Hauv PCBA kev ua thiab kev tsim khoom, muaj ntau yam cuam tshuam rau qhov zoo ntawm SMT vuam, xws li PCB, cov khoom siv hluav taws xob, lossis cov khoom siv tshuaj txhuam, cov khoom siv thiab lwm yam teeb meem ntawm txhua qhov chaw yuav cuam tshuam qhov zoo ntawm SMT vuam, tom qab ntawd PCB txheej txheem kev kho mob yuav Dab tsi cuam tshuam rau qhov zoo ntawm SMT vuam?
Cov txheej txheem kev kho mob ntawm PCB feem ntau suav nrog OSP, hluav taws xob kub plating, tshuaj tsuag tin / dip tin, kub / nyiaj, thiab lwm yam, kev xaiv tshwj xeeb ntawm cov txheej txheem yuav tsum tau txiav txim siab raws li cov khoom xav tau tiag tiag, PCB nto kho yog cov txheej txheem tseem ceeb. Nyob rau hauv cov txheej txheem tsim PCB, feem ntau yog txhawm rau txhim kho vuam kev ntseeg tau thiab tiv thaiv corrosion thiab tiv thaiv oxidation lub luag haujlwm, yog li, PCB txheej txheem kev kho deg kuj yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm vuam!
Yog hais tias muaj teeb meem nrog PCB txheej txheem kev kho deg, ces nws yuav xub ua rau oxidation los yog kis kab mob ntawm lub solder sib koom, uas ncaj qha cuam tshuam rau kev ntseeg siab ntawm vuam, ua rau cov vuam tsis zoo, ua raws li cov txheej txheem ntawm PCB deg kho yuav cuam tshuam. Cov khoom siv ntawm cov khoom sib koom ua ke, xws li qhov nyuaj ntawm qhov chaw siab dhau lawm, nws yuav yooj yim ua rau cov pob qij txha poob los yog cov pob qij txha tawg.
