Jordbaner og jordplaner har impedans. N\u00e5r der l\u00f8ber str\u00f8m gennem en jordbane, vil der opst\u00e5 en sp\u00e6nding p\u00e5 den bane. Denne sp\u00e6nding er st\u00f8j. St\u00f8jsp\u00e6nding er en af de interferenskilder, der kan skade systemets stabilitet. Derfor skal vi f\u00f8rst s\u00e6nke jordimpedansen for at s\u00e6nke jordst\u00f8jen.<\/p>\n\n\n\n

Som alle ved, er jorden returvejen for str\u00f8m. For ethvert signal skal signalet finde en vej tilbage til jorden, der har den laveste impedans. S\u00e5 det er meget vigtigt, hvordan vi h\u00e5ndterer den returvej.<\/p>\n\n\n\n

1 - Hvorfor returvejens st\u00f8rrelse og form er vigtig<\/h2>\n\n\n\n

For det f\u00f8rste ved vi fra formlen for str\u00e5ling, at str\u00e5lingsstyrken er proportional med loopets areal. Det betyder, at jo l\u00e6ngere returvejen er, og jo st\u00f8rre sl\u00f8jfen er, jo mere vil den str\u00e5le og forstyrre andre kredsl\u00f8b. S\u00e5 n\u00e5r du laver et printkort, skal du fors\u00f8ge at g\u00f8re str\u00f8m- og signalretursl\u00f8jferne s\u00e5 sm\u00e5 som muligt.<\/p>\n\n\n\n

For det andet hj\u00e6lper det at give et h\u00f8jhastighedssignal en god returvej med at bevare signalkvaliteten. Det skyldes, at den karakteristiske impedans for en transmissionslinje p\u00e5 printkortet normalt beregnes i forhold til et jordplan (eller et effektplan). Hvis der er et kontinuerligt jordplan i n\u00e6rheden af h\u00f8jhastighedssporet, vil sporets impedans forblive konstant. Hvis en del af sporet ikke har nogen jordreference i n\u00e6rheden, vil impedansen \u00e6ndre sig. Denne impedansdiskontinuitet vil skade signalintegriteten. Derfor skal man ved routing placere h\u00f8jhastighedsspor p\u00e5 lag t\u00e6t p\u00e5 et jordplan. Eller k\u00f8r et eller to jordspor parallelt ved siden af h\u00f8jhastighedssporet. Disse jordspor fungerer som et skjold og giver en n\u00e6rliggende returvej.<\/p>\n\n\n\n

For det tredje skal du s\u00e5 vidt muligt undg\u00e5 at f\u00f8re signaler p\u00e5 tv\u00e6rs af delte str\u00f8mforsyninger. Det skyldes, at n\u00e5r et signal krydser forskellige str\u00f8m- eller jordopdelinger, bliver dets returvej lang og kan opfange interferens. N\u00e5r det er sagt, er det ikke strengt forbudt for signaler med lav hastighed at krydse splits, fordi den interferens, de for\u00e5rsager, kan v\u00e6re lille. For h\u00f8j hastighed<\/a> signaler skal du v\u00e6re forsigtig og undg\u00e5 at krydse spalter, n\u00e5r du kan. Du kan ogs\u00e5 pr\u00f8ve at \u00e6ndre str\u00f8mlinjernes rutef\u00f8ring for at hj\u00e6lpe.<\/p>\n\n\n\n

Mange problemer med elektromagnetisk interferens kommer fra jorddesign. Jordpotentialet er referencen for hele kredsl\u00f8bet. Hvis jordpotentialet ikke er stabilt, kan kredsl\u00f8bet svigte. M\u00e5let med jorddesign er at holde jordpotentialet s\u00e5 stabilt som muligt og p\u00e5 den m\u00e5de fjerne interferens.<\/p>\n\n\n\n

Signaljordingsmetoder falder normalt i fire typer: flydende jord, enkeltpunktsjord, flerpunktsjord og blandet jord.<\/p>\n\n\n\n

