4 Layer FPC+FR4 Rigid Flex PCB
Malamulo Opanga Ndi Kusamala Kwa Rigid Flex PCB
Mapangidwe a okhwima flex PCB ndi ovuta kwambiri kuposa mapangidwe achikhalidwe a PCB, ndipo pali malo ambiri oti mumvetsere.Makamaka, malo osinthika okhwima osinthika, komanso mawaya okhudzana nawo, mapangidwe a dzenje, onse ayenera kutsatira zofunikira za malamulo ogwirizana nawo.
1. Kudzera dzenje malo
Pogwiritsa ntchito mphamvu, makamaka pamene mbale yofewa nthawi zambiri imapindika, kupyola mabowo pa mbale yofewa kuyenera kupeŵedwa momwe zingathere, zomwe zimakhala zosavuta kuwonongeka ndi kusweka.Komabe, mabowo amatha kuponyedwa m'malo olimbikitsa a bolodi lofewa, koma mzere wa m'mphepete mwa malo olimbikitsanso uyenera kupeŵa.Choncho, pakupanga okhwima flex PCB, pobowola, m'pofunika kupewa mtunda wina kuchokera osakaniza dera.
2. Mapangidwe a pad ndi kudzera
Pamene pad ndi kudzera mukukumana ndi zofunikira zamagetsi, mtengo wapamwamba udzapezedwa.Kulumikizana pakati pa pad ndi kondakitala kumatengera njira yosinthira yosalala kuti mupewe ngodya yolondola.Pad yodziyimira payokha iyenera kuwonjezeredwa ndi chala kuti kulimbikitsa ntchito yothandizira.
3. Kupanga ma waya
Pamalo osinthasintha, ngati pali mizere pamagawo osiyanasiyana, yesetsani kupewa mzere umodzi pamwamba ndi mzere wina pansi.Mwa njira iyi, pamene bolodi losinthika likugwedezeka, kupanikizika kwa zigawo zapamwamba ndi zapansi za pepala lamkuwa sizikugwirizana, zomwe zimakhala zosavuta kuwononga makina pamzere.M'malo mwake, iyenera kugwedezeka ndipo njira ziyenera kudutsa.
4. Kuyika kwa mkuwa
Pamapindika opindika a mbale yolimba yokhazikika, mawonekedwe abwino kwambiri ndi ma mesh.Koma pakuwongolera kwa impedance kapena ntchito zina, mawonekedwe amagetsi amtundu wa netiweki siwokhutiritsa.Chifukwa chake, wopangayo amayenera kupanga chigamulo choyenera kuti agwiritse ntchito pepala lamkuwa la netiweki kapena mkuwa wolimba molingana ndi kapangidwe kake.
5. Mtunda pakati pa dzenje lobowola ndi pepala lamkuwa
Mtunda uwu umatanthawuza mtunda wa pakati pa dzenje ndi pepala lamkuwa.Timachitcha kuti "hole copper distance".Zinthu za flex PCB ndizosiyana ndi za PCB zolimba, kotero kuti zimakhala zovuta kuthana ndi mtunda wothina kwambiri wamkuwa.Nthawi zambiri, mtunda wa mkuwa wa dzenje uyenera kukhala 10mil.
6. Mapangidwe a zone yosakanikirana yosinthasintha
Pamalo olumikizirana okhazikika, PCB yosinthika imapangidwa bwino kuti ilumikizane ndi PCB yolimba pakati pa stack.The flex PCB kupyola-bowo m'dera lokhazikika lolumikizana limatengedwa ngati dzenje lokwiriridwa.
