2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Txoj Haujlwm no yog xav tias peb twb tau ua tiav kev xaiv ua ntu zus. Rau lub kaw lus kom ua haujlwm tau zoo nws yog ib qho tseem ceeb kom nkag siab tias txhua qhov kev thov cuam tshuam li cas ntawm lub zog, qhov hluav taws xob, tam sim no, qhov chaw, cua txias thiab lwm yam. Kev vam khom xws li qib kev xav, suab nrov, kev cuam tshuam thiab lwm yam.

Ib qho tseem ceeb ntawm kev tsim qauv ntawm txoj haujlwm no yog PCB, vim peb lub hom phiaj yog txhawm rau txo daim ntawv foos ntawm cov kab hauv qab cov neeg hlau kom ntau li ntau tau uas ua rau txo qhov hnyav. Qhov me me thiab hnyav dua ua rau muaj txiaj ntsig zoo thiab tseem txo qhov poob vim muaj kev sib txhuam hauv lub cev. Yog tias koj pom lub tsheb sib tw F1 koj tuaj yeem nkag siab tias nws muaj txiaj ntsig zoo li cas hauv aerodynamics. Txhawm rau txhim kho kev ua haujlwm tau zoo thiab txo qhov hnyav, peb yuav tsum tshem tawm ib qho kev tiv thaiv uas tsis tsim nyog thiab txav mus rau Center of Mass kom tsawg li sai tau. Txhawm rau ua qhov no, kuv xav siv PCB li Chassis. Qhov no yuav txo qhov hnyav thiab ua rau CM qis dua, uas ua rau nce kev ruaj ntseg thaum tig mus. Ua lub chassis nrog PCB kuj tseem txo sijhawm siv rau kev sib dhos thiab ua kom yooj yim dua li peb tsuas yog yuav tsum tau muab cov khoom sib dhos tso rau ntawm qhov chaw raug thiab pib nrog kev sim software. Raws li PCBs yuav tsim los ntawm cov neeg hlau thiab CNC tshuab, nws zoo dua li lwm lub chassis.

Kauj ruam 1: Siv Software

Txog qhov haujlwm no, Kuv tau hais tshwj xeeb siv Freeware thiab Open Source Softwares kom cov tub ntxhais kawm thiab lwm tus neeg uas tsis muaj peev xwm nkag tau rau software tau tuaj yeem ua txoj haujlwm no tau zoo thiab muaj txuj ci.

Kuv siv KiCad rau Schematics thiab PCB Tsim thiab ntseeg kuv nws yog software zoo kawg. Ua ntej kuv tau siv Eagle CAD thiab Altium tab sis txawm tias KiCad tsis pub dawb nws muaj txhua lub peev xwm tseem ceeb thiab cov cuab yeej los tsim koj li PCB kev tshaj lij thiab tau txais nws tsim tawm. Txawm tias nws muaj 3D kev pom pom muaj rau koj li PCB.

KiCad suite muaj tsib ntu tseem ceeb:

• KiCad - tus thawj tswj hwm txoj haujlwm.
• Eeschema - tus txheej txheem ntes cov duab.
• Pcbnew - PCB txheej txheem txheej txheem. Nws tseem muaj qhov pom 3D.
• GerbView - tus saib Gerber.
• Bitmap2Component - cov cuab yeej hloov pauv cov duab mus rau hneev taw rau PCB kos duab.

Kuv yuav tsis qhia ntxaws yuav ua li cas thiaj tsim tau Schematic thiab PCB Layout vim qhov no tsis yog qhov nthuav ntawm cov ntawv/kab lus no. Qhov tseem ceeb tseem ceeb ntawm kab lus no yog los nthuav tawm cov txiaj ntsig ntawm KiCad thiab qhia seb nws tau xaj thiab tsim khoom li cas. Ua ntej peb pib nrog Schematic tsim nws tau qhia kom tsim cov phiaj xwm phiaj xwm thiab khaws txhua cov ntaub ntawv sab hauv. Hauv qab no yog ib qho piv txwv.

Kauj ruam 2: Schematic

Txog cov txheej txheem, peb yuav tsum qhib qhov Khoos Phis Tawj Cov cuab yeej los ntawm lossis Eeschema. Thaum qhib koj yuav tsum pom daim ntawv khoob hauv lub qhov rais zoo li hauv qab no.

Qee lub sij hawm peb xav tau los tsim Cov Cim Cim Tshiab raws li lub tsev qiv ntawv pib yuav tsis muaj lawv. Koj yuav tsum kawm cov ntawv teev npe rau cov khoom ntawd thiab ntxiv rau hauv lub tsev qiv ntawv tshwj xeeb raws li kuv tau ua hauv kuv rooj plaub. Kuv tsim lub tsev qiv ntawv cim rau QTR-8RC Sensor, OLED Display SSD1306, TB6612FNG Tsav Tsav Tsav Tsheb, N20 Lub Cev Tsav Tsheb nrog Encoders. Thaum tsim cov cim hauv lub tsev qiv ntawv kuv txuas nrog lawv ua ke los ua ib qho kab ke.

Koj tuaj yeem rub tawm Schematic los ntawm qhov txuas hauv qab no. Tom qab qhov kawg ntawm kev qhia, Kuv yuav ntxiv qee qhov kev qhia zoo rau KiCad rau koj kom kawm thiab ua nws ntawm koj tus kheej.

Kauj Ruam 3: PCB Txheej Txheem

Thaum Schematic ua tiav nws yog lub sijhawm txav mus rau txheej txheej PCB pawg thawj coj. Qee lub sij hawm koj kuj yuav tsum tsim hneev taw ntawm qee yam khoom siv yog tias lawv tsis nyob hauv lub tsev qiv ntawv. Txhawm rau tsim hneev taw koj tuaj yeem siv Footprint Library Editor Tool hauv KiCad.

