Txoj kev ntawm kev kub ceev soldering tsis muaj hluav taws xob soldering hlau
Yuav ua li cas solder cov hlau xaus tsis muaj ib tug soldering hlau yog qhov yooj yim tshaj los hlawv lawv nrog ib tug sib zog. Kuv tseem nco qab tias kuv nyiam ua si nrog hluav taws xob thaum kuv tseem yog menyuam yaus. Thaum lub sij hawm ntawd, tsis muaj hluav taws xob soldering hlau, thiab cov hlau soldering tau hlawv nrog lub teeb nyob hauv tsev.
Siv cov hlua khi hlua khi ob lub xov hlau kom nthuav tawm ib feem ntawm cov hlau tooj liab, tom qab ntawd ntswj ob lub xov hlau ua ke, siv cov hlau nplaum nyias nyias los qhwv ib ncig ntawm cov xov hlau uas sib tw, tshem tawm cov sib dua, thiab hlawv cov hlau ntawd! Ua tib zoo siv cov kab hluav taws xob insulating los tiv thaiv hluav taws xob.
Koj tsis xav tau lub teeb. Yog tias koj muaj lub teeb cawv, koj tuaj yeem hlawv nws ncaj qha nrog lub teeb cawv. Lub melting point ntawm solder yog hais txog ob puas degrees, thiab cov cua kub ntawm cov cawv teeb yuav ncav cuag rau los yog xya degrees, uas yog tsis muaj teeb meem kiag li.
Tom qab ntawd muaj lwm txoj hauv kev, siv cov hlua hlau los yog nyias steel tuav los yog tooj liab (feem ntau cov lus qhia hlau yog ua los ntawm tooj liab, thiab qee qhov siv alloys) kom sov rau cov xim liab, thiab tom qab ntawd welding lawv. Thaum kuv tseem hluas, muaj ib lub qhov cub hluav taws kub kub hauv kuv lub tsev. Lub sijhawm ntawd, kuv siv cov taws kub hnyiab kub kub hauv qhov cub hluav taws kub. Qhov no kuj tseem siv tau rau vuam hlau. Kuv feem ntau ua qhov no thaum kuv tseem yog menyuam yaus.
Yog tias koj cov xwm txheej zoo, koj tuaj yeem yuav tin paste, uas kuj yooj yim rau siv, tab sis nws feem ntau yog siv rau tin cog cov xov tooj ntawm tes. Koj tsuas yog yuav tsum tau siv cov tin muab tshuaj txhuam rau qhov sib tw ntawm cov hlau thiab hlawv nws nrog lub teeb, lossis Lub tshuab ziab plaub hau muaj zog tuaj yeem tshuab nws. Ceev faj tsis txhob hnov qab siv hluav taws xob insulating daim kab xev rau kev ua haujlwm.
Nws raug nquahu kom siv hluav taws xob soldering hlau. Niaj hnub no, hluav taws xob soldering hlau tsis kim thiab pheej yig heev. Kuj tseem muaj 5V hluav taws xob soldering hlau. Txawm hais tias lub zog me me, lub sijhawm thov tsis txwv!
