Yog vim li cas siv rosin thaum soldering hlau
1. Lub taub hau ntawm cov hlau tsis lo rau tin. Tom qab dipping hauv rosin, nws yog ib qho yooj yim rau yaj lub tin thiab lo rau cov hlau soldering.
2. Cov tin hlau yog ua kom nyias nyias vim nws yooj yim rau yaj thiab stained nrog rosin, yog li ntawd cov tin hlau nyias tuaj yeem yaj mus rau hauv ib puag ncig thiab tag nrho cov duab poob es tsis txhob khiav ncig.
3. Lub solder yog ncaj qha dripped rau ntawm cov pob qij txha. Yog tias cov pob qij txha raug ntxuav los yog oxidized, nws yooj yim kom xoob thiab poob tawm thaum kov. Ntxiv rosin tau txais txiaj ntsig los tshem tawm cov txiaj ntsig tsis zoo ntawm oxidation, ua rau lub zog muaj zog.
4. Yog tsis muaj solder, nws yog ib qho yooj yim los lo rau solder thaum lub soldering hlau raug tshem tawm los ntawm lub solder sib koom, uas ua rau unsightly solder pob qij txha.
5. Muab pov tseg ncaj qha, qhia tias cov txheej txheem yuav tsum tsis txhob siab thaum vuam, lossis muaj dej ntau dhau, ua rau cov khoom pov tseg tsis tsim nyog.
Rosin yog ib tug muaj zog txo tus neeg sawv cev uas yuav txo tau aluminium oxide thiab tin-lead oxides (ob leeg txhuas thiab tin muaj ob oxides sib xws rau ob lub xeev valence) los tsim cov hlau sib xws thiab vuam slag, uas yuav tsum tsis txhob stained ib txwm. solder.
Lub taub hau ntawm cov hlau soldering tsis nyob hauv tin, tab sis lub melting point ntawm 60 tin -40 lead solder yog qhov siab. Tsis hais cov hlau oxide lossis cov organic oxide tsim los ntawm oxidation ntawm rosin muaj cov thermal conductivity tsis zoo. nqes.
Kuv tsis paub yuav ua li cas rau solder, nws yog ib txoj hauv kev zoo rau txhob txwm oxidize sab nraum qab ntawm lub taub hau soldering, kom pem hauv ntej yuav mus noj tin thiab thaum kawg drip. Lub tin hlau yog nyias heev. Lub thinnest tin hlau yog qhov tsis zoo thiab muaj qhov dej tsis zoo.
Thaum kawg, tom qab cov khoom siv tau poob rau hauv cov hlau nto, tsis muaj sij hawm rau cov khoom siv-kua fusion, qhov chaw sib cuag yog xoob thiab tsis ruaj khov, thiab nws yooj yim heev rau solder.