\n\n\n\n

2 - Typer af jordforbindelse<\/h1>\n\n\n\n

A. Flydende jord<\/h2>\n\n\n\n

Form\u00e5l:<\/strong> Hold kredsl\u00f8bet eller enheden isoleret fra f\u00e6lles ledere, der kan for\u00e5rsage jordsl\u00f8jfer. Flydende jord g\u00f8r det ogs\u00e5 lettere at parre kredsl\u00f8b, der har forskellige potentialer.<\/p>\n\n\n\n

Ulempe:<\/strong> Det kan let ophobe statisk ladning og for\u00e5rsage st\u00e6rk elektrostatisk afladning (ESD).<\/p>\n\n\n\n

Kompromis:<\/strong> Tilf\u00f8j afladningsmodstande for at aflaste ladningen.<\/p>\n\n\n\n

\n\n\n\n

B. Enkeltpunktsjord<\/h2>\n\n\n\n

Enkeltpunktsjord betyder, at hvert kredsl\u00f8bs jord forbindes til den f\u00e6lles jord i samme punkt. Dette kan opdeles i serie-enkeltpunkt og parallel-enkeltpunkt. Brug ikke enkeltpunktsjord i systemer, hvor kredsl\u00f8b med h\u00f8j effekt og lav effekt blandes. Jordstr\u00f8mmene fra h\u00f8jeffektdelen vil p\u00e5virke laveffektdelene. Desuden b\u00f8r det mest f\u00f8lsomme kredsl\u00f8b placeres ved f\u00e6llespunktet, fordi det punkt har det mest stabile potentiale.<\/p>\n\n\n\n

Den st\u00f8rste fordel ved enkeltpunktsjord er, at der ikke er nogen jordsl\u00f8jfer, s\u00e5 designet er relativt enkelt. Men jordledningerne kan v\u00e6re lange, og jordimpedansen kan v\u00e6re stor.<\/p>\n\n\n\n

Enkeltpunktsjording kan g\u00f8res p\u00e5 to m\u00e5der:<\/p>\n\n\n\n

\"single-point<\/figure>\n\n\n\n
    \n
  1. Serie enkeltpunktsjord<\/strong> - Det er ganske enkelt. Men fordi der er en f\u00e6lles jordleder, vil der v\u00e6re en f\u00e6lles jordimpedans. Hvis kredsl\u00f8bene i serie har meget forskellige effektniveauer, vil de forstyrre hinanden kraftigt.<\/li>\n\n\n\n
  2. Parallel enkeltpunktsjord<\/strong> - Hvert kredsl\u00f8b f\u00f8rer en jordledning tilbage til det f\u00e6lles punkt separat. P\u00e5 den m\u00e5de undg\u00e5r man kobling p\u00e5 den f\u00e6lles jord. Men det kr\u00e6ver mange jordledninger og er ikke praktisk i mange tilf\u00e6lde.<\/li>\n<\/ol>\n\n\n\n

    I rigtige designs kan du bruge en blandet enkeltpunktstilgang, der bruger b\u00e5de serie og parallel. Placer kredsl\u00f8b, der ikke forstyrrer hinanden, p\u00e5 samme lag. Placer kredsl\u00f8b, der let forstyrrer hinanden, p\u00e5 forskellige lag. Forbind derefter jordlagene parallelt ved det f\u00e6lles punkt. (Den oprindelige tekst henviste til en figur her).<\/p>\n\n\n\n

    \"Mixed<\/figure>\n\n\n\n

    Brug det:<\/strong> Enkeltpunktsjording er velegnet til lave driftsfrekvenser (< 1 MHz).<\/p>\n\n\n\n

    Ulempe:<\/strong> Ikke god til h\u00f8jfrekvente situationer.<\/p>\n\n\n\n

    Enkeltpunktsjording er ikke egnet til h\u00f8jfrekvente kredsl\u00f8b, fordi jordledningerne er lange, og impedansen fra disse ledninger bliver uundg\u00e5elig. Overvej flerpunktsjording til h\u00f8jfrekvens.<\/p>\n\n\n\n

