Ib qho khoom siv hlau luam tawm hluav taws xob tswj hwm hluav taws xob (MCPCB), tseem hu ua tus pcb lossis hlau packed PCB, yog hom pcb uas muaj ib qho khoom siv hlau los ntawm cov board. Cov hlau tuab (yuav luag ib txwm aluminium lossis tooj liab) yog npog 1 sab ntawm PCB. Cov tub rog hlau tuaj yeem siv rau cov hlau, ua ib nrab ntawm nruab nrab ntawm qhov chaw lossis sab nraub qaum ntawm lub rooj tsavxwm. Lub hom phiaj ntawm cov tub ntxhais ntawm MCPCB yog kom thim kev kub ntxhov thiab ua rau cov me me uas tseem ceeb me ntsis xws li cov tub ntxhais hlau me me. Cov cuab yeej siv hlau hauv MCPCB yog siv los ua lwm txoj hauv kev ua kom tiav rau Fr4 lossis CEM3 laug cam.
Qhov zoo ntawm MCPCB
MCPCBS tuaj yeem siv tau rau lawv lub peev xwm los sib sau ua ke diymer polymer txheej nrog lub siab thermal conductivity rau qis thermal kuj.
