1. Kev siv thiab kev saib xyuas ntawm hluav taws xob soldering hlau
1. Sim siv cov vuam uas tsis tshua muaj kub
Qhov kub thiab txias yuav ua kom cov oxidation ntawm cov hlau taub hau thiab txo lub neej ntawm cov hlau taub hau. Yog tias qhov ntsuas kub siab tshaj 470 degree, nws oxidizes ob zaug sai li 380 degree.
2. Tsis txhob tso siab ntau dhau
Thaum soldering, tsis txhob siv lub zog ntau dhau, txwv tsis pub lub hau ntawm cov hlau yuav puas thiab deformed. Ntev npaum li qhov ntxeev ntawm cov hlau soldering ua rau muaj kev sib cuag nrog cov sib koom ua ke, cov cua sov tuaj yeem hloov mus. Tsis tas li ntawd, xaiv txoj cai soldering hlau taub kuj tseem tuaj yeem pab hloov cov cua sov.
3. Nco ntsoov khaws lub hau ntawm cov hlau soldering rau ntawm tin
Qhov no txo qhov muaj feem ntawm oxidation ntawm lub taub thiab ua rau lub taub hau ntev dua. Tom qab siv, qhov kub ntawm cov hlau taub hau yuav tsum tau txo qis me ntsis ua ntej ntxiv cov hlau tshiab, kom cov tinned txheej muaj cov nyhuv zoo dua los tiv thaiv oxidation.
1. Kev daws teeb meem ntawm hluav taws xob soldering hlau
1. Qhov ntsuas kub tsis teeb
Tshawb xyuas cov xov hlau xoob, fuse, 24V, soldering hlau luv luv, thiab hauv av caij nplooj ntoos hlav tig.
Thaum kuaj xyuas cov ntawv pov hwm, thawj zaug tua lub hwj chim, tshem tawm cov hlau nplaum, tig lub ntsuas cua sov, loosen cov ntsia hlau, tig nws, thiab maj mam tshem lub hau sab saud.
Yog tias 24V zoo, xyuas cov hlau soldering rau luv luv Circuit Court.
Lub taub hau ntawm cov hlau tuaj yeem tsuas yog ntxuav nrog daim txhuam cev ntxuav, tsis polished nrog daim ntawv gauze.
2. Lub teeb yog nyob rau thiab cov hlau soldering tsis kub
Tshawb xyuas cov xov hlau puas thiab puas cua sov cov ntsiab lus nyob rau hauv lem.
Tig lub multimeter mus rau lub beeping iav, ntsuas seb cov hlau puas puas, ntsuas qhov kev sib txuas ntawm lub taub hau ntawm lub taub hau ntawm cov hlau thiab cov hlau, counterclockwise 1, 2, 3, 4, 5, 1 yog cov hlau liab, ntev li ntev tau. nws rings, nws txhais tau tias tib yam; 2 yog cov hlau dawb, 3 yog cov xaim hauv av, 4 yog cov xaim ntsuab, thiab 5 yog cov xaim xiav. Yog hais tias muaj ib tug disconnected hlau, hloov cov hlau.
Yog tias cov hlau tsis zoo, xyuas cov khoom cua sov. 4 thiab 5 yog cov hlau ntsuab thiab xiav xaim feem, lawv txuas nrog lub rhaub, qhov kev tiv thaiv ib txwm muaj nyob nruab nrab ntawm 2.6-3.8, yog tias nws txawv txav, nws yuav tsum tau hloov.
Ceramic rhaub. 1 thiab 2 yog cov kab liab thiab dawb, lawv txuas nrog lub sensor, tus nqi kuj tseem nyob nruab nrab ntawm 43-58, yog tias nws txawv txav, lub sensor yuav tsum tau hloov.
