Kev ua haujlwm kub ntawm PCB nrog cov khoom sib txawv yog txawv. Tsis tas li ntawd, qhov luaj li cas ntawm PCB tooj liab clad cheeb tsam thiab board thickness yog ze ze rau qhov kub thiab txias, yog li qhov ntsuas kub ntawm lub cub tawg yuav ua rau cov khoom sib thooj thaum lub sij hawm tsim khoom loj.
Kuj tseem muaj cov kev cai tshwj xeeb rau PCB cia. Lub ntim khoom tuaj yuav tsum yog lub tshuab nqus tsev ntim, thiab lub rooj tsavxwm tseem yuav tsum tau qhuav tsis muaj dej, txwv tsis pub lub ncoo ntawm lub rooj tsavxwm yooj yim rau oxidize. Tsis tas li ntawd, daim hlau nrog BGA thiab tuab tuab yuav tsum tau ci ua ntej thaj chaw tsim khoom. Lub sij hawm ci nyob ntawm lub phaj specification, feem ntau yog 4 teev lossis 8 teev.
Kev kuaj PCB: PCB cov chaw tsim khoom muaj ob txoj hauv kev rau kev tsim cov PCBs. Flying Probe feem ntau yog siv rau kev tsim khoom me me, thiab kev sim racks yuav tsum tau ua rau loj batch ntau lawm.
