Kubalulekile ukuqaphela ukuthi ukuqina kwamabhodi aqinile-flex kungase kuhluke kuye ngokuthi isicelo esithile.Izimboni ezifana ne-aerospace noma ezokwelashwa ngokuvamile zidinga ukuguquguquka okuqhubekayo noma okwedlulele futhi zingadinga ukucatshangelwa kwedizayini okuqinile ukuze kuqinisekiswe ukwethembeka nokuqina kwesikhathi eside. Ezimweni ezinjalo, izinyathelo ezengeziwe zingathathwa, njengokwengeza ukuqinisa okwengeziwe ezindaweni ezibucayi noma ukukhetha izinto ezinezici zokugoba ezithuthukisiwe.

Izici Zemvelo:

Ukuqina kwebhodi eliguquguqukayo eliqinile kuthonywa kakhulu amandla ayo okumelana nezinto ezizungezile ezifana nokushintsha kwezinga lokushisa, umswakama, nokudlidliza—zonke izimo ezivamile zemishini kagesi.

Ukuhamba ngebhayisikili izinga lokushisa ukuhlola okujwayelekile kokwethembeka okwenziwa kuma-PCB aguquguqukayo ukuze kuhlolwe ukumelana kwawo nokwehla kwezinga lokushisa okudlulele.Ngalezi zivivinyo, abakhiqizi bangakwazi ukubona ubuthakathaka obungaba khona ekwakhiweni kwebhodi noma ukukhetha izinto ezingase ziholele ekuhlulekeni ngaphansi kwezimo ezithile zokushisa.

Umswakamo ungaphinda uthinte ukuqina kwamabhodi aguquguqukayo. Ukuze kuthuthukiswe ukumelana kwabo, abakhiqizi bavame ukusebenzisa i-coatings ekhethekile noma i-conformal coatings ehlinzeka ngesendlalelo esengeziwe sokuvikela.Lezi zembatho zivimbela ukungena komswakama futhi zivikele i-PCB ekugqwaleni, inwebe impilo yayo yonke.

Esinye isici esibalulekile semvelo esithinta ukuqina kwe-rigid-flex ukudlidliza.Ukudlidliza kungacindezela ngokuzenzakalelayo ibhodi nezingxenye zalo, kubangele ukwehluleka kwamalungu e-solder noma ukuhlukaniswa kwengxenye. Ukunciphisa imithelela yokudlidliza, abakhiqizi bangasebenzisa amasu afana nezimbambo, izinto ezinamathelayo noma okokukhweza kwemishini ukuze kuvikeleke izingxenye kanye nokunciphisa imiphumela yokudlidliza.

Ukwengeza, uthuli, ukungcola, nokunye ukungcola kungathinta ukusebenza nokuphila isikhathi eside kwamabhodi aqinile-flex.Uma lokhu kungcola kufakwe phezu kwebhodi lesifunda, kungase kubangele amasekhethi amafushane, ukugqwala noma ukuwohloka kwe-insulation. Ukubekwa uphawu nokuvikelwa okufanele kwamabhodi esifunda, kanye nokuhlanza nokugcinwa njalo, kubalulekile ekuvimbeleni lezi zinkinga.

Ukwengeza, i-electromagnetic interference (EMI) ingathinta ukusebenza kwamabhodi aqinile-flex, ikakhulukazi ezinhlelweni lapho izingxenye ezibucayi noma amasignali amaza aphezulu ekhona.Amasu okuvikela njengezindiza eziphansi noma izimbotshana ezivikelayo zisiza ukunciphisa i-EMI futhi ziqinisekise ubuqotho bokudluliswa kwesignali ebhodini.

Umthelela wamandla angaphandle (njengomthelela noma umthelela) kumaphaneli e-rigid-flex kumele nawo ucatshangelwe.Izisetshenziswa ezingaphansi kokuphathwa kabi noma ukuthuthwa zingase zibe sengozini yokulimala ngokomzimba. Ngakho-ke, ukupakishwa okufanele, izinto ezibamba ukushaqeka, nezivalo zokuvikela kubalulekile ekugcineni ukuqina kwebhodi.

