Cov kab ntawv luam tawm hauv Circuit Court tau siv hauv xov tooj cua tsim hluav taws xob tau ntev heev los txuas cov khoom siv hluav taws xob lossis cov khoom sib dhos. Tab sis ua ntej cov khoom siv lossis cov rooj sib txoos no txuas rau PCB los ntawm soldering lossis winding, nws yog qhov yuav tsum tau kos lub PCB nws tus kheej.
Nws yog qhov tsim nyog

Cov Lus Qhia
Kauj ruam 1
Npaj cov ntawv nyeem rau kev kos duab. Ua kom zoo li no, kho nws nrog nplua-txhuam ntoo txhuam thiab so nrog lub hnyav. Cov txheej txheem no yuav ua rau kom tus qauv sib txawv, nrog rau kev hnav zoo sib xws ntawm PCB.
Kauj ruam 2
Muab cov ntawv xa mus rau PCB nrog daim kab xev. Txhawm rau pauv qhov chaw ntawm lub qhov uas cov khoom sib txuas ntawm ib tus neeg yuav txuas, txuas nrog lub laum mus rau PCB (los ntawm ib sab ntawm daim ntawv txuas nrog Circuit Court) thiab khob nrog rab rauj. Sab nraum qab ntawm PCB, cov ntawv me me yuav tsum nyob hauv qhov.
Kauj ruam 3
Txuas cov ntawv uas tau txais ntawm PCB nrog kab. Hauv kev ua li ntawd, raug coj los ntawm cov muaj cov ntawv luam tawm hauv Circuit Court. Kos cov ciav hlau loj nrog cov kua roj vanish, thiab cov ntawv me uas muaj qhov ruaj khov.
Kauj ruam 4
Sab saum toj nrog cov kua roj vanish hla cov kab uas tau kos nrog lub cim cim tas mus.
Kauj ruam 5
Muab cov hmoov av sau ua chloride thiab muab cov kua dej nyeem rau nws.
