PCBA amatanthauza ndondomeko kukwera, kuyika ndi soldering anabala PCB zigawo zikuluzikulu.Njira yopanga PCBA iyenera kudutsa njira zingapo kuti amalize kupanga.Tsopano, PCBFuture adzayambitsa njira zosiyanasiyana za kupanga PCBA.
Njira zopangira PCBA zitha kugawidwa m'njira zingapo zazikulu, kukonza chigamba cha SMT→kukonza pulagi ya DIP→kuyesa kwa PCBA→kusonkhanitsa zinthu zomaliza.
Choyamba, SMT chigamba processing ulalo
Kachitidwe ka SMT chip processing ndi: solder phala kusakaniza→ solder phala kusindikiza→SPI→kukweza→reflow soldering→AOI→kukonzanso
1, kusakaniza phala la solder
Pambuyo pochotsa phala la solder mufiriji ndi kusungunuka, amalimbikitsidwa ndi dzanja kapena makina kuti agwirizane ndi kusindikiza ndi kutsekemera.
2, kusindikiza kwa solder
Ikani phala la solder pa stencil, ndipo gwiritsani ntchito squeegee kusindikiza phala la solder pa mapepala a PCB.
3, SPI
SPI ndiye chowunikira cha solder paste, chomwe chimatha kuzindikira kusindikizidwa kwa solder phala ndikuwongolera kusindikiza kwa solder phala.
4. Kukwera
Zigawo za SMD zimayikidwa pa feeder, ndipo mutu wa makina oyika amayika molondola zigawozo pa feeder pa PCB pads kudzera pakuzindikiritsa.
5. Reflow soldering
Dulani bolodi la PCB lokwera kudzera muzitsulo zotsitsimutsa, ndipo phala-ngati solder phala limatenthedwa kuti likhale lamadzimadzi kupyolera mu kutentha kwakukulu mkati, ndipo potsirizira pake itakhazikika ndikukhazikika kuti mutsirize kugulitsa.
6.AOI
AOI ndi automatic optical inspection, yomwe imatha kuzindikira momwe PCB board ikuwotchera posanthula, ndikuzindikira zolakwika za bolodi.
7. kukonza
Konzani zolakwika zomwe zapezeka ndi AOI kapena kuyang'ana pamanja.
Kachiwiri, DIP plug-in processing ulalo
Njira yopangira plug-in ya DIP ndi: plug-in → wave soldering → kudula phazi → njira yowotcherera positi → bolodi lochapira → kuyang'anira khalidwe
1, pulogalamu yowonjezera
Pangani zikhomo za zida za pulagi ndikuziyika pa bolodi la PCB
2, kutentha kwamphamvu
Bolodi yomwe idalowetsedwa imayikidwa ndi ma wave soldering.Pochita izi, malata amadzimadzi amathiridwa pa bolodi la PCB, ndipo pamapeto pake amazizidwa kuti amalize kugulitsa.
3, kudula mapazi
Zikhomo za soldered board ndi zazitali kwambiri ndipo ziyenera kudulidwa.
4, positi kuwotcherera processing
Gwiritsani ntchito chitsulo chosungunuka chamagetsi kuti mugulitse pamanja zigawozo.
5. Tsukani mbale
Pambuyo pakuwotchera, bolodi lidzakhala lodetsedwa, chifukwa chake muyenera kugwiritsa ntchito madzi ochapira ndi thanki yochapira kuti muyeretse, kapena kugwiritsa ntchito makina kuyeretsa.
6, kuyang'anira khalidwe
Yang'anani bolodi la PCB, zinthu zosayenerera ziyenera kukonzedwa, ndipo ndi zinthu zoyenerera zokha zomwe zingalowe munjira ina.
Chachitatu, kuyesa kwa PCBA
Mayeso a PCBA atha kugawidwa mu mayeso a ICT, mayeso a FCT, mayeso okalamba, mayeso a vibration, etc.
Mayeso a PCBA ndiye mayeso akulu.Malinga ndi zinthu zosiyanasiyana komanso zofunikira zamakasitomala, njira zoyesera zomwe zimagwiritsidwa ntchito ndizosiyana.
Chachinayi, kusonkhana mankhwala anamaliza
The anayesedwa PCBA bolodi ndi anasonkhana kwa chipolopolo, ndiyeno kuyesedwa, ndipo potsiriza izo zikhoza kutumizidwa.
Kupanga kwa PCBA ndi ulalo umodzi pambuyo pa umzake.Vuto lirilonse mu ulalo uliwonse lidzakhala ndi zotsatira zazikulu kwambiri pa khalidwe lonse, ndipo kulamulira mwamphamvu kwa ndondomeko iliyonse kumafunika.
