Vim li cas rosin siv hluav taws xob soldering hlau?
Rosin yog siv los ua flux nyob rau hauv vuam thiab ua raws li ib tug flux. Kev hais lus theoretical, lub melting point ntawm flux yog qis dua li ntawm solder, thiab nws qhov tshwj xeeb lub ntiajteb txawj nqus, viscosity, thiab nto nro yog me dua li ntawm solder. Yog li ntawd, thaum soldering, cov flux melts ua ntej, thiab sai sai ntws thiab npog cov saum npoo ntawm solder kom cais cov huab cua thiab tiv thaiv cov hlau nto. Oxidation, thiab tuaj yeem hnov mob nrog oxide zaj duab xis rau ntawm qhov chaw ntawm lub solder thiab cov hlau yuav tsum tau welded ntawm qhov kub thiab txias kom yaj nws thiab rov qab cov hlau ntshiab. Tsim nyog soldering tin pab kom solder tawm ib tug txaus siab solder sib koom ua ke zoo thiab tuav lub nto gloss ntawm cov pob qij txha.
Rosin yog cov feem ntau siv flux, nws yog nruab nrab thiab yuav tsis corrode Circuit Court Cheebtsam thiab soldering hlau tswv yim. Yog tias nws yog lub rooj tsav xwm luam tawm tshiab, thov ib txheej ntawm rosin naj hoom rau saum npoo ntawm daim ntawv hlau ua ntej soldering. Yog hais tias nws yog ib lub rooj tsav xwm Circuit Court uas twb tau ua lawm, nws tuaj yeem ncaj qha soldered. Qhov tseeb, kev siv rosin nyob ntawm tus kheej tus cwj pwm. Qee tus neeg yuav poob qhov taub ntawm cov hlau nplaum hauv rosin txhua zaus lawv muab cov khoom siv; Dip ib co rosin rau saum. Kev siv cov rosin kuj yog ib qho yooj yim heev, tsuas yog qhib lub thawv rosin thiab dip lub taub hau ntawm lub zog hluav taws xob rau ntawm nws. Yog tias cov tub ntxhais siv tau siv rau vuam, nws yog ib qho tsim nyog yuav tau ntxiv qee cov rosin; Yog tias rosin tin soldering hlau yog siv (flux yog qhwv hauv cov tub ntxhais hlau), rosin yuav tsis siv.
Txij li cov hlau nto yuav tsim ib txheej ntawm oxide zaj duab xis tom qab kev sib cuag nrog huab cua, qhov kub thiab txias, qhov hnyav dua qhov oxidation. Cov txheej txheem ntawm oxide zaj duab xis tiv thaiv cov kua nplaum los ntawm ntub cov hlau, ib yam li cov roj ntawm lub khob yuav tiv thaiv dej los ntawm ntub dej. Flux yog ib yam khoom tshwj xeeb uas siv los tshem tawm oxide zaj duab xis, tseem hu ua flux.
Flux muaj peb txoj haujlwm:
1. Tshem tawm cov oxide zaj duab xis. Lub essence yog tias cov tshuaj nyob rau hauv lub flux undergo ib tug txo cov tshuaj tiv thaiv, yog li tshem tawm cov oxide zaj duab xis, thiab cov tshuaj tiv thaiv cov khoom yuav raug tshem tawm slag, ntab rau saum npoo ntawm solder.
2. Txo qhov nro ntawm qhov chaw, ua kom cov kua dej ntawm cov solder, thiab pab lub vuam kom ntub cov vuam.
3. Tiv thaiv oxidation. Tom qab nws melts, nws ntab rau saum npoo ntawm lub solder, tsim ib txheej cais, yog li tiv thaiv oxidation ntawm soldering nto.
