Ngokuthuthuka okusheshayo kwemboni yezogesi, ukusetshenziswa kwama-PCB nakho kukhuphuke kakhulu.Kodwa-ke, ukusetshenziswa kwayo ezinhlelweni ezahlukene kusho ukuthi ama-PCB angaphansi kwezimo ezihlukene zemvelo.Lapho i-PCB ichayeke kumswakama noma amakhemikhali anokhahlo, ukusebenza kungase kukhathaze.Ngakho-ke, i-PCB kufanele imbozwe ukuyivikela ezimweni zemvelo.Lokhu kuvikelwa kungafinyelelwa ngokumbozwa ngokusemthethweni noma ngokufaka imbiza noma nge-encapsulation.
Ama-Potting and encapsulation resins ahamba ibanga elide ekuhlinzekeni amazinga aphezulu okuvikela kuma-PCB.Eqinisweni, ukupakishwa kunikeza kokubili izici zikagesi kanye nokuvikelwa komshini.Leli zinga eliphakeme lokuvikela liqinisekiswa inani elikhulu le-resin ezungeza yonke iyunithi.Lokhu kukhulu kakhulu uma kuqhathaniswa nama-conformal coatings.Eqinisweni, ukubumba kanye ne-encapsulation kunikeza isivikelo esingenangqondo.Kodwa-ke, ama-resin okubumba kanye ne-encapsulating adinga ukuhlolwa ezindaweni eziningi ukuze kunqunywe ukucaciswa kwawo kanye nokufaneleka kwawo ukusetshenziswa.Lokhu kuhlola kuvame ukubandakanya ukuziveza ezimweni zomoya ezilawulwayo phakathi nenkathi ethile.Ubukhulu, isisindo kanye nokubukeka kwe-resin kungabonakala ngaphambi nangemva kokuhlolwa ukuze kuhlolwe noma yiziphi izinguquko.
Ngokungeziwe kuma-potting kanye nama-encapsulation resins, ukunamathela okuhlelekile kungasetshenziswa futhi ukuvikela ama-PCB.Lokhu kwenziwa ngokusetshenziswa njenge-membrane.Njengoba ifilimu ithatha iphrofayili yebhodi, ayibangeli izinguquko zobukhulu noma yengeze isisindo esibalulekile.Eqinisweni, lokhu kunenzuzo kuma-conformal coatings ngoba kwenza kube lula ukwenza amadivaysi aphatheke.Kodwa-ke, ukuhlolwa kuyadingeka ukuze kuhlolwe izakhiwo zikagesi nezemishini zamafilimu ezindaweni ezisebenzayo.Amafilimu adinga ukuhlolwa ngaphansi kwezimo ezifana nomswakama, izinga lokushisa, njll. ukuze kutholwe ukufaneleka kwefilimu kulesi simo somoya.
I-conformal coating kanye ne-encapsulation kanye ne-potting kuyatholakala ngamasayizi ahlukene ukuze akwenze afanelekele izinhlelo zokusebenza ezithile.Ezimweni eziningi ezijwayelekile, ukunamathela okuvumelanayo kusebenza kahle kanye nokufaka i-potting kanye ne-resin encapsulation.Kodwa-ke, uma izimo zinzima, ukukhetha kokugqoka kuzohluka.Isibonelo, i-acrylic coatings isebenza kahle ngokuchayeka njalo ekukhanyeni kwe-UV.Kodwa-ke, i-acrylic coatings ingase ingasebenzi kahle ezimweni ezinamazinga aphezulu omswakama.Ngaphansi kwalezi zimo, opende abangewona abe-VOC bangenza kangcono.
Ukusebenza okuphezulu kwedivayisi kutholakala ngokusetshenziswa kwe-potting nama-encapsulation resin lapho ukucindezeleka okukhulu komshini noma izimo zemvelo ezinzima zingase zibe khona.Ama-silicone noma ama-polyurethane resins aziwa ngokuhlinzeka ngezinga elikhulu lokuguquguquka.Eqinisweni, lapho amazinga okushisa ephansi kakhulu, kukhethwa ama-polyurethane resins.Futhi zilungele amadivayisi acwiliswe emanzini.Endabeni yokuchayeka kumakhemikhali, ama-epoxy resins ayakhethwa.
Ngakho-ke, kusobala ukuthi ukukhethwa kokugqoka kuhlobene kakhulu nendawo ebonakalayo lapho imishini isebenza khona.Izilinganiso zokumboza ezivumelanayo zamapharamitha njengokulula kanye nesivinini sokucutshungulwa, ukugawulwa kwezimbiza kanye nama-resin encapsulating kuyathandwa nakuba kusesimweni sezulu esibi.Izembatho ezivumelanayo nazo ziyakhethwa lapho kudingeka khona ukwenziwa kancane nokuphatheka kwedivayisi.Ngenxa yokuthi zombili zinikeza izinzuzo ezicacile, ukuhlolwa okuphelele kwezidingo zakho eziyingqayizivele kubalulekile ngaphambi kokunquma nge-coating.
