PCB 布線原則連線精簡(jiǎn)原則連線要精簡(jiǎn)，盡可能短，盡量少拐彎，力求線條簡(jiǎn)單明了，特別是在高頻回路中，當(dāng)然為了達(dá)到阻抗匹配而需要進(jìn)行特殊延長(zhǎng)的線就例外了，例如蛇行走線等。安全載流原則銅線的寬度應(yīng)以自己所能承載的電流為基礎(chǔ)進(jìn)行設(shè)計(jì)，銅線的載流能力取決于以下因素：線寬、線厚（銅鉑厚度）、允許溫升等，下表給出了銅導(dǎo)線的寬度和導(dǎo)線面積以及導(dǎo)電電流的關(guān)系（軍品標(biāo)準(zhǔn)），可以根據(jù)這個(gè)基本的關(guān)系對(duì)導(dǎo)線寬度進(jìn)行適當(dāng)?shù)目紤]。印制導(dǎo)線最大允許工作電流（導(dǎo)線厚50um，允許溫升10℃）導(dǎo)線寬度（Mil） 導(dǎo)線電流（A） 其中:K 為修正系數(shù)，一般覆銅線在內(nèi)層時(shí)取0.024，在外層時(shí)取0.048；T 為最大溫升，單位為℃;A 為覆銅線的截面積，單位為mil（不是mm，注意）；I 為允許的最大電流，單位是A。電磁抗干擾原則電磁抗干擾原則涉及的知識(shí)點(diǎn)比較多，例如銅膜線的拐彎處應(yīng)為圓角或斜角（因?yàn)楦哳l時(shí)直角或者尖角的拐彎會(huì)影響電氣性能）雙面板兩面的導(dǎo)線應(yīng)互相垂直、斜交或者彎曲走線，盡量避免平行走線，減小寄生耦合等。一、 通常一個(gè)電子系統(tǒng)中有各種不同的地線，如數(shù)字地、邏輯地、系統(tǒng)地、機(jī)殼地等，地線的設(shè)計(jì)原則如下：1、 正確的單點(diǎn)和多點(diǎn)接地在低頻電路中，信號(hào)的工作頻率小于1MHZ，它的布線和器件間的電感影響較小，而接地電路形成的環(huán)流對(duì)干擾影響較大，因而應(yīng)采用一點(diǎn)接地。當(dāng)信號(hào)工作頻率大于10MHZ 時(shí)，如果采用一點(diǎn)接地，其地線的長(zhǎng)度不應(yīng)超過(guò)波長(zhǎng)的1/20，否則應(yīng)采用多點(diǎn)接地法。2、 數(shù)字地與模擬地分開(kāi)若線路板上既有邏輯電路又有線性電路，應(yīng)盡量使它們分開(kāi)。一般數(shù)字電路的抗干擾能力比較強(qiáng)，例如TTL 電路的噪聲容限為0.4~0.6V，CMOS 電路的噪聲容限為電源電壓的0.3~0.45 倍，而模擬電路只要有很小的噪聲就足以使其工作不正常，所以這兩類(lèi)電路應(yīng)該分開(kāi)布局布線。3、 接地線應(yīng)盡量加粗若接地線用很細(xì)的線條，則接地電位會(huì)隨電流的變化而變化，使抗噪性能降低。因此應(yīng)將地線加粗，使它能通過(guò)三倍于印制板上的允許電流。如有可能，接地線應(yīng)在2~3mm 以上。4、 接地線構(gòu)成閉環(huán)路只由數(shù)字電路組成的印制板，其接地電路布成環(huán)路大多能提高抗噪聲能力。因?yàn)榄h(huán)形地線可以減小接地電阻，從而減小接地電位差。二、 配置退藕電容PCB 設(shè)計(jì)的常規(guī)做法之一是在印刷板的各個(gè)關(guān)鍵部位配置適當(dāng)?shù)耐伺弘娙荩伺弘娙莸囊话闩渲迷瓌t是：?