Ib lub vaj huam sib luag
Ntawm feem ntau cov PCB tseem ceeb tshaj plaws, feem yog concentrated ntawm ib sab, thaum cov xov hlau muaj cov hlau muaj sab tod. Vim tias cov xov hlau tsuas tshwm ntawm ib sab, hom PCB no hu ua ib tog. Vim tias muaj ntau txoj kev txwv nruj rau kev tsim ntawm ib lub vaj huam sib luag ntawm ib sab thiab yuav tsum tau ua raws li kev sib cais), tsuas yog siv sijhawm thaum ntxov siv hom board no.
Ob Chav Board
Hom ntawm Circuit Court muaj xaim ntawm ob sab, tab sis siv cov xov hlau ntawm ob sab, tsim nyog Circuit Court kev sib txuas yuav tsum tau ua nruab nrab ntawm lawv. Tus "choj" ntawm cov kab ncig no yog hu ua ib qho ntawm. Ib qho dhau los - lub qhov yog lub qhov me me uas tau sau lossis siv cov hlau ntawm tus PCB, uas tuaj yeem txuas nrog cov xov hlau ntawm ob sab. Vim tias thaj tsam ntawm ob npaug {4 {{eded vaj huam sib luag yog ob npaug ntawm cov khoom siv sib luag), ua rau nws siv ntau dua rau kev siv ntau dua li lub vaj huam sib luag.
Ntau - txheej board
Txhawm rau nce thaj chaw uas tuaj yeem tsim tawm, ntau - txheej cov nus siv ntau dua lossis ob npaug {1} eded wiring cov laug cam. Cov ntawv luam tawm hluav taws xob nrog ib ob npaug {3} {{{{{{{{{{{{}} txheej} txheej txheej printered Circuit Coad. Cov ntawv luam tawm Circuit Court yog kev sib txuas lus los ntawm txoj haujlwm ua haujlwm thiab rwb thaiv tsev cov ntaub ntawv sib thooj, thiab cov qauv coj los tsim raws li qhov yuav tsum tau ua. Tus naj npawb ntawm cov khaubncaws hauv paus ntawm cov khaubncaws hauv paus ntawm ib lub rooj tsavxwm tsis yog txhais tau tias muaj ntau txoj hauv kev ywj pheej. Hauv cov xwm txheej tshwj xeeb, txheej txheej me yuav raug ntxiv los tswj cov board tuab. Feem ntau, tus naj npawb ntawm txheej yog txawm thiab suav nrog otertermost ob txheej. Feem ntau cov motherboard muaj cov qauv ntawm 4 txog 8 txheej, tab sis technically, nws yog qhov ua tau ua kom tiav tus pcb board nrog ze li 100 txheej. Feem ntau cov neeg ua haujlwm loj tshaj plaws siv ob peb txheej ntawm Motersboards, tab sis vim tias cov koos pij tawj muaj ntau cov khoos phis tawj muaj ntau yam tsis tau siv. Vim tias txhua txheej hauv PCB yog qhov tseem ceeb ua ke, nws feem ntau tsis yooj yim pom tus lej tiag, tab sis yog tias koj ua tib zoo saib lub motherboard, koj tseem tuaj yeem qhia.