Amabhodi e-Rigid-flex enzelwe ukugoba nokugoba, kodwa ukugoba ngokweqile ezindaweni ezithile kungabeka ukucindezeleka okungadingekile ezingxenyeni nasezintweni, okuholela ekuhlulekeni kwemishini. Ngokuhlela ngokucophelela izingxenye, abaklami banganciphisa ingozi yokucindezeleka kwemishini noma ukulimala.

Izingxenye kufanele zigcinwe kude nezindawo lapho ukugoba okunzima kwenzeka khona.Ukuwabeka ezindaweni eziqinile noma ezinzile ebhodini kungasiza ekuvikeleni ekucindezelekeni okungafuneki. Futhi, kubalulekile ukucabangela ubukhulu nesisindo sezingxenye. Izingxenye ezinkulu noma ezisindayo kufanele zibekwe ezindaweni okungenzeka ukuthi zingahlangabezana nokuguquguquka ngokweqile.

I-traces kanye ne-vias yizindlela ze-conductive ebhodini ezidinga ukubekwa ngamasu.Kufanele zibekwe ezindaweni lapho mancane amathuba okuba zibe ngaphansi kwengcindezi yokugoba. Ngokugwema izindawo zokugoba ezibucayi, unciphisa ingozi yokulimala komkhondo kanye nethuba lokuvula noma izikhindi.

Ukuze kuthuthukiswe ukuqina kwamaphaneli, ama-adhesive angasetshenziswa ukubopha nokuqinisa izimbambo.Izimbambo ziyimicu emincane yezinto efakwe phakathi kwe-plies ukunikeza ukusekelwa kwesakhiwo. Ngokuhlanganisa izingxenye kanye nokulandela lezi zimbambo, ikhono lazo lokumelana nokugoba nokugoba liyathuthukiswa. I-adhesive isebenza njengesendlalelo sokuzivikela, inciphisa amathuba okulimaza izingxenye kanye nemikhondo ngesikhathi sokugoba.

Amazinga Wokuhlola Nezitifiketi:

Mayelana nokuhlola kanye nesitifiketi, amabhodi aqinile-flex adlula ezinqubweni ezihlukahlukene ukuze ahlole ukuqina nokuthembeka kwawo. Lezi zivivinyo zibalulekile ekuqinisekiseni ukuthi ibhodi liyahlangabezana nekhwalithi edingekayo kanye namazinga okusebenza.

I-IPC-6013 iyindinganiso ebalulekile elawula ukuhlolwa kwe-rigid-flex, eshicilelwe i-Printed Circuits Council (IPC).Izinga linikeza izidingo ezithile kanye nemibandela yokuhlola lawa mabhodi. Ukuthobela i-IPC-6013 kuqinisekisa ukuthi amabhodi ahlangabezana nemihlahlandlela eyamukelwa yimboni yekhwalithi nokuqina.

Ukuhlolwa kwe-Rigid-flex ngokuvamile kufaka phakathi ukuhlolwa kwemishini nogesi.Ukuhlola okomshini kuhlola amandla ebhodi lesifunda lokumelana nokugoba, ukugoba, nokunye ukucindezeleka komshini elingase libhekane nakho phakathi nokuphila kwalo okusebenzisekayo. Lokhu kuhlola kungase kuhlanganise ukugoba, ukusonta nokudlidliza ibhodi ukuze lilingise izimo zomhlaba wangempela. Linganisa ukumelana kwebhodi nalezi zingcindezi bese ubhala noma yikuphi ukwehluleka noma umonakalo.

Ukuhlolwa kukagesi kuhlola ukusebenza kukagesi nobuqotho bebhodi eliqinile eliguquguqukayo.Lokhu kuhlola kungase kuhlanganise ukuhlola ama-opens, izikhindi, izilinganiso ze-impedance, ubuqotho besignali, nokuhlola kwe-voltage/kwamanje. Ngokwenza lezi zivivinyo zikagesi, kunganqunywa ukuthi ibhodi lihlangabezana nezimfuneko zikagesi ezidingekayo futhi lisebenza kahle.

Ngaphezu kokuhlolwa kwemishini nogesi, okunye ukuhlola kungenziwa ukuze kuhlolwe izici ezithile noma izidingo zamabhodi aqinile-flex.Lokhu kungafaka ukuhlolwa kokusebenza okushisayo, ukubambezeleka komlilo, ukumelana namakhemikhali, ukumelana nomswakama kanye nokwethembeka ngaphansi kwezimo zemvelo ezinzima.
