Taw qhia rau Soldering Technology nrog Soldering Hlau
Cov txheej txheem soldering hais txog ntawm no yog hais txog kev sib xyaw ntawm cov hlau conductor thiab solder, uas yog feem ntau siv hauv kev tsim hluav taws xob circuits. Solder yog cov hlau lead-tin alloy nrog lub melting point ntawm txog 183 degrees. Cov khoom lag luam muag muag feem ntau ua rau hauv ib lub sawb lossis xaim, qee qhov solder kuj muaj rosin, yooj yim dua rau siv.
1, tuav txoj kev ntawm soldering hlau
Feem ntau tuav cov txheej txheem soldering hlau ntawm cwj mem thiab nrig txoj kev.
(1), tuav tus cwj mem txoj kev. Haum rau lub teeb hom soldering hlau xws li 30W endothermic. Nws lub taub hau hlau yog ncaj, lub taub hau kawg tau muab tso rau hauv ib qho beveled los yog conical, haum rau vuam ib qho me me ntawm lub ncoo.
(2), Ntiv txoj kev. Haum rau ntau zog soldering hlau, peb ua hluav taws xob ntau lawm feem ntau tsis siv high-power soldering hlau (tsis qhia ntawm no).
2, nyob rau hauv cov luam ntawv Circuit Court board soldering ua rau ntau txoj kev.
Cov ntawv luam tawm Circuit Board tau muab faib ua ib sab thiab ob sab 2 hom. Los ntawm-qhov ntawm nws, feem ntau tsis yog-metallized, tab sis nyob rau hauv thiaj li yuav ua rau cov khoom welded rau lub Circuit Court board yog ntau ruaj thiab txhim khu kev qha, tam sim no cov luam Circuit Court board ntawm hluav taws xob cov khoom los ntawm lub qhov feem ntau siv metalized. Yuav coj
Hlau soldered rau ib qho yooj yim ib-vaj huam sib luag txoj kev:
(1), ncaj nraim ntawm lub taub hau txiav. Ua ncaj qha los ntawm lub qhov, vuam kom qhov tsim nyog tus nqi ntawm melted solder nyob rau hauv lub ncoo saum toj no lub uniformly surrounded los ntawm tinned leads, tsim ib lub khob hliav qab pwm, kom txias thiab solidified, feem ntau ntawm cov hlau lead txiav tawm. (Saib lub rooj tsavxwm rau cov txheej txheem tshwj xeeb)
(2), ncaj qha faus. Los ntawm kev hla-qhov ntawm cov hlau lead tsuas yog qhov tsim nyog ntev, lub melted solder mus rau lub taub hau txhuas faus rau hauv cov pob qij txha.
nto. Hom kev sib koom ua ke no kwv yees ib hemisphere, thiab txawm hais tias nws yog qhov zoo nkauj, yuav tsum tau them nyiaj tshwj xeeb rau kev tiv thaiv qhov tsis tseeb.
3 los tiv thaiv tsis zoo soldering
Vuam tshuab yog cov neeg nyiam xov tooj cua yuav tsum paub cov thev naus laus zis yooj yim, xav tau kev xyaum ntxiv kom paub.
1, xaiv txoj cai solder, yuav tsum tau siv los vuam cov khoom siv hluav taws xob uas tsis tshua muaj melting point solder hlau.
2, flux, nrog 25% rosin yaj hauv 75% cawv (qhov hnyav piv) raws li flux.
3, soldering hlau yuav tsum tau siv ua ntej lub tin, txoj kev tshwj xeeb yog: lub soldering hlau yuav kub, yuav tsum tau tsuas yog yaj lub solder, coated nrog flux, thiab ces sib npaug zos coated nrog solder nyob rau hauv lub soldering hlau taub hau, yog li ntawd. lub taub hau ntawm hlau uniformly noj ib txheej ntawm tin.
4, welding txoj kev, lub ncoo thiab tivthaiv pins nrog zoo sandpaper polished huv si, coated nrog flux. Nrog rau cov ntsiab lus ntawm cov hlau soldering dipped nyob rau hauv qhov tsim nyog tus nqi ntawm solder, hu rau lub soldering point, yuav tsum tau soldered nyob rau hauv lub soldering point ntawm tag nrho cov melted thiab submerged Cheebtsam ua lub taub hau, soldering hlau taub hau nyob rau hauv lub tivthaiv pins maj mam tuaj tos, tawm lub soldering. taw tes.
5, lub sijhawm vuam yuav tsum tsis txhob ntev dhau, txwv tsis pub nws yooj yim rau hlawv cov khoom, yog tias tsim nyog, tweezers tuaj yeem siv los txiav tus pin los pab kom cov cua sov.
6, qhov sib koom ua ke yuav tsum yog sinusoidal yoj lub ncov zoo li, qhov saum npoo yuav tsum ci thiab sib npaug, tsis muaj tin spines, tin npaum li cas.
7, tom qab ua tiav ntawm vuam, siv dej cawv los ntxuav lub rooj tsav xwm hauv Circuit Court ntawm cov seem flux, txhawm rau tiv thaiv cov roj carbonization ntawm cov flux cuam tshuam rau kev ua haujlwm ntawm lub voj voog.
8, integrated circuits yuav tsum yog qhov kawg vuam, soldering hlau yuav tsum tau cia siab rau hauv av, los yog lub hwj chim tawm tom qab siv cov residual tshav kub welding. Los yog siv lub qhov (socket) tshwj xeeb rau kev sib xyaw ua ke, txuas lub qhov (socket) thiab tom qab ntawd ntxig rau qhov sib xyaw ua ke.
9, soldering hlau yuav tsum tau muab tso rau ntawm soldering hlau sawv.
