Txoj cai ntawm Far Infrared Thermometer Performance Index ntawm Far Infrared Thermometer
1. Test kuj loj
Ua ntej siv cov hlau soldering, ntsuas qhov kev tiv thaiv ntawm lub hwj chim ntsaws los txiav txim seb puas muaj cov hlau soldering.
Qhov tsis kam ntawm cov hluav taws xob soldering hlau yog ntau txhiab ohms, uas txhais tau tias nws tuaj yeem siv tau. Yog tias qhov tsis kam yog xoom lossis tsis kawg, nws yuav tsis ua haujlwm. Yog hais tias qhov tsis kam yog xoom, nws txhais tau hais tias muaj luv luv Circuit Court nyob rau hauv lub soldering hlau, thiab yog hais tias tus kuj yog infinite, nws txhais tau hais tias muaj ib tug qhib Circuit Court nyob rau hauv lub soldering hlau.
2. Tin plating tiv thaiv
Thaum siv ib tug tshiab soldering hlau thawj zaug, xyuas kom meej tias lub taub hau ntawm lub soldering hlau yog ci, sov lub solder thiab dipped nyob rau hauv rosin nyob rau tib lub sij hawm, kov lub solder hlau ob peb zaug, thiab sib npaug ntawm lub taub hau. soldering hlau nrog ib txheej ntawm solder. Nws tsis yog tsuas yog yooj yim rau kev siv tom ntej, tab sis kuj tiv thaiv oxidation ntawm lub ntsis ntawm cov hlau soldering.
Lub qub hluav taws xob soldering hlau tau siv los ntev, thiab yuav muaj txheej txheej ntawm oxide nyob rau saum npoo ntawm cov hlau taub hau, uas ua rau cov hlau taub hau tsis yooj yim rau noj tin.
Cov oxide nyob rau saum npoo ntawm cov hlau nplaum tuaj yeem raug tshem tawm nrog cov ntawv xuab zeb zoo lossis cov ntaub ntawv ua kom lub ntsej muag ci. Tom qab ntawd, raws li txoj kev kho mob ntawm ib tug tshiab hluav taws xob soldering hlau, tusyees txheej txheej ntawm lub soldering hlau taub hau nrog ib tug txheej ntawm solder.
3. Soldering hlau tsis noj tin
Thaum cov hlau nplaum tsis noj cov tin, feem ntau tsis tas yuav xav txog seb nws puas yog tshwm sim los ntawm cov pa oxygen tsis txaus. Oxygen tsis muaj dab tsi ua rau cov cua sov ntawm cov hlau soldering. Lub soldering hlau heats thiab melts lub solder hlau los ntawm alternating tam sim no.
soldering hlau tsis noj tin, vim hais tias cov hlau soldering yog energized ntev heev tsis siv nws, uas yuav ua rau kom lub oxidation ntawm lub soldering hlau core thiab hlawv nws, shortening nws cov kev pab cuam lub neej. Nyob rau tib lub sijhawm, nws yuav ua rau lub hau ntawm cov hlau soldering yuav oxidized los yog hlawv kom tuag los ntawm cua sov rau lub sijhawm ntev.
Qhov no tau ua rau muaj teeb meem uas hluav taws xob soldering hlau tsis noj tin. Nyob rau hauv tus txheej txheem ntawm tsis noj tin, ib qho tshuaj tiv thaiv oxidation tshwm sim, thiab tshuaj lom neeg cov tshuaj tiv thaiv tshwm sim ntawm cov khoom thiab oxygen, thiab cov pa oxygen muab oxygen.
Thaum lub sij hawm siv hluav taws xob ntev dhau lawm thiab qhov kub nce siab, cov tshuaj tiv thaiv cov tshuaj tiv thaiv yog muab rau cov tshuaj tiv thaiv oxidation, thiab oxidation ceev ntawm lub taub hau hlau thiab cov tub ntxhais hlau ntawm cov hluav taws xob soldering hlau yuav nrawm dua.
