你可能喜欢如下图，在PCB板中做钻孔以下2种效果有什么不同？这些孔我是用来作为PCB板的4个角螺丝固定位用的。对于图中金色的那个过孔是VIA来的，有些制版厂说如果做这种效果就定义为金属钻孔，请问何为金属钻与普通钻孔有何区别？

分为有铜孔和无铜孔的区别。
是带有铜皮的过孔和没带有铜皮过孔的区别吗
嗯，理解正确，一般的螺丝孔多数是做无铜孔多，这个做无铜有铜你是可以跟pcb板厂家要求的。
那做有铜的有什么好处
我是做电视机板和电源板的，我之前有跟一些电路板设计师聊过，他们说如果是螺丝孔有铜的话上螺丝后会影响电路板的信号，或者是引起静电会对贴片零件有损坏，造成信号干扰电视看不清楚等问题，所以电视机板和电源板的螺丝孔都不会做有铜的。
那还得看线路板的类型使用场合
嗯，还要看你的线路板的类型是什么的，是做什么的，不过我建议你螺丝孔不要做有铜的。很容易电流大引起线路板短路的，这个在LED灯板上是最突出，LED的板材相对比较差，如果是在装配密封性不好的话，下雨潮湿短路都会没用报废的，所以我们有时候看红色的LED显示屏的字都是断断续续的。

Over the years the special chemical fiber development has always been a hot growth, but in profiled fiber cross-section shape variety development, using the basic mechanism of fabric, wicking function evaluation methods etc. the system research is not mature enough. There are a wide open on the whole is not high, according to the actual use of the mechanism of depth is not enough, not the actual performance evaluation standard. Is in this paper based on profiled fiber and moisture wicking fabric development and characterization of practical difficulties, around the following content made a profound research and discussion: system analysis of the textile fabric moisture absorption mechanism, understand the wetting and wicking and contact angle mainly basic concepts and principles. The water contact fabric method differences, divided into ordinary fabric moisture wicking and unlimited water water wicking scene infinite quantity. The textile fabric core ceiling of different scene produce reason and evaluation method to carry on the deep discussion. It is pointed out that the wetting and wicking is hygroscopic textiles scene in two stages, namely the wicking is in the wetting basically produced in the fiber between the eve of the hygroscopic range scene. Fiber aggregate capillary space imitation and liquid speculation. To discuss the effect of hydrophobic profiled polyester fiber bundle of capillary effect of many factors, such as fiber between capillary pore size and spreading, the external shape of the cross section of the fiber, fiber than area and outside characteristics of fiber, fiber moisture absorption function, liquid characteristics. By computer imitation skills to establish a fiber bundle unit model MFB and fiber beam stochastically disaggregated imitate system shape a generator, to research fiber beam single fiber cross-section shape, fiber bundle in the capillary free size and spreading, fiber radius is small, fiber and capillary Guan Genshu etc. the core ceiling effect. On the basis of analysis of the results of imitation stop guessing shaped fiber bundle wicking effect, from found a series of discipline of single fiber cross-section shape change influence on fiber aggregate capillary effect. The external shape of the cross section of the single fiber of fiber bundle external capillary leisure composition and spread influence is very big, shaped like a cross such concave cross section shape is more beneficial in capillary and capillary equivalent radius of many in (1 ~ 2 * 10 6m) low value area spread. Strange fineness of yarn, single fiber radius is small, in the fiber bundle includes the fiber root number, a capillary leisure more and in the low value
although cross fiber bundle including fiber root number peaked at 140 ~ 150, but single fiber structure of capillary pores to is not as good as king of shaped fibers. Will be more than two kinds of many kinds of section shape of fiber blended in a way, in the fiber bundle of capillary leisure constitute situation will not have improved significantly due to the section shape of the varieties growth, but the variety of concave cross section shape of blended fiber bundle of capillary leisure constitution situation is significantly beneficial in shaped like a triangle convex cross-section shape blending and the fiber bundle. Through the process of establish the imitation speculation system, can preliminary design differences of single fiber cross-section shape, again through the process of guessing fiber aggregates capillary effect and to optimize the