1. Yuav ua li cas siv hluav taws xob soldering hlau
Txoj kev tuav rov qab yog siv tsib ntiv tes los tuav tus tuav ntawm cov hlau nplaum hauv xib teg. Txoj kev no yog tsim rau high-power hluav taws xob soldering hlau, thiab vuam qhov chaw nrog loj tshav kub dissipation. Nyob rau hauv txoj kev zoo tuav, hluav taws xob soldering hlau siv nyob rau hauv txoj kev no kuj tseem loj, thiab lub ntsis ntawm lub soldering hlau yog zoo li tus. Tus cwj mem tuav txoj kev, txoj kev no yog qhov tsim nyog rau cov khoom siv hluav taws xob uas tsis tshua muaj hluav taws xob, vuam qhov chaw nrog cov cua sov me me, xws li vuam xov tooj cua, TV luam tawm Circuit Court boards thiab lawv cov txij nkawm.
Qhov thib ob, cov kauj ruam tshwj xeeb ntawm kev siv hluav taws xob soldering hlau
Preheating: Lub hau ntawm cov hlau soldering yog nyob ntawm 45-degree kaum sab xis, tiv thaiv lub ncoo thiab cov ko taw. Preheat tivthaiv pins thiab pads. Lub taub hau ntawm lub taub hau ntawm lub taub hau yuav tsum tsis txhob sawv ntawm qhov chaw tsis muaj tooj liab ntawm PCB lub rooj tsavxwm, uas tuaj yeem hlawv lub rooj tsavxwm rau hauv ib qho kab; Lub taub hau hlau yuav tsum zoo dua ua raws li cov kev taw qhia ntawm txoj kab: lub taub hau ntawm lub taub hau yuav tsum tsis txhob ntsaws ntawm lub qhov: lub sij hawm preheating yog 1 mus rau 2 vib nas this.
Tinning: Qhia cov tin hlau los ntawm kev sib cuag ntawm ko taw thiab cov hlau soldering; thaum lub tin hlau yog melted, master lub hlau noj ceev; thaum lub tin tau tawg rau tag nrho lub ncoo, qhib lub tin hlau; Tiv thaiv cov flux los ntawm kub kub; tag nrho tinning lub sij hawm yog hais txog 1 mus rau 2 vib nas this.
Qhib tin hlau: snoring tin hlau, lub cub tawg txuas ntxiv ntawm lub ncoo; lub sij hawm yog li ntawm 1 mus rau 2 vib nas this.
Tshem cov hlau soldering: Thaum tsuas yog cov pa taws me ntsis ntawm lub solder tawm, tua cov hlau soldering: cov pob qij txha yog solidified.
