Chithunzi cha PCB

Mabokosi osindikizidwa amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga mauthenga, ndege, magalimoto, asilikali, mphamvu zamagetsi, chithandizo chamankhwala, kuyang'anira mafakitale, electromechanical, ndi makompyuta.Kodi kupanga PCB ndi chiyani?Kupanganso zinthu kumatchedwa kupanga.Makasitomala amaperekaKupanga kwa PCBzikalata ndi zofunika kupanga, ndi opanga PCB kupanga mankhwala malinga ndi zofunika ndi chindapusa pokonza.Kupanga kwa PCB kumatanthauza kutiOpanga PCBkuberekanso matabwa ozungulira osindikizidwa malinga ndi zofuna za makasitomala.

Chifukwa chiyani kupanga PCB ikufunika kugwira ntchito zamapaneli?Mukayika chigamba cha SMT, kodi chiyenera kudulidwa kukhala bolodi limodzi?Kodi m'mphepete mwa bolodi losindikizidwa ndi chiyani?Sizinanenedwa kuti bolodi ikagwiritsidwa ntchito mochepa, imatsika mtengo?Nthawi zambiri mapangidwe a PCB amakhala gulu la PCB, ndipo gawo loyambirira ndikuwonjezera kupanga kwa mzere wopangira chigamba cha SMT.Kulumikizana kwa PCB ndikosavuta kupanga.Kwa opanga PCB, zinthu zoyambira zama board osindikizidwa nthawi zambiri zimakhala zazikulu.matabwa ambiri amapangidwa nthawi imodzi, ndiyeno kudula mmodzimmodzi.The splicing makamaka ntchito kuwotcherera kupanga.

PCB gulu ali ntchito zingapo, amene ndi yabwino kwa makasitomala pulagi, yabwino kwa opanga PCB zabodza kupanga okha, ndi amapulumutsa zipangizo.Kupanga kwa PCB nthawi zambiri kumakhala ndi matabwa angapo, monga awiri-in-imodzi, anayi-in-imodzi, ndi zina zotero. kwenikweni mu malata mkulu kusindikiza ndondomeko, chifukwa ngakhale kukula kwabolodi losindikizidwandi yayikulu, nthawi yosindikiza ndi pafupifupi 25s.Ndiko kunena kuti, ngati makina osindikizira a chip atenga nthawi yochepa kusiyana ndi makina osindikizira a solder, amadikirira opanda kanthu.Kuchokera pakuwona phindu lazachuma, izi ndizowonongeka.

PCB gulu ali ndi mwayi wina.Iwo akhoza kupulumutsa nthawi kutola ndi kuika matabwa PCBA dera, chifukwa matabwa angapo akhoza anatola ndi kuikidwa pa nthawi yomweyo.Maola a anthu amawononga pakutolera ndi kuyika zida.

Kodi cholinga chopanga m'mphepete mwa PCB ndi chiyani?Cholinga chachikulu cha PCB m'mphepete kamangidwe ndi kuthandiza PCBA kupanga msonkhano.Mzere wamakono wopanga chigamba cha SMT ndiwodziwikiratu kwambiri, ndipo matabwa amanyamulidwa ndi malamba ndi unyolo.Cholinga chachikulu cha m'mphepete mwa bolodi ndikunyamula matabwa kupita ku malamba ndi maunyolo.Mukhozanso kusiya malo ena ozungulira bolodi ndipo osayika zida zilizonse zamagetsi.Kupanga kwa PCB nthawi zambiri kumafuna osachepera 5.0mm kapena kupitilira apo, chifukwa unyolo wachitsulo wa ng'anjo yobwereranso uyenera kugwiritsa ntchito malo ozama kwambiri m'mphepete mwa bolodi, kotero pali mwayi woti Palibe chifukwa chopangira m'mphepete mwa bolodi. , mwinamwake lamba ndi unyolo zikhoza kuwononga zipangizo zamagetsi zozungulira.
