Ubuchwepheshe bokukhiqiza bamabhodi esekethe aphrintiwe aqinile

Kulokhu okuthunyelwe kwebhulogi, sizohlola ubuchwepheshe obuhlukahlukene bokukhiqiza obusetshenziselwa ukukhiqiza ama-PCB aqinile futhi sihlole ukubaluleka kwawo enqubweni yokukhiqiza.

Amabhodi esekethe aphrintiwe aqinile (ama-PCB) aya ngokuya eduma embonini yezogesi ngenxa yezinzuzo zawo eziningi ngaphezu kwama-PCB endabuko aqinile noma aguquguqukayo. Lawa mabhodi amasha ahlanganisa ukuguquguquka nokuqina, okuwenza alungele izinhlelo zokusebenza lapho isikhala silinganiselwe futhi ukuqina kubalulekile. Ukukhiqiza amabhodi e-rigid-flex kuhlanganisa ubuchwepheshe obuhlukahlukene ukuze kuqinisekiswe ukwakhiwa okuphumelelayo nokuhlanganisa amabhodi esekethe.

1. Ukucatshangelwa kwedizayini nokukhetha okubalulekile:

Ngaphambi kokuqala ukubheka kubuchwepheshe bokukhiqiza, ukwakheka nezinto ezibonakalayo zama-PCB aguquguqukayo kufanele kucatshangelwe. Idizayini kufanele ihlelwe ngokucophelela, kucatshangelwe ukusetshenziswa okuhlosiwe kwebhodi, izidingo zokuvumelana nezimo, kanye nenani lezendlalelo ezidingekayo. Ukukhethwa kwezinto ezibonakalayo kubaluleke ngokufanayo njengoba kuthinta ukusebenza okuphelele nokuthembeka kwebhodi. Ukunquma inhlanganisela efanele yama-substrates aguquguqukayo futhi aqinile, okunamathelayo, nezinto zokuqhuba kubalulekile ukuze kuqinisekiswe imiphumela oyifunayo.

2. Ukwenziwa kwesekethe eguquguqukayo:

Inqubo yokukhiqiza isekethe eguquguqukayo ihlanganisa ukudala izendlalelo eziguquguqukayo usebenzisa ifilimu ye-polyimide noma i-polyester njenge-substrate. Le filimu ibhekana nochungechunge lwezinqubo ezifana nokuhlanza, ukumboza, ukuthwebula izithombe, i-etching kanye ne-electroplating ukwenza iphethini yesifunda oyifunayo. Isendlalelo esiguquguqukayo sibe sesihlanganiswa nesendlalelo esiqinile ukuze kwakheke i-PCB eguquguqukayo ephelele.

3. Ukwenziwa kwesekethe eqinile:

Ingxenye eqinile ye-rigid-flex PCB ikhiqizwa kusetshenziswa amasu okukhiqiza e-PCB endabuko. Lokhu kuhlanganisa izinqubo ezifana nokuhlanza, ukuthwebula izithombe, ukunamathisela kanye nokucwecwa kwama-laminates aqinile. Ungqimba oluqinile lube seluqondaniswa futhi luhlanganiswe nongqimba oluguquguqukayo kusetshenziswa ingcina ekhethekile.

4. Ukubhoboza nokucwenga:

Ngemva kokwakhiwa kwamasekhethi aguquguqukayo futhi aqinile, isinyathelo esilandelayo ukubhoboza izimbobo ukuvumela ukubekwa kwengxenye nokuxhumeka kukagesi. Ukubhoboza izimbobo ku-PCB eguquguqukayo eqinile kudinga ukuma okunembile ukuze kuqinisekiswe ukuthi izimbobo ezingxenyeni ezigobile neziqinile ziqondile. Ngemuva kokuthi inqubo yokubhoboza isiqediwe, izimbobo zimbozwa ngezinto zokuqhuba ukuze kusungulwe ukuxhumana kukagesi phakathi kwezingqimba ezihlukene.

5. Ukuhlanganiswa kwezingxenye:

Ukuhlanganiswa kwezingxenye kuma-PCB aqinile-flex kungaba inselele ngenxa yenhlanganisela yezinto eziguquguqukayo neziqinile. I-Traditional surface mount technology (SMT) isetshenziselwa izingxenye eziqinile, kuyilapho ubuchwepheshe obuthile obufana ne-flex bonding kanye ne-flip-chip bonding busetshenziselwa izindawo eziguquguqukayo. Lezi zindlela zidinga opharetha abanekhono kanye nemishini ekhethekile ukuze kuqinisekiswe ukuthi izingxenye zifakwe ngendlela efanele ngaphandle kokubangela noma yikuphi ukucindezeleka ezingxenyeni eziguquguqukayo.

6. Ukuhlola nokuhlola:

Ukuqinisekisa ikhwalithi nokuthembeka kwamabhodi aqinile-flex, ukuhlolwa okuqinile nezinqubo zokuhlola kuyadingeka. Yenza izivivinyo ezihlukahlukene ezinjengokuhlola ukuqhubeka kukagesi, ukuhlaziya ubuqotho besignali, ukuhamba ngebhayisikili elishisayo nokuhlola ukudlidliza ukuze uhlole amandla okusebenza ebhodi lesifunda. Ukwengeza, yenza ukuhlola okubonakalayo okuphelele ukuze uhlole noma yikuphi ukukhubazeka noma okudidayo okungase kuthinte ukusebenza kwebhodi.

7. Isiphetho sokugcina:

Isinyathelo sokugcina sokukhiqiza i-PCB eguquguqukayo eqinile ukusebenzisa i-coating yokuvikela ukuvikela ukujikeleza ezicini zemvelo ezifana nomswakama, uthuli, nokushintshashintsha kwezinga lokushisa. Ama-coatings nawo adlala indima ebalulekile ekuthuthukiseni ukuqina nokumelana kwebhodi.

Ngokufigqiwe

Ukukhiqiza amabhodi e-rigid-flex kudinga inhlanganisela yamasu okukhiqiza akhethekile nokucatshangelwa ngokucophelela. Kusukela ekuklanyeni nasekukhethweni kwezinto ezibonakalayo kuya ekukhiqizeni, ukuhlanganiswa kwengxenye, ukuhlola nokuqeda, zonke izinyathelo zibalulekile ukuze uqinisekise ukusebenza nokuphila isikhathi eside kwebhodi lakho lesifunda. Njengoba imboni yezogesi iqhubeka nokuthuthuka, ubuchwepheshe bokukhiqiza obuthuthuke kakhulu futhi obusebenza kahle kulindeleke ukuthi buqhubeke nokugqugquzela ukuthuthukiswa kwamabhodi aqinile, avule amathuba amasha okusetshenziswa kwawo ezinhlelweni ezihlukahlukene ezisezingeni eliphezulu.
