1. Siyini isixhumi se-PCB

A isixhumi sebhodi lesifunda esiphrintiwe, ebizwa nangokuthi isixhumi se-PCB, iwuhlobo lwesixhumi se-elekthronikhi, esisetshenziswa ngokukhethekile ukuxhuma nokulungisa amadivaysi oxhumano lwebhodi lesifunda ephrintiwe, ngokuvamile kusetshenziswa uhlobo lokucindezelwa kwephini, olunamandla okuqinisa ikhebula le-FPC.

Ipulaki (faka) kanye nesokhethi (isihlalo) yizingxenye ezimbili, ngepulaki nesokhethi phakathi kwepulaki ukuze kutholakale ukuxhumana kukagesi noma ukunqanyulwa.Isetshenziswa kakhulu kumishini kagesi, okokuxhumana, ugesi wezimoto, okokusebenza kokulawula izimboni, okokwelashwa, neminye imikhakha.

2. Yiziphi izindima zokusebenza?

1)Ukuxhunywa kukagesi: Amapulagi namasokhethi ngepulaki nesokhethi ukuze kuzuzwe uxhumano lukagesi noma ukunqanyulwa, ukuze kuzuzwe ukudluliswa kwesignali nokudluliswa kwamandla phakathi kwebhodi lesifunda noma phakathi kwentambo nebhodi lesifunda.

2)Ukulungiswa komshini: Ngomsebenzi wokulungisa imishini, ingalungisa ipulaki nesokhethi ngokuqinile ebhodini le-PCB ukuze kuqinisekiswe ukwethembeka nokuzinza koxhumano.

3）Ukonga isikhala: Idizayini ehlangene yokubona ukuxhumeka kwesifunda endaweni elinganiselwe, ngaleyo ndlela konga isikhala sebhodi le-PCB.

(4)Ukusebenza kokuxhuma: Isidingo sokusebenza kahle kokuxhuma, ingaxhunywa njalo futhi ingaxhunywa esimweni sokugcina uxhumano lukagesi oluzinzile ukuze kuhlangatshezwane nezidingo zemishini.

3. Kufanele ngikhethe kanjani i-PCB efanele?

1)Isici sefomu lesixhumi se-PCB

Izigxivizo zomkhiqizo wesixhumi esincane zenza idizayini ye-PCB ibe lula, yehlise izindleko, futhi yehlise ukulahleka kokudlulisela kuyilapho inika amandla uxhumano ukusuka endaweni A ukuya endaweni engu-B. Iphimbo elincane lokuxhumana lenza isixhumi sibe mncane futhi sibe namabhodi esekethe amancane afaneleka kakhulu nezindiza ezingemuva.

2)Izinga lokulahlekelwa kwesignali yezixhumi zebhodi lesifunda

Ngokukhuphuka okukhulu kwezilinganiso zedatha, indlela yokunciphisa ukulahlekelwa kokufaka ukukhathazeka okukhulu kubakhiqizi.Isakhiwo sangaphakathi kanye noxhumana nabo ngaphakathi kwesixhumi badlala indima ebalulekile ekuthuthukiseni ubuqotho besignali nokunciphisa ukulahlekelwa kokufaka.Ngaphezu kwalokho, isixhumi singase futhi sithuthukise isixhumi esibonakalayo sesignali ngokuthuthukisa ukugeleza komoya kanye ne-impedance yesiteshi.

3）I-EMI kanye nokuvikela kwe-ESD kwebhodi lesifunda

Emazingeni aphezulu edatha, ukuvikela ukuphazamiseka kwe-electromagnetic (EMI) kanye nokukhipha i-electrostatic discharge (ESD) sekuye kwabaluleke kakhulu, imvilophu ebonakalayo kanye nezindlela ezikhethekile zokufaka nezindlela zokuqeda kuqinisekisa ukuthi ukuvimbela imiphumela ye-EMI kanye ne-ESD kudlala indima ebalulekile.

4）Ukunqanyulwa kwekhebula kwezixhumi ze-PCB

Leli iphoyinti loshintsho lapho intambo inqanyulwa khona ngesixhumi, okusiza ukwehlisa ukulahleka kwesignali.Isibonelo, ezinye izixhumi ze-PCB ziza neziphethu ezilayishwe ngaphambili ukuvimbela ukukhishwa kwekhebula ngephutha, futhi isixhumi sihlanganisa iyunithi yokunqanyulwa kwentambo nezinsimbi zekhebula kundlu yepulaki.

5）Amandla omshini wezixhumi zebhodi lesifunda

Idizayini yesixhumi eguquguqukayo, eqinile, futhi eqinile isho ukuthi ingakwazi ukumelana nokuqina kwekhebula, ukushisa, ukushaqeka, ukudlidliza namanye amandla angaphandle.Amandla emishini yezixhumi ze-PCB futhi aqinisekisa ukukhwelana okulungile nokuvikeleka kokuxhumana.

4. Umkhuba wokuthuthukiswa kobuchwepheshe besikhathi esizayo

Izixhumi zebhodi lesifunda ziyizingxenye ezibalulekile ezixhuma izingxenye zikagesi nemishini phakathi kwezinto zikagesi.Ngokuduma kanye nokusetshenziswa kwezinga elikhulu kwezisetshenziswa zikagesi ukuduma nokusetshenziswa okukhulu kwemishini kagesi, imboni yesixhumi se-PCB kancane kancane isiphenduke imakethe ethuthukayo nevuthiwe.

Ngokuthuthuka okuqhubekayo kobuhlakani nokuzenzakalelayo, isidingo sezixhumi Zebhodi Lesifunda Ephrintiwe siye sakhula emikhakheni yemishini yasendlini, ugesi wezimoto, ezokuxhumana, izisetshenziswa zezokwelapha, ukuqapha ezokuphepha, njll. Ngaphezu kwalokho, ekukhuthazeni inethiwekhi ye-5G, i ukusetshenziswa kwesidingo semishini yezokuxhumana nakho kukhula kakhulu.Isidingo somhlaba wonke semishini ye-elekthronikhi siyaqhubeka nokukhula, futhi isidingo semakethe yesixhumi se-PCB naso kancane kancane sibonisa ukuthambekela okuhlukahlukene, komuntu siqu.

Ukuncintisana okukhulayo emakethe ye-elekthronikhi, ukuze umklamo webhodi lesifunda kanye nobuchwepheshe bokukhiqiza buqhubekele phambili, ukuze inqubo yokukhiqiza kanye nokuthuthukiswa kwezixazululo zokukhiqiza ezihlakaniphile kudinga ukuthuthukiswa okuqhubekayo ukuze kuhlangatshezwe kangcono nesidingo semakethe esizayo.
