Iibhodi zesekethe eziguquguqukayo, ezaziwa ngokuba ziisekethe eziguquguqukayo okanye iibhodi zesekethe eziprintiweyo (PCBs), ziyinxalenye ebalulekileyo kwizixhobo ezininzi zombane.Ngokungafaniyo neesekethe eziqinileyo, iisekethe eziguquguqukayo zinokugoba, ukujija kunye nokugoba, zizenze zilungele usetyenziso olufuna uyilo oluntsonkothileyo okanye imiqobo yendawo.Nangona kunjalo, njengayo nayiphi na inkqubo yokuvelisa, eminye imingeni inokuvela ngexesha lokuveliswa kweebhodi zeesekethe eziguquguqukayo.
Omnye wemiba ephambili ejongene nayo ngexesha lokwenziwa kwemveliso kubunzima bokuyila iisekethe eziguquguqukayo.Ngenxa yokuguquguquka kwazo, ezi bhodi zihlala zifuna iiplani eziyinkimbinkimbi kunye nezikhethekileyo.Ukuyila isiphaluka esinokugoba ngaphandle kwempembelelo embi ekudibaneni kombane okanye amacandelo ngumsebenzi onzima.Ukongezelela, ukuqinisekisa ukuba i-flex circuit iyakwazi ukuhlangabezana nemilinganiselo yokusebenza yombane efunekayo yongeza umaleko owongezelelweyo wobunzima.
Omnye umqobo ojongene nawo ngexesha lokuveliswa kwebhodi yesekethe eguquguqukayo kukukhethwa kwezinto eziphathekayo.Iisekethe eziguquguqukayo zihlala zinemigangatho emininzi yefilimu ye-polyimide, imikhondo yobhedu, kunye nezixhobo zokuncamathelisa.Ezi zixhobo kufuneka zikhethwe ngokucophelela ukuqinisekisa ukuhambelana nokuthembeka.Ukukhetha izinto ezingalunganga kunokubangela ukuguquguquka okubi, ubomi obufutshane, okanye ukusilela kwebhodi yesekethe.
Ukongeza, ukugcina iphethini yesekethe ukuchaneka ngexeshainkqubo yokuvelisaikwalucelomngeni.Ngenxa yokuguquguquka kwezi bhodi, ukulungelelaniswa okuchanekileyo kubalulekile.Ngexesha leenkqubo ezifana ne-etching, i-lamination okanye i-drilling, ukungahambi kakuhle kunokwenzeka, kubangele ukungahambi kakuhle okanye iisekethe ezimfutshane.Abavelisi kufuneka baqinisekise ukuba kukho amanyathelo angqongqo okulawula umgangatho ukuze kuncitshiswe imiba yokungalungelelanisi kakuhle.
Omnye umba oqhelekileyo ojongene nawo ngexesha lokuveliswa kwebhodi yesekethe eguquguqukayo kukuthembeka kwe-adhesive ebamba iileya kunye.I-adhesive idinga ukubonelela ngeqhina eliqinileyo kunye nexesha elide phakathi kweengqimba ngaphandle kokunciphisa ukuguquguquka kwesekethe.Ngokuhamba kwexesha, utshintsho kwiqondo lokushisa, umswakama, okanye uxinzelelo lomatshini lunokuchaphazela ingqibelelo ye-adhesive, ebangela ukuba ibhodi idilize okanye ingaphumeleli.
Iisekethe eziguquguqukayo nazo zibonelela ngemingeni ngexesha lovavanyo kunye nokuhlolwa.Ngokungafaniyo neebhodi zeesekethe eziqinileyo, iisekethe eziguquguqukayo azikwazi ukunyanzeliswa ngokulula okanye zikhuselwe ngexesha lovavanyo.Ukuqinisekisa uvavanyo oluchanekileyo noluthembekileyo, ukhathalelo olongezelelweyo lufunekayo, olunokutya ixesha elide kwaye lunzima.Ukongeza, ukuphawula iimpazamo okanye iziphene kwiisekethe eziguquguqukayo kunokuba ngumngeni ngakumbi ngenxa yoyilo oluntsonkothileyo kunye nolwakhiwo olunemigangatho emininzi.
Ukudibanisa amacandelo kwiibhodi zeesekethe eziguquguqukayo nako kudala iingxaki.Izinto ezincinci zokuxhoma umphezulu ezinesandi esicolekileyo zifuna ukubekwa okuchanekileyo kwiisubstrates eziguquguqukayo.Ukuguquguquka kweebhodi zeesekethe kwenza kube nzima ukugcina ukuchaneka okufunekayo ngexesha lokubekwa kwecandelo, ukwandisa umngcipheko wecandelo le-tilt okanye ukungahambi kakuhle.
Ekugqibeleni, imveliso yokuvelisa iibhodi zeesekethe eziguquguqukayo ingaba ngaphantsi xa kuthelekiswa neebhodi eziqinileyo.Iinkqubo ezinzima ezibandakanyekayo, ezifana ne-multi-layer lamination kunye ne-etching, zidala amandla aphezulu okukhubazeka.Isivuno sinokuchatshazelwa yimiba efana neepropati eziphathekayo, izixhobo zokuvelisa, okanye inqanaba lesakhono somsebenzisi.Abavelisi kufuneka batyale imali kwitekhnoloji ephezulu kunye nokuphuculwa kwenkqubo eqhubekayo ukunyusa imveliso kunye nokunciphisa iindleko zemveliso.
Lilonke, inkqubo yokwenziwa kwebhodi yesekethe eguquguqukayo ayikho ngaphandle kwemingeni yayo.Imiba emininzi inokuvela, ukusuka kwiimfuno zoyilo oluntsonkothileyo ukuya ekukhetheni izinto eziphathekayo, ukusuka ekuchanekeni kolungelelwaniso ukuya ekuthembekeni kwebhondi, ukusuka kubunzima bokuvavanya ukuya ekudityanisweni kwecandelo, kunye nezivuno ezisezantsi zokuvelisa.Ukoyisa le miqobo kufuna ulwazi olunzulu, ucwangciso olucokisekileyo, kunye nokuphuculwa okuqhubekayo kobugcisa bokuvelisa.Ngokujongana ngempumelelo nale mingeni, abavelisi banokuvelisa umgangatho ophezulu kunye neebhodi zeesekethe eziguquguqukayo ezithembekileyo kwiintlobo ezahlukeneyo zezicelo kwishishini le-elektroniki.
