Kodi ma rigid-flex circuit board amapangidwa bwanji?

Mu positi iyi yabulogu, tiwona momwe amapangira ma board ozungulira okhazikika ndikumvetsetsa momwe amapangidwira.

Ma board ozungulira okhwima, omwe amadziwikanso kuti matabwa osinthika osindikizidwa (PCBs), ndi otchuka mumakampani opanga zamagetsi chifukwa cha kuthekera kwawo kuphatikiza ma PCB okhwima komanso osinthika.Ma board awa amapereka mayankho apadera pamapulogalamu omwe amafunikira kusinthasintha komanso kukhazikika.

Kuti timvetsetse momwe amapangira ma board ozungulira okhazikika, tiyeni tikambirane kaye zomwe ali.Ma board ozungulira okhazikika amakhala ndi ma PCB osanjikiza angapo komanso kulumikizana kolimba kwa PCB. Kuphatikizana kumeneku kumawathandiza kuti apereke kusinthasintha kofunikira popanda kupereka chigamulo chokhazikika choperekedwa ndi mapanelo okhwima. Mapulaniwa ndi oyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo ndege, zamankhwala ndi magalimoto, kuti agwiritsidwe ntchito pazida monga zamagetsi zovala, implants zachipatala ndi masensa agalimoto.

Tsopano, tiyeni tifufuze njira yopangira ma rigid-flex circuit board. Njira yopangira matabwawa imaphatikizapo masitepe angapo, kuyambira pakupanga mapangidwe mpaka msonkhano womaliza. Nawa masitepe ofunikira:

1. Kupanga: Gawo la mapangidwe limayamba ndi kupanga mapangidwe a bolodi la dera, poganizira mawonekedwe, kukula, ndi ntchito zomwe akufuna.Okonza amagwiritsa ntchito mapulogalamu apadera kuti apange matabwa ozungulira ndikuzindikira kuyika kwa zigawo ndi njira zotsatiridwa.

2. Kusankha zinthu: Kusankha zinthu zoyenera ndizofunikira kwambiri popanga matabwa olimba.Zimaphatikizapo kusankha magawo osinthika (monga polyimide) ndi zipangizo zolimba (monga FR4) zomwe zingathe kupirira zovuta zamakina ndi kusintha kwa kutentha.

3. Kupanga gawo lapansi losinthika: Gawo losinthika limapangidwa mwanjira yosiyana isanaphatikizidwe mu bolodi lozungulira lokhazikika.Izi zimaphatikizapo kuyika kagawo kakang'ono (kawirikawiri mkuwa) kuzinthu zomwe zasankhidwa ndikuzikongoletsa kuti zipange mawonekedwe ozungulira.

4. Kupanga Mabodi Olimba: Apanso, matabwa olimba amapangidwa pogwiritsa ntchito njira zopangira PCB.Izi zimaphatikizapo njira monga kubowola mabowo, kugwiritsa ntchito zigawo zamkuwa, ndi etching kuti apange ma circuitry ofunikira.

5. Lamination: Pambuyo pa bolodi losinthika ndi bolodi lokhazikika, amapangidwa pamodzi pogwiritsa ntchito zomatira zapadera.Njira yopangira lamination imatsimikizira mgwirizano wamphamvu pakati pa mitundu iwiri ya matabwa ndipo imalola kusinthasintha m'madera ena.

6. Kujambula kwazithunzi: Gwiritsani ntchito ndondomeko ya photolithography kuti muwonetse maulendo ozungulira a matabwa osinthika ndi matabwa okhwima pamtundu wakunja.Izi zimaphatikizapo kusamutsa chithunzi chomwe mukufuna ku filimu yojambula zithunzi kapena wosanjikiza.

7. Etching ndi plating: Pambuyo pa chithunzi cha dera, mkuwa wowonekera umachotsedwa, kusiya mayendedwe ofunikira.Kenako, electroplating ikuchitika kuti kulimbikitsa kuda mkuwa ndi kupereka madutsidwe zofunika.

8. Kubowola ndi mayendedwe: Bowolani mabowo mu bolodi yozungulira kuti muyike zigawo ndi kulumikizana.Kuphatikiza apo, kuwongolera kumapangidwa kuti apange kulumikizana kofunikira pakati pa magawo osiyanasiyana a board board.

9. Msonkhano wachigawo: Pambuyo pa bolodi la dera lopangidwa, luso lapamwamba lapamwamba kapena teknoloji yodutsa m'dzenje imagwiritsidwa ntchito kukhazikitsa resistors, capacitors, madera osakanikirana ndi zigawo zina pa bolodi lozungulira lokhazikika.

10. Kuyesa ndi Kuwunika: Zigawo zikagulitsidwa ku bolodi, zimayesedwa mozama ndikuwunika kuti zitsimikizire kuti zimagwira ntchito komanso zimakwaniritsa miyezo yabwino.Izi zikuphatikiza kuyezetsa magetsi, kuyang'ana kowoneka ndi kuyang'ana kowoneka bwino.

11. Kusonkhana komaliza ndi kulongedza: Chomaliza ndikusonkhanitsa gulu lozungulira lokhazikika muzinthu zomwe mukufuna kapena chipangizocho.Izi zingaphatikizepo zina zowonjezera, nyumba ndi ma CD.

Powombetsa mkota

Njira yopangira ma board ozungulira olimba-flex imaphatikizapo njira zingapo zovuta kuchokera pakupanga mpaka msonkhano womaliza. Kuphatikizika kwapadera kwa zida zosinthika komanso zolimba kumapereka kusinthasintha kwakukulu komanso kukhazikika, kupangitsa matabwawa kukhala oyenera kugwiritsa ntchito zosiyanasiyana. Pomwe ukadaulo ukupitilirabe patsogolo, kufunikira kwa ma board ozungulira okhazikika akuyembekezeka kukula, ndipo kumvetsetsa njira zawo zopangira kwakhala kofunika kwa opanga ndi mainjiniya opanga.
