1. Lub ncoo tsim yuav tsum muaj peev xwm ua tau raws li qhov yuav tsum tau muaj ntawm qhov ntev, dav thiab qhov sib nrug ntawm lub hom phiaj ntaus tus pin.
Kev saib xyuas tshwj xeeb yuav tsum tau them rau: qhov kev ua yuam kev me me uas tsim los ntawm lub cuab yeej tus pin nws tus kheej yuav tsum raug coj mus rau hauv tus account hauv kev tsim - tshwj xeeb tshaj yog cov khoom siv meej thiab cov ncauj lus kom ntxaws thiab cov khoom sib txuas.
Txwv tsis pub, nws yuav ua rau muaj kev sib txawv ntawm cov khoom siv tib yam, qee zaum cov khoom siv vuam vuam yog siab, qee zaum cov teeb meem loj ntau lawm tshwm sim!
Yog li ntawd, kev sib raug zoo tsim ntawm lub ncoo (tsim nyog thiab feem ntau rau cov tuam txhab loj feem ntau 'cov ntaub ntawv loj tsim) yog qhov tseem ceeb heev!
Hais txog qhov no, cov kev cai yooj yim tshaj plaws thiab kev tshuaj xyuas yog:
Muab lub hom phiaj ntaus ntawv tso rau ntawm lub ncoo ntawm PCB pawg thawj coj saib xyuas, yog tias txhua tus pin ntawm lub cuab yeej nyob hauv thaj tsam sib thooj.
Lub pob tsim ntawm lub ncoo no yeej tsis yog qhov teeb meem loj.Hloov pauv, yog tias qee tus pins tsis nyob hauv lub ncoo, nws tsis zoo.
2. Lub ncoo tsim yuav tsum muaj ib qho kev taw qhia pom tseeb, zoo dua yog ib qho universal thiab yooj yim distinguishable kev taw qhia polarity cim.Txwv tsis pub, thaum tsis muaj cov qauv PCBA tsim nyog rau kev siv, yog tias tus neeg thib peb (SMT Hoobkas lossis tus kheej outsourcing) ua cov txheej txheem vuam, nws yuav ua rau rov qab polarity thiab vuam tsis raug!
3. Cov ntaub ntawv tsim los yuav tsum muaj peev xwm ua tau raws li cov txheej txheem ua, cov kev xav tau thiab kev ua haujlwm zoo ntawm cov khoom siv PCB Circuit Court nws tus kheej.
Piv txwv li, lub ncoo kab loj, kab sib nrug, cim ntev thiab dav uas tuaj yeem tsim tau, thiab lwm yam. Yog tias PCB loj loj, nws raug nquahu kom koj tsim raws li cov txheej txheem PCB nrov thiab ntau yam hauv khw, yog li ntawd. thaum tus neeg muag khoom PCB raug hloov pauv vim muaj teeb meem kev koom tes hauv kev lag luam, muaj ob peb PCB cov tuam txhab xaiv los ntawm thiab cov sijhawm tsim khoom tau qeeb.