    \n\n\n\n

    C. Jordforbindelse med flere punkter<\/h2>\n\n\n\n

    Brug flerpunktsjording til h\u00f8je driftsfrekvenser (> 30 MHz). I en flerpunktsordning erstatter du individuelle jordsl\u00f8jfer med et jordplan, som hver del af kredsl\u00f8bet kan bruge. Den induktive reaktans i en jordledning vokser med frekvensen og med ledningens l\u00e6ngde. Ved h\u00f8je frekvenser \u00f8ges den f\u00e6lles jordimpedans. S\u00e5 du skal holde jordledningens l\u00e6ngde s\u00e5 kort som muligt.<\/p>\n\n\n\n

    N\u00e5r du bruger flerpunktsjord, skal du pr\u00f8ve at finde den n\u00e6rmeste jordoverflade med lav impedans at forbinde til. H\u00f8jfrekvente digitale kredsl\u00f8b har brug for parallel jordforbindelse. En enkel m\u00e5de at g\u00f8re det p\u00e5 er ved at bruge jordingsvias. N\u00e5r kredsl\u00f8b k\u00f8rer med h\u00f8j frekvens, kan man forestille sig, at et h\u00f8jfrekvent signal bev\u00e6ger sig langs et jordspor og p\u00e5virker n\u00e6rliggende kredsl\u00f8b. Det kan v\u00e6re meget slemt. S\u00e5 alle kredsl\u00f8b skal vende tilbage til jord i n\u00e6rheden. Jordsporene skal v\u00e6re korte. Det er derfor, der findes flerpunktsjord.<\/p>\n\n\n\n

    M\u00e5let med flerpunktsjord er at s\u00e6nke jordimpedansen. For at s\u00e6nke impedansen i et h\u00f8jfrekvent kredsl\u00f8b skal man overveje to ting: s\u00e6nke jordmodstanden og s\u00e6nke jordinduktansen.<\/p>\n\n\n\n

    \"Multipoint<\/figure>\n\n\n\n

    Metoder:<\/strong><\/p>\n\n\n\n

      \n
    1. Lavere ledermodstand.<\/strong> Fra forholdet mellem modstand og tv\u00e6rsnitsareal ved vi, at en for\u00f8gelse af lederens areal s\u00e6nker DC-modstanden. Men ved h\u00f8je frekvenser f\u00e5r skin-effekten str\u00f8mmen til at flyde t\u00e6t p\u00e5 ledernes overflade, s\u00e5 det har begr\u00e6nset effekt blot at \u00f8ge tv\u00e6rsnittet. Du kan overveje at bel\u00e6gge lederen med s\u00f8lv, fordi s\u00f8lv har bedre ledningsevne end mange andre metaller og kan reducere lederens modstand.<\/li>\n\n\n\n
    2. Lavere induktans.<\/strong> Den bedste m\u00e5de er at \u00f8ge jordarealet. I praksis giver korte jordledninger og et stort jordareal bedre anti-interferens.<\/li>\n<\/ol>\n\n\n\n

      P\u00e5 dette tidspunkt vil nogle m\u00e5ske sp\u00f8rge, hvad der t\u00e6ller som et h\u00f8jfrekvent kredsl\u00f8b. If\u00f8lge professor Yang Jishens bog Teknologi til elektromagnetisk kompatibilitet (EMC)<\/em>,<\/a> Normalt er kredsl\u00f8b under 1 MHz lavfrekvente og kan bruge enkeltpunktsjord. Kredsl\u00f8b over 10 MHz er h\u00f8jfrekvente og b\u00f8r bruge flerpunktsjording. Hvis den l\u00e6ngste jordledning er mindre end 1\/20 af b\u00f8lgel\u00e6ngden ved 1 MHz eller 10 MHz, kan enkeltpunktsjording stadig fungere. Ellers skal du bruge flerpunktsjording.<\/p>\n\n\n\n

      \n\n\n\n

      D. Blandet jord<\/h2>\n\n\n\n

      Hvis kredsl\u00f8bet har b\u00e5de h\u00f8j- og lavfrekvente signaler, er blandet jordforbindelse et godt valg. (Den oprindelige tekst henviste til en anden figur her).<\/p>\n\n\n\n

