Yuav ua li cas siv ib tug soldering hlau - kev npaj
1. Ua ntej yuav siv ib tug tshiab soldering hlau, polish lub taub hau nrog zoo sandpaper, sov nws nrog hluav taws xob, dipped nyob rau hauv rosin thiab kov cov hniav ntawm lub ntsis mus rau lub soldering hlau kom lub taub hau yog tusyees coated nrog tin, uas yooj yim soldering thiab soldering. Tiv thaiv oxidation ntawm cov hlau taub hau nto. Yog hais tias lub qub soldering hlau taub yog hnyav oxidized thiab tig dub, koj tuaj yeem siv cov ntawv hlau los tshem tawm cov oxide saum npoo kom nthuav tawm cov xim hlau nplaum thiab rov ua cov tin plating ua ntej siv.
Cov hlau nplaum yuav tsum muaj 220V AC fais fab mov, yog li ua tib zoo saib xyuas kev nyab xeeb thaum siv nws. Cov ntsiab lus hauv qab no yuav tsum ua tib zoo ua:
Nws yog qhov zoo tshaj plaws los siv peb-ncej ntsaws rau lub vuam hlau ntsaws, thiab lub plhaub yuav tsum tau ua kom zoo.
Ua ntej siv, ua tib zoo xyuas seb lub hwj chim ntsaws thiab lub hwj chim qaum puas puas lawm, thiab xyuas seb lub taub hau hlau puas xoob.
Thaum siv cov hlau nplaum, tsis txhob tsoo nws nyuaj thiab tiv thaiv kom tsis txhob poob. Yog hais tias muaj solder ntau dhau ntawm lub taub hau hlau, so nws nrog ib daim ntaub. Tsis txhob muab pov tseg kom tsis txhob scalding lwm tus.
Thaum lub sij hawm welding txheej txheem, lub soldering hlau yuav tsum tsis txhob muab tso dag nyob ib ncig ntawm. Thaum tsis welding, nws yuav tsum tau muab tso rau ntawm soldering hlau sawv ntsug. Nco ntsoov tias cov hlua hluav taws xob tsis tuaj yeem muab tso rau ntawm lub taub hau ntawm lub taub hau los tiv thaiv cov txheej txheem rwb thaiv tsev los ntawm kev kub hnyiab thiab ua rau muaj kev sib tsoo.
Tom qab siv, cov khoom siv hluav taws xob yuav tsum raug txiav tam sim ntawd, tshem tawm lub hwj chim ntsaws thiab txias ua ntej muab cov hlau nplaum rov qab rau hauv lub thawv khoom.
2. Solder thiab flux
Thaum vuam, solder thiab flux kuj tseem xav tau.
Solder: Thaum vuam cov khoom siv hluav taws xob, feem ntau siv cov hlau nplaum nrog cov rosin core. Cov hlau nplaum no muaj qhov qis qis thiab muaj cov rosin flux, ua rau nws yooj yim heev rau siv.
Flux: Feem ntau siv flux yog rosin lossis rosin dej (solve rosin hauv cawv). Kev siv flux tuaj yeem pab tshem tawm cov oxides ntawm cov hlau saum npoo, uas yog qhov zoo rau kev vuam thiab tiv thaiv lub taub hau hlau. Solder paste kuj tseem siv tau thaum vuam cov khoom loj lossis cov xov hlau, tab sis nws yog corrosive thiab cov seem yuav tsum tau muab tshem tawm hauv lub sijhawm tom qab vuam.
3. Cov cuab yeej pabcuam
Txhawm rau kom yooj yim rau kev ua haujlwm vuam, rab koob-qhov ntswg pliers, offset pliers, tweezers, thiab riam feem ntau yog siv los ua cov cuab yeej pabcuam. Koj yuav tsum kawm siv cov cuab yeej no kom raug. Koob ntswg pliers, offset pliers, tweezers, riam.
Yuav ua li cas siv cov hlau soldering - kev kho mob ua ntej
Ua ntej welding, cov khoom siv pins los yog vuam qhov chaw ntawm lub rooj tsavxwm Circuit Court yuav tsum tau pre-soldered:
Tshem tawm oxide txheej los ntawm vuam qhov chaw
Ib rab riam tuaj yeem ua los ntawm cov saw hlau tawg kom khawb tawm cov oxide txheej ntawm cov hlau ua kom pom cov hlau nplaum ntawm tus pin.
