Nyob zoo sawv daws, Qhov no yog kev qhia yog hais txog "Yuav ua li cas thiaj ua PCB hauv Tsev" yam tsis muaj cov khoom siv tshwj xeeb. Nws yog cov tub ntxhais kawm siv tshuab hluav taws xob, Kuv sim ua DIY cov haujlwm uas xav tau cov khoom siv hluav taws xob yooj yim thiab ua PCBs.

PCB yog dab tsi?

Ib daim ntawv luam tawm Circuit Board (PCB) kev txhawb nqa tshuab thiab txuas hluav taws xob txuas nrog cov khoom siv hluav taws xob siv cov khoom siv hluav taws xob, cov ntaub qhwv thiab lwm yam khoom siv ntxiv los ntawm cov ntawv tooj liab laminated mus rau cov txheej txheem tsis ua haujlwm.

Lub rooj tsav xwm luam tawm tau npaj ua ntej ua cov tooj tooj liab ntawm daim ntawv coj ua. Cov kab lus ua ntej tau txiav txim siab txo cov kab thaiv uas ua rau txo qhov ua yuam kev tshwm sim vim tsis muaj kev sib txuas. Ib tus xav tau yooj yim tso cov khoom sib txuas ntawm PCB thiab muab tshuaj txhuam rau lawv.

Txoj kev sib txawv los ua PCB

Muaj nyob hauv txhua peb txoj hauv kev los ua PCB1. Hlau ntawm Glossy ntawv txheej txheem

2. Circuit los ntawm txhais tes ntawm PCB

3. Laser txiav ntug etching.

Txij li cov txheej txheem laser yog cov txheej txheem tsim los ua PCB peb yuav tau nthuav dav ntawm thawj ob txoj hauv kev los ua PCB hauv tsev.

Kauj Ruam 1: Tsim PCB Txheej Txheem ntawm Koj Lub Vaj Tsev

Qhov no feem ntau ua tiav los ntawm kev hloov pauv koj daim duab qhia chaw rau hauv PCB txheej txheem siv PCB txheej txheem software. Ntau muaj ntau qhov qhib qhov software pob rau PCB teeb tsa tsim thiab tsim qauv.

1. Cadsoft Dav dawb hau

2. PCBWizard

Kuv tsim kuv cov phiaj xwm hluav taws xob hauv Cadsoft Eagle.

Nco tseg: Hauv Dav Dav Dav: Cov Ntaub Ntawv> Export> Duab Nco ntsoov teeb DPIG rau 1200 kom zoo dua qub

Kauj Ruam 2: Cov Khoom Yuav Tsum Tau

Koj kuj tseem xav tau: tus cim xim dub ruaj khov, rab riam txiav, ntawv xuab zeb, ntawv hauv chav ua noj, ntaub paj rwb, qee yam khaub ncaws qub. Txhawm rau pib ua PCB, xav txog txoj haujlwm yooj yim KOV SWITCH siv IC555

Kauj Ruam 3: Siv Luam Tawm ntawm PCB Layout

Luam tawm ntawm koj li PCB txheej txheem siv lub tshuab luam ntawv laser thiab daim ntawv A4 duab/ntawv ci. Nco ntsoov cov ntsiab lus hauv qab no:

Koj yuav tsum nqa daim iav luam tawm

Xaiv cov zis hauv dub ob qho tib si los ntawm PCB tsim software thiab teeb tsa lub tshuab luam ntawv

Nco ntsoov tias cov ntawv luam tawm tau ua rau sab ci ntawm daim ntawv

Kauj Ruam 4: Txiav Tooj Phaj

Txiav tooj liab tooj liab raws li qhov loj ntawm kev teeb tsa.

Kauj Ruam 5: Ua Kom Zoo

Rub sab tooj liab ntawm PCB siv cov ntaub plaub plaub lossis txhuam txhuam txhuam. Qhov no tshem tawm txheej txheej txheej sab saum toj ntawm tooj liab nrog rau daim duab tiv thaiv txheej.

Sanded nto tso duab kom lo zoo dua

Kauj Ruam 6: Txoj Kev

Txoj Kev 1:

Hlau ntawm Glossy ntawv txheej txheem: Hloov cov duab luam tawm los ntawm daim ntawv yees duab mus rau lub rooj tsavxwm. Nco ntsoov tig sab saum toj kab rov tav. Muab cov tooj liab saum npoo ntawm lub rooj tsavxwm tso rau ntawm qhov chaw luam tawm. Ua kom ntseeg tau tias pawg thawj coj tau ua kom raug raws cov ciam teb ntawm cov ntawv luam tawm. Muab daim kab xev raws ob sab ntawm lub rooj tsavxwm uas tsis yog tooj liab. Qhov no yuav pab tuav lub rooj tsavxwm thiab cov txheej txheem luam tawm hauv txoj haujlwm.

Txoj Kev 2:

Circuit los ntawm kev siv tus cim cim tas mus li: Siv cov duab hauv kab ntawv luam tawm ntawm daim ntawv ci ua ntej kos cov duab kos yooj yim ntawm cov phaj tooj liab nrog xaum thiab tom qab ntawd los ntawm tus cim dub tas mus li.

