Tsib kauj ruam rau kev saib xyuas thiab kho cov hluav taws xob soldering hlau
1. Tom qab cov khoom siv hluav taws xob tshiab zoo tib yam tau coj los, yuav tsum tau ua qhov kev tshuaj xyuas tsim nyog. Ua ntej, xyuas seb qhov kho cov ntsia hlau puas xoob, thiab tom qab ntawd saib seb lub hwj chim qaum puas muaj cov kab nrib pleb, raug tooj liab, kev puas tsuaj, thiab tom qab ntawd ntsuas ob qhov kawg ntawm lub ntsaws nrog lub multimeter Txawm tias muaj luv luv lossis qhib Circuit Court, qhov kawg. kauj ruam ntawm lub multimeter yog X10K, ib tug ko taw kov lub ntsis ntawm cov hluav taws xob soldering hlau, thiab lwm yam ko taw kov lub plug ntawm lub hluav taws xob hlau nyob rau tib lub sij hawm, lub pointer ntawm lub multimeter tsis pub txav mus. Tom qab cov kauj ruam saum toj no, nws tuaj yeem siv tau.
.2 Thaum siv lub tshuab hluav taws xob tshiab tshiab thawj zaug, cov txheej txheem hauv qab no yuav tsum tau siv los txhim kho nws qhov zoo thiab ua kom nws lub neej ua haujlwm ntev. Yog hais tias nws yog ib qho yooj yim hluav taws xob soldering hlau, koj yuav tsum xub nruab lub soldering hlau taub rau hauv lub qhov cub cua sov qhov thiab zawm lub soldering hlau taub kho lub hau. Txuas lub hwj chim, muab cov hlau soldering rau ntawm rosin, thiab thaum kub nce mus txog thaum lub rosin melts, lub hau ntawm cov hlau soldering yog them nrog ib txheej ntawm rosin tov. Tom qab ntawd nias lub rosin solder hlau ntawm lub ntsis ntawm cov hlau soldering kom txog rau thaum lub soldering melting, thiab thaum kawg tom qab lub solder yog tusyees coated nrog ib tug txheej ntawm tin rau ntawm lub taub hau ntawm chromium lub taub hau, hluav taws xob soldering hlau yuav muab tso rau hauv ib txwm siv.
3 Thaum siv. Qhov chaw ua hauj lwm ntawm cov hluav taws xob soldering hlau taub yog hnyav heev, qhov kub thiab txias, thiab nws yooj yim rau oxidize. Lub flux yog corrosive thiab yooj yim rau corrode. Tin (oxidation) thiab kev puas tsuaj. Rau cov lus qhia hlau soldering ua los ntawm cov hlau tooj liab, koj tuaj yeem siv cov ntaub ntawv sib txawv kom tshem tawm cov oxide txheej los yog luas cov hlau taub hau rau qhov xav tau. Nco ntsoov tias nws yuav tsum tau ua nyob rau hauv cov xwm txheej uas cov hluav taws xob soldering hlau tsis raug kaw thiab txias. Tom qab ntawd, koj yuav tsum ua haujlwm raws li cov khoom 1.3.2. Rau cov lus qhia ntawm cov hlau nplaum ua los ntawm cov hlau, yog tias lawv tau oxidized, koj tuaj yeem rov txhuam lawv ntawm daim txhuam cev ntub dej thaum lub hwj chim thiab ntxiv rosin solder hlau kom txog thaum lub oxide txheej tau so. Txheej kawg ntawm solder. Rau lub taub hau alloy uas tau tawg thiab puas, tsuas yog hloov nws.
4. Cov hluav taws xob soldering hlau yog cov khoom siv hluav taws xob. Zoo li lwm yam khoom siv hluav taws xob, nws ntshai dej thiab av noo. Yog li ntawd, thaum siv los yog khaws cia thaum tsis siv, xyuam xim rau cov dej noo thiab tsis txhob muab cia rau hauv qhov chaw uas muaj dej los yog av noo. Ntawm ib sab, nws tuaj yeem ua rau lub neej ntev ntawm cov hluav taws xob soldering hlau. Ntawm qhov tod tes, nws tseem yuav ua kom muaj kev nyab xeeb, vim tias dej los yog av noo yuav ua rau lub rwb thaiv tsev kev ua tau zoo ntawm cov hluav taws xob soldering hlau txo qis, ua rau hluav taws xob poob siab.
5 Thaum lub sij hawm siv hluav taws xob soldering hlau, peb tuaj yeem ua kom lub neej ntev ntawm cov hlau soldering thiab txhim kho qhov zoo ntawm cov hluav taws xob soldering hlau los ntawm kev kho cov hluav taws xob soldering hlau. Yog hais tias lub soldering tin hloov xim liab doog (oxidized) tam sim ntawd, koj tuaj yeem txav lub hau ntawm cov hlau soldering tawm ntawm cov tub ntxhais cua sov. Yog tias qhov kub thiab txias qis dhau, qhov vaporization ntawm rosin qeeb, thiab cov hlau tsis tuaj yeem yaj tam sim ntawd, koj tuaj yeem muab lub hau ntawm cov hlau soldering rau hauv cov tub ntxhais cua sov. Txav mus rau hauv me ntsis. Nws yuav yaj tam sim tom qab ntxiv solder, thiab nws yuav tsis oxidized nyob rau hauv ib lub sij hawm luv luv (15 ~ 20 vib nas this). Nco ntsoov tias qhov ntev ntawm qhov kawg ntawm 30W hluav taws xob soldering hlau nyob rau hauv cov tub ntxhais cua sov yuav tsum tsis txhob tsawg tshaj li 1.5CM. 50W hluav taws xob soldering hlau Qhov ntev ntawm cov hlau soldering tshuav nyob rau hauv cov tub ntxhais cua sov yuav tsum tsis txhob tsawg tshaj li 2.0CM, txwv tsis pub lub neej kev pab cuam ntawm lub cua sov tub ntxhais yuav luv luv.
