Daim ntawv thov
Tam sim no, BGA thev naus laus zis tau siv dav hauv lub tshuab computer (portable computer, supercomputer, tub rog computer, telecommunication computer), kev sib txuas lus (pagers, portable phones, modems), automotive field (ntau yam controllers of automotive engines, automobile entertainment). .Nws yog siv nyob rau hauv ntau yam khoom siv passive, feem ntau yog cov arrays, networks thiab connectors.Nws cov ntawv thov tshwj xeeb suav nrog walkie-talkie, player, lub koob yees duab digital thiab PDA, thiab lwm yam.
FAQs
BGAs (Ball Grid Arrays) yog SMD Cheebtsam nrog kev sib txuas hauv qab ntawm cov khoom.Txhua tus pin yog muab nrog ib lub pob solder.Tag nrho cov kev sib txuas yog muab faib rau hauv ib qho kev sib txuas ntawm daim phiaj los yog matrix ntawm cov khoom.
BGA boards muaj kev sib tshuam ntau dua li PCBs ib txwm, tso cai rau siab ceev, me me PCBs.Txij li thaum cov pins nyob rau hauv qab ntawm lub rooj tsavxwm, cov txhuas leads kuj luv dua, yielding zoo conductivity thiab ceev ntawm cov cuab yeej.
BGA Cheebtsam muaj cov cuab yeej uas lawv yuav ua raws li tus kheej raws li cov solder liquifies thiab hardens uas pab nrog qhov chaw tsis zoo..Tom qab ntawd cov khoom siv yog rhuab los txuas cov hlau lead mus rau PCB.Lub mount tuaj yeem siv los tswj txoj haujlwm ntawm cov khoom yog tias soldering yog ua los ntawm tes.
BGA pob muajsiab dua tus pin ceev, qis thermal kuj, thiab qis inductancedua li lwm hom pob.Qhov no txhais tau hais tias kev sib txuas ntau dua pins thiab nce kev ua tau zoo ntawm kev kub ceev piv rau ob lub hauv kab lossis cov pob tiaj tus.BGA tsis yog tsis muaj nws qhov tsis zoo, txawm li cas los xij.
BGA ICs yognyuaj rau kev tshuaj xyuas vim yog cov pins zais hauv qab pob lossis lub cev ntawm IC.Yog li kev tshuaj xyuas qhov muag tsis tuaj yeem ua tau thiab de-soldering yog qhov nyuaj.BGA IC solder sib koom nrog PCB ncoo yog qhov ua rau muaj kev ntxhov siab thiab qaug zog uas yog tshwm sim los ntawm cov qauv cua sov hauv cov txheej txheem rov ua dua.
Lub neej yav tom ntej ntawm BGA Pob ntawm PCB
Vim yog vim li cas ntawm cov nqi ua tau zoo thiab ua haujlwm ntev, cov pob BGA yuav muaj ntau dua thiab nrov dua hauv cov khoom siv hluav taws xob thiab khoom siv hluav taws xob yav tom ntej.Tsis tas li ntawd, muaj ntau ntau hom pob BGA sib txawv tau tsim los ua kom tau raws li cov kev cai sib txawv hauv PCB industy, thiab muaj ntau qhov zoo los ntawm kev siv cov thev naus laus zis no, yog li peb tuaj yeem cia siab tias yuav muaj lub neej yav tom ntej zoo los ntawm kev siv BGA pob, yog tias koj muaj qhov yuav tsum tau, thov koj xav tiv tauj peb.