shape of section, thus greatly decreased fiber type development in the process of capital spending. This is to imitate the system, speculation has the very big significance and good economic benefits of special chemical fiber research and development. Systematic research textile hygroscopic moisture concept and reason. In the theoretical study of textile fiber aggregates wicks ceiling effect mechanism of important discuss the following: through figuring process critical dispersion coefficient to compare the level of difficulty of the round and special-shaped fiber wetting action. It is confirmed that the fibrous material under the condition of profiled fiber more easily wet, such as cross the critical dispersion coefficient 0. 8700 round - 0 less than gamma. 8571 gamma. On the basis of the actual model of Reed & Wilson, application of vertical wicking model of fiber bundle in infinite water quantity of core ceiling picture stop mechanics analysis derived absorption core of profiled fiber beam height, wicking time and wicking speed practical formula to calculate, and combined with computer simulating result, on core fiber beam ceiling effect to stop speculation, the invention of cross and double cross shaped static wicking effect is more significant. Discuss the useful circles within the fiber bundle of capillary free size values results, explaining the fiber bundle has a fundamental premise of external leisure for the capillary effect of pore radius is greater than 0. 01 liquid cone column main shape function characterization of profiled fiber bundle vertical wicking function is proposed to analyze the shape function of angle has the positive significance to the evaluation of the beam shaped fiber wicking static contact. The results showed the number of fibers cross shaped fiber bundle up, with 0 (x) minimum distribution. Effect of the thickness of the fiber of diameter 0 (x) are more significant, when the other parameters are fixed, coarse fiber of the fiber bundle, Phi 0 (x) smaller. Suction function testing instrument and measures in the textile materials core further innovation and improvement. So far, profiled fiber is important to use in the efficacy of moisture wicking fabric development, but this kind of fabric core ceiling function characterization of actually not fair and perfect. In view of the sample material, structure and eventually product use differences should be reasonable selects the appropriate tests to characterize the wicking performance characteristics, the subject innovation take the OCA40 micro optical contact angle measuring instrument open up unlimited water droplet 3S application type micro balance capillary water tester test samples verti research and development of the demand Absorbency - liquid core ceiling tester fabric degree core ceiling function. The three differences Wicking Test method can more comprehensive characterization of samples in different water suction and core wicking method under the wicking function, constitute a match the textile materials moisture absorption and conduction function test system completely. Take OCA40 micro optical contact angle measuring instrument of unlimited water under the premise of droplet wicking micro Ya picture stop indecent observes the research. The first to put forward the droplet wicking process based on the wicking height and wicking time can be divided into wicking time and wicking time for the main. Through analysis droplet core compared to the wicking whole process of suction time and the main core ceiling the length of time and the time of the spread, cruciform and flat fiber aggregates invention has faster subject wicking time. The main core of flat fabric suction time is the shortest, the most Nianye wicking speed, but the preparation time is relatively longer wicking. Overall, figure ten wicking fabric is the most excellent result. The droplet wicking body the time stop linear fitting analysis, the invention of this six kinds of special-shaped fabric core absorption kinetics showed