Tsib txoj kev kho loj rau hluav taws xob soldering hlau
1. Tom qab kev yuav cov txheej txheem tshiab hluav taws xob soldering hlau, yuav tsum tau ua kom tiav kev soj ntsuam. Txheeb xyuas cov ntsia hlau kho ua ntej kom pom tias lawv xoob, tom qab ntawd tshuaj xyuas cov hlua hluav taws xob rau kev puas tsuaj, tawg, lossis raug tooj liab, thiab thaum kawg siv multimeter los ntsuas qhov kev ncua deb ntawm lub ntsaws ob kawg. Ib txhais ko taw yuav tsum kov lub ntsis ntawm cov hluav taws xob soldering hlau thiab lwm txhais ko taw yuav tsum kov lub plug ntawm lub tshuab hluav taws xob ib txhij kom lub multimeter lub pointer nyob ruaj ruaj, txawm tias muaj luv luv Circuit Court los yog qhib Circuit Court, lub xeem kauj ruam Multimeter yog X10K. Nws yog siv tau tom qab kev ua tau hais tseg.
2. Txhawm rau kom ua tau zoo thiab ua kom ntev lub neej muaj txiaj ntsig ntawm lub tshuab hluav taws xob tshiab, cov txheej txheem hauv qab no yuav tsum tau ua. Koj yuav tsum xub ntxig lub taub hau rau hauv lub qhov cub cua sov ntawm tus txheej txheem hluav taws xob soldering hlau thiab tom qab ntawd nruj nreem cov hlau taub hau. Kho cov ntsia hlau. Lub soldering hlau yog muab tso rau ntawm rosin, lub hwj huam mov yog ntsaws rau hauv, thiab thaum kub nce mus txog rau thaum lub rosin melts, rosin tov yog siv rau lub ntsis ntawm lub soldering hlau.Tom qab ntawd nias lub rosin solder hlau nyob rau hauv lub ntsis ntawm lub soldering. hlau kom txog thaum soldering Melting, 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, cov 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. Noj tin (oxidation) thiab puas. 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 cov hlau soldering yuav tsum tau muab tua thiab txias. Tom qab ua tiav, koj yuav tsum ua haujlwm raws li cov khoom 1.3.2. Rau lub taub hau hlau ua los ntawm cov hlau, yog tias nws yog oxidized, koj tuaj yeem rov txhuam nws ntawm daim txhuam cev ntub dej thaum lub hwj chim thiab ntxiv rosin solder hlau kom txog rau thaum cov oxide txheej yog wiped tawm, thiab qhov saum npoo ntawm cov hlau taub yog resurfaced. Enamel ib txheej ntawm solder. Rau lub taub hau tawg thiab puas alloy, tsuas yog hloov nws.
4. Cov khoom siv hluav taws xob yog cov hluav taws xob soldering hlau. Nws ntshai ntawm cov dej noo thiab dej, ib yam li lwm yam khoom siv hluav taws xob. Yog li ntawd, txawm tias nws siv los yog tsis siv, yuav tsum paub txog cov dej noo thiab tsis txhob cia nws nyob ze dej lossis lwm qhov chaw ntawm cov av noo. Ib qho kom zoo dua yog tias nws tuaj yeem ua kom lub roj teeb lub neej. Txawm li cas los xij, qhov kev pab cuam lub neej ntawm cov hlau soldering yuav tsum tau ntev txaus los tiv thaiv cov xwm txheej cuam tshuam nrog hluav taws xob poob vim tias cov dej los yog cov av noo yuav txo tau cov hlau soldering cov rwb thaiv tsev.
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. Txoj kev tshwj xeeb yog raws li hauv qab no: Yog hais tias lub soldering tin hloov xim liab doog (oxidation) tam sim ntawd, lub soldering hlau taub yuav raug tshem tawm ntawm lub cua sov core. Yog tias qhov kub thiab txias qis dhau, cov rosin vaporizes maj mam thiab cov xaim hlau tsis tuaj yeem yaj tam sim ntawd, tom qab ntawd cov hlau nplaum tuaj yeem raug tshem tawm ntawm cov tub ntxhais cua sov. Tsiv me ntsis rau hauv. 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 ntawm cov hlau soldering 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.
