Mastering thev naus laus zis ntawm hluav taws xob soldering hlau
Cov cuab yeej siv vuam tau hais los ntawm no yog hais txog kev sib xyaw ntawm cov hlau conductors thiab cov khoom siv feem ntau siv hauv kev tsim hluav taws xob hluav taws xob. Solder yog cov hlau lead-tin alloy nrog lub melting point ntawm kwv yees li 183 degrees. Solder nyob rau hauv kev ua lag luam feem ntau ua rau hauv ib daim hlab los yog filaments, thiab ib co solder kuj muaj rosin, ua rau nws yooj yim dua rau siv.
1. Txoj kev tuav lub tshuab hluav taws xob
Feem ntau muaj ob txoj hauv kev los tuav lub zog hluav taws xob: tus cwj mem tuav thiab lub nrig tuav.
(1) Cov txheej txheem tuav. Haum rau lub teeb yuag hlau xws li 30W sab hauv cua sov. Nws lub taub hau hlau yog ncaj nraim, thiab lub taub hau kawg yog xa mus rau hauv ib qho inclined los yog conical zoo, haum rau vuam me me solder pads.
(2) Fist tuav txheej txheem. Haum rau high-power soldering hlau, peb feem ntau tsis siv high-power soldering irons nyob rau hauv hluav taws xob manufacturing (tsis qhia ntawm no).
2. Muaj ntau txoj hauv kev rau soldering ua rau ntawm cov ntawv luam tawm hauv Circuit Court.
Printed circuit boards muab faib ua ob hom: ib sab thiab ob sab. Qhov los ntawm qhov ntawm nws feem ntau tsis yog xim hlau, tab sis txhawm rau ua kom cov khoom siv welded rau lub rooj tsavxwm Circuit Court muaj kev ruaj ntseg thiab txhim khu kev qha, feem ntau ntawm cov qhov ntawm cov ntawv luam tawm hauv Circuit Court boards yog tam sim no metallized. Cov txheej txheem ntawm welding coj mus rau ib lub vaj huam sib luag tsis tu ncua:
(1) Ncaj shear taub hau. Cov hlau lead ncaj qha hla dhau los ntawm lub qhov, thiab thaum lub sij hawm welding, ib qho tsim nyog tus nqi ntawm molten solder yog tusyees nyob ib puag ncig saum lub solder ncoo los ua ib tug conical zoo. Tom qab nws txias thiab solidifies, cov hlau lead ntau dhau raug txiav tawm. (Txoj kev tshwj xeeb tuaj yeem pom ntawm lub blackboard)
(2) Ncaj nraim faus koj lub taub hau. Cov hmoov txhuas dhau los ntawm lub qhov tsuas yog nthuav tawm qhov ntev uas tsim nyog, thiab cov khoom siv melted faus cov hlau lead hauv lub taub hau sib koom ua ke. Hom kev sib koom ua ke no zoo ib yam li cov duab hemispherical, thiab txawm hais tias nws zoo nkauj heev, yuav tsum tau them nyiaj tshwj xeeb rau kev tiv thaiv cov khoom cuav.
3. Kev tiv thaiv kev vuam tsis zoo
Vuam thev naus laus zis yog ib qho txuj ci tseem ceeb uas cov neeg nyiam xov tooj cua yuav tsum paub, thiab yuav tsum muaj kev xyaum ua kom txawj ntse.
1. Kev xaiv cov hlau uas tsim nyog yuav tsum siv cov khoom siv hluav taws xob tsawg tsawg rau cov khoom siv hluav taws xob welding.
2. Flux, yaj 25 feem pua rosin hauv 75 feem pua ntawm cawv los ntawm qhov hnyav li qhov flux.
3. Ua ntej siv hluav taws xob soldering hlau, tin yuav tsum tau siv. Txoj kev tshwj xeeb yog kom sov cov hlau soldering, thiab thaum nws tuaj yeem yaj cov tin soldering, siv cov flux, thiab tom qab ntawd sib npaug ntawm cov tin soldering rau lub taub hau hlau, kom lub taub hau hlau tuaj yeem noj cov tin sib npaug.
4. Vuam txoj kev: Polish lub ncoo thiab pins ntawm cov khoom uas zoo sandpaper thiab siv soldering flux. Npog tus nqi tsim nyog ntawm solder nrog lub taub hau hlau, kov lub vuam sib txuas, thiab tos kom tag nrho cov solder ntawm qhov sib koom ua ke kom yaj thiab muab tso rau hauv lub taub hau. Maj mam nqa lub taub hau ntawm lub taub hau mus rau ntawm tus pin tiv thaiv kom tawm ntawm qhov sib koom ua ke.
5. Lub sijhawm vuam yuav tsum tsis txhob ntev dhau, txwv tsis pub nws yog qhov yooj yim rau hlawv cov khoom. Yog tias tsim nyog, cov tweezers tuaj yeem siv los tuav cov pins los pab kom cov cua sov.
6. Lub solder sib koom yuav tsum muaj ib tug sinusoidal ncov puab, thiab saum npoo yuav tsum ci thiab du, nrog Wuxi burrs thiab nruab nrab tin ntsiab lus.
7. Tom qab welding, cov residual soldering flux ntawm lub rooj tsav xwm Circuit Court yuav tsum tau ntxuav nrog cawv kom tsis txhob muaj cov pa roj carbonized los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lub voj voog.
8. Cov kev sib xyaw ua ke yuav tsum tau soldered kawg, thiab cov hlau soldering yuav tsum muaj kev ntseeg siab hauv av los yog welded siv cov cua sov seem tom qab fais fab tuag. Xwb, siv lub qhov (socket) tshwj xeeb rau kev sib xyaw ua ke thiab muab lub qhov (socket) ua ntej ntsaws rau hauv qhov sib xyaw ua ke.
9. Cov hluav taws xob soldering hlau yuav tsum muab tso rau ntawm lub taub hau soldering.
