Umswakama uyisici esivame kakhulu nesilimazayo kumabhodi esekethe e-PCB.Umswakama owedlulele uzonciphisa kakhulu ukumelana nokufakwa phakathi kwamakhondatha, kusheshise ukubola ngesivinini esikhulu, kunciphise inani le-Q, futhi kugqwelise amakhondaktha.Sivame ukubona i-patina engxenyeni yensimbi yamabhodi esekethe e-PCB, ebangelwa ukusabela kwamakhemikhali phakathi kwethusi lensimbi nomhwamuko wamanzi nomoya-mpilo ongambozwanga ngopende ohambisanayo.
Futhi amakhulukhulu okungcola atholakala ngokungahleliwe emabhodini esekethe aphrintiwe angalimaza ngendlela efanayo.Zingabangela imiphumela efanayo nokuhlasela komswakama—ukubola kwama-electron, ukugqwala kwamakhondatha, ngisho namasekhethi amafushane angalungiseki.Ukungcola okuvame kakhulu okutholakala ezinhlelweni zikagesi kungase kube amakhemikhali asele ohlelweni lokukhiqiza.Izibonelo zalokhu kungcola zihlanganisa ama-fluxes, ama-solvent release agents, izinhlayiya zensimbi noyinki wokumaka.Kukhona futhi namaqembu amakhulu okungcola okubangelwa ukuphatha kwabantu budedengu, njengamafutha omzimba womuntu, izigxivizo zeminwe, izimonyo nezinsalela zokudla.Kukhona nezinto eziningi ezingcolisayo endaweni yokusebenza, njengesifutho sikasawoti, isihlabathi, uphethiloli, i-asidi, enye imfucumfucu egqwalayo kanye nesikhunta.
Ukumboza upende ongekho emthethweni emabhodini esekethe aphrintiwe kanye nezingxenye kunganciphisa noma kuqede ukuwohloka kokusebenza kwe-elekthronikhi lapho kungase kuthinteke izici ezimbi endaweni yokusebenza.Uma lolu hlobo lokumboza lungagcina umphumela walo isikhathi esanelisayo, njengesikhathi eside kunempilo yesevisi yomkhiqizo, lungathathwa njengolufinyelele inhloso yalo yokumboza.
Umshini wokunamathela oqinile wokulwa nopende
Ngisho noma ungqimba olunamathelayo luncane kakhulu, lungakwazi ukumelana nokudlidliza nokushwibeka kwemishini, ukushaqeka okushisayo, nokusebenza emazingeni okushisa aphakeme ngokwezinga elithile.Yiqiniso, akulungile ukucabanga ukuthi amafilimu angasetshenziswa ukunikeza amandla omshini noma ukufakwa okwanele ezingxenyeni zomuntu ngamunye ezifakwe ebhodini lesifunda eliphrintiwe.Izingxenye kufanele zifakwe ngomshini futhi kufanele zibe nama-cauls azo afanelekile, ngakho-ke kunomshuwalense ophindwe kabili ngokumelene nezingozi.
1. I-solvent-containing acrylic resin conformal anti-paint (okwamanje umkhiqizo osetshenziswa kakhulu futhi odumile emakethe).
Izici: Inezici zokomisa phezulu, isikhathi sokuphulukisa ngokushesha, izakhiwo ezinhle ezinobufakazi obuthathu, intengo eshibhile, umbala osobala, ukuthungwa okuguquguqukayo nokulungisa kalula.
2. Upende lwe-acrylic resin oluhambisanayo olungancibilikisiwe.
Izici: Ukwelapha kwe-UV, kungomiswa emizuzwaneni embalwa kuya kwengaphezu kwemizuzwana eyishumi, umbala usobala, ukuthungwa kunzima, futhi ukumelana nokugqwala kwamakhemikhali nokugqoka nakho kuhle kakhulu.
3. Polyurethane conformal upende.
Izici: ukuthungwa kwe-brittle kanye nokumelana okuhle kwe-solvent.Ngaphezu kokusebenza kwayo okuhle kakhulu kokuvikela umswakama, iphinde ibe nokusebenza okuzinzile ezindaweni ezisezingeni eliphansi lokushisa.
4. I-Silicone ngopende ohambisanayo.
Izici: Izinto ezithambile zokunwebeka, ukukhululeka okuhle kwengcindezi, ukumelana nokushisa okuphezulu kwama-degree angama-200, kulula ukukulungisa.
Ukwengeza, ngokombono wentengo nokusebenza, kukhona futhi isenzakalo se-crossover phakathi kwezinhlobo ezingenhla ze-conformal coatings, njenge-silicone-modified conformal coatings.
