Muaj ntau lub sijhawm thaum peb, uas yog tus tsim khoom, ntsib teeb meem xws li kev nyuaj hauv Circuit Court, teeb meem kev txuas xov tooj thiab cov phiaj xwm tsis raug thaum siv cov laug cam tsim qauv. Txij li txhua qhov haujlwm zoo yuav tsum ua kom huv thiab huv si yog tias nws yog lub hom phiaj ua qauv qhia. Yog li txhawm rau tshem tawm cov teeb meem tau hais los saum no, peb pib nrhiav lwm txoj hauv kev. Kom meej meej, peb muaj lub tswv yim tias PCBs yog txoj hauv kev mus tab sis tseem, rau qee tus ntawm peb, muaj cov cuab yeej txwv thiab peb xav tias nws ua tsis tau. Tab sis ntseeg kuv, nws yog!

Cov lus qhia no tsom mus rau kev taw qhia tus nyeem ntawv kom ua nws tus kheej PCB siv txoj kev kho Toner Transfer method. Muaj ntau cov ntaub ntawv qhia thiab cov vev xaib tawm yuav tsum npog yuav ua li cas thiaj ua PCBs hauv tsev pheej yig, thiab kuv ib yam tau ua raws lawv, tab sis tseem muaj qee qhov txuj ci thiab hacks uas ib tus txhim kho nrog lub sijhawm thiab kev paub thiab cov lus qhia no npog li cas kuv ua kuv li PCBs.

Kuv tsis nyiam tshaj tawm cov ntsiab lus uas twb muaj nyob hauv is taws nem, tab sis lub sijhawm no kuv yuav tsum, vim tias feem ntau ntawm kuv cov phiaj xwm cuam tshuam nrog kev cai PCBs thiab kuv tsis xav khaws sau PCB cov txheej txheem tsim hauv lawv ntau thiab ntau dua hauv tag nrho kuv cov ntawv qhia. Kuv kuj xav kom ntxaws cov txheej txheem me ntsis ntxiv thiab yog li ntawm no peb yog.

Qhov ntawd yog txhua yam kuv tau hais txog qhov kev qhia no. Yog li, yam tsis muaj ado ntxiv, cia pib nrog qhov no!

Kauj Ruam 1: Sau ib puag ncig qee yam khoom

Cov khoom uas koj yuav xav tau rau kev ua PCB feem ntau yog kho vajtse thiab cov cuab yeej tsim khoom. Lawv tsis yog pheej yig heev lossis tsis kim thiab yooj yim los ntawm.

Qhov Yuav Tsum Tau:

Copper Clad Board

Thaum yuav qhov no, nco ntsoov yuav lub rooj tsav tsheb tsis muaj roj, uas yuav tsum muaj yuav luag tsis muaj qhov ntsuab ntawm lub rooj tsavxwm.

Ferric Chloride Etching Tshuaj

Qhov no yog qhov kev daws teeb meem uas yuav siv los hloov tooj liab rau hauv cov khoom sib txuas uas tsis yog cov khoom siv.

Drilling Tshuab

Nws yog nyob ntawm koj seb koj puas siv lub tshuab ua kom puv puv ntau dua li tuav tes me. Kuv siv lub tshuab siv tes tuav kuv tus kheej. Nov yog yuav ua li cas ua koj tus kheej.

• Tus Cwj Pwm Cuam Tshuam
• Zero Qib Sanding Paper
• Luam tawm txheej txheem

Luam tawm ntawm lub voj voog uas koj yuav ua. Nco ntsoov tias daim ntawv uas yuav tsum luam tawm no yuav tsum yog qhov ci, cov ntawv zoo li ntawv hauv cov ntawv xov xwm uas muaj kev ntxhib los mos. Kuj xyuas kom nws tau siv lub tshuab luam ntawv laser.

