Isicelo
Ibhodi yesekethe enamacala amabini ubukhulu becala ukusombulula uyilo oluntsonkothileyo lwesekethe kunye nemida yendawo, kumacala omabini ebhodi efakwe amacandelo, i-wiri-layer okanye i-wiring ye-multi-layer. , iiamplifiers, iinkqubo zokukhanyisa, kunye needashbhodi zeemoto.IiPCB ezinamacala amabini zezona zilungele usetyenziso lwetekhnoloji ephezulu, iisekethe zombane ezihlangeneyo, kunye neesekethe ezintsonkothileyo.Ukusetyenziswa kwayo kubanzi kakhulu kwaye ixabiso liphantsi.
Ii-FAQs
I-2-layer PCB lubhedu oluqatywe kumacala omabini kunye ne-insulating layer phakathi.Inamacandelo kumacala omabini ebhodi, yiyo loo nto ikwabizwa ngokuba yiPCB enamacala amabini.Zenziwe ngokudibanisa iileya ezimbini zobhedu kunye, kunye ne-dielectric material phakathi.
Ungaqikelela ukuba yintoni umahluko obonakalayo phakathi kwe-2 umaleko we-PCB kunye ne-4 umaleko we-PCB ngokwamagama abo.2 umaleko PCB uye imikhondo ezimbini emacaleni kunye umaleko phezulu nasezantsi, ngelixa 4 umaleko PCB has 4 umaleko.Ukuba une ukuqonda ngcono iintlobo ezimbini iibhodi PCB, uya kufumanisa ukuba kukho iiyantlukwano ezininzi ngendlela zakhiwe kunye nendlela yokusebenza.
Imigca yePCB enecala elinye ikhona kwicala elinye kuphela, ngelixa iiPCB ezinamacala amabini zinemizila macala omabini anomaleko aphezulu nasezantsi.Amacandelo kunye nobhedu oluqhubekileyo lufakwe kumacala omabini e-PCB enamacala amabini, kwaye oku kukhokelela ekudibaneni okanye ukudlulana komkhondo.
Ewe, vele usithumelele ifayile yakho yegerber.

I2 umaleko wePCB(i-PCB enamacala amabini) yibhodi yesekethe eprintiweyo enobhedu olufakwe kumacala omabini, phezulu nasezantsi.Kukho i-insulating layer phakathi, esetyenziswa ngokuqhelekileyo ibhodi yesekethe eprintiweyo.Omabini amacala anokuba yi-layout kunye ne-soldered, enciphisa kakhulu ubunzima bokucwangcisa, ngoko isetyenziswa ngokubanzi.
Ukusebenzisa iisekethe kumacala omabini, kufuneka kubekho uxhulumaniso lwesekethe olufanelekileyo phakathi kwamacala amabini."Iibhulorho" phakathi kweesekethe ezinjalo zibizwa ngokuba yi-vias.Ukudlula ngumngxuma omncinci kwibhodi yePCB ezaliswe okanye iqatywe ngentsimbi, enokuthi idityaniswe neesekethe kumacala omabini.Ngenxa yokuba indawo yebhodi enecala eliphindwe kabini iphindwe kabini kunaleyo yebhodi enye, ibhodi enecala eliphindwe kabini isombulula ubunzima bebhodi enye ngenxa yokwakheka okudibeneyo (inokudityaniswa kwelinye icala. ngemingxunya), kwaye ifaneleke ngakumbi kwiisekethe ezintsonkothileyo kunebhodi enecala elinye.
Sifuna iimveliso ze-elektroniki kunye nokusebenza okuphezulu, ubungakanani obuncinci, kunye nemisebenzi emininzi, ekhuthaza ukuphuhliswa kokuveliswa kwebhodi yesekethe eprintiweyo ukuba ibe lula, incinci, imfutshane, kwaye incinci.Ngesithuba esilinganiselweyo, imisebenzi emininzi inokufezekiswa, ukuxinana kwesakhiwo kuye kwaba mkhulu, kwaye ububanzi bomngxuma buncinci.Ubuncinci bomngxuma womthamo wokomba womatshini wehlile ukusuka kwi-0.4mm ukuya kwi-0.2mm okanye nangaphantsi.Idayimitha yomngxuma yePTH iya isiba ncinci kwaye incinci.Umgangatho we-PTH (iPlated through Hole) apho i-layer-to-layer interconnection ixhomekeke ngokuthe ngqo ekuthembekeni kwebhodi yesekethe eprintiweyo.
