Ukubaluleka kwama-PCB avame kakhulu ekukhiqizweni kwezinto zikagesi
Njengoba izinto zobuchwepheshe ziqhubeka nokuthuthuka ngobunzima futhi zifuna ngokushesha izinga lokudluliswa kwesignalis, ama-PCB avame kakhulu abe yingxenye ebalulekile ekuthuthukisweni kwe uhlelo lokusebenza olusebenza kahle kakhuluskuyo yonke imboni yokukhiqiza.
Imvamisa ephezulu ibhodi lesifunda eliphrintiweAma-PCB (ama-PCB) asebaluleke kakhulu ekukhiqizweni kwezinto zikagesi, enikeza izici eziningi ezibalulekile. Empeleni, ama-PCB asebenza kakhulu adlulisa ngempumelelo igagasi likagesingokulahlekelwa okuncane kanye nokuqinisekisa ukugeleza kwesignali yesivinini esikhuluIzakhiwo ezibalulekile ezihlotshaniswa nama-PCB asebenza imvamisa ephezulu zifaka:
Phansi Isici SokushabalalisaAma-PCB avame kakhulu avame ukubonisa isici sokushabalalisa esisukela ku-0.0019 kuya ku-0.025, okuqinisekisa ukuthi kuncane kakhulu ukulahleka kwesignali kanye nokugcina izinga lokudluliswa kwesignalis.
Phansi I-Dielectric Constant: Lawa ma-PCB anesilinganiselo se-dielectric esiphansi nesizinzile, okwenza kube lula ukushelela ukudluliswa kwemvamisakanye nokunciphisa ukulibaziseka kwesignali.
Ukumelana Namakhemikhali: Amandla ama-PCB avame kakhulu okumelana nokuchayeka kumakhemikhali abaluleke kakhulu, okuqinisekisa ukumelana nokugqwala kanye nokufaneleka ezindaweni ezichayeke kakhulu kumakhemikhali.
Ukumuncwa Okuphansi Komswakama: Njengoba izinga lokumuncwa kwamanzi liphansi, ama-PCB avame ukusetshenziswa kakhulu afaneleka kahle ezindaweni ezimanzi nezinomswakama.
Phansi Ukuqina Okulinganayo: Ama-PCB avame kakhulu ayaziwa ngokugcina usayizi wawo futhi angathinteki yizinguquko zokushisa kwemvelo.
Ngenxa yalezi zici, ukusetshenziswa kwazo kusakazeke kabanzi. Kodwa-ke, abaklami be-PCB kumele baqinisekise ukuthi izinyathelo ezilandelayo zilandelwa ngokucophelela lapho kuklanywa ama-PCB asebenza kakhulu:
Nquma i-PCB imvamisa yesignali: Kubalulekile ukusungula izidingo ze-voltage namandla, ukuhlukanisa noma yikuphi indiza yamandlas, futhi uhlole ukuhambisana kwezimpawu ezahlukene. Ngaphezu kwalokho, ukunciphisa amazinga okubekezelelana nokunciphisa amazinga omsindo kuyizinto ezibalulekile okufanele uzicabangele.
Ibhodi elihlanganisiweukuhlela: Izidingo ze- isendlalelo se-stackupkumele kuhlelwe ngokucophelela, kucatshangelwa izinto ezithile kanye nokulinganiselwa kwazo.
Ukuhlela phansi: I-PCB kufanele ihlukaniswe ngezigaba, kube nokuhlukaniswa okufanele ezindaweni eziqukethe izingxenye zedijithali neze-analog ukuvimbela ukuphazamiseka.
Amandla kanye indiza yasemhlabenis: Uma ukwakheka kwe-PCB sekuchaziwe, ukuqonda uhlelo lomhlabathi kubalulekile. Ukuhlukanisa indiza yomhlabathi kubalulekile, futhi ukufaka i-resistor kanye nomkhondo wesiginali ukuze kuthuthukiswe indlela yokubuya kubalulekile.
Nciphisa usayizi wamaphethini omhlaba: Ama-PCB avame kakhulu avame ukuba nama-pad amancane. Ukunciphisa isikhala kusiza ekunciphiseni amandla okusebenzisa izimuncagazifuthi kwandisa amandla omshini.
Indlela isignali yemvamisas: Izimpawu zemvamisa ephezulu zaziwa ngokukhiqiza imisebe ephezulu. Ukuhambisa ngempumelelo izimpawu zemvamisa kungavimbela ukuphazamiseka phakathi kwezibonakaliso.
Sebenzisa umthetho we-3W: Ukunamathela emthethweni we-3W kuqinisekisa ukuthi ubuqotho besiginali buyagcinwa, okwakha umehluko phakathi kwezimpawu kanye nokunciphisa umphumela wokuxhuma.
Sebenzisa umthetho wama-20H: Ukuxhumanisa phakathi kwezindiza zasemhlabeni nezamandla kungaba yingozi ekwakhiweni kwakho. Umthetho wama-20H uqinisekisa ukuthi ubukhulu phakathi kwamandla aseduze nezindiza zasemhlabeni bukhulu kunezindiza zamandla.
Ukusetshenziswa kwama-PCB avame kakhulu
Ukusetshenziswa kwama-PCB asebenza kakhulu kuyanda, kanti izinhlelo zokusebenza zifaka:
Izinhlelo zokuxhumana kumadivayisi okuhlunga, i-amplifiers, isiteshi sokukhuthazas, kanye umamukelis.
Izicelo zempi zokukhiqiza izinhlamvu nezibhamu.
Uhlelo lwe-radareziqondisa izindiza futhi zivimbele izingozi.
Amadivayisi okuxilonga nokuqapha abalulekile embonini yezokwelapha.
Ekuphetheni
Ama-PCB asebenza kakhulu abalulekile ekukhiqizweni kwama-PCB kagesi, anikeza izici eziqinile ezenza kube ukukhetha okuthandwayo kwemishini kagesi. Adlala indima ebalulekile ekusetshenzisweni kokusebenza okuphezulu futhi akulungele ukuba abaluleke nakakhulu ngenxa yobunzima obukhulayo bemishini kagesi kanye nesidingo samazinga okudlulisa amasignali ngokushesha.
