Lub rooj tsav xwm luam tawm (PCB) yog lub hauv paus qauv siv los sib sau ua ke thiab txuas cov khoom siv hluav taws xob rau hauv ib qho kev sib txuas, uas tso cai rau cov hluav taws xob ntws ntawm lawv. Feem ntau, lub hauv paus ntawm PCB yog tsim los ntawm cov khoom siv tsis sib xws, txawm tias cov ntaub ntawv hloov tau yooj yim lossis hybrid rigid-flex cov ntaub ntawv kuj tseem siv tau. Cheebtsam xws li diodes, inductors, thiab transistors yog txuas rau lub rooj tsavxwm, nrog rau cov kab hluav taws xob (kev coj tus cwj pwm) pab txhawb kev sib txuas ntawm cov khoom siv no.
PCBs yog ib qho tseem ceeb rau yuav luag txhua yam khoom siv hluav taws xob niaj hnub no, los ntawm cov khoom siv niaj hnub xws li laptops, ntsiav tshuaj, smartphones, thiab smartwatches, rau cov khoom siv hauv tsev, kev lom zem, thiab IoT cov khoom siv. Lawv kuj tseem ceeb heev hauv kev siv tshwj xeeb, xws li kev sib txuas lus thiab kev siv tshuab, kev siv tshuab, khoom siv kho mob, nrog rau tsheb, dav hlau, thiab nkoj.