Khaub Ncaws Hlau

Qhov ntawd yog txhua yam rau qhov xav tau. Ua mus ntxiv rau theem tom ntej.

Kauj Ruam 2: Npaj Lub Rooj Tooj Liab Tooj

Cov tooj liab clad board uas koj muaj yog nws nquag dhau.

Passivity yog txheej txheem tsim cov txheej txheej oxide los tiv thaiv kev xeb.

Hauv ib qho tooj liab clad board, muaj tooj liab uas yog hlau tsis zoo, thiab yog li los ntawm cov lus txhais saum toj no, nws, los ntawm nws tus kheej, tsim ib txheej ntawm Copper Oxide thaum twg los txog rau hauv huab cua los tiv thaiv kev xeb. Txij li tooj liab oxide yog qhov ua tau zoo, nws yuav ua teeb meem hauv peb PCB. Yog li peb thawj txoj haujlwm yog tshem tawm cov txheej no.

Tshem Tawm Cov Tooj Oxide Txheej:

Xaiv cov ntawv xoom xoom thiab pib txhuam daim txiag tooj liab kom txog thaum koj tuaj yeem pom cov lus ci xim hlau.

Koj tuaj yeem pom qhov sib txawv ntawm cov xuab zeb thiab cov xuab zeb tsis nyob hauv daim duab saum toj no.

Txiav Board:

Tam sim no uas peb tau tshem tawm cov txheej tooj liab oxide, cia peb txiav daim ntawv tooj liab raws li cov ntawv luam tawm. Sim kom muaj thaj chaw khaws cia ntxiv nyob ze ntawm ciam teb kom tso cai txiav qhov yuam kev.

Txhawm rau txiav lub rooj tsavxwm, Kuv siv kuv rab riam txiab thiab qee zaum kuv rab riam thermocol. Yog tias koj muaj lub ntsej muag pom, tom qab ntawd siv nws vim nws yog txoj hauv kev zoo tshaj plaws los txiav cov laug cam.

Kauj Ruam 3: Hloov Toner

Hauv cov kauj ruam no, peb yuav xa cov laser toner los ntawm cov ntawv luam tawm mus rau tooj liab clad board.

Txhawm rau hloov lub toner:

1. Khaws koj cov khaub ncaws hlau.
2. Teem nws mus rau qhov kub tshaj plaws thiab tua lub qhov cub.
3. Nqa koj li tooj liab pawg thawj coj thiab teeb tsa thiab muab cov txheej txheem tso rau ntawm lub rooj tsavxwm xws li cov toner ntawm cov ntawv luam tawm yuav tsum muaj kev sib cuag nrog tooj liab sab ntawm lub rooj tsavxwm.
4. Ua kom sov tag nrho cov teeb tsa los ntawm sab nraub qaum ntawm daim ntawv rau 2 feeb siv cov khaub ncaws hlau nrog ntau qhov siab. Khaws txav ib ncig ntawm cov hlau nyob rau hauv ib puag ncig puag ncig lub rooj tsavxwm kom ntseeg tau tias muaj kev hloov pauv.
5. Thaum koj xav tias tag nrho cov toner tau raug xa mus rau ntawm lub rooj tsavxwm, nres qhov ironing.
6. Muab lub lauj kaub kub tso rau hauv dej da dej tam sim.
7. Tom qab ob peb feeb, khaws nws thiab maj mam muab txhuam tawm ntawm txhua daim ntawv kom koj tsuas muaj cov tshuaj toner rau ntawm lub rooj tsavxwm raws li qhia hauv daim duab saum toj no.

Tam sim no lub toner tau ua tiav tiav. Yog tias koj pom qee qhov cim tsis tiav, tsis tas yuav ntshai. Koj tuaj yeem ua tiav lawv tau yooj yim siv koj tus cim ruaj khov.

