Izakhiwo zokucubungula zamabhodi wesifunda aguquguqukayo zithinta ukusebenza kwazo kanye nezicelo

Kulokhu okuthunyelwe kwebhulogi, sizongena ekubalulekeni kokuguquguquka kwebhodi lesifunda futhi sihlole ukuthi kuthinta kanjani ukusebenza kwayo nezinhlelo zokusebenza.

Amabhodi esekethe aguquguqukayo, aziwa nangokuthi ama-PCB aguqukayo, aguqule umkhakha wezogesi ngezakhiwo zawo ezihlukile namandla amakhulu.Lawa mabhodi anikeza ukuguquguquka, ukwethembeka, kanye nokuguquguquka, okuwenza alungele izinhlelo zokusebenza ezihlukahlukene.Phakathi kwezici eziningi ezinquma ukusebenza kwebhodi lesifunda eliguquguqukayo, isici esiyinhloko ukucutshungulwa kwalo.

Ukucutshungulwa kubhekisela ekululameni lapho ibhodi lesekethe eliguquguqukayo lingenziwa khona, lihlanganiswe, futhi lihlanganiswe ezintweni zikagesi.Ihlanganisa amasu okukhiqiza ahlukahlukene, izinto zokwakha kanye nokucatshangelwa kwedizayini okuthinta ngqo ikhwalithi nokusebenza komkhiqizo wokugcina.

Ukucutshungulwa kwamabhodi esekethe aguquguqukayo kudlala indima ebalulekile ekunqumeni ukusebenza kahle kokukhiqiza kanye nokusebenza kahle kwezindleko.Ngokukhetha ngokucophelela izinto ezifanele kanye nezinqubo zokuklama, abakhiqizi bangakwazi ukuthuthukisa ukukhiqizwa nokuhlanganisa lawa mabhodi, banciphise isikhathi nezindleko.Izinqubo zokukhiqiza ezisebenzayo zithuthukisa ukuqina futhi zikhulise umkhiqizo, zenze amabhodi esekethe aguquguqukayo afinyeleleke kalula futhi athengeke kakhulu ezimbonini ezahlukahlukene.

Isici esisodwa sokucutshungulwa esithinta kakhulu ukusebenza kwebhodi lesifunda eliguquguqukayo yikhono layo lokumelana nokucindezeleka okushisayo.Ama-PCB avumelana nezimo ngokuvamile asetshenziswa ezindaweni ezinamazinga okushisa aphezulu noma izinguquko ezisheshayo zokushisa.Uma impahla yebhodi lesifunda ingachithi ukushisa ngokuphumelelayo, ukusebenza kwesifunda kungase kuthinteke, okuholela ekuhlulekeni okungenzeka noma ukwehluleka.Ngakho-ke, ukukhetha izinto ezine-conductivity ephezulu yokushisa kanye nokuklama izindlela zokupholisa ezifanele kubalulekile ukuze kuqinisekiswe ukwethembeka kwesikhathi eside kwamabhodi esekethe aguquguqukayo.

Esinye isici esiyinhloko esihlobene nokucutshungulwa kwamabhodi wesifunda aguquguqukayo ukuzinza kwawo kwe-dimensional.Ama-PCB aguquguqukayo avame ukuba ngaphansi kokugoba, ukusonteka nokunye ukucindezelwa komshini, okungaholela ekulimaleni noma ngisho nokwehluleka uma okokusebenza kuzinzile ngokwengxenye.Abakhiqizi badinga ukukhetha izinto zokwakha ezinama-coefficients aphansi we-thermal expansion (CTE) ukuze banciphise izinguquko ezinobukhulu ngenxa yokuguquguquka kwezinga lokushisa.Lokhu kuqinisekisa ukuthi isifunda sihlala sinjalo futhi sisebenza ngisho nangaphansi kwezimo ezimbi kakhulu zemishini.

Ukwengeza, ukuhambisana kwezinto ezisetshenziswa kumabhodi wesekethe aguquguqukayo anobuchwepheshe obuhlukahlukene bokukhiqiza kuyisici esibalulekile sokuqhubekela phambili.Abakhiqizi basebenzisa izindlela ezahlukahlukene, njengezinqubo ezingezayo noma ezikhiphayo, ukuze bakhe amaphethini wesifunda nokulandela umkhondo kulawa mabhodi.Ukukhethwa kwezinto zokwakha kumele kuhambisane nobuchwepheshe obuthile bokukhiqiza obusetshenziselwa ukuqinisekisa imiphumela emihle.Isibonelo, uma okokusebenza kungafanele kuhlelo oluthile lokukhiqiza, kungaholela ezinkingeni ezifana nokunamatheliswa kahle, i-delamination kanye nokwehluleka kwesekethe.

Ngaphezu kokucatshangelwa kokukhiqiza, ukucutshungulwa kwamabhodi esekethe aguquguqukayo nakho kuthinta ukuhlanganisa nokuhlanganiswa kwawo emishinini kagesi.Njengoba izinto zikagesi ziqhubeka ziba zincane futhi ziminyene, ikhono lokuhlanganisa ngaphandle komthungo amabhodi esekethe aguquguqukayo selibaluleke kakhulu.Abaqambi nabakhiqizi kumele baqinisekise ukuthi amabhodi esekethe angaxhunywa kalula kwezinye izingxenye noma amadivaysi, okuvumela ukuhlangana okuphumelelayo nokunciphisa amathuba okuba namaphutha noma amaphutha.

Ukuzuza ukusebenza kahle kokucubungula kwamabhodi esekethe aguquguqukayo kudinga indlela ehlukahlukene ehlanganisa isayensi yezinto zokwakha, ubuchwepheshe bokukhiqiza kanye nokucatshangelwa kwedizayini.Siyaqhubeka nokutshala imizamo ebalulekile yocwaningo nentuthuko ukuze sithuthukise ukucutshungulwa kwalawa mabhodi, sivumele ukwamukelwa kwawo ezinhlobonhlobo zezicelo.

Ngamafuphi, ukusebenza kokucubungula kwamabhodi wesifunda aguquguqukayo kuyisici esibalulekile ekunqumeni ukusebenza kwawo kanye nezicelo.Ikhono lamabhodi lokumelana nengcindezi yokushisa, ukuzinza kwe-dimensional kanye nokuhambisana nobuchwepheshe bokukhiqiza konke kuyizici ezibalulekile ekukhiqizeni ama-PCB athembekile nasebenza ngokugcwele aguquguqukayo.Ngokuqhubeka sithuthukisa amandla okucubungula amabhodi esekethe aguquguqukayo, singavula amandla awo aphelele futhi siqhubekisele phambili intuthuko kwezobuchwepheshe nobuchwepheshe.
