I-foil yethusi ye-PCB

Ngenxa yokusetshenziswa okwandisiwe kwamadivayisi kagesi, isidingo sala madivayisi besilokhu siphezulu emakethe. Lawa madivayisi okwamanje asizungezile njengoba sithembele kakhulu kuwo ngezinjongo ezahlukene. Ngenxa yalesi sizathu, ngiyaqiniseka ukuthi uhlangane nedivayisi kagesi noma uvame ukuyisebenzisa ekhaya. Uma usebenzisa la madivayisi, ungase uzibuze ukuthi izingxenye zedivayisi kagesi zixhunywe kanjani, ukuthi isebenza kanjani, nokuthi idivayisi ingaxhunywa kanjani kwezinye izinto. Amadivayisi kagesi esiwasebenzisa ekhaya enziwe ngezinto ezingahambisi ugesi. Anezindlela eziqoshwe ngezinto zethusi ezihambisa ugesi ebusweni bawo, okuvumela isignali ukuthi igeleze ngaphakathi kwedivayisi uma isebenza.

Ngakho-ke, ubuchwepheshe be-PCB busekelwe ekuqondeni ukusebenza kwamadivayisi kagesi. I-PCB ihlala isetshenziswa kakhulu kumadivayisi kagesi aklanyelwe imidiya. Kodwa-ke, esizukulwaneni sanamuhla, asetshenziswa kuwo wonke amadivayisi kagesi. Ngenxa yalesi sizathu, akukho divayisi kagesi engasebenza ngaphandle kwe-PCB. Le bhulogi igxile ku-foil yethusi ye-PCB, kanye nendima edlalwa yi-i-foil yethusiembonini yamabhodi wesekethe.

Ubuchwepheshe beBhodi Yesekethe Ephrintiwe (i-PCB)

Ama-PCB ayizindlela ezihambisa ugesi njengemikhondo nemizila, ehlanganiswe nge-foil yethusi. Lokhu kuwenza axhumane futhi asekele ezinye izingxenye ze-elekthronikhi ezixhunywe ngomshini kudivayisi. Ngenxa yalesi sizathu, umsebenzi oyinhloko walezi PCB kumadivayisi kagesi ukunikeza ukwesekwa ezindleleni. Ezimweni eziningi, izinto ezifana ne-fiberglass nepulasitiki zibamba kalula i-foil yethusi esiketheni. I-foil yethusi ku-PCB ivame ukumbozwa nge-substrate engahambisani nogesi. Ku-PCB, i-foil yethusi idlala indima ebalulekile ekuvumeleni ukugeleza kukagesi phakathi kwezingxenye ezahlukene zedivayisi, ngaleyo ndlela isekele ukuxhumana kwazo.

Amasosha ahlala exhumanisa kahle phakathi kobuso be-PCB namadivayisi kagesi. Lawa ma-solder enziwe ngensimbi ewenza abe inhlaka eqinile; ngakho-ke, athembekile ekunikezeni ukwesekwa kwemishini ezingxenyeni. Indlela ye-PCB ivame ukufakwa umquba ngezendlalelo eziningi zezinto ezahlukene ezifana ne-silkscreen nezinsimbi ezifakwe i-substrate ukuze zibe yi-PCB.

Ubuchwepheshe obusha obuhamba phambili namuhla busho ukuthi akukho divayisi kagesi engasebenza ngaphandle kwe-PCB. Ngakolunye uhlangothi, i-PCB ithembele kakhulu kuthusi kunezinye izingxenye. Lokhu kungenxa yokuthi ithusi lisiza ekudaleni iminonjana ehlanganisa zonke izingxenye ku-PCB ukuvumela ukugeleza kweshaja ngaphakathi kwedivayisi. Iminonjana ingachazwa njengemithambo yegazi emathanjeni e-PCB. Ngakho-ke i-PCB ayikwazi ukusebenza lapho iminonjana ingekho. Lapho i-PCB yehluleka ukusebenza, idivayisi kagesi izolahlekelwa umqondo wayo, okwenza ingasebenzi. Ngakho-ke, ithusi liyingxenye eyinhloko yokuqhuba kwe-PCB. I-foil yethusi ku-PCB iqinisekisa ukugeleza okuqhubekayo kwezimpawu ngaphandle kokuphazamiseka.

Izinto zethusi zihlala zaziwa ngokuba nomthamo ophezulu wokuhambisa amandla kunezinye izinto ngenxa yama-electron akhululekile akhona egobolondweni lazo. Ama-electron akhululekile ukuhamba ngaphandle kokumelana nanoma yiliphi i-athomu elenza ithusi likwazi ukuthwala amashaja kagesi ahambayo kahle ngaphandle kokulahlekelwa noma ukuphazamiseka kwezibonakaliso. Ithusi, elenza i-electrolyte engalungile ephelele, lihlala lisetshenziswa kuma-PCB njengesendlalelo sokuqala. Ngenxa yokuthi ithusi alithinteki kakhulu yi-oxygen engaphezulu, lingasetshenziswa yizinhlobo eziningana ze-substrates, izendlalelo zokufaka umswakama, kanye nezinsimbi. Uma lisetshenziswa nalezi zisendlalelo, lakha amaphethini ahlukene kusekethe, ikakhulukazi ngemva kokuqopha. Lokhu kuhlale kwenzeka ngenxa yamandla ethusi okwenza isibopho esiphelele nezendlalelo zokufaka umswakama ezisetshenziswa ukwenza i-PCB.

Ngokuvamile kunezendlalelo eziyisithupha ze-PCB ezenziwe, lapho kunezendlalelo ezine kuzo kwi-PCB. Ezinye izendlalelo ezimbili zivame ukungezwa kuphaneli yangaphakathi. Ngenxa yalesi sizathu, izendlalelo ezimbili zingezokusetshenziswa kwangaphakathi, kukhona nezimbili zokusetshenziswa kwangaphandle, futhi ekugcineni, ezimbili ezisele kweziyisithupha zizonke zingezokuthuthukisa amaphaneli ngaphakathi kwe-PCB.

Isiphetho

Ifoyili yethusiiyisici esibalulekile se-PCB evumela ukugeleza kwamacala kagesi ngaphandle kokuphazamiseka. Inomoya ophakeme futhi yakha kahle isibopho esiqinile ngezinto ezahlukene zokuvikela ezisetshenziswa ebhodini lesifunda le-PCB. Ngenxa yalesi sizathu, i-PCB ithembele ku-foil yethusi ukuze isebenze njengoba yenza ukuxhumana kohlaka lwe-PCB kuphumelele.
