国内第二。国际复材薄布\/超薄布库存为零，2026年一季度净利暴涨412.94%，深度绑定深南电路、生益科技等PCB大厂。<\/p>延伸展望

展望未来，随着AI大模型迭代和Agent应用爆发，AI服务器需求将持续增长，高端电子布的供需缺口短期内难以填补。业内人士判断，这一轮高景气至少能维持2-3年。<\/p>

投资机会方面，高端电子布赛道是行业利润最高、前景最好的核心赛道，包含超薄布、极薄布、石英布、低介电布三大品类。普通电子布赛道则受益于行业涨价周期，业绩稳步增长。<\/p>

长期来看，电子布行业将从\"规模竞争\"向\"技术竞争\"转型。当前企业不再追求\"大而全\"的产能布局，而是聚焦高多层板、高频高速、IC载板等高端技术赛道，集中资源攻克核心技术难题。<\/p>
