Hauv cov khoom siv hluav taws xob, post - shoding tu ntawm multi} {} Tus tseem ceeb ntawm cov khoom lag luam sib dhos) yog qhov tseem ceeb rau cov khoom muaj kev ntseeg tau thiab ntev. Residual Flux, soldder dross, thiab lwm cov dej paug tuaj yeem ua rau muaj kev sib tw luv luv, kev daws teeb meem, lossis kev cuam tshuam rau kev cuam tshuam nrog kev txhawb nqa kom huv.
- Qhov yuav tsum tau ntxuav
Tom qab soldering, cov seem xws li flux, oxides, thiab cov parspececececulations yuav ua raws li cov PCB. Siab - ceev} Cov qauv siv ntau ntau- Cov qauv sib dhos thiab dig muag / faus / faus / faus / faus / faus / faus rau cov khoom tsis huv. Kev tu tsis tiav tuaj yeem ua rau cov tshuab hluav taws xob hauv tshuab hluav taws xob lossis kev ua haujlwm tsis zoo.
- Txheej txheem Kev Xaiv Tsev
Kev tu tus neeg sawv cev Hom: Xaiv nruab ntawm dej - raws lossis cov kuab tshuaj ntxuav tawm nyob ntawm cov khoom paug. Water-based solutions are eco-friendly and suitable for most fluxes, while solvent-based cleaners are more effective against stubborn grease.
Cov khoom siv tu: Cov kev xaiv muaj xws li tshuaj tsuag, ultrasonic, lossis vapor theem tu. For multilayer double-sided PCBA, high-pressure spray combined with ultrasonic cleaning is recommended to ensure thorough cleaning of vias and underside components.
Txheej txheem tsis pom zoo: Txhim kho qhov kub thiab txias, ntev, thiab ntxuav tus neeg sawv cev. Piv txwv li, ultrasonic zaus ntau feem ntau los ntawm 40-80 kHz kom tsis txhob muaj kev puas tsuaj loj.
- Cov kev txiav txim siab tseem ceeb
Kev Kuaj Xyuas Kev Ncaj Ncees: Xyuas kom cov neeg sawv cev tu tau sib xws nrog PCB cov ntaub ntawv thiab cov khoom sib xyaw kom tiv thaiv kom tsis txhob muaj qhov o lossis daim ntawv lo.
Kev tswj kom qhuav: Cov khaubncaws sab nraud povtseg ntawm cov txheej txheem ntawm cov multilayer multiSe, xav tau kom muaj zog ziab khaub ncaws (piv txwv li cov huab cua kub lossis tshuab ziab qhuav) kom tiv thaiv oxidation.
Ib puag ncig thiab kev nyab xeeb ua raws li: ua ntej haloogen {}}} Pub dawb, tsawg} Tus qauv sib ntsib ROHS cov qauv.
Tshaj tawm - soldering tu yog qhov tseem ceeb ntawm kev ntseeg tau ntawm multilayer ob {} {1} {} {sided pcba. Cov qauv kev ua kom huv yuav tsum xaiv cov txheej txheem tu kom zoo raws li cov cim tswj hwm thiab cov txheej txheem tswj nruj me ntsis kom ua tiav cov txiaj ntsig thiab ib puag ncig zoo.
