I-foil yethusi ye-PCB

Ngenxa yokwanda kokusetshenziswa kwezinto zikagesi, isidingo salezi zisetshenziswa besilokhu siphezulu emakethe.Lezi zixhobo okwamanje zisizungezile njengoba sincike kakhulu kuzo ngezinhloso ezahlukene.Ngalesi sizathu, ngibheja ukuthi uhlangabezane nedivayisi ye-elekthronikhi noma ujwayele ukuzisebenzisa ekhaya.Uma usebenzisa lezi zisetshenziswa, ungase uzibuze ukuthi izingxenye zedivayisi ye-elekthronikhi zinezintambo kanjani, zisebenza kanjani, nokuthi idivayisi ingaxhunywa kanjani kwezinye izinto.Izinto zikagesi esizisebenzisayo ekhaya zenziwe ngezinto ezingawuhambisi ugesi.Anezindlela ezibhalwe ngezinto zethusi eziqhutshwayo endaweni yazo, okuvumela isignali ukuthi igeleze ngaphakathi kwedivayisi lapho ingaphansi kokusebenza.

Ngakho-ke, ubuchwepheshe be-PCB busekelwe ekuqondeni ukusebenza kwamadivaysi kagesi.I-PCB ihlale isetshenziswa kakhulu kumishini kagesi eyenzelwe imidiya.Kodwa-ke, esizukulwaneni sanamuhla, zisetshenziswa kuwo wonke amadivaysi kagesi.Ngalesi sizathu, asikho isisetshenziswa sikagesi esingasebenza ngaphandle kwe-PCB.Le bhulogi igxile kwi-foil yethusi ye-PCB, kanye nendima edlalwa yi-ucwecwe lwethusiembonini yebhodi lesekethe.

I-Printed Circuit Board (PCB) Technology

Ama-PCB ayimigudu ehambisa ugesi njengokulandela umkhondo namathrekhi, anamethwe ngefoyili yethusi.Lokhu kubenza baxhumane futhi basekele ezinye izingxenye ze-elekthronikhi ezixhunywe ngomshini kudivayisi.Ngalesi sizathu, umsebenzi oyinhloko walawa ma-PCB emishinini kagesi ukunikeza ukwesekwa ezindleleni.Ezimweni eziningi, izinto ezifana ne-fiberglass namapulasitiki zibamba kalula i-foil yethusi kumjikelezo.I-foil yethusi ku-PCB imvamisa i-laminated nge-non-conductive substrate.Ku-PCB, ucwecwe lwethusi ludlala indima ebalulekile ekuvumeleni ukuhamba kukagesi phakathi kwezingxenye ezihlukahlukene zedivayisi, ngaleyo ndlela kusekelwe ukuxhumana kwazo.

Amasosha ahlala exhuma ngokuphumelelayo phakathi kwe-PCB surface kanye nezinto zikagesi.Lawa ma-solder enziwa kusetshenziswa insimbi eyenza ibe ingcina eqinile;ngakho-ke, zithembekile ekunikezeni ukwesekwa kwemishini ezingxenyeni.Umzila we-PCB uvamise ukuhlanganiswa ngezendlalelo eziningi zezinto ezihlukene ezifana nesikrini sikasilika nezinsimbi ezinamekwe nge-substrate ukuzenza i-PCB.

Indima ye-copper foil embonini yebhodi lesifunda

Ubuchwepheshe obusha obuthrendayo namuhla busho ukuthi asikho isisetshenziswa sikagesi esingasebenza ngaphandle kwe-PCB.I-PCB, ngakolunye uhlangothi, ithembele kakhulu ethusi kunezinye izingxenye.Lokhu kungenxa yokuthi ithusi lisiza ekudaleni iminonjana ehlanganisa zonke izingxenye ze-PCB ukuvumela ukushaja ngaphakathi kwedivayisi.Imikhondo ingachazwa njengemithambo yegazi kuhlaka lwamathambo e-PCB.Ngakho-ke i-PCB ayikwazi ukusebenza lapho iminonjana ingekho.Uma i-PCB yehluleka ukusebenza, idivayisi ye-elekthronikhi izolahlekelwa umqondo wayo, iyenze ingabi namsebenzi.Ngakho-ke, ithusi liyingxenye eyinhloko ye-PCB ye-conductivity.I-foil yethusi ku-PCB iqinisekisa ukugeleza okuqhubekayo kwamasignali ngaphandle kokuphazamiseka.

Izinto zethusi zihlale zaziwa ukuthi zine-conductivity ephezulu kunezinye izinto ngenxa yama-electron amahhala akhona egobolondweni layo.Ama-electron akhululekile ukuhamba ngaphandle kokumelana nanoma iyiphi i-athomu eyenza ithusi ekwazi ukuthwala amashaji kagesi anyakazayo ngaphandle kokulahlekelwa noma ukuphazamiseka kumasignali.Ithusi, elenza i-electrolyte engalungile, lihlala lisetshenziswa kuma-PCB njengongqimba lokuqala.Ngenxa yokuthi ithusi alithinteki kangako umoya-mpilo ongaphezulu, lingasetshenziswa izinhlobo eziningana zama-substrates, izingqimba ezivikelayo, nezinsimbi.Uma isetshenziswa nalawa ma-substrates, yakha amaphethini ahlukene kusekethe, ikakhulukazi ngemuva kokuqoshwa.Lokhu kwenzeka njalo ngenxa yekhono lethusi lokwenza isibopho esiphelele ngezendlalelo zokuvikela ezisetshenziselwa ukwenza i-PCB.

Ngokuvamile kuba nezingqimba eziyisithupha ze-PCB ezakhiwe, kuzo izingqimba ezine ziku-PCB.Ezinye izendlalelo ezimbili zivame ukungezwa kuphaneli yangaphakathi.Ngalesi sizathu, lezi zingqimba ezimbili ezokusetshenziswa kwangaphakathi, kukhona futhi ezimbili ezizosetshenziswa ngaphandle, futhi ekugcineni, ezimbili ezisele kuzo zonke izingqimba eziyisithupha ezokuthuthukisa amaphaneli ngaphakathi kwe-PCB.

Isiphetho

I-copper foiliyingxenye ebalulekile ye-PCB evumela ukugeleza kwamashaji kagesi ngaphandle kokuphazamiseka.Ine-conductivity ephezulu futhi yakha ngokuphelele isibopho esiqinile ngezinto ezihlukene zokuvikela ezisetshenziswa ebhodini lesifunda le-PCB.Ngalesi sizathu, i-PCB incike ku-foil yethusi ukuthi isebenze njengoba yenza ukuxhuma kwamathambo e-PCB kusebenze kahle.