Kauj ruam 7: Hlau nws

Tom qab luam tawm ntawm cov ntawv ci peb hlau nws daim duab sab rau sab tooj. Ua kom sov Cov Hluav Taws Xob Hluav Taws Xob kom sov tshaj plaws

Muab lub rooj tsavxwm thiab daim ntawv yees duab tso rau ntawm lub rooj ntoo huv thiab khaub ncaws nrog sab nraub qaum ntawm daim duab thaij duab ntsib koj

Tuav ib qho kawg ntawm Towel thiab muab cov hlau kub tso rau lwm qhov kawg li 10 vib nas this. Tam sim no, hlau daim ntawv yees duab tag nrho nrog siv cov lus qhia thiab siv lub zog me me txog li 5 txog 15 feeb

Ua tib zoo saib rau ntawm ntug ntawm lub rooj tsavxwm - koj yuav tsum tau siv lub siab, ua kom lub ntsej muag maj mam

Xovxwm ntev zoo li ua haujlwm zoo dua li txav hlau ncig

Ntawm no cov cua sov ua kom yaj cov kua luam tawm ntawm cov ntawv ci thiab hloov mus rau phaj tooj liab

CEEV FAJ: Tsis txhob kov ncaj qha phaj tooj liab vim nws kub heev vim yog hlau

Kauj ruam 8: Tev tawm

Tom qab ironing, tso daim ntawv luam tawm hauv Lukas dej sov li ntawm 10 feeb. Ntawv yuav yaj thiab tshem daim ntawv maj mam muab. Tshem daim ntawv tawm ntawm lub kaum sab xis & kab zauv.

Qee qhov xwm txheej thaum tshem daim ntawv qee qhov kev taug tau tsaus muag.

Saib daim duab hauv lub thawv dawb kab kab dub kab khiav yog lub teeb pom kev zoo li no peb tuaj yeem siv tus cim dub mus rau qhov pom kev tsaus nti raws li qhia hauv duab

Kauj ruam 9: Etching

Koj yuav tsum tau ceev faj heev & ceev faj thaum ua cov kauj ruam no • Ua ntej muab cov hnab looj tes yas los yas. • Muab qee cov ntawv xov xwm xwv kom cov kua nplaum ua kom tsis puas hauv av. 1) Siv lub thawv yas thiab sau nws nrog dej. 2) Dissolve 2-3 rab diav ntawm ferric chloride fais fab hauv dej. 3) Muab PCB los rau hauv Etching solution (Ferric chloride solution, Fecl3) rau kwv yees li 30 feeb. 4) Fecl3 reacts nrog cov tooj liab uas tsis pom thiab tshem tawm cov tooj liab uas tsis xav tau los ntawm PCB.5) Cov txheej txheem no hu ua Etching. Siv cov cuab yeej tshem tawm PCB thiab tshawb xyuas yog tias tag nrho thaj tsam uas tsis muaj qhov muag tau raug kos los yog tsis. Nyob rau hauv rooj plaub nws tsis raug tshem tawm nws rau qee lub sijhawm ntxiv hauv kev daws teeb meem. Maj mam txav lub thawv yas mus thiab mus kom cov tshuaj daws teeb meem cuam tshuam nrog tooj liab thiab tsim cov hlau thiab tooj liab chloride. Tom qab txhua txhua 2-3 feeb xyuas seb puas muaj tooj liab sib xyaw los tsis yog.

Kauj ruam 10: Ceev faj

TSIS TXHOB TIV THAIV KOOB TSEV KAWM NTAWV SOLUTION Siv GLOVES Hauv daim duab peb tuaj yeem pom tias tooj liab tau maj mam muab pov tseg.

Kauj ruam 11: Pov tseg

Kev daws teeb meem yog tshuaj lom rau ntses thiab lwm yam dej muaj sia.

Tsis txhob ncuav nws rau hauv lub dab dej thaum koj ua tiav. Nws tsis raug cai ua li ntawd thiab yuav ua rau koj cov kav dej puas.

Dilute etching tov thiab tom qab ntawd muab cov tshuaj pov tseg.

Kauj Ruam 12: Kov Kawg

Daim duab qhia PCB ntawm ob lub Circuit Court ua los ntawm kev luam tawm thiab siv tus cim.

Ob peb tee ntawm thinner (tshem cov ntsia thawv polish ua haujlwm tau zoo) ntawm qhov me me ntawm cov paj rwb yuav tshem tawm cov tshuaj toner, nqa rov qab cov tooj liab rov qab. Yaug kom zoo thiab qhuav nrog daim ntaub huv lossis ntawv ua zaub mov noj. sandpaper. Acetone pab cov ntawv ci lo rau daim ntawv ntxhib.

Laum qhov thiab txhuam tag nrho cov khoom siv & PCB tau npaj tiav. Cheer !!

Kauj Ruam 13: Xaus

1. Iron on Glossy paper method yog txoj hauv kev zoo los ua pcb hauv tsev. Yog ua tib zoo ua txhua txoj kab tuaj yeem luam tau zoo kawg nkaus.

2. Circuit los ntawm txhais tes ntawm PCB yog txwv rau peb cov txuj ci txuj ci txuj ci. Txoj kev yooj yim tuaj yeem ua tau yooj yim los ntawm txoj kev no tab sis rau cov pcb nyuaj Hlau ntawm Cov ntawv ci yog qhov zoo tshaj plaws.
