Yuav ua li cas thaum muaj xwm ceev solder xov hlau tsis muaj hlau soldering
Yuav ua li cas solder hlau tsis muaj hlau? Txoj kev yooj yim tshaj plaws yog hlawv lawv nrog lub teeb. Kuv tseem nco qab tias kuv nyiam ua si nrog electronics thaum kuv tseem yog menyuam yaus. Nyob rau lub sijhawm ntawd tsis muaj cov hlau nplaum, yog li peb yuav tsum siv lub teeb ci hauv tsev los hlawv cov xov hlau.
Siv cov hlau strippers los tev tawm ob lub xov hlau kom nthuav tawm ib feem ntawm cov tooj liab, tom qab ntawd ntswj ob lub xov hlau ua ke, qhwv ib lub xov hlau nyias nyias nyob ib ncig ntawm cov xov hlau uas sib tw, tshem tawm cov sib dua, thiab hlawv cov hlau ntawd! Nco ntsoov siv hluav taws xob insulating daim kab xev los tiv thaiv hluav taws xob poob siab.
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 puas degrees, uas yog tsis muaj teeb meem nyob rau hauv tag nrho cov.
Lwm txoj hauv kev yog siv cov hlua hlau los yog cov hlau nyias nyias los yog tooj liab (feem ntau cov lus qhia hlau yog ua los ntawm tooj liab, thiab qee qhov siv alloys) kom sov rau lawv liab thiab ces welding lawv. Thaum kuv tseem yog menyuam yaus, muaj ib lub qhov cub hluav taws kub hnyiab hauv tsev. Lub sijhawm ntawd, cov nplaim hluav taws tau siv los hlawv cov thee liab hauv qhov cub. Qhov no kuj tseem siv tau los ua cov xov hlau. Qhov no feem ntau ua thaum kuv tseem yog menyuam yaus.
Yog tias koj cov xwm txheej zoo, koj tuaj yeem yuav cov tin slurry, uas tseem siv tau yooj yim dua, tab sis feem ntau nws yog siv rau kev cog qoob loo ntawm cov xov tooj ntawm tes. Koj tsuas yog yuav tsum tau siv cov tin slurry rau qhov sib tw ntawm cov xov hlau thiab hlawv nws nrog lub teeb, lossis Lub tshuab ziab plaub hau muaj zog tuaj yeem tshuab tawm. Ceev faj tsis txhob hnov qab siv hluav taws xob insulating daim kab xev.
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 siv tsis txwv!
