Khoom siv
Raws li ib tug neeg muag khoom ntawm ntau yam PCB technologies, ntim, txhuas lub sij hawm xaiv, peb muaj ib tug xaiv ntawm cov txheej txheem cov ntaub ntawv uas ib tug loj bandwidth ntawm ntau yam hom ntawm PCB yuav them thiab uas yeej ib txwm muaj nyob rau hauv tsev.
Cov kev xav tau rau lwm yam lossis rau cov ntaub ntawv tshwj xeeb kuj tuaj yeem ua tau raws li feem ntau, tab sis, nyob ntawm qhov xav tau tiag tiag, txog li 10 hnub ua haujlwm yuav xav tau kom tau txais cov khoom.
Hu rau peb thiab sib tham txog koj cov kev xav tau nrog ib qho ntawm peb pab neeg muag khoom lossis CAM.

stackup
Tus qauv 8 txheej PCB stackup yog 8 PCB pawg thawj coj saib.
Nws muaj cov txheej txheem sab nrauv thiab sab hauv thiab muaj ntau txheej txheej ntawm nws los tiv thaiv cov teeb liab crosstalk.
Cov txheej ntawm 8 txheej PCB stackup yog raws li nram no:
· Cov neeg ua si
· Silkscreenlayer
· Solder masklayer
· High-speed signallayer
· Teeb liab txheej
· Lub zog
· av txheej
Muaj 7 txheej ntawm dielectric uas txuas plaub lub dav hlau hauv av mus rau plaub txheej teeb liab.
