Chiyambi cha malonda

Flexible circuit board (FPC), yomwe imadziwikanso kuti flexible circuit board, flexible circuit board, kulemera kwake, makulidwe owonda, kupindika kwaulere ndi kupindika ndi zina zabwino kwambiri zimakondedwa. Komabe, kuyang'ana kwamtundu wapakhomo kwa FPC makamaka kumadalira kuyang'ana kwapamanja, komwe kumakhala mtengo wokwera komanso wotsika mtengo. Ndi chitukuko chachangu cha makampani zamagetsi, dera bolodi kamangidwe akukhala mochulukira mkulu-mwatsatanetsatane ndi mkulu-kachulukidwe, ndi miyambo Buku kudziwika njira sangathenso kukwaniritsa zofunika kupanga, ndi kudziwika basi zofooka FPC wakhala mosapeŵeka. mayendedwe a chitukuko cha mafakitale.

Flexible circuit (FPC) ndiukadaulo wopangidwa ndi United States popanga ukadaulo wa rocket mu 1970s. Ndi dera losindikizidwa lodalirika kwambiri komanso kusinthasintha kwakukulu kopangidwa ndi filimu ya polyester kapena polyimide monga gawo lapansi. Mwa kuyika mapangidwe a dera pa pepala la pulasitiki losinthasintha, chiwerengero chachikulu cha zigawo zolondola zimayikidwa mu malo opapatiza komanso ochepa. Potero kupanga dera losinthasintha lomwe limasinthasintha. Derali limatha kupindika ndikupindika mwakufuna, kulemera kopepuka, kakulidwe kakang'ono, kutayika kwabwino kwa kutentha, kuyika kosavuta, kuswa ukadaulo wolumikizirana. Mu dongosolo la dera losinthasintha, zipangizo zomwe zimapangidwira ndi filimu yotetezera, kondakitala ndi wothandizira.

chigawo cha 1, filimu yotsekera

Filimu yotsekera imapanga gawo loyambira la dera, ndipo zomatirazo zimamangirira zojambulazo zamkuwa pagawo loteteza. M'mapangidwe amitundu yambiri, ndiye amamangiriridwa ku gawo lamkati. Amagwiritsidwanso ntchito ngati chophimba chotetezera kuti ateteze dera ku fumbi ndi chinyezi, komanso kuti achepetse kupsinjika panthawi ya kusinthasintha, zojambulazo zamkuwa zimapanga chosanjikiza cha conductive.

M'mabwalo ena osinthika, zigawo zolimba zopangidwa ndi aluminiyamu kapena zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito, zomwe zingapereke kukhazikika kwa dimensional, kupereka chithandizo chakuthupi pakuyika zigawo ndi mawaya, ndi kumasula kupanikizika. Zomatira zimamangiriza gawo lolimba ku gawo losinthika. Kuonjezera apo, chinthu china nthawi zina chimagwiritsidwa ntchito m'mabwalo osinthasintha, omwe ndi zomatira, zomwe zimapangidwa ndi kuphimba mbali ziwiri za filimu yotetezera ndi zomatira. Ma laminates omatira amapereka chitetezo cha chilengedwe komanso kutsekemera kwamagetsi, komanso kuthetsa filimu imodzi yopyapyala, komanso kutha kumangiriza zigawo zingapo ndi zigawo zochepa.

Pali mitundu yambiri ya zida zafilimu zotetezera, koma zomwe zimagwiritsidwa ntchito kwambiri ndi polyimide ndi polyester. Pafupifupi 80% ya opanga madera osinthika ku United States amagwiritsa ntchito filimu ya polyimide, ndipo pafupifupi 20% amagwiritsa ntchito filimu ya polyester. Polyimide zipangizo ndi flammability, khola geometrical dimension ndipo ali mkulu misozi mphamvu, ndipo amatha kupirira kuwotcherera kutentha, poliyesitala, amatchedwanso polyethylene double phthalates (Polyethyleneterephthalate amatchedwa: PET), amene katundu thupi ndi ofanana polyimides, imakhala ndi dielectric yotsika, imatenga chinyezi pang'ono, koma sichigonjetsedwa ndi kutentha kwakukulu. Polyester ili ndi malo osungunuka a 250 ° C ndi kutentha kwa galasi (Tg) kwa 80 ° C, komwe kumalepheretsa kugwiritsidwa ntchito pa ntchito zomwe zimafuna kuwotcherera kwambiri kumapeto. Mu otsika kutentha ntchito, iwo amasonyeza rigidity. Komabe, ndizoyenera kugwiritsidwa ntchito pazinthu monga matelefoni ndi zina zomwe sizifunikira kukhudzidwa ndi malo ovuta. Polyimide insulating filimu nthawi zambiri pamodzi ndi polyimide kapena akiliriki zomatira, polyester insulating zakuthupi zambiri pamodzi poliyesitala zomatira. Ubwino kaphatikizidwe ndi zinthu ndi makhalidwe omwewo akhoza kukhala dimensional bata pambuyo kuwotcherera youma kapena pambuyo angapo laminating m'zinthu. Zina zofunika pa zomatira ndizotsika kwambiri za dielectric, kukana kwamphamvu kwambiri, kutentha kwa magalasi apamwamba komanso kuyamwa kochepa kwa chinyezi.

