Kev tu thiab kho ntawm hluav taws xob soldering hlau
1.1. Tom qab cov khoom siv hluav taws xob tshiab zoo tib yam tau coj los, nws yuav tsum tau kuaj xyuas. 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 siv multimeter los ntsuas ob qhov kawg ntawm lub ntsaws. Txawm hais tias muaj luv luv Circuit Court los yog qhib Circuit Court, lub xeem 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 hluav taws xob hlau nyob rau tib lub sij hawm, lub pointer ntawm lub multimeter tsis pub txav mus los. Tom qab cov kauj ruam saum toj no, nws tuaj yeem siv tau.
1.2 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 taub hau ntawm lub taub hau rau hauv lub qhov cub cua sov, thiab nruj nreem ntsia hlau ntsia hlau los kho nws Screw. Plug rau hauv lub hwj chim, muab cov hlau soldering rau ntawm rosin, thiab thaum kub nce mus txog rau thaum lub rosin melts, lub ntsis ntawm cov hlau soldering yog them nrog ib txheej ntawm rosin tov. Tom qab ntawd muab cov rosin solder hlau rau ntawm qhov kawg ntawm cov hlau soldering kom txog thaum lub solder melts, thiab thaum kawg tom qab lub solder yog tusyees coated nrog ib 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.
1.3 Thaum lub sij hawm siv, qhov chaw ua hauj lwm ntawm cov hlau taub hau 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.
1.4 Cov khoom siv hluav taws xob hluav taws xob yog cov khoom siv hluav taws xob, thiab zoo li lwm yam khoom siv hluav taws xob, nws ntshai dej thiab noo noo, yog li thaum siv cov ntaub ntawv PDF lossis khaws cia thaum tsis siv, ceev faj kom tsis txhob ntub rau hauv ib qho chaw. nrog dej los yog av noo. Ntawm qhov tod tes, 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.
1.5 Thaum lub sij hawm siv hluav taws xob soldering hlau, peb tuaj yeem ua lub neej ntev kev pab cuam 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 nplaum tsis tuaj yeem yaj tam sim ntawd, koj tuaj yeem muab lub hau ntawm cov hlau nplaum rau hauv cov 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.