      Se p\u00e5 figuren og de to viste strukturer. For den f\u00f8rste struktur antages det, at den mest fungerer i et lavfrekvensmilj\u00f8. Ud fra formlen for kapacitiv reaktans Zc=12\u03c0fCZ_c = \\frac{1}{2\\pi f C}Zc=2\u03c0fC1 ved vi, at den kapacitive reaktans er stor ved lav frekvens, mens den er lille ved h\u00f8j frekvens. S\u00e5 i denne ledningsf\u00f8ring er jordforbindelsen \u00e5ben ved lav frekvens og n\u00e6sten lukket ved h\u00f8j frekvens. Denne ledningsf\u00f8ring kan undg\u00e5 jordsl\u00f8jfeinterferens.<\/p>\n\n\n\n

      \"Hybrid<\/figure>\n\n\n\n

      For den anden struktur antages det, at den mest fungerer i h\u00f8jfrekvensmilj\u00f8er. Fra formlen for induktiv reaktans ZL=2\u03c0fLZ_L = 2\\pi f LZL=2\u03c0fL ved vi, at den induktive reaktans er lille ved lav frekvens og stor ved h\u00f8j frekvens. S\u00e5 i denne ledningsf\u00f8ring opf\u00f8rer jordforbindelsen sig som en leder ved lav frekvens og er \u00e5ben ved h\u00f8j frekvens. Denne ledningsf\u00f8ring kan undg\u00e5 jordsl\u00f8jfestr\u00f8mme.<\/p>\n\n\n\n

      \n\n\n\n

      3 - M\u00e5der at forbinde forskellige grunde p\u00e5<\/h1>\n\n\n\n

      Hvis man ikke v\u00e6lger at bruge et helt plan som f\u00e6lles jord, og et modul har to jordnet, skal man opdele jordplanet. Det interagerer ofte med power-planet. M\u00e5derne at forbinde jord p\u00e5 er:<\/p>\n\n\n\n

        \n
      1. Almindeligt spor mellem grunde.<\/strong> Det giver en p\u00e5lidelig lavimpedansforbindelse til mellem- og lavfrekvente signaler.<\/li>\n\n\n\n
      2. H\u00f8j modstand mellem jordene.<\/strong> En stor modstand vil tillade en lille l\u00e6kstr\u00f8m, hvis der opst\u00e5r en sp\u00e6nding p\u00e5 tv\u00e6rs af den. Dette vil langsomt aflade ladning, indtil den potentielle forskel bliver nul. Brug dette til at binde flydende jordforbindelse forsigtigt fast.<\/li>\n\n\n\n
      3. Kondensator mellem jord.<\/strong> En kondensator blokerer DC, men lader AC passere. Brug den i systemer med flydende jord til at passere h\u00f8jfrekvent st\u00f8j, mens den blokerer for j\u00e6vnstr\u00f8m.<\/li>\n\n\n\n
      4. Ferritperle (magnetperle) mellem jordforbindelserne.<\/strong> En ferritperle fungerer som en frekvensafh\u00e6ngig modstand. Den ser resistiv ud ved h\u00f8je frekvenser. Brug den til svage signaljordinger med sm\u00e5, hurtige str\u00f8mspidser.<\/li>\n\n\n\n
      5. Induktor mellem jord.<\/strong> En induktor modst\u00e5r hurtige forandringer. Den kan udj\u00e6vne toppe og fylde dale. Brug den mellem jordforbindelser, der har store str\u00f8msvingninger.<\/li>\n\n\n\n
      6. Lille modstand mellem jord.<\/strong> En lille modstand tilf\u00f8jer d\u00e6mpning for at bremse hurtige \u00e6ndringer i jordstr\u00f8mmen. N\u00e5r str\u00f8mmen \u00e6ndrer sig hurtigt, g\u00f8r denne modstand den stigende flanke mindre stejl.<\/li>\n<\/ol>\n\n\n\n

        Alle disse valg giver mulighed for at kontrollere, hvordan st\u00f8j overf\u00f8res mellem underlagene.<\/p>\n\n\n\n