Txawm li cas los xij yog tias ntau lub toner tsis tau xa mus tau zoo, rov ua cov txheej txheem los ntawm kev txhuam cov toner thiab rov hloov nws. Nws coj kuv ob zaug los ua qhov no. Daim duab sim tsis tau ua tiav tau suav nrog saum toj no.

Kauj ruam 4: Etching lub Rooj Tswjhwm Saib

Tam sim no peb lub rooj tsavxwm tau muab txua nrog tus qauv. Nws zoo li ib feem ntawm cov cai sab laug kom ua tiav. Yog li txhawm rau ua kom nws ze dua rau PCB tiav peb yuav tau kos nws siv cov tshuaj daws teeb meem. Kuv yuav siv Ferric Chloride vim nws yooj yim rau kuv.

Peb yuav tau kos peb lub rooj tsavxwm kom tsuas yog siv cov tooj liab uas muaj txiaj ntsig raws li kev coj ua. Lub ntsiab lus tseem ceeb ntawm kev kos yog qhov hloov pauv ib puag ncig thaj tsam ntawm tooj liab mus rau hauv cov nag, hauv kuv cov ntaub ntawv nws yog tooj liab chloride, thiab tshem nws nrog rau kev daws teeb meem tom qab cov tshuaj tiv thaiv tiav.

Ib feem ntawm cov txiaj ntsig tau khaws cia los ntawm kev tawm tsam los ntawm kev zais nws nrog toner. Nov yog txhua yam uas tshwm sim nyob ntawm no.

Txhawm rau kos lub rooj tsavxwm:

Ncuav qee cov tshuaj ferric chloride rau hauv lub thawv uas tsis yog xim hlau

Ferric Chloride muaj qhov ua xeb nyob rau hauv qhov xwm txheej yog li kuv xav kom txhua tus tsis txhob siv cov thawv ntim hlau vim nws cuam tshuam nrog cov ntim. Siv cov thawv yas yog qhov kev xaiv zoo. Kuj tiv thaiv ib qho kev sib cuag ntawm koj cov tawv nqaij nrog cov lus no. Hloov chaw, nyiam hnav hnab looj tes thoob plaws txheej txheem.

Muab koj daim ntawv tooj liab tso rau hauv thiab tso nws tseg rau qee lub sijhawm

Hauv kuv qhov xwm txheej, tag nrho cov txheej txheem kos duab tau siv li 45 feeb.

Saib xyuas koj lub rooj tsav xwm hauv ntu 15 feeb thiab xaiv nws thaum koj xav tias nws tau raug tshem tawm tag

Txoj kev kuv sim yog tias lub rooj tsav tooj liab tau muab txhuam los yog tsis yog los ntawm kev saib seb nws zoo li ib nrab txhais tau tias tsis yog. Txawm li cas los xij PCB uas kuv muaj lub sijhawm no zoo heev. Ntawm qhov kos, nws tig daj.

Tam sim no koj li PCB tau ua tiav ua tiav, cia tshem tawm cov tshuaj toner uas seem kom tau txais peb cov ntawv luam tawm Circuit Board.

Kauj Ruam 5: Tshem Tawm Cov Toner seem

Tam sim no peb PCB yuav luag tiav. Txhua yam uas tau ua dhau los yog tshem tawm cov tshuaj toner kom pom cov tooj liab. Yog li cia peb tau txais nws.

Txhawm rau tshem tawm cov toner uas seem:

EITHER

Xuab zeb tag nrho PCB siv cov ntawv xuab zeb xoom

LOS YOG

Siv cov acetone-dipped paj rwb bale, ntxuav tag nrho lub rooj tsavxwm kom huv

Kuv tau pom tias kev siv acetone rau kev tshem tawm cov toner yog qhov zoo dua yog tias koj xav kom koj lub PCB kom huv thiab huv. Tab sis nws tsis txhais tau hais tias txoj kev sanding tsis sawv ntsug, vim tias nws tsis zoo li cov xuab zeb tsis huv. Nws cia li tawm ob peb khawb.