電電源的輸入端跨½10~100uf的的電解電容器，如果印制電路板的位置允許，采Ó100uf以以上的電解電容器抗干擾效果會(huì)更好¡���?原原則上每個(gè)集成電路芯片都應(yīng)布置一¸0.01uf~`0.1uf的的瓷片電容，如遇印制板空隙不夠，可Ã4~8個(gè)個(gè)芯片布置一¸1~10uf的的鉭電容（最好不用電解電容，電解電容是兩層薄膜卷起來(lái)的，這種卷起來(lái)的結(jié)構(gòu)在高頻時(shí)表現(xiàn)為電感，最好使用鉭電容或聚碳酸醞電容）。���?對(duì)對(duì)于抗噪能力弱、關(guān)斷時(shí)電源變化大的器件，ÈRA、¡ROM存存儲(chǔ)器件，應(yīng)在芯片的電源線和地線之間直接接入退藕電容¡���?電電容引線不能太長(zhǎng)，尤其是高頻旁路電容不能有引線¡三¡過(guò)過(guò)孔設(shè)¼在高ËPCB設(shè)設(shè)計(jì)中，看似簡(jiǎn)單的過(guò)孔也往往會(huì)給電路的設(shè)計(jì)帶來(lái)很大的負(fù)面效應(yīng)，為了減小過(guò)孔的寄生效應(yīng)帶來(lái)的不利影響，在設(shè)計(jì)中可以盡量做到£���?從從成本和信號(hào)質(zhì)量?jī)煞矫鎭?lái)考慮，選擇合理尺寸的過(guò)孔大小。例如¶6- 10層層的內(nèi)存模¿PCB設(shè)設(shè)計(jì)來(lái)說(shuō)，選Ó10/20mi（（鉆¿焊焊盤(pán)）的過(guò)孔較好，對(duì)于一些高密度的小尺寸的板子，也可以嘗試使Ó8/18Mil的的過(guò)孔。在目前技術(shù)條件下，很難使用更小尺寸的過(guò)孔了（當(dāng)孔的深度超過(guò)鉆孔直徑µ6倍倍時(shí)，就無(wú)法保證孔壁能均勻鍍銅）；對(duì)于電源或地線的過(guò)孔則可以考慮使用較大尺寸，以減小阻抗¡���?使使用較薄µPCB板板有利于減小過(guò)孔的兩種寄生參數(shù)¡���? PCB板板上的信號(hào)走線盡量不換層，即盡量不要使用不必要的過(guò)孔¡���?電電源和地的管腳要就近打過(guò)孔，過(guò)孔和管腳之間的引線越短越好¡���?在在信號(hào)換層的過(guò)孔附近放置一些接地的過(guò)孔，以便為信號(hào)提供最近的回路。甚至可以ÔPCB板板上大量放置一些多余的接地過(guò)孔¡四¡降降低噪聲與電磁干擾的一些經(jīng)Ñ?能能用低速芯片就不用高速的，高速芯片用在關(guān)鍵地方¡?可可用串一個(gè)電阻的方法，降低控制電路上下沿跳變速率¡?盡盡量為繼電器等提供某種形式的阻尼，ÈRC設(shè)設(shè)置電流阻尼¡?使使用滿(mǎn)足系統(tǒng)要求的最低頻率時(shí)鐘¡?時(shí)時(shí)鐘應(yīng)盡量靠近到用該時(shí)鐘的器件，石英晶體振蕩器的外殼要接地¡?用用地線將時(shí)鐘區(qū)圈起來(lái)，時(shí)鐘線盡量短¡?石石英晶體下面以及對(duì)噪聲敏感的器件下面不要走線¡?時(shí)時(shí)鐘、總線、片選信號(hào)要遠(yuǎn)ÀI/O線線和接插件¡?時(shí)時(shí)鐘線垂直ÓI/O線線比平行ÓI/O線線干擾小¡?

