Ngokuthuthuka okusheshayo komkhakha we-elekthronikhi, PCB ukuhlanganisa izintambo kuya ngokuya kucaca. Abakhiqizi abaningi be-PCB basebenzisa ifilimu eyomile ukuqedela ukudluliswa kwemifanekiso, futhi ukusetshenziswa kwefilimu eyomile kuya ngokuya kwanda. Kodwa-ke, ngenkathi kwenziwa insizakalo yokuthengisa ngemuva, ngisahlangana namakhasimende amaningi enza amaphutha amaningi lapho esebenzisa ifilimu eyomile.

Okokuqala, kuvela izimbobo zemaski ezomile

Amaklayenti amaningi acabanga ukuthi, ngemuva komgodi ophukile, kufanele akhuphule izinga lokushisa kwefilimu nengcindezi, futhi athuthukise amandla awo okubopha, empeleni lolu hlobo lokubuka alulungile, ngoba ngemuva kokushisa okuphezulu nokucindezela, ungqimba olumelana nokugqwala kwe-solvent volatilization ngokweqile, yenza ifilimu eyomile sinomzimba omncane futhi sengozini yokungena emgodini lapho sikhula, sihlala sifuna ukugcina ukuqina kwefilimu eyomile, ngakho-ke, ngemuva komgodi ophukile, singakwenza kusuka kula maphuzu alandelayo ukuze sithuthukise:

1, ukunciphisa izinga lokushisa kwefilimu kanye nengcindezi

2, ngcono imishini drape ngaphambili

3, ngcono ukuvezwa kwamandla

4, ukunciphisa ukuthuthukiswa kwengcindezi

5, isikhathi sokupaka ngemuva kwefilimu asikwazi ukuba side kakhulu, ukuze singaholi engxenyeni esekhoneni lefilimu ewuketshezi ngaphansi kwesenzo sokucindezela ukusabalalisa

I-6, ungayeluli ifilimu eyomile iqine kakhulu kwinqubo yefilimu

Okubili, ukoma kwefilimu owomile kwenzeka ukungena

Isizathu sokufakwa kokungena ukuthi ifilimu eyomile nefilayi elimbozwe ngethusi akuhlanganisiwe ngokuqinile, okujulisa isixazululo sokufaka futhi kuqinise ingxenye “yesigaba esibi” sengubo. Ukufakwa kokungena kwenzeka kubakhiqizi abaningi be-PCB ngenxa yezizathu ezilandelayo:

1. Amandla wokuvezwa okuphezulu noma aphansi

Ngaphansi kokukhanya kwe-ultraviolet, i-photoinitiator emunca amandla wokukhanya ibola ibe yi-radical yamahhala ukuqala i-monomer ekuphenduleni i-photopolymerization, yakha i-molecule yomzimba engancibiliki kwisisombululo se-alkali. Lapho ukuvezwa kunganele, ngenxa yokungaphelele kwe-polymerization, enqubeni ekhulayo, ukuvuvukala kwefilimu kuba buthambile, okuholela emigqeni engacacile futhi ungqimba lwefilimu luyawa, okuholela ekuhlanganisweni okungalungile kwefilimu nethusi; Uma ukuvezwa kukweqile, kuzodala ubunzima ekukhuleni, futhi kuzokhiqiza nokugoqa kanye nokuhlubula inqubo yokufaka, ukwakha ukufakwa kokungena. Ngakho-ke kubalulekile ukulawula amandla wokuchayeka.

2. Izinga lokushisa lefilimu liphezulu noma liphansi

Uma izinga lokushisa lefilimu liphansi kakhulu, ngenxa yefilimu yokumelana nokugqwala ayikwazi ukuthola ukuthamba okwanele nokugeleza okufanele, okuholele ekubambeleleni okubi phakathi kwefilimu eyomile nethusi egqoke indawo yokuhlobisa; Uma izinga lokushisa liphezulu kakhulu ngenxa yokwehla ngokushesha kwe-solvent nezinye izinto eziguquguqukayo ku-resist and bubbles, futhi ifilimu elomile liba brittle, lenze ikhasi elijiyayo lapho lishayisa ugesi ngamandla, kuholele ekungeneni kokungena.

3. Ingcindezi yefilimu iphezulu noma iphansi

Lapho ingcindezi yefilimu iphansi kakhulu, ingadala ukungalingani kwefilimu noma igebe phakathi kwefilimu eyomile nepuleti lethusi futhi ingahlangabezani nezidingo zamandla okubopha; Uma ingcindezi yefilimu iphezulu kakhulu, izingxenye ezixazululayo nezingazinzile zesendlalelo se-anticorrosive ziyaguquguquka kakhulu, okuholela kufilimu eyomile, ezosonteka ngemuva kokushaywa yi-electroplating.
