Kev tsom xam ntawm cov nyhuv txias ntawm hluav taws xob soldering hlau txuas nrog diodes
Lub hom phiaj ntawm serializing diodes yog los txo qhov voltage thiab daws qhov teeb meem ntawm kub soldering hlau. Hauv qab no yog ib qho kev ntsuam xyuas seb puas serializing diodes tuaj yeem ua tiav lub hom phiaj ntawm kev txias.
Lub DC fais fab mov ncaj qha muab lub zog rau cov hlau soldering, tab sis yog tias tsis muaj qhov sib ntxiv ntawm qhov ntsuas kub thiab kev tswj xyuas Circuit Court, qhov kub tsis tuaj yeem khaws cia tas li thiab yuav txawv nrog thaj chaw vuam. Yog tias qhov kub thiab txias qis dhau lawm, nws yuav ua rau qeeb tin melting ceev, thaum yog tias qhov kub siab dhau lawm, nws yuav ua rau lub taub hau hlau oxidize sai heev thiab tiv thaiv tin los ntawm kev siv. Txoj hauv kev zoo tshaj los daws qhov teeb meem ntawm qhov ntsuas kub tsis tu ncua yog ntxiv ntsuas qhov ntsuas kub thiab tswj cov circuits. Yog hais tias lub tshuab hluav taws xob tsis tu ncua yog siv rau kev hloov kho, vim tias cov hlau soldering nws tus kheej tsis muaj qhov ntsuas qhov ntsuas kub, nws tsis tuaj yeem hloov mus rau qhov ntsuas kub thiab tsuas yog tuaj yeem txias los ntawm kev txo qhov siab.
Rau cov diodes zoo tib yam, nyob ntawm tus qauv, lub zog rau pem hauv ntej poob ntawm qhov qub rectifier diodes feem ntau nyob ib ncig ntawm {{0}}.7V, thaum lub zog pem hauv ntej poob ntawm Schottky diodes tseem qis dua. Yog hais tias cov hlau soldering yog siv los ntawm lub zog zaus AC lub zog, lub diode series tuaj yeem muaj qhov txo qhov hluav taws xob, vim tias lub zog AC raug kho los ntawm diode ib nrab nthwv dej, thiab cov nqi hluav taws xob zoo raug txo los ntawm ib nrab. Txawm li cas los xij, rau DC voltage, qhov zoo tshaj plaws voltage poob ntawm lub diode tsuas yog 0.7V, thiab amplitude ntawm voltage txo yog tsawg heev, uas tsis muaj qhov tseem ceeb ntawm qhov kub thiab txias.
Txhawm rau txo qhov kub thiab txias, tib txoj kev yog los ntawm kev txo qhov voltage. Muaj ob txoj hauv kev los txo qhov voltage. Ib qho yog los hloov qhov kev siv hluav taws xob ntawm qhov piv txwv ntawm cov khoom siv hluav taws xob sab hauv qhov hluav taws xob ntawm lub charger, uas yuav tsum muaj qee qhov kev paub hauv Circuit Court thiab lub hauv paus. Lwm txoj hauv kev yog siv cov khoom tiav DC adjustable kauj ruam-down module, uas hloov cov zis hluav taws xob los ntawm qhov sib txawv ntawm cov resistor. Thiab nws tuaj yeem hloov kho kom txias cia, thiab cov khoom kuaj xyuas tuaj yeem muab ntxiv rau hauv cov hlau thav duab. Tom qab cov hlau nplaum tau muab tso rau, qhov hluav taws xob tuaj yeem txo qis.
Yog li, siv cov diode series kom txias tsis zoo rau qhov kawg tshwm sim vim yog qhov me me ntawm qhov txo qhov voltage.
