Mune ino blog positi, isu tichaongorora zvinhu zvinoshandiswa mumaPCB anochinjika uye kunyura mukati mekuvaka maitiro, tichiratidza inoshamisa tekinoroji kuseri kweaya anochinja-chinja mabhodhi edunhu.
Flexible akadhindwa edunhu mabhodhi (PCBs) akachinja indasitiri yemagetsi nekupa imwe inochinjika kune yechinyakare PCBs dzakaomarara. Kuvakwa kwayo kwakasiyana uye zvigadzirwa zvinovandudza dhizaini kuchinjika, kuvimbika uye kuita.
Zvishandiso zvinoshandiswa mumabhodhi edunhu akadhindwa
Flexible PCBs anogadzirwa kubva musanganiswa wezvinhu zvakasiyana kuti awedzere kuchinjika uye kusimba. Ngatitarisei zvakanyanya zvimwe zvezvinhu zvakakosha zvakashandiswa mukuvakwa kwayo:
1. Base zvinhu:
Nheyo yechero inoshanduka PCB ndiyo substrate zvinhu. Zvishandiso zvinowanzo shandiswa zvinosanganisira polyimide (PI), inochinjika zvakanyanya uye inodzivirira tembiricha polymer. PI ine yakanakisa mechaniki simba, makemikari kuramba uye insulation zvivakwa. Imwe yakakurumbira substrate zvinhu ipolyester (PET), iyo inopa kuchinjika pamutengo wakaderera. Zvishandiso izvi zvinobvumira mapuranga edunhu kukotama, kumonyoroka uye kuchinjika kune akasiyana maumbirwo nehukuru.
2. Conductive zvinhu:
Kuti ugadzire magetsi ekubatanidza pakati pezvinhu zvakasiyana-siyana zvedunhu, conductive zvinhu zvakadai semhangura zvinoshandiswa. Mhangura yakanakisa kondakita yemagetsi ine yakanaka kuchinjika uye yakakodzera kushandiswa mumabhodhi edunhu anochinjika akadhindwa. Nhete yemhangura foil inoiswa laminated kune substrate kuti iite masekete uye zviteshi zvinodiwa pakubatanidza magetsi.
3. Nyaya yekufukidza:
Iyo yakafukidzirwa zvinhu inoshanda seyedziviriro layer pane inochinjika PCB. Ivo vanopa insulation, kuchengetedzwa kwemichina, uye kuramba kune zvakatipoteredza zvinhu zvakaita sehunyoro, guruva, uye makemikari. Polyimide overlays inoshandiswa zvakanyanya nekuda kwekugadzikana kwayo kwekushisa, kushanduka uye kusimba.
Tekinoroji yekuvaka yemabhodhi anochinjika akadhindwa edunhu
Nzira yekuvaka yePCB inoshanduka inosanganisira matanho akati wandei. Ngationgororei nhanho imwe neimwe zvakadzama:
1. Kugadzirira substrate:
Nhanho yekutanga mukuvaka PCB inoshanduka ndeyekugadzirira substrate zvinhu. Iyo yakasarudzwa substrate zvinhu, ingave polyimide kana polyester, inorapwa kuti iwedzere kushata kwayo uye inonamira zvinhu. Kurapa uku kunofambisa kusungirirwa kwezvinhu conductive kune substrate.
2. Circuit design uye marongerwo:
Tevere, shandisa komputa-inobatsira dhizaini (CAD) software kugadzira dhizaini dhizaini uye marongero. Dhizaini inosarudza kuiswa kwezvikamu zvemagetsi pabhodhi redunhu uye nzira yekubatanidza magetsi. Iyi nhanho inoda kunyatsotariswa kwezvinhu zvakaita sechiratidzo chekuvimbika, kugovera kwemagetsi, uye kutonga kwekupisa.
3. Etching uye plating:
Mushure mekugadzirwa kwedunhu kwapera, iyo etching process inoitwa pane substrate. Shandisa kemikari mhinduro kusarudza kubvisa yakawandisa mhangura, uchisiya inodiwa yedunhu traces nemapads. Mushure mekucheka, bhodhi redunhu rinoputirwa nehutete hwakatsetseka hwemhangura, iyo inowedzera nzira yekufambisa uye inovimbisa kugadzikana kwemagetsi.
4. Solder mask uye kudhinda skrini:
Solder mask inzvimbo yekudzivirira iyo inoshandiswa pamusoro pebhodhi redunhu. Inodzivirira mitsetse yemhangura kubva kune oxidation, solder bridging, uye zvimwe zvekunze zvinofurira. Inobva yadhindwa skrini kuti iwedzere mamaki, senge chikamu chemavara kana polarity zviratidzo, kufambisa kuungana uye kugadzirisa matambudziko.
5. Kuiswa kwechikamu uye kusangana:
Zvigadzirwa zvemagetsi zvakaiswa pamaPCB anochinjika uchishandisa otomatiki pamusoro pekukwira tekinoroji (SMT) michina kana manyorerwo ekugadzira magadzirirwo. Solder iyo midziyo kumapadhi uchishandisa nzira dzekutengesa senge reflow kana wave soldering. Nyatsoteerera kuti ive nechokwadi chekuti zvikamu zvakarongeka uye zvakachengeteka zvakabatana.
6. Kuedza uye kuongorora:
Kana bhodhi redunhu raunganidzwa, rinopfuura nemuyedzo yakaoma uye yekuongorora maitiro kuti ive nechokwadi chekushanda kwayo uye mhando. Ita bvunzo dzeotomatiki dzakaita seIn-Circuit Testing (ICT) kana Automated Optical Inspection (AOI) kuona chero hurema hunogona kuitika kana kubatanidza kusina kunaka. Iyi bvunzo inobatsira kuona nekugadzirisa matambudziko chigadzirwa chekupedzisira chisati chatumirwa.
Flexible PCBs yave sarudzo yekutanga yezvishandiso uko zvipingamupinyi zvenzvimbo, kudzikisa uremu uye kuchinjika kwakakosha. Zvishandiso zvaro zvakasarudzika uye hunyanzvi hwekuvaka hunobvumira kugadzirisa, kuderedzwa saizi uye kukwidziridzwa kushanda. Kubva kuindasitiri yezvemuchadenga kuenda kumidziyo yekurapa uye zvemagetsi zvevatengi, maPCB anochinjika akasiya chiratidzo chavo munzvimbo dzakasiyana siyana.
Muchidimbu
Flexible PCBs inopa huwandu hwezvakanakira nekuda kwechimiro chavo uye zvinhu.Iko kusanganiswa kwezvinhu zvepasi, conductive zvinhu uye chifukidzo chekudzivirira chinovimbisa kuchinjika, kusimba uye kuvimbika. Kunzwisisa magadzirirwo ekuvaka kwemabhodhi akadhindwa edunhu kunotipa nzwisiso kune inoshamisa tekinoroji kuseri kweaya madhipatimendi edunhu mabhodhi. Sezvo tekinoroji ichienderera mberi, maPCB anochinjika acharamba achiita basa rakakosha mukuumba ramangwana reindasitiri yemagetsi.