a good linear consequences. The results of the annotation of COOLDRY / cotton blended fabrics and U / cotton double absorbent fabric, blended surface droplets in the assessment in wicking kinetics still insist on a good linear relationship. In three kinds of nonwoven effect type absorbent fabric as example, using 3S Balance capillary water tester, take the static relationship between vertical wicking test method to study the fabric wicking liquid component and time. Through measuring fabric core ceiling when constitute the core components of liquid column, brooding wicking fabric outside static contact angle are 50 to 60 wicking kinetics, discuss the outer fabric wick ceiling static contact angle algorithm, the invention of textile materials to external static state contact angle in the liquid static transmission basically is 0 degrees, in textile material outside the liquid activity is cause wicking scene of important factors. Through the analysis of the process of fabric core ceiling liquid wicking kinetics, based on Washburn liquid capillary movement principle, wicking components and core ceiling fitting of the square root of time both invention has a good linear relationship. The linear fitting degree have reached more than 95%. Take the capillary leisure equivalent radius characterization of static wicking fabrics external capillary leisure size, calculation results and the second chapter, we establish the computer imitation results fundamental differences, which belongs to the uniform number class 10 6m degree. Analysis of the outer fabric wicking of liquid volume and fabric liquid bearing coefficient, to compare the fabric and liquid influence on wicking effect that not all liquid in textile materials produced wicking scene can fill all the pores. Like the liquid water in the V7 when the wicking rate is 90% with you. Fiber material of hydrophilic functional contraction of wicking, leisure capillary size, static con fabric processing and dyeing and finishing process is added to the hydrophilic or hydrophobic chemical reagents of core ceiling consequences also has certain effect needs according to the product use selected te to in the liquid quantitative inorganic outside active agents, in wicking effect. Developed the Demand Absorbency liquid level wicking test instrument, using the instrument of three kinds of nonwoven fabric moisture wicking function to stop the degree of Wicking Test and analysis. Through the process of experimental data analysis and comparison of exploratory testing, slowly put forward the test pace of revising the plan, after the correction results confirm the data obtained from the tests with superior discipline. The degree of wicking fabric testing results of notes, in a certain pressure under the premise of wicking fabric reaches the saturation in the process of absorption component and time square root has a linear relationship with the superior, and the fitting degree was more than 99%. As a liquid core data as absorption degree of textile is consistent with Washburn capillary wicking principle and vertical wicking. The wicking reaches the saturation, liquid and no capillary occupied all external leisure fabric, liquid filled in the rate of 70 to 80%. Wicking fabric saturation and wicking speed does not have linear coherence. The wicking rate of fabric by wicking effect is in direct contact with the water supply method, fabric and liquid wicking area. The vertical core fabric suction and degree of wicking in reason are consistent with Washburn capillary wicking principle, water absorbing method but the core difference has some differences from their separation characteristics. Divergence of two ways to test the water supply method, making fabric contact with water area of big differences, which leads to the fabric of the integrated core ceiling effects show different dynamic characteristics, the ordinary, the degree of wicking speed is 4 ~ 5 times your vertical wicking. Methods taken in the research of vertical suction core fabric micro