stack-up yog dab tsi?
Stack-up yog hais txog kev npaj ntawm cov txheej tooj liab thiab cov txheej txheem insulating uas ua rau PCB ua ntej board layout tsim.Thaum cov txheej txheej txheej tso cai rau koj kom tau txais ntau lub voj voog ntawm ib lub rooj tsavxwm los ntawm ntau cov txheej txheem PCB, cov qauv ntawm PCB stackup tsim muaj ntau yam zoo:
• Ib txheej txheej PCB tuaj yeem pab koj txo qis koj lub voj voog qhov tsis zoo rau cov suab nrov sab nraud nrog rau txo qis hluav taws xob thiab txo qis impedance thiab crosstalk kev txhawj xeeb ntawm kev kub ceev PCB layouts.
• Ib txheej zoo PCB pawg tuaj yeem pab koj sib npaug koj cov kev xav tau rau tus nqi qis, kev tsim khoom zoo nrog kev txhawj xeeb txog teeb meem kev ncaj ncees
• Txoj cai PCB txheej txheej tuaj yeem txhim kho Electromagnetic Compatibility ntawm koj tus qauv tsim thiab.
Nws feem ntau yuav yog rau koj cov txiaj ntsig los mus nrhiav ib qho kev teeb tsa PCB rau koj cov ntawv luam tawm Circuit Board-based applications.
Rau multilayer PCBs, cov txheej txheem dav dav suav nrog lub dav hlau hauv av (GND dav hlau), lub dav hlau fais fab (PWR dav hlau), thiab cov teeb liab sab hauv.Ntawm no yog ib qho piv txwv ntawm 8-txheej PCB stackup.
ANKE PCB muab multilayer / siab txheej Circuit Court boards nyob rau hauv thaj tsam ntawm 4 mus rau 32 txheej, board thickness ntawm 0.2mm mus rau 6.0mm, tooj liab thickness ntawm 18μm mus rau 210μm (0.5oz mus rau 6oz), puab txheej tooj liab thickness ntawm 18μm mus rau 70μm (0.5 oz rau 2oz), thiab qhov sib nrug tsawg kawg ntawm cov khaubncaws sab nraud povtseg rau 3mil.
