Nyob zoo txhua tus, hnub no kuv yuav qhia koj yuav ua li cas thiaj ua tau PCB zoo, txhawm rau txhim kho koj cov phiaj xwm hluav taws xob. Cia peb pib!

Kauj Ruam 1: Yam Koj Yuav Tsum Tau Yuav

Lub thawv raug

Presensitized epoxy

Tin tov (yeem tab sis pom zoo)

NaOH (sodium hydroxide)

FeCl3

Acetone (koj tuaj yeem pom nws hauv khw muag khoom)

(Nov yog qhov txuas mus rau qhov haujlwm cuam tshuam nrog PCB koj yuav pom hauv qhov kev qhia no: Lub Tshuab Tswj Lub Computer)

Kauj Ruam 2: Teeb duab PCB

Yog tias koj twb tau tsim koj li PCB hauv cov ntawv, koj tuaj yeem hla cov kauj ruam no Kuv tab tom siv Proteus software los kos kuv cov PCBs, tab sis koj kuj tuaj yeem siv Fritzing software los ua qhov ntawd. Qhov tseem ceeb tshaj plaws yog tias koj tuaj yeem xa koj tus qauv tsim mus rau hauv.pdf cov ntaub ntawv. PDF khaws qhov loj me yog li yog tias koj luam cov ntawv no mus rau 1: 1 nplai, koj yuav tsis muaj teeb meem teev tom qab luam ntawv.

Kauj Ruam 3: Luam Ntawv Artwork

Tam sim no luam tawm PCB tsim ntawm cov ntawv pob tshab Kuv qhia koj kom luam tawm tsawg kawg 3 daim qauv ntawm daim duab, koj yuav tau txais txiaj ntsig zoo dua vim tias qhov tsis pom kev yuav zoo dua ntawm qhov nthuav tawm …

Kauj Ruam 4: Teeb Tshuaj Tshuaj

Hauv cov theem no, hnav cov hnab looj tes thiab ua haujlwm hauv thaj chaw muaj cua nkag tau zoo thiab hnav ib lub iav. Koj yuav tuav cov hauv paus muaj zog thiab cov kua qaub. Ib txhia ntawm lawv yooj yim ua pa. Kuv kuj qhia koj kom hnav lub tsho tiv thaiv kab mob lossis khaub ncaws qub vim tias qhov chaw hlau chloride tsis tuaj yeem ntxuav tau. Nws cia qhov qias neeg daj-xim av xim…

/! / Tsis txhob nchuav kua uas muaj hlau rau hauv ib puag ncig /! / Siv lub raj mis tshuaj khib uas koj tuaj yeem muab rau qhov chaw pov tseg.

Npaj da dej ntawm tus neeg tso dej rau prepositive sensibilized epoxy. Nws tsuas yog sodium hydroxyde (concentration 15g/L) Cia nws mus rau chav sov. Npaj lwm qhov da dej nrog kev daws cov hlau III chloride (FeCl3) Yog tias koj xav kom cov tshuaj tiv thaiv kom nrawm dua, koj yuav tsum ua kom cov tshuaj tiv thaiv nruab nrab ntawm cov kua qaub (FeCl3) thiab tooj liab ntawm PCB, nws txhais tau tias koj yuav tsum tau ua kom sov hlau III tshuaj chloride. Txhawm rau ua qhov ntawd, Kuv siv chav da dej kub (saib cov duab) Yog tsis muaj qhov no, qhov txiaj ntsig yuav tsis zoo li qhov xav tau.

Kub cov dej hauv lub rhaub dej kom kub txog 80 ° C, thaum nws kub nchuav dej rau hauv lub khob loj dua li FeCl3 ib qho. Muab tus da dej FeCl3 tso rau hauv cov dej kub.

Tsis tas li npaj cov dej da dej, (dej ua kom dej zoo dua) ntxuav PCB ntawm txhua kauj ruam. Nws kuj yog ib lub tswv yim zoo kom khaws cov ntawv nyob ib sab ntawm koj … Thaum koj ntxuav PCB, nqus dej rau nws kom tsis txhob ua kom da dej tom ntej.

Kauj Ruam 5: Tshaj tawm PCB

Cia peb teeb lub thawv UV-lub teeb pom kev zoo.

