Hauv cov txheej txheem tsim khoom, tom qab PCB raug tsim thiab muab tso rau lub sijhawm, nws kuj muaj lub sijhawm los nqus dej noo rau hauv ib puag ncig, uas yooj yim ua rau paj kws lossis delamination ntawm PCB. Vim hais tias thaum lub PCB muab tso rau hauv qhov kub ntawm ntau tshaj 100 degree ib puag ncig, xws li rov qab vuam rauv, yoj vuam rauv, cua kub leveling los yog tes vuam txheej txheem, dej yuav tig mus rau hauv dej vapor, thiab ces nthuav nws cov ntim kom tawg sai sai. PCB pawg thawj coj saib.
Yog li ntawd, peb tau qhia tshwj xeeb uas qhia txog PCB ci lub thawv kom paub meej qhov zoo ntawm PCB, thiaj li ua kom peb cov khoom zoo.
