Qhuav ntawm luam Circuit Court laug cam nyob rau hauv tsev: nta ntawm tus txheej txheem

Qhuav ntawm luam Circuit Court laug cam nyob rau hauv lub tsev yog ua tau. Txawm li cas los, qhov no yuav tsum tau ib tug qhov chaw, cov khoom thiab lub sij hawm. Qhov kom zoo dua ntawm no lub caij no yog hais tias lub xov tooj cua ua hauj lwm rau nws nti thiab nraaj.

Kev npaj: xaiv cov ntaub ntawv

Qhuav ntawm luam Circuit Court laug cam nyob rau hauv tsev pib nrog tus sau los ntawm qhov tsim nyog Cheebtsam. Koj yuav tsum tau:

• ib tug computer thiab ib tug laser tshuab luam ntawv (dub thiab dawb);
• yees duab ntawv;
• irons thiab soldering;
• dej, flux, hlau chloride, acetone, tin;
• mog (unilateral) PCB, thiab nws saum npoo yuav tsum tau muaj ib tug tooj liab txheej.

Thaum tag nrho cov Cheebtsam yog tau koom ua ke, koj yuav pib qhov siv thiab ua luam Circuit Court laug cam nyob rau hauv tsev. Ua ntej koj yuav tsum kos rau hauv Circuit Court. Rau lub hom phiaj no lub feem ntau yooj yim graphics editor, txawm hais tias koj yuav nrhiav qhia tshwj xeeb uas tsim rau lw lub qhov kev pab cuam rau cov laug cam. Thaum no tus taw tes koj yuav tsum txiav txim siab nyob rau hauv cov kev ua blocks. Thaum cov Circuit Court yog twv, nws yuav tsum tau luam. Cia li kom nyob rau hauv lub siab hais tias nws yuav tsum tau daim iav.

Tus txheej txheem fabricating lub Rooj Tswjhwm Saib

Rau ntawm no theem, cov duab yuav tsum tau ua ntawv thov mus rau qhov chaw ntawm lub kho lub caij. Ib cheeb tsam nyob rau hauv uas cov duab no tsis yog ntaus thwj, etched yooj yim tshuaj reagents. Tsuas yog koj yuav tsum nyob twj ywm rau hauv Circuit Court board.

Qhuav ntawm luam Circuit Court laug cam nyob rau hauv tsev yuav tsum tau ua zoo zoo heev. Piv txwv li, koj muaj peev xwm tsis kov ob txhais tes ntawm cov ntawv luam daim duab. Tsis tas li ntawd xyuam xim rau cov ntawv ci nto: nws ua txhua yam rau yuav li huv si li sai tau. Yog hais tias koj pom tau tias nws yog ua raws li los ntawm oxidation, sim los daws kom tau nws siv zoo ntwav txhuam ntoo. Lawm, nws yog ntshaw kom degrease tus nto nrog acetone los yog lwm yam kuab. Tom qab cov kev kho mob, tsis txhob kov cov PCB.

Tam sim no daim duab koj xav kom hloov mus rau lub npaj nto. Rau no leaflet ua tib zoo thov mus rau PCB thiab ironed hlau, rhuab mus rau ib tug tshaj plaws kub. Cov duab nyob rau tib lub sij hawm yuav tsum tsis txhob txav mus rau hauv txhua rooj plaub. Qhov no txoj kev kav ib ob peb feeb, kom txog thaum lub nplooj tig daj.

Tam sim no koj yuav tsum muab tso rau hauv daim ntawv nyob rau hauv lub neej yav tom ntej tus dej mus rau lub dhau heev lawm daim ntawv soaked thiab nws yuav sai sai ntxuav tawm. Yog hais tias cov duab nyob rau hauv tus nto ntawm lub PCB kom tau qualitatively thiab yog, koj yuav npaj mus rau lub kauj ruam tom ntej.

etching txoj kev

Yuav kom daim duab twb nrees nraim nyob rau hauv tus ntawv ci tsim txoj kev ntawm luam Circuit Court laug cam yuav siv cov tov ntawm ferric chloride. Es tsis txhob qhov ua piv txwv cov ntaub ntawv uas tej zaum yuav siv tooj liab sulfate (100 grams do lub hmoov thiab 200 g ntawm ntsev ib liter ntawm dej sov). etching txoj kev kav txog 15 feeb.

Tom qab tag nrho cov saum toj no kev ua yuav sposlosnut board nrog dej huv thiab tho qhov tsim nyog qhov rau cov ntsiab lus. Nws tseem yog ntshaw kom ntxuav lub saum npoo nrog ib tug qauv los ntawm txoj kev ntwav txhuam ntoo. Nyob rau hauv tib txoj kev uas nws ua tus zus tau tej cov multilayer luam Circuit Court laug cam.

Rau cov khoom yog ntau zoo nkauj, muaj peev xwm npaj ntawm cov. Rau lub hom phiaj no yog ib tug kev tshuaj, mus rau hauv uas lub Rooj Tswjhwm Saib. Tom qab ua lub nyiaj conductors tau xim.
