PCB izinto zokusetshenziswa ezimbonini ikakhulu zifaka ingilazi yefayibha yensimbi, ucwecwe lwethusi, ibhodi egqoke ithusi, i-epoxy resin, uyinki, uginindela wokhuni, njll. Ibhodi eligqoke ithusi lenziwe ngocwecwe lwethusi, i-epoxy resin, ingilazi yefayibha nentambo nezinye izinto zokusetshenziswa. Ezindlekweni zokusebenza kwe-PCB, izindleko zempahla eluhlaza zisetshenziselwa ingxenye enkulu, cishe i-60-70%.

Uchungechunge lwemboni ye-PCB kusuka phezulu kuye phansi “izinto zokusetshenziswa – i-substrate – uhlelo lwe-PCB”. Izinto ezikhuphukayo zifaka ucwecwe lwethusi, i-resin, ingilazi yefayibha yengilazi, uginindela wokhuni, uyinki, ibhola lethusi, njll. Ucwecwe lwethusi, i-resin nengubo yengilazi yefayibha yizinto ezintathu eziyinhloko zokusetshenziswa. Okuphakathi kwesisekelo okuphakathi ikakhulu kubhekise kupuleti egqoke ithusi, ingahlukaniswa ipuleti egqokiwe yethusi kanye nepuleti egqoke ithusi eguqukayo, okuyipuleti egqokiwe yethusi ehlukanisiwe ingahlukaniswa yaba yipuleti egqoke ithusi egqoke iphepha, impahla ehlanganisiwe esekwe ipuleti egqoke ithusi nengilazi yefayibha ipuleti egqoke ithusi ngokuya ngento eqinisiwe; Umfula osebenza phansi ukusetshenziswa kwazo zonke izinhlobo ze-PCB, futhi uchungechunge lwezimboni ukusuka phezulu kuye phansi umkhakha wezinga lokuhlushwa lincipha ngokulandelana.

Umdwebo wesakhiwo se-PCB umkhakha weketanga

Ngenhla komfula: Ucwecwe lwethusi luyinto eluhlaza ebaluleke kakhulu yokwenziwa kwamapuleti agqokiwe ethusi, okubalwa cishe ngama-30% (ipuleti elijiyile) no-50% (ipuleti elincanyana) yezindleko zamapuleti agqokiwe ethusi.Intengo yensimbi yethusi incike ekushintsheni kwentengo yethusi, okuthinteka kakhulu ngentengo yethusi yamazwe omhlaba. Ucwecwe lwethusi luyinto ye-cathodic electrolysis, ecindezelwe kusendlalelo sebhodi lesifunda, njengezinto eziqhutshwa ku-PCB, idlala indima ekwenzeni nasekupholiseni. Indwangu ye-fiberglass ingenye yezinto zokusetshenziswa zamapaneli agqokwe ngethusi. Ilukiwe ngentambo yengilazi yefayibha futhi ibalelwa kuma-40% (ipuleti elijiyile) kanye nama-25% (ipuleti elincanyana) yezindleko zamaphaneli agqokiwe ngethusi. Indwangu ye-fiberglass ekwakhiweni kwe-PCB njengoba impahla yokuqinisa idlala indima ekwandiseni amandla nokufakwa, kuzo zonke izinhlobo zendwangu ye-fiberglass, i-resin yokwenziwa ekukhiqizeni i-PCB isetshenziswa kakhulu njengesibopho sokunamathisela indwangu ye-fiberglass ndawonye.

Ukuhlushwa komkhakha we-Copper foil kuphezulu, imboni ihola amandla okuxoxisana. Ucwecwe lwethusi lwe-electrolytic ikakhulukazi lokusetshenziswa kokukhiqizwa kwe-PCB, inqubo yezobuchwepheshe ye-elektroniki yethusi ye-elektroni, ukucubungula okuqinile, izithiyo zezimali nezobuchwepheshe, kuhlanganiswe idigri lokuhlushwa kwemboni kuphakeme, ukukhiqizwa komhlaba wonke kwethusi lethusi abakhiqizi abayishumi abaphezulu bahlala ku-73%, we amandla okuxoxisana embonini yocingo lwethusi aqinile, izinto ezisetshenziswayo ezikhuphukayo zamanani ethusi ukuhamba phansi. Intengo yocingo lwethusi ithinta intengo yensimbi egqokiwe yethusi, bese ibangela ukuguqulwa kwentengo yebhodi lesifunda phansi.

Ingilazi yefibre yenkomba yenkanyezi ekhuphuka mkhuba

Ephakathi nomkhakha: Ipuleti elimbozwe ngethusi lingumongo oyisisekelo wokukhiqizwa kwe-PCB. Indwangu yethusi ibhabhadise izinto eziqinisiwe nge-resin ephilayo, uhlangothi olulodwa noma izinhlangothi ezimbili zimbozwe ucwecwe lwethusi, ngokucindezela okushisayo futhi kube uhlobo lwento yepuleti, ye (PCB), yokuqhuba, yokwambathisa, ukuxhasa imisebenzi emithathu emikhulu, ibhodi elikhethekile elaminishwe uhlobo olukhethekile ekukhiqizeni i-PCB, okugqokiwe ithusi okungu-20% ~ 40% wezindleko zomkhiqizo wonke we-PCB, kuzo zonke izindleko zezinto ze-PCB ezibalwa kakhulu, I-fiberglass indwangu substrate uhlobo oluvame kakhulu lwepuleti elimbozwe ngethusi, elenziwe ngendwangu ye-fiberglass njengezinto zokuqinisa kanye ne-epoxy resin njenge-binder.

Ezansi nomkhakha wemboni: izinga lokukhula kwezicelo zendabuko lincipha, kuyilapho izicelo ezivelayo zizoba amaphuzu okukhula. Izinga lokukhula KWEZICELO ZENDabuko ku-PCB esezansi kwehla kancane, ngenkathi kufakwa izicelo ezivelayo, ngokuthuthuka okuqhubekayo kwe-elekthronikhi yezimoto, ukwakhiwa okukhulu kwe-4G kanye nokuthuthukiswa kwesikhathi esizayo kwe5G kuqhuba ukwakhiwa kwemishini yesiteshi sezokuxhumana, i-PCB yemoto kanye ne-PCB yokuxhumana izoba amaphuzu amasha wokukhula ngokuzayo.
