Thib ob, cov qauv thiab kev ua haujlwm ntawm cov kua siv lead ua kua. Cov kua siv lead ua kua yog qhov sib txawv ntawm cov khoom ib txwm, kua thiab gaseous lub xeev ntawm ib lub xeev, nws yog nyob rau hauv ib tug tej yam kub ntau yam ntawm cov kua thiab siv lead ua ob yam ntxwv ntawm lub xeev teeb meem, nrog ib tug niaj hnub molecular kev npaj ntawm cov organic tebchaw, feem ntau siv cov kua siv lead ua kua rau theem ntawm cov kua siv lead ua kua, lub molecular txheej xwm yog ib tug elongated pas nrig, qhov ntev ntawm 0.1 ~ 1.0% tam sim no siv lead ua kua. yuav ua raws li kev sib hloov 90o, uas ua rau muaj qhov sib txawv ntawm kev xa tawm, kom lub hwj chim muab rau thiab tawm thaum qhov sib txawv ntawm lub teeb thiab tsaus. Cov kua siv lead ua kua ntawm ADF yog ib txoj kev tsav tsheb uas siv ncaj qha rau kev tsav tsheb mus rau qib pixel, kom cov kua siv lead ua kua tso ncaj qha mus rau cov teeb liab siv hluav taws xob. Lub tswv yim tseem ceeb ntawm kev siv hluav taws xob yog ua kom tsis tu ncua ntawm hluav taws xob thiab tsis muaj hluav taws xob siv hluav taws xob ntawm cov khoom siv hluav taws xob sib txuas, thiab qhov sib txawv ntawm kev xa tawm tau tshwm sim raws li qhov loj ntawm daim ntawv thov hluav taws xob.
Thib peb, qhov tseem ceeb ntawm tus naj npawb shading thiab lwm yam circuits.shading tooj yog hais txog ntau npaum li cas ADF tuaj yeem lim lub teeb, qhov loj dua tus naj npawb shading, qhov me dua qhov kev xa tawm ntawmADF, raws li kev xav tau ntawm cov vuam sib txawv, xaiv cov shading tus naj npawb, tuaj yeem tso cai rau tus welder kom muaj kev pom zoo thaum ua haujlwm, tuaj yeem pom qhov vuam taw tes thiab xyuas kom muaj kev nplij siab zoo dua, yog qhov tsim nyog rau kev txhim kho vuam zoo. Tus naj npawb shading yog ib qho tseem ceeb hauv kev qhia hauv ADF, raws li kev sib txuas lus ntawm qhov sib kis ntawm ADF thiab tus naj npawb shading nyob rau hauv lub teb chaws tus qauv rau vuam qhov muag tiv thaiv, pom lub teeb, ultraviolet thiab infrared kis ratio ntawm txhua shading tooj yuav tsum tau raws li qhov yuav tsum tau ntawm tus qauv.
Ua ntej, Lub vuam lim siv cov kua siv lead ua kuateebvalve npe LCD Vuam Lim, hu ua ADF; Nws cov txheej txheem ua haujlwm yog: lub teeb liab arc thaum soldering lub arc hloov mus rau hauv micro-ampere tam sim no teeb liab los ntawm photosensitive absorber raj, hloov los ntawm cov sampling resistor mus rau ib tug voltage teeb liab, ua ke los ntawm capacitance, tshem tawm cov DC tivthaiv nyob rau hauv lub arc, thiab ces amplifies lub voltage teeb liab los ntawm lub lag luam amplification Circuit Court, thiab lub amplified Circuit Court uas tsis tshua muaj kev tswj cov teeb liab yog xaiv los ntawm kev hloov dua siab tshiab. lim Circuit Court kom muab cov lus txib tsav mus rau LCD tsav Circuit Court. Lub LCD tsav Circuit Court hloov lub teeb lub teeb los ntawm lub teeb ci mus rau lub xeev tsaus, thiaj li zam kev puas tsuaj ntawm lub teeb arc rau lub qhov muag welder. Qhov hluav taws xob txog li 48V ua rau cov kua siv lead ua kua dub tam sim ntawd, thiab tom qab ntawd kaw qhov hluav taws xob siab nyob rau lub sijhawm luv luv, kom tsis txhob muaj qhov hluav taws xob siab txuas ntxiv mus rau cov kua siv lead ua kua, ua rau cov kua siv lead ua kua ua kua, thiab ua kom muaj zog siv zog. Lub DC voltage nyob rau hauv cov kua siv lead ua kua tsav Circuit Court, nws cov zis yog proportional rau lub luag hauj lwm voj voog, tsav lub kua siv lead ua lub teeb valve mus ua hauj lwm.
Plaub, kev sib txuas ntawm cov kua siv lead ua kua ua ke. ADF lub qhov rais yog tsim los ntawm cov iav coated, ob daim ua kua siv lead ua lub teeb lub teeb thiab ib daim iav tiv thaiv (saib daim duab 2), lawv txhua tus yog cov khoom siv iav, yooj yim tawg, yog tias daim ntawv cog lus ntawm lawv tsis ruaj khov, ib zaug cov welding solute splashes rau hauv cov kua siv lead ua kua ua ke, nws yuav ua rau cov kua siv lead ua kua sib xyaw ua ke kom tawg, yuav ua rau lub qhov muag ntawm cov khoom siv iav, yog li ntawd, cov ntaub ntawv tseem ceeb ntawm kev sib txuas ntawm cov khoom siv hluav taws xob yuav ua rau cov kua siv lead ua kua ua ke. lub ADF. Tom qab ntau qhov kev ntsuam xyuas, kev siv cov kua nplaum txawv teb chaws A, B ob qho tib si, raws li 3: 2 piv txoj hauv kev hauv lub tshuab nqus tsev tom qab nplawm, hauv 100-theem purification ib puag ncig siv lub tshuab gluing tsis siv neeg rau kev xa tawm thiab kev sib txuas, kom ntseeg tau tias cov yam ntxwv kho qhov muag ntawm ADF kua siv lead ua kua ua ke rau en379-2003 thiab nws cov txheej txheem muaj feem xyuam nrog kev sib koom ua ke, los daws cov txheej txheem sib xyaw ua ke.
