2m Ibhodi le-PCB elinezingqimba eziphindwe kabili lithuthukisa ubuchwepheshe be-Aerospace

Ezweni lanamuhla elithuthuke kakhulu kwezobuchwepheshe, izimboni zihlala zithuthuka futhi zisungula izinto ezintsha, futhi i-aerospace nayo injalo. Ngesidingo esikhulayo sezinhlelo ze-elekthronikhi ezisebenza kahle nezithembekile, kunesidingo samabhodi esekethe anembayo akwazi ukumelana nezidingo ezinzima zezicelo ze-aerospace.Isixazululo esinjalo esithole ukunakwa okukhulu i-Capel double layer flexible PCB enobude obungu-2m. Lobu buchwepheshe bempumelelo buye benza izinguquko endleleni amasistimu kagesi we-aerospace aklanywa futhi akhiqizwa ngayo.

Ibhodi lesifunda lomkhiqizo we-2-layer flexible liwumgogodla walobu buchwepheshe.Lawa mabhodi aklanywe ngokucophelela ukuze anikeze ukuguquguquka okuphezulu, okuwavumela ukuthi agobe futhi asonte ngaphandle kokuphazamisa ukusebenza kwawo. Ukusetshenziswa kwezinto ezithuthukisiwe nezindlela zokukhiqiza kuqinisekisa ukuthi lawa mabhodi anozinzo oluhle kakhulu lwe-thermal kanye nemishini, okuwenza athembeke kakhulu futhi afanele izimo ezimbi kakhulu ezitholakala ekusetshenzisweni kwe-aerospace.

Esinye sezici eziyinhloko zalawa mabhodi e-PCB aguquguqukayo akabili umugqa omuhle kakhulu kanye nesikhala somugqa esingu-0.15/0.15mm. Lobu bubanzi bomugqa omncane buvumela imiklamo yesekethe eyinkimbinkimbi, okuvumela ukuhlanganiswa kwezingxenye eziningi endaweni elinganiselwe. Isikhala sezintambo eziqinile siqinisekisa ukuthikamezeka kwesignali encane kanye ne-crosstalk, ngaleyo ndlela kuqinisekisa ukusebenza okungcono kakhulu kwesistimu ye-elekthronikhi.

Ukwandisa ukuthembeka kwalawa mabhodi, ubukhulu bebhodi bungu-0.23mm. Lokhu ukujiya kunikeza ibhalansi ephelele phakathi kokuguquguquka nokuqina, iqinisekisa ukuthi ibhodi lingakwazi ukumelana nokucindezeleka komshini nokudlidliza okutholakala ezinhlelweni ze-aerospace ngaphandle kokuphazamisa ukusebenza kwayo.

Isici esibalulekile sanoma iyiphi ibhodi ye-PCB ukujiya kwayo kwethusi, njengoba kuthinta ngokuqondile ukuqhutshwa kwezimpawu zikagesi. Ugqinsi lwethusi lwe-double-layer flex PCB okukhulunywa ngayo luyi-35um. Lokhu ukujiya kungaqhuba ngempumelelo amasignali kagesi futhi kuqinisekise ukusebenza okuphelele kwezinhlelo zikagesi ku-aerospace.

Esinye isici esiphawulekayo salezi zingcweti ubukhulu bembobo obuncane obungu-0.3mm. Lo sayizi wembobo encane usiza ukumba ukunemba ngesikhathi sokukhiqiza, okuvumela ukufakwa kwezingxenye ezihlukahlukene ngokunemba okuphezulu. Lokhu kuqinisekisa ukulingana okuqinile nokuxhumeka okuthembekile, okusiza ukuthuthukisa ukusebenza okuphelele nokuphila isikhathi eside kwesistimu ye-elekthronikhi.

Ukubambezeleka komlilo kubalulekile ezinhlelweni ze-aerospace ukuvimbela izingozi zomlilo.Ibhodi le-PCB elinezingqimba ezimbili lihlangabezana nezindinganiso eziqinile zokunqanda ilangabi (94V0), liqinisekisa ukuthi ngeke libambe umlilo noma lisakaze amalangabi uma kwenzeka ingozi. Lesi sici sinikeza isendlalelo esengeziwe sokuphepha, okwenza lawa mabhodi alungele izinhlelo zokusebenza ze-aerospace ebalulekile.

