Kev kho mob kub hnyiab los ntawm hluav taws xob soldering hlau
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 tsim cov tshuaj tiv thaiv, tooj liab raug txo dua, thiab ethanol tsis muaj corrosive rau cov soldering hlau taub.
Soldering hlau pre-soldering kev kho mob
Ua ntej soldering, kev kho mob ua ntej yuav tsum tau ua ntawm cov khoom siv pins lossis cov khoom siv ntawm lub rooj sib tham.
1. Tshem tawm cov oxide txheej ntawm qhov vuam
Ib rab riam tuaj yeem ua los ntawm cov hniav tawg. Tshem tawm cov oxide txheej ntawm cov hlau ua kom nthuav tawm cov hlau nplaum ntawm cov hlau lead.
Lub rooj tsav xwm luam tawm tuaj yeem polished nrog cov ntaub nplaum zoo, thiab tom qab ntawd coated nrog ib txheej ntawm rosin cawv tov.
2. Cov khoom siv tin plating
Tin on scraped leads. Tom qab dipping cov hlau lead hauv cov tshuaj rosin cawv, nias lub hau ntawm cov hlau kub kub nrog cov tin ntawm cov hlau lead thiab tig cov hlau lead. Cov txhuas tuaj yeem sib npaug plated nrog ib txheej nyias ntawm tin. Ua ntej cov hlau yog welded, lub rwb thaiv tsev sheath yuav tsum tau tev tawm, thiab tom qab ntawd cov saum toj no ob txoj kev kho yuav ua tau ua ntej formal welding. Nyob rau hauv cov ntaub ntawv ntawm multi-strand xov hlau, lawv yuav tsum tau twisted ua ke tom qab polishing, thiab ces tinned.
