Tsib kauj ruam los tswj koj cov hlau soldering
1. Tom qab tau txais ib qho zoo tib yam tshiab soldering hlau, yuav tsum tau soj ntsuam tsim nyog. Ua ntej, xyuas seb qhov kho cov ntsia hlau puas xoob. Qhov thib ob, saib seb cov hlua hluav taws xob puas muaj qhov tawg, raug tooj liab, lossis puas. Tom qab ntawd siv lub multimeter los ntsuas ob qhov kawg ntawm lub ntsaws. Txawm hais tias muaj luv luv Circuit Court los yog qhib Circuit Court, thaum kawg teem lub multimeter rau X10K, kov lub soldering hlau taub nrog ib tug ko taw, thiab kov lub soldering hlau plug nrog ib tug ko taw tib lub sij hawm. Lub multimeter pointer tsis pub txav mus los. Nws tuaj yeem siv tau tom qab cov kauj ruam saum toj no.
2. Thaum siv lub taub hau hlau tshiab thawj zaug, koj yuav tsum siv cov txheej txheem hauv qab no los txhim kho nws txoj kev siv kom zoo thiab txuas ntxiv nws lub neej kev pab. 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 lub qhov thiab zawm lub soldering hlau taub kho nws. Ntsia hlau. Plug rau hauv lub hwj chim, nias lub soldering hlau ntawm lub rosin, thiab raws li qhov kub thiab txias nce mus txog rau thaum lub rosin melts, lub taub hau soldering hlau yog them nrog ib txheej ntawm rosin tov. Tom qab ntawd nias lub rosin solder hlau ntawm lub taub hau hlau kom txog thaum lub solder melts. , Thaum kawg, tom qab lub solder yog sib npaug nrog ib txheej ntawm tin rau ntawm lub taub hau ntawm chrome taub hau, cov hlau soldering tuaj yeem muab tso rau hauv ib txwm siv.
3. Thaum lub sij hawm siv, qhov chaw ua hauj lwm ntawm lub taub hau soldering hlau yog hnyav heev, qhov kub thiab txias yog heev, thiab nws yooj yim rau oxidize. Lub flux yog corrosive thiab yooj yim rau corrode. Cov khoom siv vuam muaj siab hardness thiab yooj yim rau hnav. Teeb meem ntawm lub taub hau hlau yog feem ntau tshwm sim los ntawm kev tsis noj mov. Tin (oxidation) thiab kev puas tsuaj. Rau cov lus qhia ntawm cov hlau uas 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 txias yam tsis tau txiav tawm lub hwj chim ua ntej ua haujlwm. Tom qab ntawd, koj yuav tsum ua raws li kev ua haujlwm ntawm 1.3.2. Rau lub taub hau hlau uas 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 tshem tawm, thiab qhov saum npoo ntawm lub taub hau hlau tuaj yeem rov ua dua. enameled. Thov ib txheej ntawm solder. Rau tawg thiab puas alloy taub hau, tib txoj kev xaiv yog los hloov lawv.
4 Cov hlau nplaum yog cov khoom siv hluav taws xob, thiab zoo li lwm yam khoom siv hluav taws xob, nws ntshai dej thiab ya raws. Yog li ntawd, thaum siv los yog tawm hauv cov ntaub ntawv PDF yam tsis tau siv "pdfFactory Pro" sim version creation www.fineprint.cn, ceev faj kom tsis txhob ntub dej. Khaws nyob rau hauv ib qho chaw uas muaj dej los yog noo noo yuav tsis tsuas yog ncua lub neej kev pab cuam ntawm lub soldering hlau, tab sis kuj ua kom muaj kev ruaj ntseg, vim hais tias dej los yog noo noo yuav ua rau lub rwb thaiv tsev kev ua tau zoo ntawm cov hlau soldering yuav txo, ua rau hluav taws xob poob siab.
5. Thaum lub sij hawm siv cov hlau soldering, peb tuaj yeem txuas lub neej kev pab cuam ntawm lub taub hau thiab txhim kho cov vuam zoo ntawm cov hlau los ntawm kev kho cov hlau soldering. Cov txheej txheem tshwj xeeb yog raws li hauv qab no: Yog tias qhov kub thiab txias dhau lawm, rosin yuav vaporize sai li sai tau thaum nws kov nws. Yog hais tias lub solder hloov golden xim (oxidized) tam sim ntawd, koj tuaj yeem txav cov hlau taub hau tawm ntawm cov tub ntxhais cua sov. Yog tias qhov kub thiab txias qis dhau lawm thiab cov rosin vaporizes maj mam thaum ntsib nws, thiab cov hlau nplaum tsis tuaj yeem yaj tam sim ntawd, koj tuaj yeem txav cov hlau taub hau mus rau hauv cov tub ntxhais cua sov. Txav mus me ntsis kom txog thaum lub solder ntxiv thiab nws melts tam sim ntawd. Nws yuav tsis oxidize 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 yuav tsum tsis txhob tsawg dua 1.5CM hauv cov tub ntxhais cua sov. Qhov ntev ntawm 50W hluav taws xob soldering hlau yuav tsum tsis pub tsawg tshaj 1.5CM. Qhov ntev ntawm cov hlau nplaum sab laug hauv cov tub ntxhais cua sov tsis tuaj yeem tsawg dua 2.0CM, txwv tsis pub lub neej kev pab cuam ntawm cov tub ntxhais cua sov yuav luv.
