Puas yog PCB ua tiav thaum qhov kev teeb tsa tiav thiab tsis pom muaj teeb meem nrog kev sib txuasthiab sib nrug?
Cov lus teb, tau kawg, tsis yog. Ntau tus pib, txawm tias suav nrog qee tus kws tshaj lij engineers, vim muaj lub sijhawm txwv lossis tsis siab ntev lossis tsis ntseeg siab,
zoo li yuav maj nrawm, tsis quav ntsej txog kev kuaj xyuas lig, muaj qee qhov kab mob qis heev, xws li kab dav tsis txaus, cov khoom siv daim ntawv lo luam ntawv
lub siab thiab qhov hluav taws xob qhov hluav taws xob tau kaw dhau lawm, cov teeb liab hauv lub voj voog, thiab lwm yam, ua rau muaj teeb meem hluav taws xob lossis cov txheej txheem, ua rau lub rooj tsavxwm loj, khib nyiab. Yog li ntawd,
Kev tshuaj xyuas tom qab yog ib kauj ruam tseem ceeb tom qab tau teeb tsa PCB.
1. Cov khoom ntim khoom
(1) Pad spacing. Yog tias nws yog ib lub cuab yeej tshiab, kos lawv tus kheej cov khoom siv pob, xyuas kom meej tias qhov sib nrug yog qhov tsim nyog. Pad spacing ncaj qha cuam tshuam rau vuam ntawm cov khoom.
(2) Ntawm qhov loj me (yog tias muaj). Rau cov khoom siv plug-in, qhov loj ntawm lub qhov yuav tsum tau khaws cia kom txaus cov paj, feem ntau tsis tsawg dua 0.2 hli yog qhov tsim nyog.
(3) Cov txheej txheem ntawm silk screen. Lub contour screen luam ntawv ntawm cov khoom yuav tsum yog
loj dua qhov loj npaum li cas los xyuas kom meej tias cov cuab yeej tuaj yeem ntsia tau zoo.
2. Kev teeb tsa
(1) IC yuav tsum tsis txhob nyob ze ntawm lub rooj tsavxwm.
(2) Lub Cheebtsam ntawm lub Circuit Court nyob rau hauv tib lub module yuav tsum tau muab tso rau ze rau ib leeg. Piv txwv li, lub decoupling capacitor yuav tsum yog
nyob ze rau lub hwj huam mov tus pin ntawm IC, thiab cov khoom uas tsim tib lub zog ua haujlwm yuav tsum tau muab tso rau hauv tib cheeb tsam nrog meej hierarchy.
los xyuas kom meej lub realization ntawm functions.
(3) Teem lub qhov (socket) qhov chaw raws li qhov tseeb installation. Lub qhov (socket) txuas nrog rau lwm cov modules los ntawm cov hlau lead, raws li qhov tseeb qauv,
txhawm rau txhim kho kom yooj yim, feem ntau siv qhov chaw nyob ze ntawm lub qhov (socket) txoj haujlwm, thiab feem ntau nyob ze ntawm board ntug.
(4) Ua tib zoo saib xyuas qhov hluav taws xob kev taw qhia. Lub qhov (socket) xav tau kev taw qhia, yog tias qhov kev taw qhia yog qhov sib txawv, cov hlau yuav tsum tau ua. Rau lub qhov (socket) tiaj tus, kev taw qhia ntawm lub qhov (socket) yuav tsum nyob rau sab nraud ntawm lub rooj tsavxwm.
(5) Yuav tsum tsis muaj cov khoom siv hauv qhov chaw khaws cia.
(6) Qhov chaw cuam tshuam yuav tsum nyob deb ntawm lub rhiab Circuit Court. Cov teeb liab ceev ceev, lub moos ceev lossis lub teeb liab hloov pauv tam sim no yog qhov cuam tshuam, yuav tsum nyob deb ntawm lub rhiab Circuit Court (xws li rov pib dua Circuit Court, analog circuit). Lawv tuaj yeem sib cais los ntawm ib qho hauv pem teb.
