Dab tsi yog cov khoom siv feem ntau siv rauHDI PCB pawg thawj coj saib?
Cov txheej txheem stacked yog ib qho tseem ceeb cuam tshuam rau EMC kev ua tau zoo ntawm PCB boards thiab tseem yog ib qho tseem ceeb ntawm kev tiv thaiv electromagnetic cuam tshuam. Nrog kev tshwm sim tsis tu ncua ntawm high-speed circuits, qhov nyuaj ntawm PCB boards kuj nce. Txhawm rau kom tsis txhob muaj hluav taws xob cuam tshuam, cov teeb liab txheej thiab lub zog txheej yuav tsum tau sib cais, yog li nws suav nrog HDI PCB board stacking tsim. Yog li, dab tsi yog qhov feem ntau siv stacking qauv rau HDI PCB boards?
1. Yooj Yim Ib Txheej Txheej Luam Ntawv Circuit Board
Tsim 6 txheej ntawm cov laug cam ib zaug, nrog cov txheej txheem stacking ntawm (1+4+1). Hom vaj huam sib luag no yog qhov yooj yim tshaj plaws, uas yog, tsis muaj qhov faus rau hauv ntau txheej txheej ntawm lub vaj huam sib luag, thiab nws tuaj yeem ua tiav hauv ib qho xovxwm. Tsis zoo li ntau txheej boards, ntau yam txheej txheem xws li laser drilling qhov muag tsis pom qhov yuav tsum tau ua yav tom ntej.
2. Pa HDI luam ntawv board nrog ib zaug stacking
Ib txheej ntawm HDI 6- txheej board, nrog ib txheej txheej ntawm (1+4+1). Cov qauv ntawm cov vaj huam sib luag no yog (1+N+1), (N Ntau dua lossis sib npaug rau 2, N txawm), uas yog tam sim no tus qauv tsim ntawm laminated boards hauv kev lag luam. Sab hauv ntau txheej boards muaj faus qhov thiab yuav tsum tau nias theem nrab kom tiav.
3. HDI luam ntawv boards rau cov pa theem nrab stacking
Secondary stacking HDI 8- txheej board, nrog ib tug stacking qauv ntawm (1++1+4+1+1). Cov qauv ntawm cov vaj huam sib luag no yog (1+1+N+1+1), (N Ntau dua lossis sib npaug rau 2, N txawm), uas yog tam sim no tus qauv tsim ntawm theem nrab stacking hauv kev lag luam. Lub vaj huam sib luag sab hauv muaj faus qhov thiab xav tau peb lub xovxwm kom tiav.
4. Hom thib ob ntawm cov pa theem ob txheej HDI luam ntawv board
Secondary stacking HDI 8- txheej board, nrog ib tug stacking qauv ntawm (1+1+4+1+1). Cov qauv ntawm lub rooj tsavxwm no (1+1+N+1+1), (N Ntau dua lossis sib npaug rau 2, N txawm tias), txawm hais tias nws yog cov qauv laminated thib ob, vim qhov chaw ntawm qhov faus qhov tsis nyob nruab nrab ntawm (3-6) cov khaubncaws sab nraud povtseg, tab sis nruab nrab ntawm (2-7) cov khaubncaws sab nraud povtseg, qhov tsim no yuav txo tau cov txheej txheem nias los ntawm ib lub sij hawm, yog li ntawd lub HDI board ntawm lub thib ob laminated board xav tau peb txheej txheem nias, thiab yog optimized kom muaj ob txheej txheem nias.
5. HDI ntawm Secondary Stacking rau qhov muag tsis pom qhov Stacking tsim
Cov qhov muag tsis pom kev yog stacked saum lub qhov faus (2-7) txheej, thiab HDI 8- txheej phaj yog stacked ob zaug, tsim ib tug qauv ntawm (1+1+4+1+1). Cov qauv ntawm cov phaj no yog (1+1+N+1+1), (N Ntau dua lossis sib npaug rau 2, N txawm), nrog ntau txheej txheej ntawm daim hlau nrog cov qhov faus uas yuav tsum tau ua kom tiav cov txheej txheem thib ob.
6. Hla txheej qhov muag tsis pom qhov tsim rau HDI ntawm ob txheej txheej
Secondary stacking HDI 8- txheej board, nrog ib tug stacking qauv ntawm (1+1+4+1+1). Cov qauv ntawm cov vaj huam sib luag hom no yog (1+1+N+1+1), (N Ntau dua lossis sib npaug rau 2, N txawm), uas yog lub vaj huam sib luag laminated nrog qee qhov teeb meem hauv kev lag luam tsim khoom. Sab hauv ntau txheej ntawm lub vaj huam sib luag tau faus qhov hauv (3-6) txheej thiab xav tau peb lub xovxwm kom tiav.
7. Kev ua kom zoo ntawm HDI panels nrog rau lwm cov txheej txheem stacked
Triple txheej luam boards los yog PCB boards nrog ntau tshaj peb txheej kuj yuav optimized. Ua tiav HDI board nrog peb txheej yuav tsum tau plaub laminations.
