1. Kev cia zoo: qhov kub thiab txias yog tsawg dua 25 degrees, qhov txheeb ze av noo tsawg dua 65 feem pua, nrog rau kev tswj qhov kub thiab txias, thiab ib puag ncig sab hauv tsev tsis muaj corrosive gases.
2. Kev khaws cia dav dav: qhov kub tsis siab tshaj 35 degrees, qhov txheeb ze av noo tsawg dua 75 feem pua, thiab ib puag ncig sab hauv tsev tsis muaj corrosive gases.
Qhov kub ntawm lub tsev khaws khoom uas PCBA khaws cia yog qhov zoo tshaj plaws tswj ntawm 23 ± 3 degree thiab 55 ± 10 feem pua RH. Nyob rau hauv cov xwm txheej zoo li no, PCBA boards nrog cov kev kho mob saum npoo xws li immersion kub, electro-kub, tin spraying, thiab nyiaj plating feem ntau tuaj yeem khaws cia rau 6 lub hlis. Immersion silver, immersion tin, OSP thiab lwm qhov chaw kho PCBA boards feem ntau tuaj yeem khaws cia rau 3 lub hlis.
Rau PCBA boards uas tsis tau siv rau lub sijhawm ntev, nws yog qhov zoo tshaj plaws rau cov tuam txhab hluav taws xob hluav taws xob los pleev xim ib txheej ntawm peb-pov thawj xim rau lawv. Cov dej num ntawm cov xim peb-pov thawj tuaj yeem tiv thaiv ya raws, plua plav thiab oxidation. Ua li no, PCBA txee lub neej yuav nce mus rau 9 lub hlis.
