Yog vim li cas siv rosin thaum lub sij hawm soldering nrog hluav taws xob soldering hlau
Rosin, ib hom soldering flux.
1. Lub taub hau ntawm cov hlau tsis yog xim hlau, thiab tom qab stained nrog rosin, nws yog ib qho yooj yim rau yaj lub tin thiab lo rau ntawm cov hlau soldering.
2. Qhov laj thawj yog vim li cas cov tin hlau yog ua kom nyias nyias yog vim nws yuav tsum tau yooj yim yaj, dipped nyob rau hauv rosin, thiab melted rau hauv ib puag ncig thiab tag nrho cov tee dej, es tsis khiav ncig.
3. Solder tee ncaj qha mus rau ntawm qhov sib koom ua ke. Yog tias qhov sib koom ua ke tsis tau ntxuav los yog oxidized, nws yooj yim rau kev sib cuag thiab poob yooj yim. Ntxiv rosin pab tshem tawm cov nyhuv tsis zoo ntawm oxidation, ua rau cov tawv nqaij muaj zog.
4. Yog tsis muaj solder, thaum lub soldering hlau raug tshem tawm ntawm lub solder sib koom, nws yog ib qho yooj yim rau lub solder lo, ua rau unsightly solder pob qij txha.
5. Kev xa ncaj qha mus rau nws qhia tau hais tias cov txheej txheem vuam tsis tas yuav tsum muaj kev xav tau siab lossis qhov dej ntws ntau dhau ua rau cov khoom tsis tsim nyog.
Rosin yog ib tug muaj zog txo tus neeg sawv cev uas yuav txo tau aluminium trioxide thiab tin lead oxide (ob qho tib si uas muaj ob lub xeev valence), tsim cov hlau sib xws thiab vuam slag. Feem ntau, nws yuav tsum tsis txhob kis kab mob.
Lub taub hau ntawm lub taub hau hlau tsis tuav cov tin, thaum lub 60 tin rau 40 cov hlau lead solder muaj cov ntsiab lus melting ntau dua, thiab cov thermal conductivity ntawm ob hlau oxides thiab cov organic oxides tsim los ntawm rosin oxidation tsis zoo. Thaum lub tin hlau melts, nws tsis tuaj yeem tau txais cov cua kub txuas ntxiv thiab tsis tuaj yeem ntws mus rau hauv cov khoom.
Kuv tsis paub yuav ua li cas rau solder, txhob txwm oxidizing sab nraum qab ntawm lub taub hau ntawm soldering hlau kom lub sab pem hauv ntej noj tin thiab thaum kawg dripping yog ib txoj kev zoo. Lub tin hlau yog nyias nyias, thiab qhov zoo ntawm qhov thinnest ntawm cov tin hlau yog qhov tsis zoo, nrog cov dej ntws tsis zoo, thiab nws tsis tuaj yeem tsim pawg thiab drips. Nws raug nquahu kom hloov nws. Lub slag tin thiab khib nyiab xyab tsis tuaj yeem soldered txhua.
Thaum kawg, tom qab lub pob tin poob rau ntawm cov hlau nto, tsis muaj sij hawm rau cov khoom-kua fusion, thiab qhov chaw sib cuag yog xoob thiab tsis ruaj khov, ua rau nws tsis tshua muaj siab rau cov khoom cuav.
Nws raug nquahu kom siv rab phom cua lossis cov txheej txheem hais saum toj no.
