Nrog modem lub neej thiab kev hloov pauv thev naus laus zis, thaum tib neeg raug nug txog lawv qhov kev xav tau ntev ntev ntawm cov khoom siv hluav taws xob, lawv tsis yig los teb cov lus tseem ceeb hauv qab no: me dua, sib dua, nrawm dua, ua haujlwm ntau dua.Txhawm rau hloov kho cov khoom siv hluav taws xob niaj hnub no rau cov kev xav tau no, cov tshuab luam ntawv qib siab tshaj plaws hauv Circuit Board sib dhos tshuab tau nthuav dav thiab siv tau, ntawm cov tshuab PoP (Package on Package) tau txais ntau lab tus neeg txhawb nqa.
Pob ntawm Pob
Pob ntawm Pob yog cov txheej txheem ntawm stacking Cheebtsam lossis ICs (Integrated Circuits) ntawm lub motherboard.Raws li txoj kev ntim khoom siab heev, PoP tso cai rau kev sib koom ua ke ntawm ntau lub ICs rau hauv ib lub pob, nrog cov logic thiab nco nyob rau hauv cov pob saum toj thiab hauv qab, ua kom ceev ceev thiab kev ua tau zoo thiab txo qhov chaw mounting.PoP tuaj yeem muab faib ua ob hom: qauv qauv thiab TMV qauv.Cov qauv txheej txheem muaj cov khoom siv logic hauv qab pob thiab cov khoom siv nco lossis cov cim xeeb hauv cov pob saum toj kawg nkaus.Raws li kev hloov kho tshiab ntawm PoP tus qauv qauv, TMV (Los ntawm Mould Via) qauv paub txog kev sib txuas sab hauv ntawm cov cuab yeej logic thiab lub cim xeeb los ntawm cov pwm los ntawm lub qhov ntawm cov pob hauv qab.
Pob-on-pob suav nrog ob lub thev naus laus zis tseem ceeb: pre-stacked PoP thiab on-board stacked PoP.Qhov sib txawv tseem ceeb ntawm lawv yog tus naj npawb ntawm reflows: lub qub dhau los ntawm ob reflows, thaum lub tom kawg dhau los ntawm ib zaug.
Qhov zoo ntawm POP
PoP thev naus laus zis tau siv dav los ntawm OEMs vim nws qhov txiaj ntsig zoo:
• Flexibility - Stacking qauv ntawm PoP muab OEMs xws li ntau yam kev xaiv ntawm stacking uas lawv tuaj yeem hloov kho cov haujlwm ntawm lawv cov khoom yooj yim.
• Txo qhov loj me
• Txo tus nqi tag nrho
• Txo cov motherboard nyuaj
• Txhim kho kev tswj xyuas logistics
• Txhim kho qib kev siv thev naus laus zis