Nqa thawj daim duab thiab muab tso rau ntawm lub lauj kaub nrog daim kab xev nplaum. (Ceev faj txog kev taw qhia ntawm daim duab!)

Tom qab ntawd ntxiv qhov thib ob thiab thib peb tsim rau thawj qhov los txhim kho qhov tsis pom kev. Qhov ua kom yuam kev no yuav tiv thaiv UV hluav taws xob hla kab dub ntawm kev tsim qauv.

Tam sim no koj npaj tau lawm. Koj yuav ua haujlwm nrog cov duab hluav taws xob, yog li koj yuav tsum tau ua haujlwm nyob rau hauv qhov chaw uas qhov ci ci tau txo kom txog thaum PCB tsis tsim.

Npaj kom pib? Mus!

Ua tib zoo tshem cov zaj duab xis tiv thaiv ntawm PCB. Muab sab sab nkag rau hauv qhov tsim thiab ruaj ntseg nws nrog daim kab xev. Muab tag nrho cov no tso rau hauv lub thawv tso tawm, sab nkag mus ntsib lub raj UV thiab kaw lub thawv.

Qhib nws nruab nrab ntawm 2 'txog 2'30 tsis muaj ntxiv lawm.

Kauj Ruam 6: Txhim Kho PCB

Muab nws tam sim rau hauv chav da dej sodium hydroxide, lub ntsej muag nkag siab. Koj yuav tsum pom tam sim xim xiav-ntshav (qee zaum txho) nkag mus rau hauv sodium hydroxide. Maj mam da dej kom txog thaum koj zoo saib tsim. (Ib ncig 30 " - 60")

Ntxuav PCB rau hauv chav da dej.

Kauj Ruam 7: Sau PCB

Hauv cov kauj ruam no, PCB tsis muaj teeb meem rau txhua qhov, koj tuaj yeem hloov lub teeb!

Tam sim no tso PCB tooj liab-ntsej muag nce rau hauv cov kua qaub (FeCl3) thiab maj mam co nws rov qab thiab mus tom ntej. Kev daws teeb meem ib txwm xav tau txav mus rau qhov kev tawm tsam tshwm sim. (Kwv yees li 20 'txog 40' nyob ntawm qhov ntsuas dej da dej, thaj tsam tooj liab kom tsis sib haum thiab qhov sib xyaw ntawm FeCl3 daws.)

Thaum tag nrho cov tooj liab tau yaj los ntawm cov kua qaub, tshem tawm PCB thiab ntxuav nws mus rau hauv lwm chav da dej thiab ua kom qhuav.

Kauj Ruam 8: Ntxuav PCB

Tam sim no koj yuav tsum tau tshem tawm cov tshuaj ntxiv ntawm lub Circuit Court. Txhawm rau ua qhov ntawd, tso lub PBC rau hauv lub dab da dej acetone. Acetone yuav dhau los ua ntshav. (Ib puag ncig 10 " - 20") Cov tooj liab tam sim no raug nthuav tawm.

Tom qab ntawd ntxuav PCB rau hauv dej, thiab koj tau ua tiav!

Kauj Ruam 9: Tinning PCB

Nws yog cov kauj ruam xaiv tau tab sis kuv tshaj tawm koj ua nws vim tias nws yuav pab koj kom cov khoom sib txuas thiab tiv thaiv kev xeb.

Muab PCB tso rau hauv qhov chaw da dej tas thiab nchuav me ntsis ntawm tin II chloride tov rau nws. Nws yuav tso cov tin rau ntawm Circuit Court.

*** Ua tau zoo! *** Koj tau ua tus kws tshaj lij PCB!

Kauj Ruam 10: Drilling PCB

Siv qhov ntsuas ntsug thiab 0.8mm laum me ntsis txhawm rau txhawm rau txhua qhov, thiab yog tus pin ntawm cov khoom siv loj dhau mus dhau, siv 1.2mm laum me ntsis kom nthuav dav thawj lub qhov. (Ib txwm pib nrog lub qhov me me uas koj muaj, txhawm rau qhov qhov tseeb! Nws yog qhov tseem ceeb heev!)

Thiab koj PCB tau ua tiav! Tsuas yog qhov uas tshuav yog kom muab koj cov khoom tso rau ntawm nws!

Kuv vam tias koj nyiam qhov kev qhia no

Yog tias koj muaj lus nug, tawm lus tawm!;)
