Izinyathelo Ezibalulekile Enqubweni Yomhlangano Wesifunda Se-Flex

Amasekhethi aguqukayo abe yingxenye ebalulekile yemishini yesimanje kagesi. Kusukela kuma-smartphone namathebulethi kuya kumadivayisi ezokwelapha kanye nemishini ye-aerospace, amasekhethi aguquguqukayo asetshenziswa kakhulu ngenxa yekhono lawo lokuhlinzeka ngokusebenza okuthuthukisiwe kuyilapho evumela imiklamo ehlangene futhi eguquguqukayo. Kodwa-ke, inqubo yokukhiqiza yamasekethe aguquguqukayo, eyaziwa ngokuthi umhlangano wesifunda oguquguqukayo, ibandakanya izinyathelo ezimbalwa ezibucayi ezidinga ukuphathwa ngokucophelela nokunaka imininingwane.Kulokhu okuthunyelwe kwebhulogi, sizohlola izinyathelo ezibalulekile ezihilelekile kunqubo yomhlangano wesifunda oguquguqukayo.

1. Isakhiwo sedizayini:

Isinyathelo sokuqala ekuhlanganiseni kwesifunda se-flex yisigaba sokuklama nokuhlela.Yilapho ibhodi lakhiwe khona futhi izingxenye zalo zibekwe kulo. Isakhiwo kufanele sihambisane nesimo esifunwayo kanye nosayizi wesekhethi yokugcina eguquguqukayo. Isofthiwe yokuklama efana ne-CAD (I-Computer Aided Design) isetshenziselwa ukwakha kanye nokushintsha isakhiwo, ukuqinisekisa ukuthi konke ukuxhumeka okudingekayo nezingxenye zifakiwe.

2. Ukukhetha okubalulekile:

Ukukhetha impahla efanele kubalulekile ngesikhathi somhlangano wesifunda oguquguqukayo.Ukukhethwa kwezinto kuncike ezintweni ezihlukahlukene ezifana nokuguquguquka, ukuqina nokusebenza kukagesi okudingekayo kumjikelezo. Izinto ezivame ukusetshenziswa emhlanganweni wesifunda oguquguqukayo zihlanganisa ifilimu ye-polyimide, ucwecwe lwethusi, nezinamatheliso. Lezi zinto zidinga ukukhishwa ngokucophelela njengoba ikhwalithi yazo ithinta ngokuqondile ukusebenza okuphelele nokuthembeka kwe-flex circuit.

3. Ukuthwebula nokunamathisela:

Uma ukuklama nokukhethwa kwempahla sekuqediwe, isinyathelo esilandelayo ukuthwebula nokuqopha.Kulesi sinyathelo, iphethini yesifunda idluliselwa ku-foil yethusi kusetshenziswa inqubo ye-photolithography. Into ezwela ukukhanya ebizwa ngokuthi i-photoresist imbozwe endaweni yethusi futhi iphethini yesekethe ivezwa kuyo kusetshenziswa ukukhanya kwe-ultraviolet. Ngemva kokuchayeka, izindawo ezingavezwanga zisuswa ngenqubo yokufaka amakhemikhali, kushiye imikhondo yethusi efunwayo.

4. Ukubhoboza nokwenza iphethini:

Ngemuva kwezinyathelo ze-imaging kanye ne-etching, i-flex circuit i-drilled futhi iphethini.Izimbobo zokunemba zimbozwa emabhodini esekethe ukuze kubekwe izingxenye kanye nezixhumanisi. Inqubo yokumba idinga ubuchwepheshe kanye nokunemba, njengoba noma yikuphi ukungahambi kahle kungaholela ekuxhumekeni okungalungile noma ukulimala kumasekhethi. Iphethini, ngakolunye uhlangothi, ihilela ukudala izendlalelo zesekethe ezengeziwe kanye nemikhondo kusetshenziswa inqubo efanayo yokuthwebula nokufaka.

5. Ukubekwa kwengxenye kanye ne-soldering:

Ukubekwa kwengxenye kuyisinyathelo esibalulekile emhlanganweni wesifunda oguquguqukayo.I-Surface Mount Technology (SMT) kanye ne- Through Hole Technology (THT) izindlela ezivamile zokubeka nokuhlanganisa izingxenye kumasekethe aguquguqukayo. I-SMT ihlanganisa ukunamathisela izingxenye ngokuqondile ebusweni bebhodi, kuyilapho i-THT ihilela ukufaka izingxenye ezimbotsheni ezibhoboziwe kanye nokunamathisela ngakolunye uhlangothi. Imishini ekhethekile isetshenziselwa ukuqinisekisa ukubekwa kwengxenye enembile kanye nekhwalithi engcono kakhulu ye-solder.

6. Ukuhlola Nokulawula Ikhwalithi:

Uma izingxenye sezidayiselwe kumjikelezo oguqukayo, izinyathelo zokuhlola nekhwalithi ziyasetshenziswa.Ukuhlola okusebenzayo kwenziwa ukuze kuqinisekiswe ukuthi zonke izingxenye zisebenza kahle nokuthi awekho ama-open noma izikhindi. Yenza izivivinyo ezihlukene zikagesi, ezifana nokuhlola ukuqhubeka nokuhlola ukumelana nokufakwa kwe-insulation, ukuze kuqinisekiswe ubuqotho bamasekhethi. Ukwengeza, ukuhlolwa okubonakalayo kuyenziwa ukuze kuhlolwe noma yikuphi ukukhubazeka ngokomzimba noma okungavamile.

7. I-encapsulation kanye ne-encapsulation:

Ngemuva kokudlula ukuhlolwa okudingekayo kanye nezinyathelo zokulawula ikhwalithi, i-flex circuit ihlanganiswe.Inqubo ye-encapsulation ihilela ukusebenzisa isendlalelo sokuzivikela, ngokuvamile esenziwe ngefilimu ye-epoxy noma i-polyimide, kumjikelezo ukuze ivikeleke kumswakama, amakhemikhali, nezinye izakhi zangaphandle. Umjikelezo ohlanganisiwe ube usuhlanganiswa efomini elifunwayo, njenge-tape eguquguqukayo noma isakhiwo esigoqiwe, ukuze kuhlangatshezwane nezidingo ezithile zomkhiqizo wokugcina.

Ngokufigqiwe:

Inqubo yomhlangano wesifunda we-flex ihilela izinyathelo ezimbalwa ezibucayi ezibalulekile ukuze kuqinisekiswe ukukhiqizwa kwe-high quality flex circuits.Kusukela ekuklanyweni nasekuhleleni kuya ekupakishweni nasekupakisheni, isinyathelo ngasinye sidinga ukunakwa ngokucophelela emininingwaneni kanye nokuhambisana nezinyathelo eziqinile zokulawula ikhwalithi. Ngokulandela lezi zinyathelo ezibucayi, abakhiqizi bangakhiqiza amasekhethi aguquguqukayo athembekile futhi asebenza ngempumelelo ahlangabezana nezidingo zemishini kagesi ethuthukisiwe yanamuhla.