Kauj Ruam 6: Drilling

PCB tau ua tiav, cov tooj liab muaj nyob tab sis qhov twg los ntxig rau cov khoom? Txhawm rau txhawm rau ntxig rau peb cov khoom, peb yuav tau pib qhov qhov rau lawv.

Siv txhua yam kev xyaum uas koj nyiam rau lub hom phiaj no.

Tsuas yog cov lus qhia uas kuv xav muab rau cov pib tshiab yog thaum siv lub tshuab drilling, ua ntej tso lub laum me ntsis perpendicularly hla rau qhov yuav tsum tau laum qhov chaw thiab tom qab ntawd ua kom lub zog nyob ib ntus thaum ua haujlwm me me ntawm qhov siab. Qhov no tiv thaiv lub ntsis ntsis ntsis los ntawm straying tawm thiab ua tau zoo drilled qhov.

Kauj Ruam 7: Txhim Kho Cov Cim

Hauv qee kis, cov cim ntawm PCB yog nqaim. Nov yog rooj plaub rau feem ntau SMD PCBs. Hauv cov xwm txheej zoo li no, muaj kev pheej hmoo ntawm xaim hlau tawg tawm ntawm lub rooj tsavxwm vim ntau dhau thaum siv lub sijhawm ntev. Txhawm rau tiv thaiv qhov no, yam kuv, thiab ntau lwm tus ua, yog siv cov tshuaj txhuam ntawm cov kab, cov txheej txheem no hu ua tinning.

Ua tsaug rau sergeweb1 rau taw qhia tias txheej txheem no lub hom phiaj tseem ceeb yog txhawm rau tiv thaiv kev xeb ntawm tooj liab, uas yog kev txo qis ntawm cov tooj liab coj los ntawm kev tsim cov tooj liab Oxide tshwm sim los ntawm kev cuam tshuam rau huab cua.

Tsis tsuas yog nws ntxiv dag zog rau cov kab, tab sis kuj nws yooj yim soldering ntawm cov khoom. Yog li ntawd nws yog yeej-yeej.

Txhawm rau ua qhov no, tsuas yog siv qee tus lej ntawm cov laug ntawm cov hlau txuas thiab maj mam swb nws hla cov kab.

Ua ntawv thov ntawm cov kab ua ntej ua qhov no ua rau muaj txiaj ntsig zoo dua.

Thaum koj ua tiav nrog cov laug, koj li PCB yuav zoo li cov tshaj tawm saum toj no, txias.

Kauj Ruam 8: Nrog koj zoo siab

Nrog koj zoo siab ua tus PCB hauv tsev koj tus kheej thiab kawm paub yuav ua li cas. Tam sim no koj tau qhib rau lub ntiaj teb tshiab ntawm cov khoom siv hluav taws xob uas koj tuaj yeem yooj yim kov yeej cov teeb meem nyuaj nrog PCBs uas zoo li tsis yooj yim sua siv cov laug cam qauv.

Tom qab ua tiav PCB, tsuas yog ntxig thiab muab cov khoom sib txuas ua ke los ntawm kev hais txog cov txheej txheem ntawm txoj haujlwm koj tab tom ua.

Kuv tau txuas cov duab ntawm kuv PCB tom qab txhua qhov khoom siv tau muab tso rau hauv kom muab koj lub tswv yim ntawm qhov ua tiav PCB zoo li cas.

Nws yog rau qhov kev qhia no. Yog tias koj muaj kev tsis ntseeg, thov tawm tswv yim. Tsis txhob hnov qab ua raws kuv yog tias koj nyiam cov lus qhia no. Tsis tas li, tshaj tawm cov duab ntawm yuav ua li cas koj cov PCBs tig tawm!

Khaws Tinkering!

Kuv yuav txaus siab rau nws yog tias koj txhawb nqa kuv ntawm Patreon.
