Eminyakeni yamuva, cishe umuntu oyedwa unemishini ye-elekthronikhi engaphezu kweyodwa, futhi imboni ye-electronics ithuthuke ngokushesha, okuye kwakhuthaza ukukhuphuka okusheshayo kwemboni yebhodi lesifunda le-PCB. Eminyakeni yakamuva, abantu banezidingo eziphakeme neziphakeme zokusebenza kwemikhiqizo ye-elekthronikhi, okuphinde kwaholela ezidingweni eziphakeme neziphakeme zekhwalithi yamabhodi esekethe. Indlela yokuhlukanisa ikhwalithi yamabhodi wesifunda se-PCB isiphenduke isihloko sokukhathazeka okwandayo.
Indlela yokuqala ukuhlola okubukwayo, okuyinhloko ukuhlola ukubukeka kwebhodi lesifunda. Into eyisisekelo kakhulu yokuhlola ukubukeka ukuhlola ukuthi ukushuba nobukhulu bebhodi kuyahlangabezana yini nobukhulu kanye nemininingwane oyidingayo. Uma kungenjalo, udinga ukuphinda ukwenze. Ngaphezu kwalokho, ngokuncintisana okunamandla emakethe ye-PCB, izindleko ezihlukahlukene ziyaqhubeka nokukhuphuka. Ukuze kuncishiswe izindleko, abanye abakhiqizi bayaqhubeka nokunciphisa izindleko zezinto ezibonakalayo kanye nezindleko zokukhiqiza. Amashidi e-HB, cem-1, kanye ne-cem-3 avamile angasebenzi kahle futhi kulula ukuwohloka, futhi angasetshenziswa kuphela ekukhiqizeni ohlangothini olulodwa, kuyilapho amaphaneli e-fr-4 fiberglass engcono kakhulu emandleni nasekusebenzeni, futhi avame ukusetshenziswa. kumaphaneli anezinhlangothi ezimbili namacala amaningi. Ukukhiqizwa kwama-laminates. Amabhodi enziwe ngamabhodi aphansi ngokuvamile anemifantu nemihuzuko, okuthinta kakhulu ukusebenza kwamabhodi. Lapha futhi lapho udinga ukugxila ekuhloleni okubonakalayo. Ngaphezu kwalokho, noma ngabe inki ye-solder imaski iyisicaba, noma ngabe ikhona ithusi eliveziwe; noma ngabe isikrini sikasilika sohlamvu sisusiwe, noma ngabe iphedi ivuliwe noma cha nayo idinga ukunakwa.
Ngemuva kokuthi indlela yesibili idinga ukusetshenziswa, iphuma ngempendulo yokusebenza. Okokuqala, ingasetshenziswa ngokujwayelekile ngemva kokufakwa kwezingxenye. Lokhu kudinga ukuthi ibhodi lesifunda alinayo isifunda esifushane noma isifunda esivulekile. Imboni inenqubo yokuhlola kagesi ngesikhathi sokukhiqiza ukuze ibone ukuthi ibhodi linomjikelezo ovulekile noma omfushane. Kodwa-ke, abanye abakhiqizi bebhodi bayasindisa Izindleko azikho ngaphansi kokuhlolwa kukagesi (Ukufakazela ku-Jiezi, ukuhlolwa kukagesi okungu-100% kuthenjisiwe), ngakho leli phuzu kufanele licaciswe lapho kuqinisekiswa ibhodi lesifunda. Bese uhlola ibhodi lesifunda ukuze ukhiqize ukushisa ngesikhathi sokusetshenziswa, okuhlobene nokuthi ububanzi bomugqa/ibanga lomugqa wesekethe ebhodini linengqondo. Lapho u-soldering i-patch, kuyadingeka ukuhlola ukuthi i-pad iwele ngaphansi kwezimo zokushisa eziphakeme, okwenza kube nzima ukudayiswa. Ngaphezu kwalokho, ukumelana nokushisa okuphezulu kwebhodi nakho kubaluleke kakhulu. Inkomba ebalulekile yebhodi inani le-TG. Lapho enza ipuleti, unjiniyela udinga ukuyala ifekthri yebhodi ukuthi isebenzise ibhodi elihambisanayo ngokuvumelana nezimo ezihlukahlukene zokusetshenziswa. Okokugcina, isikhathi esivamile sokusetshenziswa kwebhodi futhi siyinkomba ebalulekile yokukala ikhwalithi yebhodi.
Uma sithenga amabhodi esekethe, asikwazi ukuqala ngentengo yodwa. Kufanele futhi sicabangele izinga lamabhodi esekethe futhi sicabangele zonke izici ngaphambi kokuba sithenge amabhodi esekethe angabizi kakhulu.
