Dizajn \u0161tampane plo\u010dice zasnovan je na shematskom dijagramu kola kako bi se ostvarile funkcije koje je projektant kola zahtijevao. Dizajn \u0161tampane plo\u010dice<\/a> To je vrlo tehni\u010dki posao i zahtijeva mnogo godina akumulacije iskustva. Sljede\u0107i proizvo\u0111a\u010di tiskanih plo\u010dica sa\u017eeli su nekoliko uobi\u010dajenih problema u dizajnu PCB-a za va\u0161u referencu.<\/p>\n\n\n\n

Prvo. Preklapanje jastu\u010di\u0107a<\/h2>\n\n\n\n
    \n
  1. Preklapanje padova (osim povr\u0161inskih padova) zna\u010di preklapanje rupa. Tokom procesa bu\u0161enja, svrdlo \u0107e se slomiti zbog vi\u0161estrukog bu\u0161enja na istom mjestu, \u0161to \u0107e dovesti do o\u0161te\u0107enja rupa.<\/li>\n\n\n\n
  2. Dvije rupe na vi\u0161eslojnoj plo\u010di se preklapaju. Na primjer, jedna rupa je izolacijski disk, a druga je kontaktna plo\u010dica (flower pad), pa \u0107e se nakon iscrtavanja filma film pojaviti kao izolacijski disk, \u0161to dovodi do otpada.<\/li>\n<\/ol>\n\n\n\n

    Drugo. Zloupotreba grafi\u010dkog sloja<\/h2>\n\n\n\n
      \n
    1. Na nekim grafi\u010dkim slojevima napravljene su neke beskorisne veze. Izvorno je plo\u010da imala \u010detiri sloja, ali je projektovana s vi\u0161e od pet slojeva o\u017ei\u010denja, \u0161to je izazvalo nesporazume.<\/li>\n\n\n\n
    2. Sprije\u010dite probleme tokom dizajna. Uzmite Protel softver kao primjer za crtanje linija na svakom sloju pomo\u0107u Board sloja i koristite Board sloj za ozna\u010davanje linija. Na taj na\u010din, prilikom izvo\u0111enja lakih crtanja, budu\u0107i da Board sloj nije odabran, on se izostavlja. Povezanost se prekida ili mo\u017ee do\u0107i do kratkog spoja zbog odabira linije za ozna\u010davanje u Board sloju, pa se tokom dizajna odr\u017eava integritet i jasno\u0107a grafi\u010dkog sloja.<\/li>\n\n\n\n
    3. Kr\u0161enje konvencionalnog dizajna, kao \u0161to je dizajn povr\u0161ine komponente u donjem sloju i dizajn zavarene povr\u0161ine u gornjem sloju, uzrokuje neugodnosti.<\/li>\n<\/ol>\n\n\n\n

      Tre\u0107e. Nasumi\u010dno raspore\u0111ivanje likova<\/h2>\n\n\n\n
        \n
      1. SMD lemna plo\u010dica na poklopcu za znakove predstavlja smetnju pri testiranju kontinuiteta \u0161tampane plo\u010de i pri lemljenju komponenti.<\/li>\n\n\n\n
      2. Dizajn karaktera je premalen, \u0161to uzrokuje pote\u0161ko\u0107e pri sitotisku, a ako je prevelik, karaktere \u0107e se preklapati i bit \u0107e ih te\u0161ko razlikovati.<\/li>\n<\/ol>\n\n\n\n

        \u010cetvrto. Postavljanje otvora jednostrane podloge<\/h2>\n\n\n\n
          \n
        1. Jednostrane plo\u010dice obi\u010dno se ne bu\u0161e. Ako je potrebno ozna\u010diti bu\u0161enje, promjer rupe treba biti postavljen na nulu. Ako se unese numeri\u010dka vrijednost, pri generiranju podataka za bu\u0161enje koordinate rupe pojavljuju se na toj poziciji i nastaje problem.<\/li>\n\n\n\n
        2. Jednostrane podloge treba posebno ozna\u010diti ako su izbu\u0161ene.<\/li>\n<\/ol>\n\n\n\n

          Pet. Koristite blokove za punjenje za crtanje jastu\u010di\u0107a<\/h2>\n\n\n\n

          Pads sa punilnim blokovima mogu pro\u0107i DRC inspekciju pri projektovanju kola, ali to nije dobro za obradu. Stoga sli\u010dni pads ne mogu direktno generisati podatke za masku za lemljenje. Kada se nanese maska za lemljenje, podru\u010dje punilnog bloka bit \u0107e prekriveno maskom za lemljenje, \u0161to ote\u017eava lemljenje ure\u0111aja.<\/p>\n\n\n\n
