Uyini umsebenzi we-PCB eboshwe ngethusi?

PCB wesifunda ibhodi kuzo zonke izinhlobo zemishini kagesi kanye nezinsimbi kungabonakala yonke indawo, ukuthembeka kwebhodi lesifunda kuyisiqinisekiso esibalulekile sokuqinisekisa ukusebenza okujwayelekile kwemisebenzi ehlukahlukene, kepha kumabhodi amaningi wesifunda sivame ukubona indawo enkulu enkulu yokumboza ithusi, idizayini yesifunda ibhodi elinendawo enkulu yokumboza ithusi.
Ngokuvamile kunezinhlobo ezimbili zezembatho ezinkulu zethusi, uhlobo olulodwa ukushisa ukushabalalisa, ngenxa yokwanda kwamandla wesekethe wamandla kukhulu kakhulu, ngakho-ke ngaphezu kokungeza izinto ezidingekayo zokupholisa, njengokushisa kokushisa, ukupholisa fan, njll. kodwa kwebhodi elithile lesifunda kepha lokhu akwanele, uma kumane nje kushise ukushisa komphumela, ngasikhathi sinye ekwandeni kwendawo yocwecwe lwethusi ukusiza ukukhulisa ungqimba lwe-welding, Futhi engeza ithini ukuqinisa ukushabalalisa ukushisa.
Kufanele kuqashelwe ukuthi ngenxa yengubo enkulu yethusi eguqulwe isikhathi eside ukushisa noma i-PCB, i-PCB enezinga eliphansi lokunamathisela ucwecwe lwethusi, kancane kancane elinqwabelene ngaphakathi kwegesi ephunyukayo ayikwazi ukuphuma, ngenxa yokushisa okushisayo okubandayo , ingenza ucwecwe lwethusi bese iwa phansi, ngakho-ke uma indawo egqoke ithusi inkulu kakhulu ukubheka ukuthi ngabe ikhona yini le nkinga, Ikakhulukazi lapho izinga lokushisa liphakeme ngokwengeziwe, ingafakwa iwindi noma yakhelwe njengenethiwekhi yegridi.

Okunye ukukhulisa isekethe ye-anti-jamming, ngenxa yokuthi ithusi elikhulu linganciphisa i-impedance yomhlaba, linganciphisa isignali yokuphazamiseka kokuvikela, ikakhulukazi kwabanye ijubane PCB, ngaphezu komugqa oqinile wokugxila ngangokunokwenzeka, ibhodi lesifunda ngaphezu kwezingxenye ezidingekayo kufanele ligxishwe, okungukuthi “umhlabathi”, ukuze sikwazi ukunciphisa ngempumelelo ukuminyaniswa kwezinambuzane, ngasikhathi sinye, Ukugxila kwendawo enkulu kunganciphisa ngempumelelo imisebe yomsindo, njll. Isibonelo, kwamanye ama-chip chip circuits, ulayini phansi usakazeke nxazonke kukhiye ngamunye, okunciphisa ikhono lokulwa nokuphazamiseka
