Kodi Mawu Odziwika Odziwika Pakukonza kwa SMT Omwe Muyenera Kudziwa Ndi Chiyani? (I)

Pepala ili limatchula mawu odziwika bwino komanso mafotokozedwe amizere ya msonkhanomakina a SMT.
1. PCBA
Printed Circuit Board Assembly (PCBA) imatanthawuza njira yomwe ma board a PCB amakonzedwa ndikupangidwa, kuphatikiza mizere yosindikizidwa ya SMT, mapulagini a DIP, kuyesa magwiridwe antchito, ndi Msonkhano wazinthu zomalizidwa.
2. PCB bolodi
Printed Circuit Board (PCB) ndi nthawi yayifupi ya board board yosindikizidwa, yomwe nthawi zambiri imagawika m'magulu amodzi, gulu limodzi ndi gulu lamitundu yambiri.Zida zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo FR-4, resin, nsalu yagalasi ya fiber ndi gawo lapansi la aluminiyamu.
3. Gerber owona
Gerber wapamwamba makamaka limafotokoza Kutolere chikalata mtundu wa PCB fano (mzere wosanjikiza, solder kukana wosanjikiza, wosanjikiza khalidwe, etc.) pobowola ndi mphero deta, amene ayenera kuperekedwa kwa PCBA processing chomera pamene PCBA mawu wapangidwa.
4. BOM file
Fayilo ya BOM ndi mndandanda wazinthu.Zida zonse ntchito PCBA processing, kuphatikizapo kuchuluka kwa zipangizo ndi njira njira, ndi maziko ofunika zogula zinthu.Pamene PCBA imatchulidwa, iyeneranso kuperekedwa kwa PCBA processing plant.
5. SMT
SMT ndiye chidule cha "Surface Mounted Technology", chomwe chimatanthawuza njira yosindikizira phala, kuyika zigawo ndi ma sheet.reflow uvunikugulitsa pa bolodi la PCB.
6. Chosindikiza cha solder paste
Kusindikiza kwa solder phala ndi njira yoyika phala la solder pa ukonde wachitsulo, kutulutsa phala la solder kupyolera mu dzenje lachitsulo kupyolera muzitsulo, ndikusindikiza molondola phala la solder pa PCB pad.
7. SPI
SPI ndi chojambulira makulidwe a solder paste.Pambuyo posindikiza phala la solder, kuzindikira kwa SIP kumafunika kuti muwone momwe kusindikizira kwa solder phala ndikuwongolera kusindikiza kwa solder phala.
8. Reflow kuwotcherera
Reflow soldering ndikuyika PCB yoyikidwa mu makina a reflow solder, ndipo kupyolera mu kutentha kwakukulu mkati, phala la solder lidzatenthedwa kukhala madzi, ndipo pamapeto pake kuwotcherera kumatsirizidwa ndi kuzizira ndi kulimbitsa.
9. AOI
AOI imatanthawuza kuzindikira kwa maso.Kudzera kupanga sikani kuyerekeza, kuwotcherera zotsatira za bolodi PCB akhoza wapezeka, ndi zolakwika za PCB bolodi akhoza wapezeka.
10. Kukonza
Ntchito yokonza AOI kapena ma board omwe adadziwika pamanja.
11. DIP
DIP ndi yachidule ya "Dual In-line Package", yomwe imatanthawuza ukadaulo waukadaulo woyika zida zokhala ndi mapini mu bolodi la PCB, kenako ndikuzikonza kudzera pakuwotchera, kudula phazi, kugulitsa positi, ndi kutsuka mbale.
12. Wave soldering
Wave soldering ndi kuyika PCB mu ng'anjo yoweyula solder, pambuyo kutsitsi flux, preheating, wave soldering, kuzirala ndi maulalo ena kuti amalize kuwotcherera PCB bolodi.
13. Dulani zigawozo
Dulani zigawo pa bolodi welded PCB kukula koyenera.
14. Pambuyo kuwotcherera processing
Pambuyo kuwotcherera processing ndi kukonza kuwotcherera ndi kukonza PCB kuti si mokwanira welded pambuyo anayendera.
15. Kuchapira mbale
The kutsuka bolodi ndi kuyeretsa yotsalira zinthu zoipa monga flux pa yomalizidwa mankhwala PCBA kuti kukumana ndi chilengedwe chitetezo muyezo ukhondo chofunika makasitomala.
16. Kupopera mbewu kwa anti paint
Kupopera mbewu kwa anti penti kutatu ndikupopera utoto wapadera pa bolodi la mtengo wa PCBA.Ikachiza, imatha kusewera masewera otchinjiriza, kutsimikizira chinyezi, kutayikira, kutsimikizira kugwedezeka, kutsimikizira fumbi, umboni wa dzimbiri, umboni wokalamba, umboni wa mildew, magawo otayirira komanso kukana kwa corona.Ikhoza kuwonjezera nthawi yosungirako PCBA ndikupatula kukokoloka kwakunja ndi kuipitsidwa.
17. Mbale Wowotcherera
Kutembenuzidwa ndi PCB pamwamba yokulitsa mayendedwe am'deralo, palibe chivundikiro cha utoto wotchinjiriza, chomwe chingagwiritsidwe ntchito powotcherera zigawo.
18. Kufotokozera
Kupaka kumatanthawuza njira yopakira zigawo, kuyikako kumagawika kwambiri kukhala DIP iwiri - mzere ndi SMD patch ma CD awiri.
19. Kutalikirana kwa pini
Kutalikirana kwa mapini kumatanthauza mtunda wapakati pa mizere yapakati ya mapini oyandikana a gawo lokwera.
20. QFP
QFP ndi yachidule ya "Quad Flat Pack", yomwe imatanthawuza dera lophatikizika lopangidwa ndi pulasitiki lopyapyala lokhala ndi ma airfoil amfupi mbali zinayi.
