Soldering hlau tinning txoj kev ua haujlwm

Npaj ib daim ntawm cov ntawv xuab zeb zoo, tom qab ntawd maj mam txhuam lub hau ntawm cov hlau soldering, ua kom sov nrog hluav taws xob, dipped lub taub hau ntawm cov hlau soldering hauv rosin, kov cov hlau nplaum nrog cov hniav saum npoo, thiab yaj lub solder rau lub hau. ntawm cov hlau soldering kom tiav cov haujlwm tinning.

Yog hais tias lub qub soldering hlau taub yog heev oxidized los yog muaj txawv teb chaws teeb meem nrog rau saum npoo, nws yuav tsum tau khob tawm nrog ib tug steel rauj kom nthuav tawm cov xim hlau rau ntawm qhov chaw, thiab ces rov tinned.

Cov kauj ruam yooj yim ntawm vuam
1. Txhawm rau ua kom cov pob qij txha muaj cov khoom siv zoo, ua ntej polish lub hau ntawm cov hlau nplaum nrog cov ntawv xuab zeb. Ceev faj tsis txhob hnav lub hau ntawm cov hlau soldering ntau dhau. Kev hnav ntau dhau yog yooj yim rau oxidized.

2. Qhib lub tshuab hluav taws xob thiab ua kom sov. Thaum qhov kub thiab txias tuaj yeem yaj lub solder, thov cov flux mus rau qhov kawg ntawm cov hlau soldering, thiab tom qab ntawd siv lub solder sib npaug ntawm qhov kawg ntawm cov hlau soldering.

3. Kov qhov sib koom ua ke nrog lub hau ntawm cov hlau soldering. Thaum lub solder yog immersed nyob rau hauv lub solder sib koom, maj mam rub lub soldering hlau.

4. Tom qab ua tiav lawm, tua hluav taws xob soldering hlau thiab muab tso rau ntawm cov hlau soldering. Ceev faj kom tsis txhob raug kub hnyiab los ntawm cov cua sov seem.

5. Cov dej ntws seem ntawm lub rooj tsav xwm hauv Circuit Court tuaj yeem ntxuav nrog cawv kom tsis txhob muaj cov pa roj carbonized los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lub voj voog.

Txoj kev txij nkawm ntawm cov hluav taws xob soldering hlau uas tsis kub tom qab tau energized, txoj kev kho ntawm lub taub hau soldering hlau nrog hluav taws xob

1. Thaum cov hlau nplaum muaj zog, lub hau ntawm cov hlau soldering tsis kub, feem ntau yog vim lub hwj chim qaum poob los yog cov tub ntxhais hlau ntawm cov hlau soldering yog tawg.

Txoj kev tu: Siv R × lkn iav ntawm multimeter los ntsuas ob qhov kawg ntawm lub hwj chim ntsaws. Yog hais tias tus pointer ntawm lub multimeter tsis txav, nws txhais tau hais tias muaj ib tug qhib Circuit Court txhaum.

2. Ua ntej txheeb xyuas seb cov hlau lead hlau ntawm lub ntsaws nws tus kheej yog qhov tshwm sim ntawm qhov qhib Circuit Court, yog tias tsis yog, koj tuaj yeem tshem tawm tus kov Bakelite, thiab tom qab ntawd siv multimeter los ntsuas ob txoj hauv kev ntawm cov tub ntxhais hlau soldering, yog tias tus pointer ntawm multimeter tseem tsis txav, nws txhais tau hais tias cov tub ntxhais hlau soldering puas lawm, thiab cov tub ntxhais hlau yuav tsum tau hloov.

3. Qhov kev tiv thaiv ntawm ob qho tib si ntawm 35W sab hauv cov cua sov soldering hlau tub ntxhais yog hais txog 1.Skfl. Yog hais tias qhov ntsuas tsis kam yog qhov qub, nws txhais tau hais tias cov tub ntxhais hlau soldering zoo. Qhov txhaum tshwm sim nyob rau hauv lub hwj chim lead hlau thiab lub plug nws tus kheej. Feem ntau cov faults yog txhuas hlau breakout.

Txoj kev tu: Hloov cov tub ntxhais hlau soldering, ntxig ib tug tshiab soldering hlau tub ntxhais ntawm tib yam specification rau hauv lub connecting pas nrig, txhim kho cov hlau lead hlau ntawm lub fixing ntsia hlau, thiab zawm lub davhlau ya nyob twg ncej. Nyob rau tib lub sijhawm, them sai sai rau txiav tawm qhov dhau ntawm cov tub ntxhais hlau soldering hlau los tiv thaiv ob Lead shorted.
