Pretreatment ntawm ib qho tshiab-kub hluav taws xob soldering hlau ua ntej siv
Ua ntej siv qhov kub thiab txias tas li, ib txheej ntawm cov hlau yuav tsum tau coated rau ntawm qhov kawg ntawm cov hlau ua ntej nws tuaj yeem siv tau ib txwm. Tom qab siv qhov ntsuas kub tsis tu ncua rau lub sijhawm, ib txheej ntawm oxide yuav tsim rau ntawm cov hniav thiab ib puag ncig ntawm cov hlau soldering, uas ua rau nws nyuaj rau "noj solder". Lub sijhawm no, cov txheej txheem oxide tuaj yeem raug xa tawm thiab tuaj yeem rov coated.
2, tuav txoj kev ntawm qhov kub thiab txias soldering hlau:
a. Txoj kev tuav rov qab: Nws yog tuav tus kov ntawm qhov kub thiab txias hluav taws xob soldering hlau hauv xib teg nrog tsib ntiv tes. Txoj kev no yog tsim rau high-power tas li kub soldering hlau, uas yuav siv tau rau weld workpieces nrog loj tshav kub dissipation.
b. Txoj kev tuav zoo: Nws yog tuav tus tuav ntawm qhov kub thiab txias ntawm hluav taws xob soldering hlau nrog plaub ntiv tes tshwj tsis yog tus ntiv tes xoo, thiab nias tus ntiv tes xoo rau ntawm cov hlau soldering. Txoj kev no kuj siv ib tug kuj loj thiab nkhaus soldering hlau taub.
c. Cwj mem tuav txheej txheem: Tuav lub ntsuas kub tsis tu ncua xws li tuav tus cwj mem, tsim nyog rau lub zog hluav taws xob tsawg, soldering me me workpieces
3, Vuam cov kauj ruam:
Thaum lub sij hawm vuam txheej txheem, cov cuab yeej yuav tsum tau teem kom zoo zoo thiab qhov kub thiab txias soldering hlau yuav tsum tau tuav ruaj khov thiab ua raws. Nws yog qhov zoo tshaj plaws los siv tubular solder hlau nrog rosin rau kev sib koom tes dav dav. Koj yuav tsum tuav tus kov ntawm qhov kub thiab txias hluav taws xob soldering hlau nyob rau hauv ib txhais tes thiab cov hlau soldering nyob rau hauv lwm yam tes.
1. Ib txoj hauv kev yog kom ceev cov cua sov thiab cov hlau nplaum rau hauv kev sib cuag nrog cov hlau cored, tom qab ntawd kov thaj tsam ntawm qhov taw tes, siv cov hlau nplaum los pab rau qhov pib cua sov los ntawm cov hlau soldering mus rau qhov chaw ua haujlwm, thiab tom qab ntawd txav cov hlau tawm ntawm qhov chaw mus rau soldered.
2. Ib txoj hauv kev yog muab cov hlua hlau txuas rau hauv kev sib cuag nrog cov pins / pads, thiab muab cov hlua khi ntawm cov hlua hlau thiab cov pins los ua ib qho kev sib txuas; Tom qab ntawd ceev nrooj txav cov tin hlau mus rau sab nraud ntawm thaj chaw sib koom ua ke.
Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm kev tsim khoom, feem ntau muaj kev puas tsuaj rau PCB lossis cov khoom siv los ntawm kev siv qhov kub thiab txias, siab dhau, lub sijhawm khaws cia ntev, lossis kev sib xyaw ntawm peb.
