BGA PB. fakatahaʻanga

BGA PCB ko e ngaahi papa ʻoku paaki ʻaki e grid ʻo e foʻi pulu. ʻOku mau fakaʻaongaʻi ha ngaahi founga kehekehe ki hono ngaohi ʻo e BGA PCBs. Ko e faʻahinga PCBs pehee ʻoku siʻisiʻi hono lahi, totongi maʻamaʻa, mo e density maʻolunga. Ko ia, ʻoku nau falalaʻanga ki hono fakaʻaongaʻi ʻo e ngaahi ngāue ʻoku māʻolungá.

Ngaahi Lelei ʻo e BGA PCB

1. Fakaʻaongaʻi Totonu ʻo e Feituʻú
ʻOku fakaʻata kitautolu ʻe hono fokotuʻutuʻu ʻo e BGA PCB ke tau fakaʻaongaʻi lelei ʻa e feituʻu ʻoku ʻataa. Ko ia, te tau lava ʻo fakapipiki ha ngaahi konga lahi ange mo ha ngaahi meʻangaue maʻamaʻa ange.
2. Fakaʻofoʻofa e Ngāue Vela mo Fakaʻuhilá
ʻOku siʻisiʻi ʻaupito ʻa e lahi ʻo e ngaue tokoni ʻa e BGA PCB. Ko ia, ʻoku faingofua ange ʻa e ʻea vela dissipation. ʻOku ʻikai kato ʻa e faʻahinga PCB ko ʻeni. Ko ia, ʻoku ʻikai ha fakatuʻutāmaki ia ke maumauʻi pe piko ai. Ko ia, ʻoku tuʻu maʻu feʻunga ʻa e PCB ke fakapapauʻi ʻoku fakaʻofoʻofa e ngaue fakaʻuhila.
3. ʻOmi ʻe he ngaohiʻanga koloa maʻolunga ange
ʻOku siʻisiʻi ange ʻa e sipinga BGA PCB lahi taha koeʻuhi ke vave ange ʻenau faʻu. Ko ia, ʻoku tau maʻu ha koloa maʻolunga ange pea toe faingamalie ange ʻa e founga.
4. Siʻisiʻi Ange ʻa e Maumau ke Fakaiku
ʻOku tau fakaʻaongaʻi ha ngaahi foʻi pulu solder fefeka ki hono ngaohi ʻo e ngaohiʻanga BGA. Ko ia, ʻoku ʻi ai ha tuʻunga fakatuʻutamaki siʻisiʻi ange te nau maumauʻi lolotonga e tafa.
5. Totongi Maʻulalo Ange
ʻOku fakapapauʻi ʻe he lahi siʻisiʻi ange mo e halanga ngaohiʻanga koloa ʻoku tau fakatupu maʻulalo ange ʻa e fakamole ki he ngaohiʻanga koloa. Ko ia, ʻoku feʻunga ʻa e founga ko ʻení ki ha tulama lahi.

BGA PCB ngaohiʻanga koloa

  • ʻOku tau ʻuluaki fakamafanaʻi ʻa e fakatahaʻanga fakalukufua.
  • ʻOku tau fakaʻaongaʻi solder ngaahi foʻi pulu ʻoku fuʻu puleʻi ʻaupito solder. Koeʻuhi ke tau lava ʻo fakaʻaongaʻi soldering ki hono fakamafanaʻi kinautolu.
  • Ko ia ʻoku hanga ʻe he solder ʻo vaia.
  • ʻOku cools hifo ʻa e solder pea ʻoku ne fakahehema ke fakamalohia.
  • Ka neongo ia, ʻoku fakatupu ʻe he vavakovi ʻa e solder haka ke fenapasi lelei mo e fakaʻapaʻapa ki he papa ʻo e ngaahi vahaʻa taimi.
  • Neongo ʻoku mahuʻinga ke fili fakalelei ʻa e fokotuʻutuʻu ʻo e solder alloy mo e mafana soldering.
  • ʻOku tupu ʻeni he kuo pau ke tau fakapapauʻi ʻoku ʻikai vaia ʻaupito ʻa e solder. Ko ia, ʻoku tuʻu maʻu.
  • Ko ia, ʻoku kei fakamavaheʻi pe ʻa e foʻi pulu takitaha mei he ngaahi foʻi pulu hoko mai.

Faʻahinga ʻo e BGA PCBs

1. PBGA (Fokotuʻutuʻu ʻo e grid fuopotopoto pelesitiki)
Ko ia, ʻoku fakaʻaongaʻi ʻe he ngaahi meʻa ni ʻa e pelesitiki ko ha naunau mo ha ipu sioʻata ʻoku fakamilemila.
2. TBGA (Fokotuʻutuʻu ʻo e grid ʻo e Tepi fuopotopoto)
Ko ia, ʻoku fakaʻaongaʻi ʻe he ngaahi meʻá ni ha faʻahinga fengāueʻaki ʻe ua. ʻOku makatuʻunga ʻa e ngaahi fehokotaki ko ʻeni ʻi he taki mo e tokotolu solder fetuʻutaki.
3. FBGA (Taila maka e grid ʻo e foʻi pulu)
Ko ia, ʻoku fakaʻaongaʻi ʻe he ngaahi meʻa ni ha taila maka fakavahaʻa-taʻu ko e naunau substrate.

Sivi ʻo e BGA PCB

ʻOku tau fakaʻaongaʻi lahi taha ʻa e sivi X-Lei ki hono vakavakaiʻi e ngaahi fotunga ʻo BGA PCBs. ʻOku ʻiloa ʻa e founga ko ʻeni ko xRD ʻi he ngaueʻanga pea fakafalala ki he X-huelo ke tatala ʻa e ngaahi fotunga pulipulia ʻo e PCB ko ʻeni. ʻOku fakaha mai ʻe he faʻahinga sivi ko ʻeni,
1. Solder tuʻunga fakataha
2. Solder fakataha ofi
3. Liliu ʻi he fotunga fuopotopoto
4. Solder kaunga ngaue matolu

BGA PCBs mei he tekinolosia MOKO

  • 1-50 kuta
  • Falanise-4, CEM-1, CEM-3, Hight TG
  • HALS/HALS taki taʻetotongi
  • 0.2MM-7mm Board matolu
  • 500MM×500mm naʻe ʻosi boar ʻa Meki

Ko e tekinolosia MOKO ko ha hingoa ʻiloa ia ʻi he ngaahi ngaueʻanga PCB. ʻOku ʻi ai haʻatau fokotuʻutuʻu ki he ngaohiʻanga koloa fakaʻosi mo ha timi ʻo ha kau mataotao feʻunga ʻaupito. ʻOku tau tokanga taha ki he fakatahaʻanga BGA PCB pea te tau lava ʻo faʻu customized papa ʻo hange ko hoʻo ngaahi fie maʻu. Ongoʻi tauʻatāina ke tokoniʻi kimautolu ʻi hono fokotuʻu hoʻomou māú he ʻahó ni.
