Taw qhia rau txoj kev kho mob ntawm kev hlawv cov soldering hlau taub
1. Ua ntej, so nrog cov hlau shading nqus tsev vacuum, tom qab ntawd pheej rov ua kom muaj ob peb zaug kom nws ci.
2. Ua ntej, kho qhov ntsuas kub mus rau 300 degree c, ntxuav lub tshuab dhos tshuab hluav taws xob, thiab tshuaj xyuas cov xwm txheej ntawm cov tshuab ntxhua khaub ncaws. Yog hais tias tus Tin plating txheej ntawm lub tshuab dhos tshuab raj muaj cov xim oxides.
3. Thov ib txheej tshiab ntawm cov ntaub pua tsev thiab tom qab ntawd ntxuav cov pob qij txha sib dhos nrog ntxuav daim txhuam cev. Rov ua cov txheej txheem ntxuav kom txog thaum cov oxide tshem tawm tag nrho, thiab tom qab ntawd txheej txheej tshiab.
4. So cov tshuaj txhuam hniav lossis polishing muab tshuaj txhuam, ceevfaj tsis txhob thov ntau zog.
Cov hau kev los tiv thaiv kev kub siab ntawm cov lus qhia hlau soldering
1. Cov qauv sib txawv
Ua raws li cov hnub nyoog ntawm cov hlau soldering, nws feem ntau pib hlawv tawm tom qab tau ua tsis tu ncua rau {{}} feeb. Yog li ntawd, yog tias cov hlau soldering yog txuas ntxiv powered rau 15 feeb, lub hwj chim yuav tsum tau txiav tawm rau {2}} feeb ua ntej yuav rov ua dua.
2. Cov qauv cua txias
Siv tus kheej-tsim bracket kom txias cov taub hau hlau cam tuaj yeem tiv thaiv cov tshwm sim ntawm "hlawv kom tuag".
Cov txheej txheem ntawm kev ua lub tshuab txias txias yog coj cov khib nyiab hlau ua ke, muab cov ntaub qhwv ntsej muag, npuaj ob feem peb ntawm lub peev xwm ntawm cov dej. Ib qho txias bracket rau cov hluav taws xob tshuab hluav taws xob yog npaj. Tso cov ntxeev ntawm cov hlau soldering rau hauv lub raj cwj mem tuaj yeem ua kom cov hlau siv sijhawm ntev uas tsis muaj "hlawv" tshwm sim.
