Yog vim li cas vim li cas PCB sib dhos tu ua ntau dua thiab tseem ceeb yog qhov ntawdPCB sib dhosKev ua cov pa phem ua rau muaj kev puas tsuaj loj rau cov kab hluav taws xob.Peb txhua tus paub tias qee qhov ionic lossis non-ionic pollution yuav raug tsim nyob rau hauv cov txheej txheem ua, uas feem ntau hu ua qee qhov pom lossis pom tsis pom.Thaum raug ib puag ncig los yog hluav taws xob, nws yuav ua rau cov tshuaj tiv thaiv corrosion los yog electrochemical corrosion, ua kom cov xau tam sim no lossis ion tsiv teb tsaws, thiab cuam tshuam rau kev ua haujlwm thiab kev pabcuam lub neej ntawm cov khoom.Niaj hnub no, cia peb tsom mus rau nthuav dav cov pa phem ntawm PCB kev ua haujlwm.
Cov pa phem txhais tau tias yog ib qho chaw tso nyiaj, impurities, slag inclusions thiab adsorbates uas txo cov tshuaj lom neeg, lub cev lossis hluav taws xob ntawm PCB los ua ke rau qib tsis tsim nyog.Nws feem ntau suav nrog cov hauv qab no:
1. PCB los ua ke deg pollution yuav tshwm sim los ntawm cov pa phem los yog oxidation ntawm cov khoom thiab cov khoom uas muaj PCB los ua ke thiab PCB nws tus kheej;
2. Thaum lub sij hawm tsim PCB los ua ke, solder paste, solder hlau, thiab lwm yam yuav tsum tau siv rau welding, thiab cov flux nyob rau hauv lub vuam txheej txheem yuav tsim residues nyob rau saum npoo ntawm PCB los ua ke kom muaj kuab paug, uas yog lub ntsiab pa phem;
3. Kev tuav tes soldering yuav raug tsim cov ntiv tes, thiab yoj soldering yuav raug tsim ib co Wave soldering kab thiab Vuam tais (fixture) kab.Tej zaum yuav muaj lwm yam kab mob ntawm PCB los ua ke saum npoo ntawm qhov sib txawv, xws li ntsaws cov kua nplaum, kub kub daim kab xev nplaum nplaum, ntiv tes thiab plua plav;
4. Electrostatic kuab paug tshwm sim los ntawm plua plav, dej thiab cov pa taws hnyav, chav ua haujlwm, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob txuas nrog PCB sib dhos hauv chaw ua haujlwm.
Cov saum toj no qhia tau hais tias cov pa phem feem ntau yog los ntawm cov txheej txheem sib dhos, tshwj xeeb tshaj yog cov txheej txheem vuam.Yog li ntawd, cov neeg ua haujlwm yuav tsum muaj cov txheej txheem kev ua haujlwm tshaj lij thiab kev ua haujlwm zoo, txwv tsis pub cov khoom siv PCB los ua ke yuav nyuaj tshwj xeeb.
