Ua ntej, cia peb nkag siab cov ntsiab lus thiab cov yam ntxwv ntawmPCB multilayerthiab ib txheej boards. Ib txheej board yog hom yooj yim tshaj plaws thiab yooj yim tshaj plaws ntawm PCB, uas tsuas yog muaj ib txheej ntawm cov hlau trajectory thiab ib txheej ntawm cov ntaub qhwv, haum rau kev tsim hluav taws xob yooj yim. Lub rooj tsavxwm ntau txheej yog tsim los ntawm stacking lub puab thiab txheej txheej, thiab cov teeb liab kis tau tus mob yog ua tiav ntawm lub puab thiab txheej txheej los ntawm interlayer kev sib txuas. Multilayer boards muaj kev sib koom ua ke siab thiab kev ua haujlwm zoo los tiv thaiv kev cuam tshuam, ua rau lawv tsim nyog rau kev tsim qauv hauv Circuit Court.
Tom ntej no, peb yuav sib piv PCB multilayer boards thiab ib txheej boards nyob rau hauv cov nram qab no yam.
1. Kev ua haujlwm hluav taws xob: PCB multilayer boards muaj kev ua haujlwm hluav taws xob zoo dua li cov boards ib txheej. Vim yog kev siv cov kab teeb liab sab hauv, ntau txheej boards tuaj yeem ua tiav txoj hauv kev luv luv ntawm kev sib kis thiab qis crosstalk, txhim kho teeb liab kev ntseeg tau thiab ruaj khov. Txawm li cas los xij, ib txheej ntawm cov boards raug cuam tshuam los ntawm kev cuam tshuam thiab hluav taws xob hluav taws xob vim tsis muaj cov teeb liab sab hauv.
2. Kev siv qhov chaw: PCB multilayer boards tuaj yeem ua tiav kev sib koom ua ke ntau dua thiab ua haujlwm ntau dua ntawm tib qhov loj. Nws tuaj yeem tsim cov kab hluav taws xob sib txawv nrog cov haujlwm sib txawv hauv cov khaubncaws sab nraud povtseg, txhim kho qhov chaw siv tau zoo. Txawm li cas los xij, cov boards ib txheej yog txwv los ntawm kev xaim thiab tsuas yog muab tso rau ntawm ib theem xwb, ua rau nws tsis tuaj yeem ua tiav kev sib koom ua ke siab.
3. Tus nqi tsim khoom: PCB multilayer boards muaj cov nqi tsim khoom ntau dua piv rau ib txheej boards. Thaum lub sij hawm tsim cov txheej txheem ntawm ntau txheej boards, yuav tsum tau ntxiv interlayer kev sib txuas thiab tooj liab plating, uas ua rau kom cov complexity thiab nqi ntawm kev tsim khoom, tshwj xeeb tshaj yog rau ntau txheej boards nrog ntau txheej. Kev tsim cov txheej txheem ntawm ib txheej boards kuj yooj yim thiab raug nqi.
4. Adaptation scenario: Xaiv hom PCB tsim nyog raws li qhov sib txawv ntawm daim ntawv thov scenarios. Rau cov qauv tsim qauv yooj yim, ib txheej txheej boards txaus kom tau raws li qhov yuav tsum tau ua thiab muaj nqi zoo. Rau cov qauv tsim hluav taws xob thiab cov xwm txheej uas yuav tsum tau muaj hluav taws xob ua haujlwm siab, ntau txheej boards yog qhov kev xaiv zoo dua.
