I-PCB yoMaleko omnye Vs iMulti Layer PCB – Izinto eziluncedo, izinto ezingeloncedo, uYilo kunye neNkqubo yokuVelisa.
Ngaphambiliukuyila ibhodi yesekethe eprintiweyo, kufuneka wenze isigqibo sokuba usebenzise umaleko omnye okanye iPCB enamaleko amaninzi. Zombini iintlobo zoyilo zisetyenziswa kwizixhobo ezininzi zemihla ngemihla. Uhlobo lweprojekthi oyisebenzisela ibhodi iya kugqiba ukuba yeyiphi eyona ikulungeleyo. Iibhodi ze-Multi-layer zixhaphake kakhulu kwizixhobo eziyinkimbinkimbi, ngelixa iibhodi ezinoluhlu olulodwa zingasetyenziselwa izixhobo ezilula. Eli nqaku liza kukunceda uqonde umahluko kwaye ukhethe uhlobo olufanelekileyo lweprojekthi yakho.
Ngokusekwe kumagama ezi PCBs, ungaqikelela ukuba yintoni umahluko. Ibhodi yebhodi enye inomaleko omnye wesiseko (eyaziwa nangokuthi i-substrate), ngelixa iibhodi ze-multi-layer ziqulethe iileyile ezininzi. Xa uzivavanya ngokusondeleyo, uya kuqaphela iiyantlukwano ezininzi kwindlela ezi bhodi zakhiwe kwaye zisebenza ngayo.
Ukuba unomdla wokufunda ngakumbi malunga nezi ntlobo zimbini zePCB, qhubeka ufunda!
Yintoni i-PCB yoLeya olunye?
Iibhodi ezinecala elinye zikwabizwa ngokuba ziibhodi ezicalanye. Zineenxalenye kwicala elinye kunye nepateni yomqhubi kwelinye. Ezi bhodi zinomqolo omnye wezinto eziphathekayo (ngokuqhelekileyo ubhedu). Ibhodi ye-single-layer iqukethe i-substrate, i-conductive metal layers, i-solder layer ekhuselayo, kunye nesikrini sesilika. Iibhodi ezinoluhlu olunye zifumaneka kwizixhobo ezininzi zombane ezilula.
Izinto eziluncedo kwi-PCB yoMaleko omnye