Ukucwiliswa kwegolide ekugcineni kuthuthukisa ukusebenza nokuphila isikhathi eside kwalawa mabhodi.Le nqubo ye-electroplating yakha ungqimba oluvikelayo phezu kwamaphedi ethusi aveziwe, ukuvimbela i-oxidation nokuqinisekisa ukuxhumana okuthembekile. Ukwelashwa kwegolide lokucwiliswa nakho kunikeza i-solderability enhle kakhulu, okwenza izingxenye zibe lula ukudayiswa ebhodini ngesikhathi somhlangano.

Ukuze kuhlangatshezwane nezidingo eziqondile zezinhlelo zokusebenza ze-aerospace, ibhodi le-PCB elinezingqimba ezimbili liyatholakala ngombala wokudambisa ongamelana nomnyama.Le nqubo ekhethekile ayigcini nje ngokujabulisa ubuhle, kodwa futhi ithuthukisa ukuqina nokuphila kwebhodi. Okumnyama futhi kusiza ukuhlonza nokuxazulula izinkinga ezingaba khona ngesikhathi sokulungiswa nokulungiswa.

Ukuqina kuyisici esibalulekile okufanele sicatshangelwe ezinhlelweni ze-aerospace.Ibhodi ye-PCB enezingqimba ezimbili yamukela i-FR4 (i-fiber yengilazi eqiniswe i-epoxy resin laminate) ukukhulisa ukuqina namandla. Lokhu kuqina akuqinisekisi kuphela ukusebenza kahle kwebhodi, kodwa futhi ubuqotho bayo besakhiwo ngaphansi kokudlidliza okunzima nokucindezeleka kwemishini.

Ubude obungu-2m buhlukile kulawa mabhodi e-PCB aguquguqukayo aphindwe kabili.Lobu bude obude buvumela ukwanda kokuguquguquka nokuguquguquka ekwakhiweni kwamasistimu kagesi ayinkimbinkimbi wezinhlelo zokusebenza ze-aerospace. Inikeza isikhala esanele sokuhlanganisa izingxenye eziningi futhi iqinisekisa umzila osebenzayo wamasiginali wokusebenza okuphezulu nokuthembeka.

Imboni ye-aerospace idinga amasistimu kagesi akwazi ukumelana nezimo ezimbi kakhulu futhi asebenze ngokungenasici ngaphandle kokuyekethisa.Ukusetshenziswa kwamabhodi e-PCB anezingqimba ezimbili kubuchwepheshe be-aerospace kunikeza isisombululo esifanele. Inhlanganisela eyingqayizivele yalezi zici ezingenhla yenza lawa mabhodi alungele i-aerospace.

I-Capel ingumkhiqizi webhodi lesifunda oguquguqukayo ohamba phambili owaziwa ngobungcweti bakhe ekukhiqizeni izixazululo ze-elekthronikhi ezisezingeni eliphezulu nezintsha. Uhlu lwethu olubanzi lwezinsizakalo luhlanganisa izifunda eziguqukayo ezisheshayo, i-flex circuit prototyping kanye nomhlangano wesifunda oguquguqukayo. Isebenzisa iminyaka yokuhlangenwe nakho kwemboni, i-Capel yenza amapuleti ahlangabezana nezindinganiso eziphakeme zemboni futhi ahlangabezane nezidingo ezithile zomkhakha we-aerospace.
Ibhodi le-PCB eliguquguqukayo le-2m ubude eliphindwe kabili le-Capel liguqula imboni ye-aerospace ngokunikeza ukusekelwa okungenakuqhathaniswa kwezobuchwepheshe. Lawa mabhodi anikeza izici ezinjengobubanzi obuhle kakhulu bomugqa nesikhala, ukujiya kwebhodi, ukujiya kwethusi, indawo encane yokuvula, ukumelana nelangabi, ukuphela kwendawo, imibala yokushisela ukumelana, ukuqina nobude obukhethekile ukuze kunikeze ukwethembeka nokusebenza okungenakuqhathaniswa. I-Capel, ngobungcweti bayo nezinsizakalo ezibanzi, ihamba phambili ekukhiqizeni lawa mashidi aphambili kanye nokuthuthukiswa kobuchwepheshe be-aerospace.
