Ntau tus tswvcuab ntawm no ntawm Kev Qhia Ntawv nug txog cov ntaub ntawv lossis tus pin tawm ntawm lub cuab yeej lossis tso tawm hauv cov lus teb, hmoov tsis koj tsis tuaj yeem ib txwm tau txais cov ntawv teev tseg thiab cov lej, hauv cov xwm txheej no koj tsuas muaj ib qho kev xaiv thim rov qab. Kev thim rov qab engineering yog qhov txuj ci uas tsis tau qhia hauv tsev kawm qib siab lossis tsev kawm qib siab cov khoom siv hluav taws xob thiab tseem yog nws yog cov cuab yeej muaj txiaj ntsig hauv tus kws tshaj lij cov cuab yeej siv. Coob leej neeg ua haujlwm ntawm cov khoom siv hluav taws xob tshawb nrhiav kom tsis muaj qhov kawg rau cov lej rau lub cuab yeej thaum lawv paub nws li cas hauv txhua qhov tshwm sim nws yuav siv sijhawm tsawg dua los ua lawv tus kheej cov lej thiab cov npe. Coj lub teeb nyem hauv lub Polaroid Lub Koob Yees Duab, yog tias koj xav ua qauv lub zog them hluav taws xob tom qab lub teeb nyem hauv lub koob yees duab no, tshwj tsis yog koj tau ua haujlwm rau Polaroid koj yuav muaj feem tau txais cov phiaj xwm nyob ib sab tsis yooj yim sua. Lwm yam dua li cov tshuaj tiv thaiv kev cai IC qhov seem ntawm lub Circuit Court tau yooj yim rau kab thiab ua cov phiaj xwm ntawm kev coj kuv tsuas yog plaub teev. Koj tuaj yeem txhais tes kos koj cov duab, tsim lawv hauv cov xim zoo li kuv ua, lossis tsim koj cov duab hluav taws xob sim hluav taws xob zoo ib yam li 123D Cov Hluav Taws Xob qhov twg lawv yooj yim nyeem thiab koj tuaj yeem sim lawv kom ntseeg tau tias koj ua cov phiaj xwm raug. Kuv tab tom yuav qhia koj qee yam uas koj xav paub kom thim rov qab engineer.

Kauj Ruam 1: Rov Qab Ua Haujlwm Engineering Surface Mount Device (SMD) Circuit Board

Txawm hais tias dhau los ntawm cov kab hluav taws xob Circuit Court thiab SMD cov laug cam zoo li sib txawv lawv ua haujlwm tib yam thiab lawv tau rov ua haujlwm tib yam. Los ntawm cov khoom sib dhos yog thawj ntu cov kws tsim txuj ci kawm paub nyeem, txawm li cas los cov cuab yeej siv saum npoo av, (SMDs) tsis yooj yim los nyeem vim yog qhov me me aria rau ib feem lossis cov lej xim. Txhawm rau txheeb xyuas cov khoom kom raug koj xav tau phau ntawv SMD thiab SMD cov lej Kuv tau ua cov no hauv hom PDF. SMD tus lej tiv thaiv tus lej yog tus lej ntawv txawm li cas los xij lawv tsis txawv dua li cov xim xim tiv thaiv, thawj tus lej yog thawj tus lej, tus lej thib ob yog tus lej thib ob, tus lej thib peb yog tus lej, thiab R yog tus lej zauv. Yog li 103 yog 10 kΩ thiab 4R7 yog 4.7 Ω yuav luag zoo li cov cai ntawm cov khoom siv hluav taws xob tsuas yog nrog cov capacitors tsab ntawv yog qhov ua siab ntev. SMD ICs muaj cov ntaub ntawv ntau ntxiv txog lawv xws li 74HC595 lossis HC595. Qhov dhau los ntawm lub cuab yeej yog SN74HC595 thiab feem ntau lub sijhawm cov ntaub ntawv khaws cia rau hauv lub qhov yuav ua qhov qub tab sis tsis yog txhua lub sijhawm. Txhawm rau kom tau txais cov ntaub ntawv qhia tseeb rau feem ntau SMD ICs siv tus lej lej ua ntej MM, yog li SN74HC595 yog MM74HC595 thiab koj tuaj yeem tau txais cov ntawv txheeb xyuas ntawm cov vev xaib no.https://www.maxim4u.com/https://www.alldatasheet.com / Rau SMD transistors thiab lwm cov semiconductors koj xav tau phau ntawv zoo ib yam hauv PDF hom ntawv ntawm no, ntawm cov semiconductor koj yuav pom tus lej zoo li 2X F. Thaum koj saib cov lej hauv phau ntawv chaws nws muab SMD tus lej MMBT4401 thiab dhau los ntawm qhov ntu tus lej 2N4401.

Kauj Ruam 2: Cov Txheej Txheem ntawm SMD Circuit Board

Tam sim no koj muaj qhov muaj nuj nqis thiab cov ntawv txheeb rau koj cov khoom koj tuaj yeem ua cov phiaj xwm ntawm pawg thawj coj saib xyuas. Rau ntu no qee zaum kuv tshem tawm cov khoom siv, thaij duab ntawm lub rooj tsavxwm, thiab taug qab cov neeg ua haujlwm hauv cov xim. Pib ntawm ib tus pin thiab ua raws tus neeg xyuas pib rau thawj qhov txuas kos tus pin thiab xaim thiab cov khoom siv yog tias tus neeg xyuas pib ceg tawm kos nws mus rau ntu ntxiv. Thaum koj tau kos tag nrho cov ceg ntawm tus neeg xyuas pib ntawd mus rau lwm sab ntawm thawj feem thiab kos tus neeg xyuas pib tom ntej thiab nws cov ceg ntoo mus rau cov khoom uas nws mus. Ua qhov no mus txog thaum koj tau kos cov phiaj xwm ntawm lub rooj tsav xwm hauv Circuit. Qhov Peb Peb capacitors 10 nf Ob-4 bar 103 yog ob-4 x 10 kΩ resistors Ob-4 bar 75R0 yog ob-4 x 75 Ω resistors Ob x 392 yog 3.9 kΩ resistors Ob x 51R1 rau 2 LEDs yog ob 51.1 Ω resistors Peb x 82R5 rau 3 LEDs yog peb 82.5 Ω resistors Plaub x 68R1 rau 4 LEDs yog plaub 68.1 Ω resistors Ib x 42A04F8, HC163 yog MM74HC163 lossis SN74HC163 IC Ob x 42A74HT, HC595 yog MM74HC595 lossis SN74HC595 IC Ob x 2X F yog MMBT440, lossis 2N4401 transistors Kingbright SA43-21GW SA43-13GW ib tus lej 7 ntu ntu LED zaub
