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

Rau kuv qhov khoom siv hluav taws xob tshiab kawg kuv tau txiav txim siab los ua lub thawv hloov pauv hloov pauv, tsuas yog siv lwm qhov perf-board kuv txiav txim siab ua pcb rau nws yog li kuv tuaj yeem sau cov txheej txheem thiab ua kom qhia tau. Kuv txiav txim siab ua qhov no vim tias kuv tseem tsis tau pom leej twg ua nws ntawm Instructables yog li kuv xav tias nws yuav yog qhov zoo los qhia. Cov txheej txheem no ua haujlwm tau zoo rau cov kab hluav taws xob yooj yim uas tsis muaj ntau txoj kab npav me me nyob hauv lawv, Kuv tau ua ob peb lub guitar ntaus lub thawv no ib yam nkaus.

Kauj ruam 1: Cov ntaub ntawv

Cov ntaub ntawv los tsim thiab Kos lub rooj tsavxwm:

-Paper thiab Pencil -Ruler-Sharpee-Xev-Scissors -Tiny #65 twist ntsis (0.035 uas yog qhov zoo rau feem ntau cov khoom siv hluav taws xob) -Dremal lossis pin vise rau qhov tho qhov, Dremal yog qhov pom tseeb yeej ntawm no-Copper clad PC boardMaterials Cuam Tshuam Ferric Chloride yog cov kua ua kua ntau heev ua rau cov hlau ua xeb, yog li ntawd ib tus yuav tsum tau ua txhua yam kev tiv thaiv kev tiv thaiv kom tiv thaiv koj tus kheej vim nws ua rau zoo Yog li ntawd koj kuj tseem xav tau-Cov Hnab Roj Hmab-Kev Nyab Xeeb Kev Ruaj Ntseg-Ntawv phuam kom ntxuav qhov nchuav -Qhov chaw ua haujlwm muaj cua zoo li cov pa ua pa kuj tsis zoo thiab tsis zoo rau ua pa. koj xav tau, -Cov thawv ntim yas me me tuaj yeem tso FC rau hauv rau etching thiab khaws cia tom qab. ua FC.

Kauj Ruam 2: Tsim Tus Qauv Circuit

Siv ntawv thiab xaum xim tsim cov txheej txheem ntawm Circuit Court, nws yog qhov yooj yim tshaj plaws los ua qhov no yog saib sab saum toj ntawm lub rooj tsavxwm, nws tseem pab kom muaj tag nrho cov khoom sib txawv ntawm tes los pab sib nrug thiab tso chaw. Raws li cov lus ceeb toom tseem nco ntsoov tsim cov txheej txheem kom nws zoo haum rau ntawm lub rooj tsavxwm. Yog tias koj twb muaj cov qauv tsim ua ntej koj tuaj yeem hla qhov no.

Nov yog qhov kuv teeb tsa zoo li rau lub thawv hloov pauv resistor.

Kauj ruam 3: Drilling Board

-Tom ntej no koj xav tau zoo los theej ib daim qauv ntawm kev tsim uas yog qhov thim rov qab ntawm qhov qub, yog tias koj kos nws thim rov qab lossis ib qho uas koj muaj twb tau thim rov qab tsuas yog ua daim ntawv tsis tu ncua.

-Cut the copy of the layout out with scissors leave some of both side so you can fold it around the PCB and tape it in place. -Tam sim no siv daim kab xev, kaw qhov tsim rau sab tooj liab ntawm PCB. Kuv tus kheej nyob ntawm lwm sab vim tias kuv tsis tau thab plaub kom thim rov qab nws. -Tus #65 laum me ntsis siv qhov txheej txheem txhawm rau txhawm rau lub qhov nyob hauv nruab nrab ntawm txhua daim ntaub nplaum rau ib tus zuj zus. Kuv nyiam teeb tsa lub rooj tsavxwm hla ib yam dab tsi los txhawm rau txhawm rau ua kom cov hmoov av fiberglass me me tsim los ntawm qhov kev khawb, qhov no yog iav tais me me.

Kauj Ruam 4: Teeb Duab

-Thaum koj tau laum tag nrho lub qhov tshem tawm daim qauv tsim los ntawm PCB thiab ntxuav tag nrho cov hmoov av.

-Kev siv Sharpie kos daim kab laug sab nyob ib puag ncig txhua lub qhov uas koj nqus, pab kom muaj tus cwj mem tshiab nrog lub ntsiab lus ntse rau qhov no, nco ntsoov tias tus cwj mem tawm ntawm kab ntawv zoo ua ntej lwm yam nws zoo tsis tawm tsam FC ib yam. -Tam sim no siv daim ntawv thim rov qab ntawm cov txheej txheem raws li siv qhov kos hauv txhua qhov cim nrog Sharpie, yog tias koj ua yuam kev koj tuaj yeem siv alcahol ntawm me ntsis ntawm cov ntawv phuam kom tshem tawm qhov ua yuam kev. -Koj tseem tuaj yeem siv Sharpie ntxiv cov ntawv rau pawg thawj coj saib rau kev sib txuas lossis ib qho twg. -Yog koj tsis tau ua li ntawd lawm, txiav koj lub rooj tsavxwm tawm ntawm seem PCB cov khoom seem.

Kauj ruam 5: Etching

-Pib tawm los ntawm kev nrhiav qhov chaw huv huv uas koj tuaj yeem nyab xeeb teeb tsa lub rooj tsav xwm kev nyab xeeb, nyiam dua sab nraud.

-Hnav cov hnab looj tes thiab tsom iav kev nyab xeeb. -Nco ntsoov tias koj tso koj lub hnab looj tes thiab tsom iav kev nyab xeeb, Ferric Chloride yog cov khoom phem. Nqa koj lub ntim me me thiab hliv li 1/4 "txog 1/2" ntawm Ferric Chloride rau hauv. -Tau lub thawv loj dua nrog dej sov txog 1 "tob. FC txav mus uas pab nrog txheej txheem kos duab. -Txawm li 5-7 feeb koj yuav tsum pib pom cov tooj liab pib ploj mus, ceeb toom rau thaj chaw uas cov kab kos tau kos tsis cuam tshuam dab tsi. ua kom tiav tag, thaum lub sijhawm twg koj yuav tsum tshem tawm PCB sai thiab tso nws mus rau hauv cov dej hauv lub thawv loj kom yaug nws thiab tom qab ntawd so nws tawm ntawm daim ntawv so tes. tuaj yeem siv Ferric Chloride ntau dua ob peb zaug, thiab nchuav cov dej hauv lub khob loj dua thiab yaug tawm.

Kauj Ruam 6: Ntxuav PCB

-Kev siv 0000 Cov ntaub plaub hlau ntxuav lub Sharpie tawm ntawm kab.

-Txhua lub rooj tsavxwm nrog cov khoom siv.
