Tiv thaiv PCBA ncoo oxidation los txhawb kev ntseeg tau
Nyob rau hauv teb ntawm electronics chaw tsim, PCBA (luam tawm Circuit Court sib dhos) ncoo "uas cuam tshuam rau cov khoom lag luam thiab ntev} lub sij hawm kev ntseeg tau. Oxidation ncaj qha ua rau ib qho kev txo qis hauv ncoo kev muaj peev xwm, ua rau pom qhov tsis xws luag xws li cov pob txha txias thiab cov pob txha txias thiab tsis txaus. Yog li no, tiv thaiv kev tiv thaiv zoo ncoo Oxidation yog cov kauj ruam tseem ceeb hauv kev ua kom cov khoom lag luam zoo.
Hauv paus ua rau oxidation thiab cov tswv yim tiv thaiv me
Ncoo oxidation yog feem ntau tshwm sim los ntawm ib puag ncig cov khoom xws li cov av noo, sulfides, thiab halides. Cov tub ntxhais ntawm kev tiv thaiv cov lus dag hauv kev tsim kom muaj kev tiv thaiv huv thiab qhuav uas npog tag nrho cov txheej txheem los ntawm kev tsim khoom, cia khoom thauj khoom.
Cov ntsiab lus tseem ceeb rau tag nrho - txheej txheem tiv thaiv
Cov Kauj Ruam Ntau Lawm: Xaiv cov qauv tsim nyog ua tiav yog qhov tseem ceeb heev. Cov txheej txheem zoo li wm (oxidation tiv taus kev kho mob), Enricoless Nickel hloov kub los ua ib qho txheej txheem tiv thaiv kom cais cov ntaub thaiv cua. Cov chaw tsim khoom ntau lawm yuav tsum muaj cov kev tswj kom nruj thiab av noo.
Kev Cia Kawg: Qhov no yog theem tseem ceeb tshaj plaws rau kev tiv thaiv oxidation. Nws yog qhov tseem ceeb uas yuav tsum siv lub tshuab nqus tsev ntim nrog cov ntawv teev cia thiab cov av noo qhia cov npav. Lub chaw khaws cia zoo tshaj plaws yog ib puag ncig nitrogen lossis cov av noo tas nrho, uas txwv cov laug cam los ntawm noo noo thiab oxygen.
Tsheb thauj mus los thiab siv: PCBA cov laug cam yuav tsum tau soldered kom sai li sai tau tom qab qhib lub ntim (nyob rau hauv lub ntim (}}. Yog tias tsis tau siv tam sim ntawd, lawv yuav tsum rov muab dua nyob rau hauv lub tshuab nqus tsev.
Hauv cov ntsiab lus, los ntawm tsim kom muaj tag nrho- kev tiv thaiv "kev siv cov tuam txhab ua tau zoo ua rau cov khoom lag luam ua tiav, yog li tau txais kev ntseeg siab.