        \n\n\n\n

        4 - Analog jord og digital jord<\/h1>\n\n\n\n

        Analoge og digitale signaler har begge brug for at vende tilbage til jorden. Digitale signaler \u00e6ndrer sig hurtigt. De laver en masse st\u00f8j p\u00e5 den digitale jord. Analoge signaler har brug for en ren jordreference for at fungere godt. Hvis analog og digital jord blandes, vil st\u00f8jen fra den digitale jord p\u00e5virke de analoge signaler.<\/p>\n\n\n\n

        Generelt skal du adskille analog og digital jord. Forbind dem derefter med et tyndt spor eller i et enkelt punkt. Hovedid\u00e9en er at forhindre digital jordst\u00f8j i at komme ind i den analoge jord.<\/p>\n\n\n\n

        \n\n\n\n

        5 - Stjernejord<\/h1>\n\n\n\n

        Teorien bag stjernejording er, at der er \u00e9t punkt i kredsl\u00f8bet, som fungerer som reference for alle sp\u00e6ndinger. Dette er stjernepunktet. Du kan forestille dig det: Mange ledninger l\u00f8ber fra et f\u00e6lles punkt i et radialt m\u00f8nster som str\u00e5lerne p\u00e5 en stjerne. Stjernepunktet ser m\u00e5ske ikke ud som en stjerne p\u00e5 printet. Det kan v\u00e6re et punkt p\u00e5 jordoverfladen. En vigtig egenskab ved et stjernejordingssystem er, at alle sp\u00e6ndinger m\u00e5les i forhold til det samme punkt p\u00e5 jordingsnetv\u00e6rket, ikke en eller anden usikker \u201cjord\u201d-reference.<\/p>\n\n\n\n

        \n\n\n\n

        6 - S\u00e5dan jordes sk\u00e6rme<\/h1>\n\n\n\n

        Sk\u00e6rmen p\u00e5 et sk\u00e6rmet kabel og kablets afl\u00f8bsledning skal forbindes til kortets interfacejord, ikke til signaljorden. Det skyldes, at signaljorden ofte har mange st\u00f8jsp\u00e6ndinger. Hvis sk\u00e6rmen forbindes til den st\u00f8jende signaljord, vil st\u00f8jsp\u00e6ndingen drive common-mode-str\u00f8m p\u00e5 sk\u00e6rmen og for\u00e5rsage ekstern interferens. D\u00e5rligt kabeldesign og d\u00e5rlig sk\u00e6rmjording er ofte den st\u00f8rste kilde til EMI.<\/p>\n\n\n\n

        \n\n\n\n

        Sammenfatning<\/h1>\n\n\n\n

        I praksis skal du v\u00e6lge den jordforbindelse, der passer til driftsmilj\u00f8et. Et godt valg kan undg\u00e5 interferens og give den bedste kredsl\u00f8bsydelse.<\/p>\n\n\n\n

          \n
        • Hold retursl\u00f8jferne sm\u00e5 for at reducere str\u00e5lingen.<\/li>\n\n\n\n
        • Hold h\u00f8jhastighedsspor ved siden af kontinuerlige jordplaner for at f\u00e5 en stabil impedans.<\/li>\n\n\n\n
        • Undg\u00e5 at krydse power plane splits, hvor det er muligt.<\/li>\n\n\n\n
        • Til lavfrekvente systemer (< 1 MHz) fungerer enkeltpunktsjording ofte.<\/li>\n\n\n\n
        • Til h\u00f8jfrekvente systemer (> 10 MHz) skal man bruge flerpunktsjording og korte jordingsveje med masser af returareal.<\/li>\n\n\n\n
        • For blandede systemer skal du bruge en hybrid tilgang med kondensatorer, induktorer, modstande, ferritperler eller sm\u00e5 spor for at kontrollere koblingen.<\/li>\n\n\n\n
        • Adskil analog og digital jord, og forbind dem omhyggeligt.<\/li>\n\n\n\n
        • Bind kabelsk\u00e6rme til stikjord eller chassisjord, ikke til st\u00f8jende signaljord.<\/li>\n<\/ul>\n\n\n\n

          Disse trin vil hj\u00e6lpe med at s\u00e6nke jordimpedansen og reducere jordst\u00f8j, s\u00e5 systemet bliver mere stabilt og p\u00e5lideligt.<\/p>\n\n\n\n
