Kev nkag siab zoo thiab cov qauv siv hluav taws xob soldering hlau
1: Nkag siab txog hluav taws xob soldering hlau, uas yog cov cuab yeej siv feem ntau hauv vuam.
1. Muaj nuj nqi: Nws hloov hluav taws xob hluav taws xob mus rau lub zog thermal kom sov thiab vuam cov ntsiab lus vuam. Qhov kev vam meej ntawm vuam feem ntau yog nyob ntawm seb nws zoo npaum li cas. Feem ntau hais lus, qhov siab dua lub zog thiab cua sov ntawm lub tshuab hluav taws xob hluav taws xob, qhov kub ntawm lub taub hau hlau soldering ntau dua.
2. Lub zog siv hluav taws xob feem ntau yog 20W; 25 W; 30W; 40W; 60 W; 100 W
3. Cua sov daim ntawv ntawm hluav taws xob soldering hlau: sab hauv cua sov; Sab nraud cua sov.
4. Cov khoom siv feem ntau ntawm cov hlau nplaum: cov hlau nplaum, cov khoom siv tin suction, tweezers, electrostatic bracelet, Diagonal pliers, absorbent sponge.
2: Kev ceev faj rau kev siv hluav taws xob soldering hlau
1. Kev npaj ua ntej siv cov hlau soldering.
Cov hluav taws xob soldering hlau yuav tsum tau coated nrog tin ua ntej siv. Txoj kev tshwj xeeb yog kom sov cov hluav taws xob soldering hlau. Thaum lub soldering tin tuaj yeem yaj tam sim no, cov tin hlau yuav tsum sib npaug ntawm lub taub hau hlau kom lub taub hau hlau tuaj yeem noj ib txheej ntawm cov tin sib npaug. (Faj seeb: Nws yog ib qho tshuaj tiv thaiv rau cov khoom siv tshiab uas tau yuav cov hlau nplaum kom haus luam yeeb thaum lub sij hawm cua sov)
2. Ua haujlwm kom raug.
Nws tuaj yeem ua kom lub cev thiab lub hlwb noj qab haus huv ntawm tus neeg teb xov tooj thiab txo qis kev raug mob ntawm kev ua haujlwm. Txhawm rau txo qhov kev puas tsuaj ntawm cov tshuaj emissions los ntawm vuam flux thaum cua sov thiab txo qhov nqus ntawm cov pa phem, qhov kev ncua deb ntawm cov hlau mus rau lub qhov ntswg yuav tsum tsis pub tsawg tshaj 20cm, thiab 30cm feem ntau pom zoo.
3. Ua ntej siv lub tshuab hluav taws xob, xyuas seb qhov hluav taws xob siv tau zoo li cas rau qhov nominal voltage ntawm cov hlau soldering.
4. Lub tshuab hluav taws xob soldering hlau yuav tsum tau muab tso rau hauv av thiab zoo hauv av.
5. Thaum siv cov hlau nplaum, nws yog ib qho tsim nyog yuav tsum tau hnav ib txoj hlua hluav taws xob electrostatic, thiab cov hlua hluav taws xob electrostatic yuav tsum tau zoo hauv av. (Ceeb Toom: Cov xaim hauv av zoo li qub thiab cov hlau nplaum hlau yuav tsum tau sib cais)
6. Tom qab lub tshuab hluav taws xob hluav taws xob tau siv rau, nws tsis tuaj yeem raug khob, disassembled, lossis ntsia nrog cov khoom siv hluav taws xob.
7. Cov hlau nplaum hluav taws xob yuav tsum tau ua kom qhuav thiab tsis txhob siv nyob rau hauv qhov chaw ntub dej ntau dhau los yog los nag.
Thaum disassembling lub taub hau hlau soldering, tua lub hwj chim mov.
Tom qab tua hluav taws, siv cov cua sov uas tseem tshuav los siv ib txheej ntawm cov tin ntawm lub taub hau hlau los tiv thaiv nws.
Thaum muaj txheej txheej dub oxide ntawm lub taub hau hlau, cov oxide tuaj yeem raug so tawm ntawm cov dej nqus dej thiab tinned tam sim ntawd. (tsis tuaj yeem txhuam nrog rab riam)
11. Sponges yog siv los sau cov tin slag, tin hlaws, thiab oxides. Nws raug nquahu kom pinch lawv nrog koj txhais tes kom txaus kom tsis txhob muaj dej ntws tawm.
12. Lub tshuab hluav taws xob hluav taws xob yuav tsum tsis txhob siv lub sijhawm ntev yam tsis siv, vim qhov no tuaj yeem yooj yim ua rau cov tub ntxhais hlau soldering kom nrawm oxidation thiab kub hnyiab, ua rau nws lub neej luv, thiab tseem ua rau lub taub hau hlau taub hau oxidize vim cua sov ntev. , txawm raug "hlawv" thiab tsis "noj mov"
3: Solder
Solder yog ib hom fusible hlau uas tuaj yeem txuas cov khoom sib txuas ua rau cov ntsiab lus sib txuas ntawm cov ntawv luam tawm. Tin (Sn) yog ib tug mos mos thiab ductile silver dawb hlau nrog ib tug melting point ntawm 232 degree. Nws muaj cov tshuaj lom neeg ruaj khov ntawm chav sov, tsis yooj yim oxidized, tsis plam nws cov xim hlau, thiab muaj zog tiv thaiv atmospheric corrosion. Lead (Pb) yog ib lub teeb ci xiav dawb hlau uas muaj qhov melting point ntawm 327 degree. High purity lead muaj zog atmospheric corrosion kuj thiab zoo tshuaj stability, tab sis nws yog teeb meem rau tib neeg noj qab haus huv. Ntxiv ib qho kev faib ua feem ntawm cov hlau lead thiab ib qho me me ntawm lwm cov hlau rau tin tuaj yeem ua rau nws tsis tshua muaj melting point, zoo fluidity, muaj zog adhesion rau cov khoom thiab cov xov hlau, siab mechanical zog, thiab zoo conductivity.
