Yuav kom ua tau li ntawd, raus twb rhuab soldering ammonium chloride hmoov los yog raws li rosin, uas nyob rau hauv lem yuav tshem nws los ntawm qhov xaiv hlau oxidants thiab cuag cov kev pab cuam lub neej. Nws yuav tsum tau ceev faj heev, raws li kub soldering hlau muaj peev xwm heev yooj yim ua rau ib tug tua hluav taws thiab los ntawm no tsis muaj ib tug muaj kev ruaj ntseg.
• Solder yog ib tug mix ntawm ib tug loj tus naj npawb ntawm cov uas tsis muaj-melting co uas yog melted ntawm ib tug me ntsis cov cua kub thiab pab raws li ib tug nplaum, uas yog soldered nrees tuav ib sab. solder zoo yog tsis tsau, thiab yog li ntawd, tej zaum nws yuav zoo tau dab tsi xws li los ntawm nplooj thiab xaus nrog rawg. Nrog rov siv cov tshuaj lo nws yuav siv sij hawm rau hauv daim ntawv ntawm ib tug shapeless pob, uas, nyob rau hauv lem, ua rau nws yooj yim mus siv nws raws li ib tug cua sov yuav siv sij hawm ib tug ntev lub sij hawm. Nyob rau hauv thiaj li yuav zam tau qhov no, nws yog txaus rau txiav tawm ib tug me me piece. Wb to taub yuav ua li cas solder: Peb kov ib tug kub soldering hlau los solder, thiab tos kom txog thaum nws puv, ces nws yuav tsum sib sau ua ke nyob rau ntxeev ntawm lub soldering hlau thiab obvoloch nws. Maj mam obvolokshy nws captures tsawg kawg yog cov tshuaj lo thiab txav mus nws maj mam muab mus rau ib tug taw tes soldering ntawm qhov chaw, tom qab uas pluav tag nrho saum npoo. Ces rov ua lub lag luam no tau ntev li ntev raws li lub compound tsis tau ib tug ib lub zog los yog muab kaw tag nrho cov tsim nyog cheeb tsam. Qhov kawg ntawm solidification ntawm solder soldered mus so qhov chaw nrog ib tug phuam ntaub thiab tuav nws cheb nrog ib cov ntaub ntawv los yog ntwav txhuam ntoo. Thaum lub sij hawm tu koj yuav tsum tau sim ua kom qhov chaw raws li smooth ib tug ua tau.
• Yuav ua li cas solder cov nyob ntawm tej? Cov pub leejtwg mus rau qhov no yog heev yooj yooj yim soldering. Vim lub fact tias cov nyob ntawm tej yog heev nyias thiab raug kev puas tsuaj thiab yuav tsum tsis txhob yuav kho nrog ntau yam kev daws teeb meem xws li flux. Txaus yaj rosin nyob rau hauv ib tug me ntsis me me ntawm ethanol thiab no sib tov huv liab qab nyob ntawm tej tam sim ntawd ua ntej soldering.

Yog li ntawd koj paub yuav ua li cas solder, koj tau tam sim no xav txog koj tus kheej ib tug neeg cob nyob rau hauv daim teb no. Txawm li cas los, rau ib tug ua tiav kev paub ntawm cov txheej txheem no yuav tsum tau xyaum.
