Yintoni i I-PCB ye-Multilayer?

I-PCB ye-multilayer ichazwa njenge-PCB eyenziwe ngamanqanaba amathathu okanye nangaphezulu e-foil yokuhambisa ubhedu. Zijongeka ngathi ziileya zebhodi yesekethe enamacala amabini, i-laminated kwaye incamathelene kunye, eneendlela ezininzi zokugquma phakathi kwazo. Isakhiwo sonke sicwangcisiwe ukuze iileya ezimbini zibekwe kwicala elingaphezulu lePCB ukunxibelelana nokusingqongileyo. Lonke unxibelelwano lombane phakathi kwamanqanaba lwenziwa ngemingxunya enje nge-electroplated ngemingxunya, imingxunya engaboniyo kunye nemingxunya engcwatyelweyo. Le ndlela ingasetyenziselwa ukuvelisa ii-PCBS ezinzima kakhulu ngobukhulu obuhlukeneyo.

Kutheni ii-PCBS ezininzi zisetyenziswa kangaka

Ii-PCBS ze-Multilayer ziye zabakho ngenxa yeenguqu ezitshintsha rhoqo kumzi mveliso we-elektroniki. Ixesha elingaphezulu, imisebenzi yezixhobo ze-elektroniki ziye zisiba nzima ngakumbi, zifuna iiPCBS ezinzima. Ngelishwa, ii-PCB zikhawulelwe yimicimbi enje ngengxolo, amandla ombane, kunye necrosstalk, ke ngoko kukho iingxaki ezithile kuyilo ekufuneka zilandelwe. Olu luqwalaselo loyilo lwenze ukuba kube nzima ukufumana intsebenzo eyonelisayo kwi-PCBS esecaleni okanye macala omabini-yiyo loo nto kuzalwa ii-PCBS ezininzi.

Ukudibanisa amandla ee-PCBS ezibekwa kabini kule fomathi liqhezu lobungakanani kuphela, kwaye ii-PCBS ezininzi ezahlulahlulayo ziya zisanda ngokuthandwa kwi-elektroniki. Ziza ngobukhulu obahlukeneyo kunye nobukhulu ukuhlangabezana neemfuno zezicelo zazo ezandisiweyo, ngokwahluka ukusuka kwi-4 ukuya kwi-12 yamanqanaba. Inani lemiqolo lihlala nokuba kungenxa yemigangatho engaqhelekanga inokubangela iingxaki kwisekethe, ezinje ngokujijisana, kwaye azibizi mali ininzi ukuvelisa. Uninzi lwezicelo zifuna iileya ezine ukuya kwezisibhozo, kodwa usetyenziso olufana nezixhobo eziphathwayo kunye nee-smartphones zihlala zisebenzisa ii-12, ngelixa abanye abavelisi bePCB benamandla okuvelisa kufutshane ne-100. Nangona kunjalo, ii-PCBS ezininzi ezinobumba obuninzi zinqabile kuba zibiza kakhulu.

Kutheni ii-PCBS ezininzi zisetyenziswa kangaka