The effect of many factors which affect the harmonic wave testing is analysed. The way of improving the performance of ferrite cores is put forward. Key words: ratio loss coefficient，hysteresis constant，DC-Bias，THD 近年來(lái)，變壓器生產(chǎn)廠家和軟磁鐵氧體生產(chǎn)廠家，在電感器和變壓器產(chǎn)品的總諧波失真指標(biāo)控制上，進(jìn)行了深入的探討和廣泛的合作，逐步弄清了一些似是而非的問(wèn)題。從工藝技術(shù)上采取了不少有效措施，促進(jìn)了質(zhì)量問(wèn)題的迅速解決。本文將就此熱門(mén)話(huà)題作一些粗淺探討。 一、 歷史回顧 總諧波失真（Total harmonic distortion） ，簡(jiǎn)稱(chēng)THD，并不是什么新的概念，早在幾十年前的載波通信技術(shù)中就已有嚴(yán)格要求<1>。1978年郵電部公布的標(biāo)準(zhǔn)YD/Z17－78“載波用鐵氧體罐形磁心”中，規(guī)定了高μQ材料制作的無(wú)中心柱配對(duì)罐形磁心詳細(xì)的測(cè)試電路和方法。如圖一電路所示，利用LC組成的150KHz低通濾波器在高電平輸入的情況下測(cè)量磁心產(chǎn)生的非線性失真。這種相對(duì)比較的實(shí)用方法，專(zhuān)用于無(wú)中心柱配對(duì)罐形磁心的諧波衰耗測(cè)試。 這種磁心主要用于載波電報(bào)、電話(huà)設(shè)備的遙測(cè)振蕩器和線路放大器系統(tǒng)，其非線性失真有很?chē)?yán)格的要求。 圖中 ZD —— QF867 型阻容式載頻振蕩器，輸出阻抗 150Ω， Ld47 —— 47KHz 低通濾波器，阻抗 150Ω，阻帶衰耗大于61dB， Lg88 ——并聯(lián)高低通濾波器，阻抗 150Ω，三次諧波衰耗大于61dB Ld88 ——并聯(lián)高低通濾波器，阻抗 150Ω，三次諧波衰耗大于61dB FD —— 30～50KHz 放大器， 阻抗 150Ω， 增益不小于 43 dB，三次諧波衰耗b3(0)≥91 dB, DP —— Qp373 選頻電平表，輸入高阻抗， L ——被測(cè)無(wú)心罐形磁心及線圈， C ——聚苯乙烯薄膜電容器CMO-100V-707APF±0.5%,二只。 測(cè)量時(shí)，所配用線圈應(yīng)用絲包銅電磁線SQJ9×0.12(JB661-75)在直徑為16.1mm的線架上繞制 120 匝， （線架為一格） ， 其空心電感值為 318μH（誤差1％） 被測(cè)磁心配對(duì)安裝好后，先調(diào)節(jié)振蕩器頻率為 36.6～40KHz， 使輸出電平值為+17.4 dB， 即選頻表在 22′端子測(cè)得的主波電平 （P2）為+17.4 dB，然后在33′端子處測(cè)得輸出的三次諧波電平（P3）， 則三次諧波衰耗值為：b3(+2)= P2+S+ P3 式中：S 為放大器增益dB 從以往的資料引證， 就可以發(fā)現(xiàn)諧波失真的測(cè)量是一項(xiàng)很精細(xì)的工作，其中測(cè)量系統(tǒng)的高、低通濾波器，信號(hào)源和放大器本身的三次諧波衰耗控制很?chē)?yán)，阻抗必須匹配，薄膜電容器的非線性也有相應(yīng)要求。濾波器的電感全由不帶任何磁介質(zhì)的大空心線圈繞成，以保證本身的“潔凈” ，不至于造成對(duì)磁心分選的誤判。 為了滿(mǎn)足多路通信整機(jī)的小型化和穩(wěn)定性要求， 必須生產(chǎn)低損耗高穩(wěn)定磁心。上世紀(jì) 70 年代初，1409 所和四機(jī)部、郵電部各廠，從工藝上改變了推板空氣窯燒結(jié)，出窯后經(jīng)真空罐冷卻的落后方式，改用真空爐，并控制燒結(jié)、冷卻氣氛。技術(shù)上采用共沉淀法攻關(guān)試制出了μQ乘積 60 萬(wàn)和 100 萬(wàn)的低損耗高穩(wěn)定材料，在此基礎(chǔ)上，還實(shí)現(xiàn)了高μ7000～10000材料的突破，從而大大縮短了與國(guó)外企業(yè)的技術(shù)差異。當(dāng)時(shí)正處于通信技術(shù)由FDM（頻率劃分調(diào)制）向PCM（脈沖編碼調(diào)制） 轉(zhuǎn)換時(shí)期， 日本人明石雅夫發(fā)表了μQ乘積125 萬(wàn)為 0.8×10 ，100KHz）的超優(yōu)鐵氧體材料<3>，其磁滯系數(shù)降為優(yōu)鐵
