Njira Zofunika Kwambiri pa Flex Circuit Assembly Process

Mabwalo osinthika akhala mbali yofunika kwambiri pazida zamakono zamakono. Kuchokera ku mafoni a m'manja ndi mapiritsi kupita ku zipangizo zachipatala ndi zipangizo zam'mlengalenga, mabwalo osinthika amagwiritsidwa ntchito kwambiri chifukwa cha luso lawo lopereka ntchito zowonjezereka pamene amalola mapangidwe osakanikirana komanso osinthika. Komabe, kupanga mabwalo osinthika, omwe amadziwika kuti flex circuit assembly, kumaphatikizapo njira zingapo zofunika zomwe zimafunikira kusamalitsa ndikusamalira tsatanetsatane.Mu positi iyi ya blog, tiwona njira zazikuluzikulu zomwe zikukhudzidwa ndi msonkhano wadera wa flex.

1. Kamangidwe kake:

Gawo loyamba la msonkhano wadera wa flex ndi gawo la mapangidwe ndi masanjidwe.Apa ndi pamene bolodi imapangidwira ndipo zigawo zake zimayikidwapo. Kapangidwe kake kayenera kugwirizana ndi mawonekedwe omwe akufunidwa ndi kukula kwa flex flex circuit. Mapulogalamu opanga mapulogalamu monga CAD (Computer Aided Design) amagwiritsidwa ntchito popanga ndi kuwongolera masanjidwewo, kuwonetsetsa kuti zolumikizira zonse zofunika ndi zigawo zikuphatikizidwa.

2. Kusankha zinthu:

Kusankha zinthu zolondola n'kofunika kwambiri pa msonkhano wadera wosinthasintha.Kusankhidwa kwa zinthu kumadalira zinthu zosiyanasiyana monga kusinthasintha, kukhazikika ndi ntchito yamagetsi yofunikira pa dera. Zida zomwe zimagwiritsidwa ntchito kwambiri pa msonkhano wadera wosinthika ndi filimu ya polyimide, zojambula zamkuwa, ndi zomatira. Zidazi ziyenera kufufuzidwa mosamala chifukwa khalidwe lawo limakhudza mwachindunji ntchito yonse ndi kudalirika kwa flex circuit.

3. Kujambula ndi kukokera:

Kupanga ndi kusankha zinthu zikatha, sitepe yotsatira ndikujambula ndi kujambula.Mu sitepe iyi, mawonekedwe ozungulira amasamutsidwa pazitsulo zamkuwa pogwiritsa ntchito ndondomeko ya photolithography. Chinthu chosamva kuwala chotchedwa photoresist chimakutidwa pamwamba pa mkuwa ndipo mawonekedwe ozungulira amawonekera pa icho pogwiritsa ntchito kuwala kwa ultraviolet. Pambuyo powonekera, madera osadziwika amachotsedwa ndi ndondomeko ya etching ya mankhwala, ndikusiya zizindikiro za mkuwa zomwe zimafunidwa.

4. Kubowola ndi kupanga mapangidwe:

Pambuyo pa masitepe ojambula ndi etching, dera losinthasintha limabowoleredwa ndikupangidwa.Mabowo olondola amabowoleredwa pama board ozungulira kuti akhazikike zigawo ndi zolumikizirana. Kubowola kumafuna ukadaulo komanso kulondola, chifukwa kusalinganika kulikonse kungayambitse kulumikizana kolakwika kapena kuwonongeka kwa mabwalo. Kujambula, kumbali ina, kumaphatikizapo kupanga magawo owonjezera ozungulira ndikutsata pogwiritsa ntchito kujambula komweko ndi njira yolumikizira.

5. Kuyika chigawo ndi soldering:

Kuyika kwa zigawo ndi gawo lofunika kwambiri pa msonkhano wadera wa flex.Surface Mount Technology (SMT) ndi Kupyolera mu Hole Technology (THT) ndi njira zodziwika bwino zoyika ndi kugulitsira zinthu pazigawo zosinthika. SMT imaphatikizapo kumangirira zigawo pamwamba pa bolodi, pamene THT imaphatikizapo kuyika zigawo m'mabowo obowoledwa ndi soldering mbali inayo. Makina apadera amagwiritsidwa ntchito kuti atsimikizire kuyika kwachinthu cholondola komanso mtundu wabwino kwambiri wa solder.

6. Kuyesa ndi Kuwongolera Ubwino:

Zigawo zikagulitsidwa pa flex circuit, kuyesa ndi kuwongolera khalidwe kumayendetsedwa.Kuyezetsa kogwira ntchito kumachitidwa kuti zitsimikizire kuti zigawo zonse zikugwira ntchito bwino komanso kuti palibe zotsegula kapena zazifupi. Chitani mayeso osiyanasiyana amagetsi, monga kuyesa kupitiliza ndi kuyesa kukana kutsekereza, kuti mutsimikizire kukhulupirika kwa mabwalo. Kuphatikiza apo, kuyang'ana kowoneka kumachitika kuti muwone ngati pali vuto lililonse lakuthupi kapena zolakwika.

7. Encapsulation ndi encapsulation:

Pambuyo podutsa zoyezetsa zofunikira komanso zowongolera khalidwe, flex circuit imayikidwa.Njira ya encapsulation imaphatikizapo kugwiritsa ntchito chingwe chotetezera, chomwe nthawi zambiri chimapangidwa ndi filimu ya epoxy kapena polyimide, kumadera kuti ateteze ku chinyezi, mankhwala, ndi zinthu zina zakunja. Dera lotsekedwa limayikidwa mu mawonekedwe omwe amafunidwa, monga tepi yosinthika kapena mawonekedwe opindika, kuti akwaniritse zofunikira zenizeni za mankhwala omaliza.

Powombetsa mkota:

Ndondomeko ya msonkhano wadera wa flex imaphatikizapo njira zingapo zofunika zomwe zimakhala zofunikira kwambiri kuti zitsimikizire kupanga maulendo apamwamba kwambiri.Kuchokera pakupanga ndi kusanja mpaka kuyika ndi kuyika, sitepe iliyonse imafunikira kusamalitsa mwatsatanetsatane komanso kutsatira njira zowongolera bwino. Potsatira njira zovutazi, opanga amatha kupanga mabwalo odalirika komanso osinthasintha omwe amakwaniritsa zofunikira za zipangizo zamakono zamakono zamakono.
