hlawv los ntawm hluav taws xob soldering hlau raug kho
Lub npe hu ua hluav taws xob soldering hlau hlawv kom tuag txhais tau hais tias cov hlau tsis tuaj yeem txuas nrog lub tin, vim tias qhov kub ntawm cov hlau taub hau yog siab dhau thiab qhov saum npoo yog oxidized heev. Feem ntau muaj ob txoj hauv kev los tiv thaiv qhov tshwm sim ntawm qhov kub hnyiab:
1. Cov khoom siv hluav taws xob sib txuas: Hauv cov txheej txheem ntawm kev sib txuas, ib zaug cov hlau kub kub nce mus txog, lub zog hluav taws xob tuaj yeem raug txiav tawm kom tsis txhob overheating thiab oxidation.
2. Txoj kev ua kom txias: siv lub tshuab ua kom txias.
Pov tseg tom qab hlawv
1. Siv rab riam los dai cov oxide txheej rau ntawm qhov chaw.
2. Muab cov oxidized tooj liab tso rau hauv ib lub thawv ntim nrog ethanol (1-2min), vim tias tom qab cov tooj liab oxide thiab ethanol tau ua kom sov los ua cov tshuaj tiv thaiv, tooj liab raug txo dua, thiab ethanol tsis muaj corrosive rau cov soldering hlau taub.