wicking accurate static mechanical ordinary, and large amount of water in the characterization of the fabric is more suitable to the degree of functional wicking method. As long as the use of according to the product differences and the large amount of water, small differences to affirm the testing method and the characterization method is reasonable and useful. The subject of profiled fiber to imitate the actual chemical fiber type development provides a we understand the liquid the profiled fiber aggregation characteristics o set according to the actual absorbent fabrics Standard Test and characterization studies.目录:中文摘要11-15英文摘要15-17第1章 绪论18-38&&&&1.1 研究背景与意义18-22&&&&&&&&1.1.1 吸湿排汗类面料发展近况18-19&&&&&&&&1.1.2 异形纤维的开发和应用19-21&&&&&&&&1.1.3 吸湿排汗类纺织品研究存在问题21-22&&&&1.2 研究内容相关概念体系22-31&&&&&&&&1.2.1 纺织材料润湿和芯吸机理22-28&&&&&&&&1.2.2 纺织多孔介质中液体的流动机理研究28-29&&&&&&&&1.2.3 纤维集合体吸湿模拟理论29-30&&&&&&&&1.2.4 纺织品吸湿性能评价体系30-31&&&&1.3 本课题研究内容、方法与创新点31-32&&&&1.4 本章小结32&&&&参考文献32-38第2章 异形纤维集合体芯吸流动模拟理论38-67&&&&2.1 异形纤维束模拟的背景意义39-40&&&&2.2 已有纤维集合体堆砌排列模型40-41&&&&&&&&2.2.1 Schwarz理想化模型40&&&&&&&&2.2.2 D.Lukas和潘宁的纤维束浸润模型40-41&&&&&&&&2.2.3 织物组织结构模型41&&&&2.3 Shape Generator-异形纤维束随机模拟系统41-50&&&&&&&&2.3.1 纤维束随机模拟系统的假设42-47&&&&&&&&&&&&(1) 纤维束单元模型假设的物理意义42-44&&&&&&&&&&&&(2) 纤维束截面无规随机排列模拟的意义44-46&&&&&&&&&&&&(3) 纤维束随机模拟系统的假设条件46-47&&&&&&&&2.3.2 纤维束随机模拟系统的原理47-50&&&&&&&&&&&&(1) 模拟系统的物理基础47-48&&&&&&&&&&&&(2) SG纤维束截面随机模拟软件运行原理48-49&&&&&&&&&&&&(3) 单纤维截面设计49-50&&&&2.4 纤维束随机模拟结果与分析50-63&&&&&&&&2.4.1 异形纤维束模拟图50-52&&&&&&&&2.4.2 截面形状对异形纤维束内毛细空隙分布的影响52-55&&&&&&&&2.4.3 纤维半径对异形纤维束毛细空隙分布的影响55-58&&&&&&&&2.4.4 不同截面形状混纺对异形纤维束毛细空隙分布的影响58-60&&&&&&&&2.4.5 异形纤维束毛细流动效应预测分析60-63&&&&2.5 本章小结63-64&&&&参考文献64-67第3章 液体在异形纤维集合体内的流动研究67-89&&&&3.1 纺织品芯吸流动理论67-69&&&&3.2 异形纤维束芯吸浸润的临界扩散69-72&&&&3.3 纤维束垂直芯吸物理模型72-73&&&&3.4 纤维束芯吸流量、时间及速率计算73-76&&&&&&&&3.4.1 纤维束芯吸流量73-74&&&&&&&&3.4.2 纤维束液体芯吸时间计算74-75&&&&&&&&3.4.3 纤维束初始瞬间芯吸速率75-76&&&&3.5 异形纤维束芯吸性能预测研究76-80&&&&&&&&3.5.1 异形纤维束模型在预测中的应用76-77&&&&&&&&3.5.2 纤维束静态及动态芯吸预测分析77-80&&&&&&&&&&&&(1) 静态芯吸饱和最大高度78&&&&&&&&&&&&(2) 芯吸时间78&&&&&&&&&&&&(3) 芯吸动态过程研究78-80&&&&&&&&&&&&(4) 芯吸初始瞬间速度80&&&&3.6 毛细空隙当量半径的界值分析80-82&&&&3.7 垂直纤维束芯吸的液柱形态变化及动态接触角研究82-86&&&&3.8 本章小结86-87&&&&参考文献87-89第4章 纺织材料芯吸性能测试方法与原理89-110&&&&4.1 纺织材料芯吸性能测试方法与原理89-96&&&&&&&&4.1.1 静态法垂直芯吸测试90-91&&&&&&&&4.1.2 动态法织物芯吸测试91-92&&&&&&&&4.1.4 纺织品芯吸性能的表征方法92-93&&&&&&&&4.1.5 纺织品芯吸性能评价优化选择方法93-96&&&&4.2 有限水源液滴芯吸测试仪器与测试方法96-99&&&&&&&&4.2.1 OCA40 Micro光学视频接触角测量仪器原理96-98&&&&&&&&4.2.2 有限水源液滴芯吸测试方法98-99&&&&4.3 3S Balance毛细水测试仪器和测试方法99-103&&&&&&&&4.3.1 3S Balance毛细水测试仪器原理100-102&&&&&&&&4.3.2 3S Balance毛细水测试仪实验方法102-103&&&&4.4 Demand Absorbency—液体水平芯吸测试仪器与测试方法103-107&&&&&&&&4.4.1 Demand Absorbency—液体水平芯吸测试仪器原理103-106&&&&&&&&4.4.2 Demand Absorbency—液体水平芯吸测试方法106-107&&&&4.5 本章小结107&&&&参考文献107-110第5章 异形纤维集合体有限水源芯吸性能110-122&&&&5.1 OCA40 Micro光学视频接触角测量仪实验方案111-112&&&&&&&&5.1.1 异形聚酯面料试样111-112&&&&&&&&5.1.2 异形聚酯纤维/棉混纺面料试样112&&&&5.2 异形聚酯纤维集合体水液滴芯吸性能测试结果112-118&&&&&&&&5.2.1 液滴在单根异形纤维上的芯吸现象112-113&&&&&&&&5.2.2 液滴在异形聚酯纤维集合体上的吸附现象113-115&&&&&&&&5.2.3 异形聚酯纤维集合体液滴吸附动力学研究115-118&&&&5.3 异形聚酯纤维/棉混纺吸湿排汗面料水液滴芯吸性能测试结果118-120&&&&&&&&5.3.1 异形纤维(COOLDRY)与棉混纺面料芯吸性118&&&&&&&&5.3.2 U形/棉双层差动吸湿面料的芯吸性能118-120&&&&5.4 本章小结120-121&&&&参考文献121-122第6章 功能型吸湿面料垂直芯吸性能122-143&&&&6.1 非织造布高吸湿面料垂直芯吸实验方案设计122-124&&&&6.2 非织造布高吸湿面料试样特征重量测试结果124&&&&6.3 非织造布高吸湿面料与液体动态芯吸接触角124-128&&&&&&&&6.3.1 正癸烷(Decane)溶液动态芯吸接触角126&&&&&&&&6.3.2 液态水动态芯吸接触角126-127&&&&&&&&6.3.3 异丙醇(Isopropanol)溶液动态芯吸接触角127-128&&&&6.4 非织造布高吸湿面料中芯吸的液体体积128-129&&&&6.5 非织造布高吸湿面料的液体承载重量129-130&&&&6.6 非织造布高吸湿面料的垂直芯吸动力学130-135&&&&6.7 非织造布吸湿面料内部毛细动态接触角135-137&&&&6.8 非织造布高吸湿面料内部毛细空隙当量半径137-141&&&&6.9 本章小结141-142&&&&参考文献142-143第7章 功能型吸湿面料水平芯吸性能143-162&&&&7.1 Demand Absorbency—液体水平芯吸测试探索方案143&&&&7.2 功能型吸湿面料水平芯吸性能测试结果分析143-147&&&&7.3 Demand Absorbency—液体水平芯吸测试修正方案147-149&&&&7.4 功能型吸湿面料水平芯吸性能测试结果149-159&&&&&&&&7.4.1 面料水平芯吸动态分析149-156&&&&&&&&7.4.2 面料水平芯吸状态分析156-159&&&&7.5 织物垂直芯吸动力学与水平芯吸动力学拟合对比分析159-160&&&&7.6 本章小结160-161&&&&参考文献161-162第8章 结论与课题展望162-167附录1 芯吸高度和时间关系公式推导过程167-169附录2 3S Balance实验数据例2169-172附录3 水平需求芯吸测试相关实验数据172-174博士期间发表文章174-175致谢175分享到：相关文献|
