Mtundu wa BB wosinthasintha, wotchedwa BB Flex PCB, imakhala ndi filimu yoteteza polyimide komanso mtundu wosindikizidwa. Ma polyimides ndi ma insulators, chifukwa chake njirayo imatha kumalizidwa pokhapokha ngati magawo azoyendetsa bwino. Monga “chigoba chowotcherera” cha PCB chokhwima, PCB yosinthasintha imakutidwa ndi “yokutidwa” kocheperako komwe kumatsekereza dera kuti lisasokonezeke ndi magetsi. Flex PCB tsopano ikupezeka pa foni yamankhwala komanso ntchito zamankhwala, makamaka ma circuits amasintha kwambiri kutentha ndikukhala osinthasintha.

Ma PCBS osinthika amaonedwa kuti ndi “osinthika” pazifukwa zosiyanasiyana. Chowonekera kwambiri ndikuti madera awo amatha kusintha kuti agwirizane ndi malonda omwewo. Izi ndizopindulitsa makamaka zikafika pamagawo monga kukhazikika, kukhazikika, kulemera pang’ono komanso kusinthasintha. Mabungwe azikhalidwe zadongosolo sangathe kukwaniritsa miyezo yokhazikika, yolimba komanso kuchita bwino.

Ma board osinthika ndi apamwamba kuposa matabwa achikhalidwe pankhani yazoperewera pazogulitsa. Mwachitsanzo, kugwiritsa ntchito PCB yosinthika m’malo mokhazikika kumatha kuchepetsa kwambiri kukula kwa chinthucho. Zitha kupindika ndikupindika kuti zigwirizane ndi zomwe zili pachimake. Chogulitsa chonsecho chikhoza kupangidwa chopepuka pogwiritsa ntchito zigawo zofanana ndi zolimba komanso zolemetsa. However, flexible plates are not completely flexible. Ma PCBS awa ali ndi malo olimba, koma oyang’anira amayikidwa makamaka pazinthu zosunthika, kotero zimatha kusintha malinga ndi malonda. Sungani zigawo zolimba zomwe zimagwiritsidwa ntchito pothandizira zinthu kuti zikhale zotsika kwambiri.

1. Ntchito yomanga:

PCB yosinthika yomwe ingafanane ndi kukhazikika kwake imatha kupangidwa m’njira zingapo. Malinga ndi ukadaulo, mulingo ndi zakuthupi, timawagawa motere:

Dera lokhazikika lokhalo limodzi (SSFC) limakhala ndi gawo limodzi lokhala ndi chitsulo chosungunula chitsulo kapena chitsulo pafilimu yosinthika yama dielectric; Kawirikawiri polyimide imagwiritsa ntchito njira ya THT (kupyolera-bowo) kuti ikhazikitse chigawocho, zomwe zikutanthauza kuti mungagwiritse ntchito mbali imodzi kuti musinthe ndikusintha chigawocho. PCB yosinthika ya mbali imodzi yokhala ndi zokutira kapena popanda zotchingira zitha kupangidwa pogwiritsa ntchito filimu yotchingira; Komabe, kugwiritsa ntchito chovala chotchinga pakompyuta ndizofala kwambiri chifukwa chimalepheretsa dera ndi EMI iliyonse. The structure and insulation of a single-layer flexible PCB are explained as follows:

Sculpted flexible PCB ndi gawo lowoneka bwino la PCB losinthika, zomwe zidapangidwa pano zikugwirizana ndi njira yosinthika yosinthika yomwe imapanga mawonekedwe osinthika okhala ndi ma conductor amkuwa a makulidwe osiyanasiyana kutalika kwake. The conductor is thinner in the flexible region and thicker in the rigid region. This method involves selective etching of copper foil to obtain depth in various areas of the circuit.

Zojambula zosinthika za PCB nthawi zambiri zimasankhidwa kuti zipange zolumikizira zopanda zitsulo kuti izi zitheke. Zimachokera m’mphepete mpaka polumikizira. Dera lowonjezeka limapangitsa malo olumikizirana kukhala olimba kuti akhale okhazikika komanso olimba kuposa ma circuits wamba osinthika.

Multilayer PCB yosinthika imakhala ndi dera lomwelo losinthika lomwe lili ndi zigawo zingapo. Zigawozi zimalumikizidwa ndi mbale zafulati. Zigawo za Mipikisano wosanjikiza flexible PCB mosalekeza laminated kudzera mabowo. Ma PCBS amitundu yambiri ndi ofanana ndi PCBS yamitundu ingapo kupatula kusiyana kwa zinthu, mtundu, mawonekedwe, ndi mtengo. Maseketi angapo osanjikiza ndiokwera mtengo kuposa anzawo, koma onetsetsani kuti ali bwino. Pansipa pali kuwonetseredwa kwa ma PCB angapo.

Gawo lokhalo lokhazikika ndilo gawo lomwe limagwiritsidwa ntchito polumikizana. Zina zonse za gulu la dera zimasinthasintha.

2. ntchito:

Flexible PCBS imagwiritsidwa ntchito m’malo otsatirawa:

Matabwa osindikizidwa osinthika nthawi zambiri amagwiritsidwa ntchito pakakhala kudalirika, kusinthasintha komanso zinthu zopepuka, monga momwe zimakhalira ndi zida zamankhwala. Piritsi yomeza kamera yotchedwa Pill Cam imagwiritsa ntchito dera locheperako kwambiri lomwe liyenera kukhala lotetezedwa bwino komanso lolimba. Pambuyo pomeza mapiritsi, madokotala ndi akatswiri amatha kuwona bwino minofu kuchokera mkati mwa thupi. Mapiritsiwa amafunika kukhala ochepa kwambiri ndipo amayenera kusunthika mthupi lonse, ma PCBS osunthika ndi chisankho chabwino, mosiyana ndi okhwima komanso osakhwima.

B) Mafoni anzeru:

Kufunika kwa mafoni “anzeru” kumafuna kuti mafoni azikhala ndi tizinthu ting’onoting’ono komanso ma circuits osinthika. Chifukwa chake, ma PCBS osinthika amatenga gawo lofunikira pama circuits omwe amagwiritsidwa ntchito m’malo ena ofunikira, monga “ma amplifiers amagetsi”. Chifukwa chake mafoni amatha kukhala anzeru komanso opepuka.

C) Zamagetsi Zamakompyuta:

Zida zamagetsi zomwe zili mu boardboard ndizo maziko ndi moyo wamakompyuta amakono. Mapangidwe ozungulira ayenera kukhazikitsidwa pang’ono, mwachidule. Chifukwa chake, matabwa osinthasintha amagwiritsidwa ntchito kusunga chilichonse kukhala chokhazikika komanso chaching’ono.
