Tom qab ntawd sib sau ua ke tag nrho cov khoom raws li koj qhov yooj yim. Rau kev koom nrog cov khoom siv kev siv airwire kom ntseeg tau tias koj yuav siv cov txheej hauv qab, daim phiaj yuav nyob hauv hli thiab txoj kab dav dav dav dav 0.4064

Tom qab koom nrog txhua qhov khoom Siv Siv daim iav los tsim cov duab ntawm qhov muaj nuj nqis thiab npe.

Rau kev siv daim iav ua ntej xaiv cov cuab yeej tsom iav thiab tom qab ntawd qhov tseem ceeb, npe. Ntxiv tom ntej, txuag lub rooj tsavxwm nrog txhua lub npe, kos DRC txhawm rau txheeb xyuas qhov ua yuam kev. Yog tias tsis muaj qhov yuam kev peb zoo mus tom ntej.

Txhawm rau pom kev saib ua ntej ntawm pawg thawj coj saib mus rau kev tsim khoom.

Tam sim no peb tau ua tiav nrog pawg thawj coj.

Cov kauj ruam tom ntej yog luam tawm ckt ntawm cov ntawv ci. Rau qhov nyem rau ntawm qhov luam tawm, koj yuav pom ib nplooj ntawv raws li qhia hauv qab no.

Xaiv dub hauv kev xaiv, yog tias koj siv ntau txheej txheej ces koj kuj yuav tsum xaiv daim iav

Xaiv qhov ntsuas qhov ntsuas 1.042 Tom qab ntawd txuag nws rau pdf lossis luam tawm nws

Tom qab luam tawm ckt, 1. Tshem tawm txheej txheej oxidation uas siv cov ntawv xuab zeb (400) siv lub teeb tes.

2. Ntxuav nws siv isopropanol lossis propan-2-ol lossis yog tias koj xav tau koj tuaj yeem siv cov tshuaj yuag dua thiab.

3. Muab cov ntawv ckt luam tawm rau ntawm FR4 ntawv uas siv daim kab xev.

4. Ua kom sov nws siv cua sov hlau (5 -10 feeb) kom ckt yuav luam tawm ntawm daim ntawv FR4. Soak board hauv dej rau 2-3 feeb. Tom qab ntawd tshem daim kab xev thiab ntawv.

5. Muab nws tso rau hauv cov tshuaj ferric chloride li 10 feeb kom tshem tau cov tooj liab nkag mus thiab ntxuav nws nrog dej.

6. Tshem tawm txheej uas siv cov ntawv xuab zeb (400) lossis Acetone.
