1. Ipuleti le-Copper ngokwalo elibangelwa ukunwetshwa nokufinyela okushisayo;

2. Uma igrafu idluliswa, izinto zefilimu emnyama nefilimu ebomvu i-celluloid, eyanda futhi iyancipha ngaphansi kwethonya lomswakama kanye nezinga lokushisa; Izimo zembobo phakathi kwefilimu eveziwe yesithombe ne-PCB ngemva kokunwetshwa nokufinyela azifani, futhi izindawo zokuma kwembobo azifani. Ekugcineni, ngemva kokulethwa komkhiqizo, kukhona ukubekezelelana ne-jack yengxenye negobolondo lomkhiqizo, ngakho-ke lapho wenza ibhodi yesifunda ephrintiwe, ifilimu akufanele ibe nkulu kakhulu, futhi izinga lokushisa nomswakama kufanele kulawulwe ngokuqinile.

3. Ukunwetshwa nokufinyezwa kwesikrini, imiphumela ebangelwa ukunwetshwa nokufinyela kuyafana nokungu-2.

Ungayithuthukisa kanjani i-PCB shrinkage

Ngomqondo oqinile, ukucindezeleka kwangaphakathi komqulu ngamunye wezinto ezibonakalayo kuhlukile, futhi ukulawulwa kwenqubo yeqoqo ngalinye lamapuleti okukhiqiza ngeke kufane ncamashi. Ngakho-ke, ukubanjwa kwe-coefficient yokunwetshwa nokufinyezwa kwezinto kusekelwe enanini elikhulu lokuhlolwa, futhi ukulawulwa kwenqubo nokuhlaziywa kwezibalo zedatha kubaluleke kakhulu. Ekusebenzeni okungokoqobo, ukunwetshwa nokufinyezwa kwepuleti eliguquguqukayo kuhlukaniswe izigaba:

Okokuqala, kusukela ekuvuleni kuya epuletini lokubhaka, lesi sigaba sibangelwa ikakhulukazi izinga lokushisa:

Ukuqinisekisa ukuzinza kokunwetshwa nokufinyela okubangelwa ipuleti lokubhaka, okokuqala, ukuvumelana kokulawulwa kwenqubo, ngaphansi kwesisekelo sezinto ezifanayo, ukushisa kwepuleti ngalinye lokubhaka kanye nokusebenza kokupholisa kufanele kuhambisane, hhayi ngenxa yokuphishekela ukusebenza kahle, kanye nepuleti lokubhaka eliphelile emoyeni ukuze kukhishwe ukushisa. Ngale ndlela kuphela, ukuze kwandiswe ukuqedwa kokucindezeleka kwangaphakathi okubonakalayo okubangelwa ukunwetshwa nokufinyela.

Isigaba sesibili senzeka ohlelweni lokudluliswa kwegrafu. Ukwandiswa nokufinyela kwalesi sigaba kubangelwa ngokuyinhloko ukuguqulwa kokuma kwengcindezi kundaba.

Ukuqinisekisa ukuthi isifunda siyenyuka kanye nokuzinza kwenqubo yokudlulisa, bonke abakwazi ukubhaka ibhodi elihle ukuze lisebenze ipuleti, ngokuqondile ngokusebenzisa umugqa wokuhlanza wamakhemikhali ngaphambi kokwelashwa, ngemva kokuba i-membrane yokucindezela kufanele ivuleke, ubuso bebhodi buvumele ukuma ngaphambi nangemuva. isikhathi sokuchayeka kufanele sanele, ngemuva kokudluliswa komugqa wokugcina, ngenxa yoshintsho lwe-orientation yokucindezeleka, ipuleti eliguquguqukayo lizoletha izinga elihlukile le-crimp nokufinyela, Ngakho-ke, ukulawulwa kwesinxephezelo sefilimu yomugqa kuhlobene nokulawulwa kokunemba okuhlangene okuqinile, futhi ukunqunywa kobubanzi benani lokunwetshwa nokufinyela kwepuleti eguquguqukayo kuyisisekelo sedatha sokukhiqizwa kwepuleti layo eliqinile elisekelayo. .

Ukwandiswa nokufinyela kwesigaba sesithathu kwenzeka ngesikhathi sokucindezela kwepuleti eliqinile eliguquguqukayo, elinqunywa imingcele ecindezelayo eyinhloko kanye nezakhiwo ezibonakalayo.

Izici ezithinta ukunwetshwa nokufinyela kulesi sigaba zifaka izinga lokushisa lokucindezela, ukumiswa kwemingcele yokucindezela kanye nezinga lensalela yethusi nogqinsi lwe-core plate. Ngokuvamile, isilinganiso sethusi esisele sincane, inani lokunwetshwa nokufinyela liba likhulu. Lapho ibhodi eliwumongo liba mncane, likhulu inani lokunwetshwa nokufinyezwa. Kodwa-ke, kusukela kokukhulu kuya kokuncane, inqubo yoshintsho kancane kancane, ngakho-ke, isinxephezelo sefilimu sibaluleke kakhulu. Ngaphezu kwalokho, ngenxa yemvelo ehlukene yezinto ezibonakalayo zepuleti eliguquguqukayo kanye nepuleti eliqinile, isinxephezelo saso siyisici esengeziwe okufanele icatshangelwe.
