Tsim nyog
- - ntawv ci iav fiber ntau laminate;
- - tooj liab hlau;
- - soldering hlau;
- - ntxooj yeeb;
- - tus pas ntsuas;
- - foob.
Cov Lus Qhia
Kauj ruam 1
Xav txog ib qho tseem ceeb, yog tias koj lub modem tsis muaj qhov chaw nres nkoj txuas rau lub kav hlau txais xov, ces koj yuav tsum tau nruab nws es tsis txhob siv tus qauv, uas tom qab ntawd yuav tsis ua haujlwm txhua. Ua ntej tshaj, npaj txhua qhov tsim nyog los ntawm qhov koj yuav tsim tus kav hlau txais xov.
Kauj ruam 2
Txiav ob daim hlab hlau lossis ntawv ci-clad fiberglass. Lawv yuav tsum yog 1-2 hli tuab, 10 mm dav, thiab 50-70 cm ntev. Npaj ib co ntawm tooj liab xaim. Nws cov tuab yuav tsum tsis pub tshaj 2 hli. Koj tuaj yeem siv tooj liab hlau rau qhov no.
Kauj ruam 3
Txheeb solder lub pre-txiav pieces ntawm tooj liab xaim mus rau lub npaj strips. Ua kom qhov kev ncua deb ntawm cov pins tib yam, tab sis nws yuav tsum tsis txhob loj dhau. Nyob rau hauv tag nrho, koj yuav xav tau ham 12-14 pieces rau ib phaj. Cov pins yuav tsum staggered ntawm ob sab ntawm daim hlau.
Kauj ruam 4
Siv ib txoj hlua hlau txiav, ntsuas qhov ntev ntawm tag nrho cov roj pins. Tam sim no txiav plaub lub kab sib tw nrog qhov ntev ntawm 15x10 hli los ntawm fiberglass Tho qhov rau cov coaxial cable hauv lawv.
Kauj ruam 5
Xaiv peb daim hlau thiab tshem qee cov ntawv ci ntawm ob sab. Tso daim plaub tsis pauv.
Kauj Ruam 6
Muag cov phiaj kab no rau ib qho ntawm rab koob uas koj tsim. Tso cov phaj uas tsis ci hauv ib lub npoo. Tam sim no ham lub phaj thib ob rau cov qauv tsim.
Kauj Ruam 7
Tam sim no siv 50 ohm coaxial cable thiab thawb nws los ntawm kev npaj qhov. Qhov kawg ntawm lub cable yuav tsum txuas nrog qhov tsis txaus. Muab txoj hlua khi rau ib qho phaj thiab ntawm tus neeg xyuas pib rau lwm yam. Nco ntsoov kaw ntaws cov xov tooj ham. Koj tuaj yeem siv kua nplaum lossis foob rau qhov no.
Kauj ruam 8
Tam sim no ua tus kav hlau txais xov mount coj mus cuag nws rau USB modem, los sis cam cov braid thiab cov tub ntxhais rau nws cov insides siv cov kav hlau txais xov txheem. Nruab cov kav hlau txais xov tsim nrog pins ntsug. Txuas tus kav hlau txais xov mus rau modem.
