PCBA ua nyob rau hauv cov txheej txheem vuam, yog qhov yuav tsum tau siv qee cov ntaub ntawv vuam yog qhov ua tau zoo los yog ua kom zoo nkauj tiv thaiv, thiab cov kev sib tw ua kom zoo lossis tsis zoo ntawm cov vuam sib txuas.
Flux, raws li lub npe cuam tshuam yog siv los pab vuam, yog kom muaj kev cuam tshuam zoo rau cov khoom siv vuam, yog li peb yuav tsum tau them sai sai ntawm cov khoom zoo rau cov lus sib xyaw ua ke; Solder, vim hais tias cov hlau raw cov ntaub ntawv yog feem ntau tin, solder ua ib qho tseem ceeb ntawm cov khoom siv vuam, txawm tias nyob rau hauv cov reawer lossis yoj soldering lossis tso zis. Yoj schdering lossis tom qab vuam ua yog qhov tseem ceeb, nws yuav tsum tau muab faib ua ob hom sib luag, vim yog cov nyom uas muaj vuam ua ke xws li kev siv vuam yog cov solder-raws li cov solder; solder resist, as the name implies, is to prevent the welding of the welding process in the welding of the need to weld only a small part of it, the rest of the board is not to be welded, then you need to use solder resist, the main role is to prevent the rest of the welding process in the welding process, the main role is to prevent the welding process, the rest of the board is not to be welded. Lub luag haujlwm yog txhawm rau tiv thaiv kom tsis txhob muaj kev sib tw ntawm cov kab hlau tsis tas yuav tsum tau weld ib feem ntawm cov khoom siv yog puas; Tu tus neeg saib xyuas, hauv kev siv cov tshuaj tua flux yuav tawm ntawm cov thawj coj ntawm lub rooj tsavxwm, thiab lub luag haujlwm ntawm kev ntxuav tu yog kom tshem tawm cov vuam cov vuam.
