Hauv Cov Lus Qhia no kuv yuav qhia koj yuav tsim thiab tsim koj li PCBs li cas, tshwj xeeb tshaj yog siv software dawb uas khiav ntawm Windows zoo li ntawm Mac.

Yam koj xav tau:

• computer nrog internet txuas
• cnc zeb/router, qhov tseeb dua qhov zoo dua
• 45 °/20 ° V-ntsis
• 0.8mm laum ntsis
• 3 hli endmill
• tooj liab clad board
• ob-sided nplaum daim kab xev

Kauj ruam 1: Tau txais Software

Koj xav tau cov software hauv qab no:

• Fritzing
• Inkscape
• Makercam

Nyem rau ntawm qhov txuas, rub tawm thiab teeb tsa software rau hauv koj lub computer. Makercam tsis xav tau rub tawm/teeb tsa txij li nws ua haujlwm ncaj qha hauv koj tus browser.

Kauj Ruam 2: Tsim hauv Fritzing

Pib Fritzing thiab pib kos duab tshiab.

Mus rau daim ntawv qhia zaub mov los ntawm txhaj rau ntawm daim ntawv qhia zaub mov tab nyob rau sab saum toj ntawm lub qhov rais.

Ntawm sab xis yog koj lub tsev qiv ntawv ib feem, xaiv cov khoom koj xav tau hauv koj lub voj voog thiab rub & tso rau hauv lub qhov rooj ci ci. Ua kom ntseeg tau tias cov khoom muaj qhov xav tau tshwj xeeb xws li pinout, tus nqi thiab qhov loj me. Koj tuaj yeem hloov cov kev hloov pauv no ntawm cov khoom xaiv hauv Tus Kws Saib Xyuas mus rau sab xis ntawm koj lub vijtsam.

Hauv qhov piv txwv no kuv tab tom ua ib qho Circuit Court uas siv Arduino Nano rau kev hloov pauv 12V. Rau qhov no kuv xav tau lub transistor nrog tus tiv thaiv rau lub hauv paus nrog rau kev ntes diode ua ke mus rau qhov txuas txuas thiab ob lub ntsia hlau txuas.

Kev sib txuas/xov hlau nruab nrab ntawm cov khoom siv tau ua los ntawm kev nyem thiab rub ntawm ob txhais ceg/tus pin ntawm cov khoom siv. Bendpoints hauv cov xov hlau tuaj yeem ua los ntawm kev nyem thiab rub sab hauv cov xov hlau.

Ua txhua qhov kev sib txuas uas koj xav tau thiab yuav ua rau ntawm daim ntawv qhia zaub mov kom lub Circuit Court ua haujlwm.

Kauj ruam 3: Schematic Saib

Tam sim no txav mus rau Schematic View.

Koj yuav pom daim duab kab hluav taws xob nrog rau tag nrho koj cov khoom siv thiab lawv cov kev sib txuas. Tidy cov khoom los ntawm kev rub cov khoom siv hauv qhov kev txiav txim tsim nyog thiab nyem thiab rub cov kab sib txuas sib txuas kom lawv tsis txhob cuam tshuam lawv tus kheej.

Kauj Ruam 4: PCB Saib

Mus rau PCB Saib.

Luag koj cov khoom hauv qhov kev txiav txim tsim nyog. Txoj cai zoo ntawm tus ntiv tes xoo yog tso cov khoom sib txuas nrog tus pin tshaj plaws rau hauv nruab nrab thiab lwm yam khoom nyob ib puag ncig. Sim kom tau txais kev faib me me.

Qhov xauv cia li kaw rau kab sib chaws koj pom hauv keeb kwm yav dhau. Txhawm rau hloov daim phiaj loj mus rau Saib -> Teeb daim phiaj loj.

Kauj ruam 5: Autoroute

Nyem rau Routing -> Autorouter/DRC teeb tsa thiab xaiv hom kev tsim khoom. Tam sim no koj tuaj yeem teeb tsa txoj kab dav rau qhov tuab uas xav tau nyob ntawm koj lub tshuab/qhov kawg/qhov Circuit. Kuv siv 48mil. Nyem "OK".

Xaiv cov duab plaub txho (lub Rooj Tswjhwm Saib PCB) thiab hauv Tus Kws Saib Xyuas hloov cov txheej txheej-tso rau "ib txheej (ib sab)".

Tam sim no tsoo Autoroute-khawm hauv qab ntawm lub qhov rais thiab cia lub khoos phis tawj ua txoj haujlwm ua haujlwm!

Kauj Ruam 6: Qee Qhov Ntxiv

Thaum Autorouting ua tiav, ua kom zoo ib yam los ntawm kev nyem thiab rub lawv cov ntawv khoov. Txoj cai nyem rau ntawm qhov chaw khoov thiab xaiv tshem tawm qhov khoov rau kom tshem nws.

Qee zaum muaj kev sib txuas Autorouter tsis tuaj yeem taug kev. Koj yuav tsum taug lawv los ntawm txhais tes los ntawm kev nyem thiab rub cov kab txuas sib txuas. Siv Jumpers los ntawm cov tsev qiv ntawv ib feem rau dhia hla cov kab uas koj txwv tsis pub yuav hla.

Koj tseem tuaj yeem ntxiv cov ntawv/lub cim uas yuav tshwm rau hauv daim npog tooj liab los ntawm kev rub "Silkscreen Image" lossis "Silkscreen Text" los ntawm lub tsev qiv ntawv rau koj pawg thawj coj. Xaiv koj lub logo thiab hauv Tus Kws Tshuaj Ntsuam Xyuas hauv qab Kev Tso Npe - pcb txheej cov ntawv qhia zaub mov nco tseg xaiv "tooj liab hauv qab". koj tuaj yeem thauj koj tus kheej.svg cov ntaub ntawv ib yam los ntawm txhaj rau "thauj cov duab" hauv tus kws tshuaj xyuas.

Kauj Ruam 7: Tshawb xyuas koj li Circuit Court

Yog tias koj xav tias koj tau npaj txhij nrog txoj kev nyem rau ntawm Routing -> Tsim Cov Cai Txheeb xyuas kom txiav txim siab koj li kev tsim rau kev sib txuas tsis sib xws / sib tshooj lossis cuam tshuam cov kab.

Sim tshem tawm txhua qhov ua yuam kev thiab rov ua DRC kom txog thaum tsis muaj teeb meem ntxiv. Tsim tiav lawm!

Export koj PCB li.svg cov ntaub ntawv los ntawm txhaj rau "Export rau PCB" hauv qab. Nyem rau ntawm tus xub me me ntawm lub pob Export thiab xaiv "Etchable (SVG)".

Koj yuav tau txais ib pawg ntawm svg qhov xa tawm hauv koj cov npe xaiv tab sis peb tsuas yog siv ob qho ntawm lawv:

• *yourfilename*_etch_copper_bottom_mirror.svg
• *yourfilename*_etch_mask_bottom_mirror.svg

Tag nrho lwm cov ntaub ntawv tuaj yeem raug tshem tawm.

Kauj ruam 8: Inkscape

Qhib *yourfilename *_etch_copper_bottom_mirror.svg hauv Inkscape, xaiv txhua yam thiab rov nias ctrl+ua haujlwm+g kom txog thaum txhua yam tsis koom nrog.
