Qhov ua rau hluav taws xob soldering hlau to thiab yuav ua li cas nrog nws
Cov soldering hlau tub ntxhais yog tsim los ntawm cov hluav taws xob cua kub xaim hluav taws xob, ib qho rwb thaiv tsev etcet, thiab ib txheej txheej txheej. Thaum rwb thaiv tsev txheej yog qhov ntub dej dhau los yog cov hnub nyoog ntev dhau, lub rwb thaiv tsev kawm ntawv yuav txo qis, ua rau cov tub ntxhais xyaum ua kom tsis txhob muaj. Tom qab ntawd nws kis tau los ntawm kev hloov pauv kub hloov thiab soldering hlau ntxeev ntawm cov hluav taws xob solding hlau.
Tus kov ntawm cov hluav taws xob tshuab hluav taws xob tuaj yeem ua tau kev ua txhaum kev ua txhaum tom qab kev ua haujlwm tshwj xeeb.
Tom qab cov hluav taws xob tshuab hluav taws xob hlau leaks hluav taws xob, qhov teeb meem yog loj heev thiab tuaj yeem yooj yim ua rau cov neeg thiab hluav taws xob thiab hluav taws xob yuav raug kho. Thov hloov cov soldering hlau tub ntxhais thiab xau cov khoom siv tam sim ntawd, thiab yog tias tsim nyog, hloov lawv tag nrho.
Yuav Ua Li Cas Thiaj Haum Nrog Hluav Taws Xob Toldering Hlau Xau
1. Ua ntej ua ntej, kho cov multimeter ntau rau gat voltage hom. Txuas cov kev sojntsuam dub rau hauv av thiab cov kev sojntsuam liab mus rau qhov ntxeev ntawm cov hlau soldering. Saib seb puas muaj kev sib txuam. Yog tias muaj kev nyeem ntawv, nws qhia tias cov hlau soldering yog xaub hluav taws xob thiab xav tau kho.
2. Txhaum cov hlau soldering thiab nrhiav cov cim hauv av hauv av. Tom qab ntawd, ua raws li cov xaim xaim hauv av kom pom tus resistor txuas nrog cov Circuit Coffe thiab ntsuas nws tus nqi tiv thaiv kev tiv taus. Yog tias nws tshaj 5 ohms, nws raug txiav txim raws li kub hnyiab thiab xav tau hloov (feem ntau, lub resistor no vim li cas vim tias xau dej). Yog tias tus nqi tiv thaiv tsis tuaj yeem yog ib txwm, thov paub meej tias cov hlau plug muaj kev sib cuag.
3. Tshem tawm cov burnt resistor thiab hloov nws nrog ib qho tshiab. Nco ntsoov tias qhov ua tsis kam ntawm no resistor yog 0 ohms, nws pab lub hom phiaj tiv thaiv. Tsis txhob luv-Circuit thaj tsam no!

6. Tomqab kho tau tiav, siv ntau ntxiv kom paub meej tias tus nqi tiv thaiv ntawm soldering hlau taub thiab hlau xaim. Yog tias tus nqi tiv thaiv tsis pub dhau 2 ohms, nws ua pov thawj tias kev kho tau zoo.
