PCB multilayer board, raws li ib qho ntawm cov khoom tseem ceeb hauv kev lag luam hluav taws xob niaj hnub no, tau siv dav hauv ntau yam khoom siv hluav taws xob. Kev kos duab thiab tso tawm ntau txheej PCB boards yog ib txoj haujlwm tseem ceeb heev rau cov neeg tsim qauv.
1, Txhais tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab stacking kev txiav txim
Ua ntej, nws yuav tsum tau qhia meej tias thaum tsim PCB multilayer boards, peb yuav tsum xub qhia tus naj npawb tshwj xeeb ntawm cov khaubncaws sab nraud povtseg thiab stacking ib ntus ntawm cov boards multilayer. Raws li qhov yuav tsum tau ua ntawm peb tes num, peb kwv yees yuav tsum muaj pes tsawg txheej thiab qhia meej txog lawv txoj kev sib raug zoo nyob rau hauv cov txheej txheem stacking. Tom qab ntawd, raws li lub tswv yim no, peb pib kos thiab tsim.
2, Xav txog impedance tswj
Thaum tsim ntau txheej boards, peb kuj yuav tsum xav txog qhov teeb meem ntawm impedance tswj. Lub impedance ntawm cov khaubncaws sab nraud povtseg thiab pins sib txawv, thiab yog tias tsis tsim kom zoo, nws yuav ua rau kev ua haujlwm tsis zoo. Yog li ntawd, peb yuav tsum nkag siab txog cov hauv paus ntsiab lus ntawm kev tswj impedance thiab ua tib zoo xaiv cov boards tsim nyog thiab kab dav rau impedance tswj thaum kos duab los xyuas kom meej lub lag luam ntawm PCB multilayer boards.
3, Layout tsim yuav tsum tau ua tib zoo saib xyuas kom meej
Thaum tsim cov txheej txheem ntawm PCB multilayer boards, nws yog ib qho tsim nyog yuav tau xav txog kev sib raug zoo ntawm ntau qhov chaw ntawm lub rooj tsavxwm, pab pawg sib txawv, thiab tau txais qhov zoo tshaj plaws Circuit Court board architecture. Tsis tas li ntawd, layout tsim kuj yuav tsum tau xav txog cov teeb meem xws li qhov ntev thiab kev taw qhia ntawm txoj kev sib txuas kom txo tau lub sij hawm xaim hluav taws xob tsawg. Paub txog kev tsim lub rooj tsavxwm thiab siv nws txoj kev ua haujlwm tsis siv neeg tuaj yeem ua rau kev ua haujlwm zoo tshaj plaws.
4, Inter txheej rov siv dua thiab txo los ntawm qhov
Tsis tas li ntawd, txhawm rau txhim kho kev ua haujlwm ntawm PCB multilayer boards, peb tuaj yeem siv cov txheej txheem rov siv dua thiab txo cov txheej txheem los ntawm qhov. Tshwj xeeb, nws txhais tau hais tias sib tshooj ntawm cov kab ntawm cov txheej tooj liab, txheej teeb liab, thiab txheej txheej los txo qhov drilling thiab txo cov nqi tsim khoom. Tsis tas li ntawd, kev faib cov pins tsim nyog nyob rau hauv lub rooj tsav xwm hauv zos tuaj yeem txuag tau ntau qhov chaw thiab lub rooj tsavxwm, thiab txo cov nqi tsim khoom.
5, Siv cov khoom siv PCB zoo heev
Txhawm rau kom sai thiab ua tau zoo kos duab thiab teeb tsa PCB multilayer boards, peb yuav tsum siv cov khoom siv PCB siab heev.
