Tej kev soldering yuav tsum muaj qhov tseeb thiab qee yam txuj ci, thiab roj teeb soldering - ntau heev dua. Lub roj teeb zoo li yuav ua kom sov dhau thiab tuaj yeem muab pov tseg. Tab sis tseem, koj tuaj yeem ua tus txheej txheem no koj tus kheej yog tias koj muaj cov hlau soldering, qee yam cuab yeej thiab ncaj tes. Lub qhov muag ntshai, txhais tes tau ua raws li lawv hais, yog li muaj kev ywj siab xav tawm tsam!

Cov Lus Qhia
Kauj ruam 1
Maj mam ntxuav qhov chaw ntawm lub roj teeb. Txhawm rau tiv thaiv kom nrawm rau oxidation, siv fluxes rau thaj chaw ntub dej. Lawv yuav ua kom muaj kev npliag ntawm molten solder thiab tus ham yuav muaj zog. Thaum ua haujlwm nrog roj teeb, nws yog qhov zoo tshaj plaws kom tsis txhob siv cov hluav taws xob refractory solders, vim tias lawv yuav tsum muaj qhov kub dua uas cov roj teeb yuav tsis tuaj yeem tiv taus.
Kauj ruam 2
Xaiv lub siab melting solder - nws tsis muaj zog npaum li lub siab melting ham, tab sis yuav ua haujlwm rau roj teeb. Tseem muaj qhov tsawg kawg-melting alloys nrog txawm tias qis dua melting cov ntsiab lus (txog 100 degrees), tab sis hmoov tsis lawv tsis tshua ruaj. Lawv siv rau soldering transistors thiab muaju.
Kauj ruam 3
Thaum soldering, siv cov fluxes los tiv thaiv cov hlau saum npoo thiab txhim kho solder ntub dej rau cov hlau saum npoo ntawm lub roj teeb. Cov kev coj ua no yog qhov tsim nyog vim tias thaum lub sijhawm soldering, qhov kub tau nce siab, thiab lub tshuab oxidation nce ntxiv, vim qhov twg tus xaim ua rau cov khoom tsis zoo. Rau cov roj teeb soldering, fluxes yog haum, uas tiv thaiv cov hlau qhov chaw kub los ntawm oxidation. Hauv qhov no, rosin tau zoo tag nrho.
Kauj ruam 4
So cov leeg nrog txoj phuam, yav tas los ua cov dej noo rau hauv acetone, tsis hais hom flux siv. Tsis tas li ntxuav lub rooj zaum nrog txhuam nrog txhuam hauv cov kuab tshuaj kom tshem tawm cov khoom seem thiab flux.
Kauj ruam 5
Yog tias koj tsis pom lwm yam dhau ntawm cov txhuas, yuav tsum ceev faj vim tias nws yog fusible. Txawm lub sijhawm nyob tsawg tshaj plaws los ntawm kuaxeb nyob hauv lub qhov cub yuav ua rau yaj. Yog li ntawd, thaum txhav khoom, muab lub teeb sib txuas rau cov chaw nres tsheb thiab tsis txhob taw tes ncaj qha rau nws.
Kauj Ruam 6
Tsis txhob siv cov tin yajthem yog tias lub roj teeb ua los ntawm txhuas. Tin yog soluble hauv electrolyte, yog li tsuas yog siv cov hmoov txhuas xwb. Saib xyuas kom zoo rau cov nplaim taws ntawm lub tshuab ntsuas hydrogen kom nws tsis txhob ntau dhau ntawm cov hmoov txhuas thiab ua kom puas lub roj teeb. Cov nplaim ntev ntawm lub txiv mis yuav tsum tsis pub dhau 15 millimeters.
