Kodi SPI Process ndi chiyani?

Kuwongolera kwa SMD ndi njira yoyesera yosapeŵeka, SPI (Solder Paste Inspection) ndi njira yopangira SMD ndi njira yoyesera, yomwe imagwiritsidwa ntchito kuzindikira mtundu wa solder phala yosindikiza yabwino kapena yoyipa.Chifukwa chiyani mukufunikira zida za spi mutatha kusindikiza phala la solder?Chifukwa deta kuchokera makampani za 60% ya soldering khalidwe ndi chifukwa osauka solder phala kusindikiza (zotsala zikhoza kukhala zokhudzana ndi chigamba, reflow ndondomeko).

SPI ndikuzindikira kusindikiza koyipa kwa solder,Makina a SMT SPIili kumbuyo kwa solder phala makina osindikizira, pamene solder phala pambuyo kusindikiza chidutswa cha pcb, kudzera kugwirizana kwa tebulo conveyor mu SPI zida kuyezetsa kuti azindikire ake ogwirizana kusindikiza khalidwe.

SPI imatha kuzindikira zovuta ziti?

1. Kaya phala la solder ndi malata

SPI akhoza kudziwa ngati solder phala kusindikiza makina osindikizira malata, ngati pcb ziyangoyango moyandikana ngakhale malata, izo mosavuta kutsogolera dera lalifupi.

2. Matani kuchotsera

Solder phala kuchotsera kumatanthauza kuti solder phala kusindikiza si kusindikizidwa pa pcb pads (kapena mbali chabe ya solder phala kusindikizidwa pa ziyangoyango), solder phala kusindikiza kuchotsera mwina kutsogolera soldering opanda kanthu kapena kuyimirira chipilala ndi zina osauka khalidwe.

3. Dziwani makulidwe a phala la solder

SPI imazindikira makulidwe a phala la solder, nthawi zina kuchuluka kwa phala la solder kumakhala kochulukirapo, nthawi zina kuchuluka kwa phala la solder kumakhala kochepa, izi zingayambitse kuwotcherera kapena kuwotcherera opanda kanthu.

4. Kuzindikira flatness wa solder phala

SPI amazindikira flatness wa solder phala, chifukwa solder phala makina osindikizira adzagwetsedwa pambuyo kusindikiza, ena adzaoneka kukoka nsonga, pamene flatness si nthawi yomweyo, n'zosavuta kuyambitsa mavuto kuwotcherera khalidwe.

Kodi SPI imazindikira bwanji mtundu wosindikiza?

SPI ndi chimodzi mwa zida kuwala chojambulira, komanso kudzera kuwala ndi makompyuta dongosolo aligorivimu kuti amalize mfundo kudziwika, solder phala kusindikiza, spi kudzera mkati kamera mandala pamwamba pa kamera kuchotsa deta, ndiyeno aligorivimu kuzindikira apanga. chithunzi kudziwika, ndiyeno ndi ok chitsanzo deta poyerekeza, poyerekeza ndi ok mpaka muyezo udzatsimikiziridwa ngati bolodi wabwino, poyerekeza ndi ok sichinaperekedwe alamu, amisiri akhoza kukhala Amisiri akhoza kuchotsa chilema mwachindunji matabwa ochokera ku lamba wotumizira

Chifukwa chiyani kuyendera kwa SPI kukuchulukirachulukira?

Tangotchulapo kuti mwayi kuwotcherera zoipa chifukwa solder phala kusindikiza chifukwa oposa 60%, ngati si pambuyo spi mayeso kudziwa zoipa, adzakhala mwachindunji kuseri kwa chigamba, reflow soldering ndondomeko, pamene akamaliza kuwotcherera ndiyeno pambuyo aoi. mayeso anapeza zoipa, pa dzanja limodzi, yokonza mlingo wa mavuto adzakhala woipa kuposa spi kudziwa nthawi ya vuto loipa (SPI chiweruzo cha kusindikiza zoipa, mwachindunji kuchokera conveyor lamba kutenga pansi, kuchapa phala) , Komano, pambuyo kuwotcherera, bolodi loipa lingagwiritsidwe ntchito kachiwiri, ndipo pambuyo pa kuwotcherera, katswiri akhoza kutsitsa mwachindunji bolodi loipa kuchokera pa lamba wonyamulira.Itha kugwiritsidwanso ntchito), kuwonjezera pa kukonza zowotcherera kungayambitse kuwononga kwambiri anthu, chuma ndi ndalama.