2. Kondakitala

Chojambula chamkuwa ndi choyenera kugwiritsidwa ntchito m'mabwalo osinthasintha, akhoza kukhala Electrodeposited (ED), kapena yokutidwa. Chojambula chamkuwa chokhala ndi magetsi chimakhala chonyezimira mbali imodzi, pomwe mbali inayo ndi yosalala komanso yosalala. Ndi chinthu chosinthika chomwe chingapangidwe mu makulidwe ambiri ndi m'lifupi, ndipo mbali yosawoneka bwino ya zojambula zamkuwa za ED nthawi zambiri amathandizidwa mwapadera kuti apititse patsogolo luso lake lolumikizana. Kuphatikiza pa kusinthasintha kwake, zojambula zamkuwa zonyezimira zilinso ndi mawonekedwe olimba komanso osalala, omwe ndi oyenera kugwiritsa ntchito omwe amafunikira kupindika kosunthika.

3. Zomatira

Kuphatikiza pa kugwiritsidwa ntchito kumangiriza filimu yotetezera kuzinthu zoyendetsera zinthu, zomatirazo zingagwiritsidwenso ntchito ngati chophimba chophimba, ngati chophimba chotetezera, komanso ngati chophimba chophimba. Kusiyanitsa kwakukulu pakati pa ziwirizi kumakhala mu ntchito yomwe imagwiritsidwa ntchito, pomwe zomangira zomwe zimamangiriridwa ku filimu yotchinga yotchinga ndikupanga dera lopangidwa ndi laminated. Ukadaulo wosindikizira pazenera womwe umagwiritsidwa ntchito popaka zomatira. Sikuti zomatira zonse zimakhala ndi zomatira, ndipo zomatira zopanda zomatira zimapangitsa kuti mabwalo azing'onoting'ono komanso kusinthasintha kwakukulu. Poyerekeza ndi kapangidwe laminated zochokera zomatira, izo ali bwino matenthedwe madutsidwe. Chifukwa cha mawonekedwe woonda wa osagwirizana ndi zomatira kusinthasintha dera, ndipo chifukwa cha kuchotsa kukana matenthedwe zomatira, potero kuwongolera matenthedwe madutsidwe, angagwiritsidwe ntchito m'malo ntchito kumene dera losinthasintha zochokera zomatira laminated dongosolo. sangathe kugwiritsidwa ntchito.

Chithandizo cha ana asanabadwe

Popanga, pofuna kupewa kutseguka kwafupipafupi kwambiri ndikupangitsa kuti pakhale zokolola zochepa kwambiri kapena kuchepetsa kubowola, kalendala, kudula ndi zovuta zina zomwe zimayambitsidwa ndi zida za FPC board, mavuto obweranso, ndikuwunika momwe mungasankhire zida kuti mukwaniritse bwino. Zotsatira zakugwiritsa ntchito kwamakasitomala ma board osinthika ozungulira, chithandizo chisanachitike ndikofunikira kwambiri.

Chithandizo chisanachitike, pali zinthu zitatu zomwe ziyenera kuchitidwa, ndipo mbali zitatuzi zimamalizidwa ndi mainjiniya. Yoyamba ndi FPC board engineering evaluation, makamaka kuyesa ngati kasitomala a FPC board angapangidwe, ngati mphamvu yopanga kampaniyo imatha kukwaniritsa zomwe kasitomala amafuna komanso mtengo wagawo; Ngati kuwunika kwa projekiti kwadutsa, chotsatira ndikukonzekera zida nthawi yomweyo kuti zikwaniritse zopangira zopangira chilichonse. Pomaliza, mainjiniya ayenera: zojambula za kasitomala wa CAD, deta ya gerber ndi zolemba zina zaumisiri zimasinthidwa kuti zigwirizane ndi malo opangira ndi mapangidwe a zida zopangira, ndiyeno zojambula zopangira ndi MI (khadi laukadaulo) ndi zida zina zimasinthidwa. kutumizidwa ku dipatimenti yopanga, kuwongolera zikalata, kugula zinthu ndi madipatimenti ena kuti alowe munjira yopangira chizolowezi.
