nyob zoo hauv cov lus qhia no kuv yuav qhia koj li cas kuv tau ua kuv cov ntawv luam tawm Circuit board nyob hauv tsev.i tsis nyiam kub xovxwm xov tooj cua txoj kev uas yog vim li cas kuv siv txoj kev hloov txias nrog me ntsis ntswj.

sib nrug los ntawm qhov ntawd kuv tseem yuav qhia koj li cas koj tuaj yeem siv rab koob ua lub ntsis thiab pcb etching siv cov tshuaj muriatic.

rau ntau cov vis dis aus thiab phiaj xwm sau npe yuav kuv tus YouTube channel nyem ntawm no- BHARAT MOHANTY

Kauj ruam 1:

koj xav tau:-

{1} tooj liab clad

{2} tshuaj tsuag qhov mob

{3} laser tshuab luam ntawv

{4} koob

{5} laum/pcb tes xyaum

{6} muriatic acid

{7} hydrogen peroxide

qhov chaw hauv Circuit:-

{1} transistor (bc547) 4

{2} tshaj tawm (6 volt) 4

{3} resistor (1k) 4

{4} diode (hauv 4007) 4

{5} coj (yeem) 4

{6} poj niam thiab txiv neej lub taub hau

Kauj ruam 2:

ua ntej tshaj plaws peb yuav tsum tsim pcb, rau qhov koj tuaj yeem siv ib qho pcb cad software.there muaj qee qhov online pcb tsim lub tswv yim muaj nyob zoo li eagle, yooj yim eda tab sis yog tias koj xav tau kev mob siab rau pcb cad

software zoo li kuv ua koj tuaj yeem siv kicad, librepcb lossis fritzing.all cov software thib peb yog pub dawb thiab qhib-qhov chaw thiab muaj rau lub qhov rais, mac thiab linux.i nyiam fritzing vim nws yooj yim nkag siab txawm tias tus pib tuaj yeem ua haujlwm nrog nws.here Kuv tab tom tsim kev xa tawm raws tus tsav tsheb ntawm ib pawg thawj coj.

Kauj ruam 3:

tom qab tsim lub rooj tsavxwm ntawm pcb cad kuv luam tawm (daim iav daim duab) ntawm daim ntawv uas siv lub tshuab luam ntawv laser.here kuv siv daim ntawv a4 loj li niaj zaus tab sis cov ntawv xov xwm qub yog qhov zoo tshaj. tom qab ntawd kuv ntsuas thiab txiav cov tooj liab raws li qhov loj ntawm Circuit template.

Kauj ruam 4:

ua ntej hloov pauv toner peb yuav tsum tau ntxuav cov nplaim tooj liab. nws muaj cawv thiab qee cov roj ntuj (kuv tsis tuaj yeem qhia koj qhov muaj pes tsawg leeg vim yog qhov teeb meem ntawm tus tswv tab sis koj tuaj yeem tshawb xyuas nws ntawm cov tshuaj tsuag tau) cov tshuaj tsuag no cuam tshuam nrog lub toner thiab ua rau nws nplaum rau lub sijhawm luv. nws ntawm tooj liab npog tam sim tom qab tshuaj tsuag. Lau nws kom qhuav yam tsawg 5 feeb. tom qab ntawd tshem daim ntawv.thiab koj yuav tau txais daim ntawv zoo zoo yog tias nws ntub me ntsis ces cia nws qhuav rau lwm 5 feeb lossis yog tias koj xav tias qee qhov tsis tau luam tawm ces kos nws nrog tus cim ruaj khov.

Hloov tshiab:-

muaj pes tsawg leeg yog

diclofenac diethylamine, linseed roj, methylsalicylate, menthol

Kauj ruam 5:

rau pcb etching Kuv tab tom siv ib feem muriatic acid ob thiab ib nrab ntawm hydrogen paraoxide.muriatic acid tsis muaj dab tsi tab sis diluted hcl nrog ntau ntau ntawm impurities.here hydrogen peroxide ua raws li oxidiser.now kuv yuav muab tso rau ntawm qhov kev daws teeb meem no, Kuv tabtom nplawm qhov kev daws teeb meem kom ua kom nrawm dua.after etching muab pcb hauv dej thiab ntxuav nws.

Kauj Ruam 6:

tam sim no nws yog lub sijhawm tshem tag nrho cov toner los ntawm pcb rau qhov uas koj tuaj yeem siv thinner, acetone, ntsia thawv polish tshem tawm lossis tsuas yog txhuam nws tawm. yog li kuv siv rab koob los ua qhov.

Kauj ruam 7:

tom qab lub qhov qhov sib dhos ua ke txhua qhov thiab muab tshuaj txhuam nws …. thiab koj daim ntawv luam tawm Circuit Board tau npaj siv …
