Txoj kev xaiv raug ntawm hluav taws xob soldering hlau taub
Nws yog ib qho tseem ceeb heev uas yuav tau xaiv qhov loj me thiab cov duab ntawm cov hlau taub hau. Xaiv txoj cai soldering hlau taub yuav ua rau kev ua hauj lwm zoo dua thiab ua rau kom cov kav ntev ntawm cov hlau taub hau. Qhov loj ntawm lub taub hau ntawm lub taub hau yog ncaj qha ntsig txog lub peev xwm kub. Qhov loj dua qhov loj ntawm lub taub hau, qhov loj dua lub peev xwm kub, thiab qhov me me ntawm cov hlau taub hau, qhov me me lub peev xwm kub. Thaum ua haujlwm txuas ntxiv, siv lub taub loj dua kom txo qhov kub thiab txias. Tsis tas li ntawd, vim hais tias lub peev xwm ntawm lub taub hau loj loj yog qhov siab, qhov kub tsis tshua muaj peev xwm siv tau thaum lub sij hawm soldering, thiab lub taub hau hlau tsis yooj yim rau oxidize, uas ua rau nws lub neej nce. Feem ntau hais lus, qhov luaj li cas ntawm lub taub hau hlau yog raws li tsis cuam tshuam rau cov khoom nyob ib sab. Xaiv cov geometry uas tso cai rau kev sib cuag nrog cov sib koom ua ke tuaj yeem txhim kho kev ua haujlwm zoo.
Rau lub ntsiab ntsuas uas tsis muaj hlau lead tshwj xeeb hluav taws xob soldering hlau yuav tsum muaj
1. Qhov tshwj xeeb ruaj khov vuam kub, ruaj khov tsawg dua lossis sib npaug ± 2 degree (tsis muaj lub xeev load);
2. Cov khoom siv hluav taws xob muaj zog, hluav taws xob cua sov yuav tsum siab dua lossis sib npaug li 70W;
3. Qhov kub thiab txias muaj nuj nqi ntawm cov cua kub ceev heev, ib txwm vuam tsis pub dhau 10S tom qab fais fab tuag;
4. Kub them rau cov cua sov tam sim ntawd, nrog rau cov cua kub ceev ceev hauv vib nas this;
5. Txhua yam khoom siv tau dhau daim ntawv pov thawj tiv thaiv ib puag ncig, thiab tau nruab nrog cov lus qhia tsis pub siv lead ua lub neej ntev;
6. Kev nyab xeeb thiab txhim khu kev qha grounding hlau ntaus ntawv, grounding kuj tsawg dua los yog sib npaug rau 2Ω.
Kev ceev faj rau kev siv cov hlau soldering (soldering hlau soldering technology ceev faj)
(1) Cov hlau uas tau muag tshiab yuav tsum tau dipped rau hauv ib txheej ntawm cov tin ua ntej siv (lub zog ntawm cov hlau, thiab tom qab ntawd siv lub tin bar kom ze rau qhov kawg ntawm cov hlau soldering thaum cov hlau soldering yog rhuab mus rau ib qho chaw), thiab lub taub hau hlau uas tau siv ntev ntev Cov ntaub ntawv ci, tom qab ntawd tig rau hluav taws xob cua sov kom sov, dipped lub taub hau ntawm cov hlau soldering nrog me ntsis rosin, thiab tin nws thaum lub rosin haus luam yeeb, kom cov nplaim. ntawm qhov kawg ntawm cov hlau soldering yog thawj coated nrog ib txheej ntawm tin.
(2) Tom qab siv cov hlau soldering rau ib lub sij hawm, tej zaum yuav muaj tin nplai ntawm qhov kawg ntawm cov hlau soldering. Peb tuaj yeem maj mam so nws nrog ib daim ntaub ntub dej thaum cov hlau rhuab. Yog tias muaj cov pits lossis oxidized blocks, siv cov ntaub ntawv zoo los kho lossis hloov ncaj qha rau cov hlau taub hau.
(3) Tom qab hluav taws xob soldering hlau yog energized, qhov kub yog siab li 250 degrees Celsius. Thaum tsis siv, nws yuav tsum tau muab tso rau ntawm qhov muag muag, tab sis thaum nws tsis siv rau lub sijhawm ntev, lub zog yuav tsum raug txiav tawm kom tsis txhob muaj qhov kub ntawm qhov "hlawv" ntawm cov hlau taub hau (oxidized). Nws yog ib qho tsim nyog los tiv thaiv cov hluav taws xob soldering hlau los ntawm scalding lwm yam khoom, tshwj xeeb tshaj yog cov hlua fais fab. Yog tias cov txheej txheej rwb thaiv tsev raug kub hnyiab los ntawm cov hlau soldering yam tsis tau saib xyuas, nws yuav yooj yim ua rau muaj kev nyab xeeb.
(4) Tsis txhob ntaus cov hlau nplaum hnyav, kom tsis txhob poob siab thiab tawg cov cua sov xaim lossis cov hlau lead hauv cov hlau soldering thiab ua rau lub cev tsis zoo.