Kuv tau siv ob txheej tsim ntawm no vim tias nws ua rau nws yooj yim rau txheej thaum koj muaj ntau yam khoom faib rau ntawm lub rooj tsavxwm. Txhawm rau pib nrog PCB Tsim peb yuav tsum qhib PCB txheej txheem txheej txheem txheej txheem hauv KiCad. Koj yuav tsum pom qee yam zoo li hauv qab no tab sis nrog daim ntawv khoob hauv nws.

Peb yuav Siv NextPCBas PCB Kev Pabcuam Kev Tsim Khoom yog li nws yog qhov tseem ceeb kom pom dab tsi yog yam tsawg kawg nkaus thiab qhov siab tshaj plaws kev txwv uas lawv muaj rau lawv kev tsim khoom. Txhawm rau txheeb xyuas tias peb yuav tsum tau mus ntsib lawv Cov Peev Xwm Nplooj Ntawv. Qhov tsis tseem ceeb uas peb yuav tsum txheeb xyuas yog:

• Max. Dimension 510*590 hli
• Min. Kab 4mil / 0.1 hli
• Min. Kab nrug 4mil / 0.1mm
• Min. qhov loj 0.3mm
• Min. Ntawm txoj kab uas hla 0.45mm
• Via Rau Kab Laug Spacing ≥5mil
• Laum Qhov Loj 0.2-6.3mm
• Taug qab mus rau Tus Qauv ≥0.4mm

Raws li Cov Ntsiab Lus saum toj no peb yuav tsum hloov kho peb Cov Cai Tsim hauv KiCad Layout Editor.

Thaum kawg ntawm qhov kev qhia, kuv yuav txuas qee qhov kev qhia zoo txog PCB Tsim Qauv hauv KiCad uas koj tuaj yeem kawm los ntawm. Hauv qab no yog qhov txuas PCB tsim uas koj tuaj yeem siv rau koj qhov kev siv.

Kauj Ruam 4: Kev Tsim PCB

Ua ntej peb tsim PCB hauv PCB Fabrication House / Industry likeNextPCB, peb yuav tsum hloov peb cov qauv tsim rau hauv cov qauv tsim khoom uas tuaj yeem nyeem tau los ntawm cov cav tov ntawm kev lag luam.

Cov teeb tsa saum toj no tau siv rau tiam ntawm txhua cov ntaub ntawv Gerber. nws tau qhia tias koj xa cov ntaub ntawv hauv cais Gerber nplaub tshev raws li kuv tau ua.

Cov Ntaub Ntawv hais txog qhov ntawm PCB tau muab khaws cia rau hauv cais cov ntawv Drill thiab tsim kom tau tias kuv tau siv cov teeb tsa saum toj no rau NextPCB. Lwm cov tuam txhab tsim khoom tuaj yeem muaj teeb tsa sib txawv. Nws muaj ntau qhov laj thawj los xaiv NextPCBone ntawm qhov laj thawj yog lawv qhov kev pom zoo txog lawv cov txheej txheem tsim khoom. Hauv qab no yog qee cov duab los ntawm lawv lub Hoobkas.

Lawv kuj lees txais ntau yam kev xaiv them nqi: PayPal, Hloov Chaw Them Nyiaj, Western Union, Them Nyiaj Ntawm HQ. For Txoj Kev Xa Khoom, lawv muaj DHL, FedEx, Hongkong Post uas yooj yim nrog tus nqi sib txawv thiab txiaj ntsig. Rau cov txheej txheem ntawm kev xaj khoom, peb yuav tsum tsim tus as khauj hauv lub vev xaib. Koj tuaj yeem siv qhov txuas rau npe thiab tsim tus as khauj tshiab. tom qab tsim tus account koj yuav pom qee yam zoo li hauv qab no.

Kauj Ruam Tom ntej yog Tshaj Tawm Koj Cov Ntaub Ntawv Gerber thiab tso qhov kev txiav txim kom ua tiav los pib tsim khoom. Thaum koj Gerber tau tsim nws tau pom zoo kom zip lawv ua ke hauv ib daim ntawv thiab xa lawv

Thaum qhov upload tiav koj tuaj yeem pom qhov kev txiav txim hauv koj tus account nplooj ntawv.

Koj daim ntawv xaj yuav tshuaj xyuas kom raug thiab ib zaug nws tau npaj rau kev tsim khoom lawv yuav thov kom them nyiaj thiab thaum them nyiaj raug tshem tawm qhov kev tsim khoom yuav pib.

Lawv siv sijhawm zoo los txheeb xyuas koj li Gerber Cov ntaub ntawv vim nws yuav muaj qhov ua yuam kev thiab yuav tsis tsim khoom zoo yog tias lub qhov me me dhau lossis muaj lwm qhov kev tsim yuam kev hauv nws.

Thaum PCB raug txheeb xyuas thiab tsim tau lawm koj yuav tau txais PCB hauv ob peb hnub thiab npaj ua haujlwm rau nws.

Txog qhov tau txais tshwj xeeb NTAWV QHIA LINK: NextPCB thiab koj tuaj yeem tau txais 10% tawm rau PCB thiab PCB kev sib sau ua ke (Kev Txheeb Xyuas Ua Haujlwm: Mar 26, 2020 - Plaub Hlis 30, 2020)

Ua tsaug rau koj nyeem kab ntawv no vam tias nws yuav pab koj. Tsis txhob hnov qab tshawb xyuas lwm cov kab lus hauv kab ntawv no.
