Soldering kev txuas ua ke nrog kev coj cov hlau lead loj txaus tuaj yeem nqa tawm hauv tsev. Qhov loj tshaj plaws yog xaiv txoj cai soldering hlau rau qhov no thiab txhim kho kev txawj ntse los siv nws.
Cov Lus Qhia
Kauj ruam 1
Thaum xaiv cov hlau soldering, nco ntsoov tias cov ntsis taub tseem ceeb tshaj qhov muaj hwj chim. Nws yog qhov yooj yim dua rau solder microcircuits nrog qis-zog soldering hlau nrog txhav loj dua li nrog lub zog, tab sis nrog lub taub loj dua. Txawm li cas los xij, nws ua rau tsis paub mus yuav qhov khoom siv nrog lub zog siab dua 30 W - nws yuav ua kom sov, uas yuav ua rau soldering yuav luag tsis yooj yim. Soldering chaw nres tsheb nrog kev ntsuas kub tsis siv neeg muaj kev yooj yim heev. Lawv siv cov kav hlau uas muaj zog ntau dua, tab sis lawv ib txwm qhib thiab tua kom tswj tau qhov kub thiab txias tas li, ib yam li irons. Teem lub ntsuas kub rau ham uas koj siv (hmoov txhuas lossis tsis muaj txhuas).
Kauj ruam 2
Xaiv koj flux ntse ntsuav. Nws yuav tsum yog qhov nruab nrab (ntawd yog, tsis yog acidic). Txwv tsis pub, qee lub sijhawm tom qab ua tiav qhov kev tshwm sim zoo li lub cev, xeb yuav tshwm sim. Tsis txhob cia li muaj tseeb los ntawm kev tshaj tawm tias tso dej tawm kom dhau mus, yuav daws qhov teeb meem no, vim tias nws tsis tuaj yeem tshem tawm cov kua qaub.
Kauj ruam 3
Muag lub microcircuit npaj rau kev teeb tsa hauv lub qhov ntawm pawg thawj coj raws li hauv qab no. Nco ntsoov tias nws yog taw qhia kom raug ua ntej. Yog tias koj txhob txwm xuas nws ntxeev nws, nws yuav nyuaj rau nws muaj. Cia li nyob rau hauv rooj plaub, thaum txhim kho microcircuit, tsis txhob khoov nws cov coj los ntawm sab nraub qaum - tam sim ntawd koj tseem yuav xav tau soldering.
Kauj ruam 4
Muag lub pins rau cov khoom siv fais fab ua ntej. Tsuas yog tom qab ntawd nqa tawm tib lub haujlwm nrog rau kev saib xyuas cov lus xaus. Yog tias microcircuit nkag siab rau hluav taws xob zoo li qub, siv txoj hlua khi tshwj xeeb txuas nrog los ntawm megohm resistor mus rau cov xaim ntawm cov thawj coj.
Kauj ruam 5
Tsis txhob cia tus coj ntawm microcircuit kom luv luv-circuited nrog ham. Yog tias qhov no tshwm sim, npog lub jumper nrog ntau flux thiab tom qab ntawd ua kom sov cov kev hloov pauv kom txog thaum lawv qhib. Lub tshuab xuas tshuab xuas tshwj xeeb, tooj liab thiab txawm tias ib qho hniav txhuam hniav kuj tseem tuaj yeem pab ntawm qhov no. Muab tshem tawm txoj kev tshem tawm ntau dua tuaj yeem rov siv tau.
Kauj Ruam 6
SMD chips yuav tsum xub tau nias rau lub rooj tsavxwm, ob peb lub koob, thiab tsuas yog tom qab ntawd tuaj yeem muab cov nyiaj so tso tawm tsis tas yuav siv zog. Yog hais tias lub microcircuit yog qhov tsawg heev, siv tweezers kom nws nias nrog tweezers hloov ntiv tes, thiaj li tsis mus hlawv koj tus kheej. Yog tias qhov xav tau, tsis txhob tho qhov nyob hauv pawg thawj coj, txawm tias lub microcircuit tau tsim los rau qhov no. Khoov nws txoj kev mus rau sab toj, tom qab ntawd nws yuav muaj peev xwm mus ua rau lawv rau hauv cov xov tooj sib ceg.
