Lub Printed Circuit Board (PCB) yog ib qho tseem ceeb hauv cov khoom siv hluav taws xob, ua haujlwm rau kev sib txuas thiab lub cev txhawb nqa cov khoom siv hluav taws xob. Nws lub luag haujlwm tseem ceeb yog kev sib txuas hluav taws xob sib txuas ntau yam khoom siv-xws li cov resistors, capacitors, thiab kev sib koom ua ke- ntawm cov kab hluav taws xob uas tsim los ntawm kev sib txuas ntawm cov ntawv ci tooj liab, thaum tib lub sijhawm muab kev txhawb nqa txhua yam. Rau cov ntaub ntawv tseem ceeb txog cov khoom no, thov tso koj cov ntaub ntawv tiv tauj, thiab peb yuav rov qab rau koj sai li sai tau.
PCBs yog ua raws li cov qauv sib xyaw ua ke uas muaj cov txheej txheem hluav taws xob (feem ntau yog tooj liab ntawv ci) thiab insulating substrates (xws li FR-4 epoxy fiberglass, polyimide, thiab lwm yam). Los ntawm cov txheej txheem xws li tshuaj lom neeg etching los yog laser ua, cov qauv Circuit Court raug tsim los ntawm cov qauv no los pab txhawb cov teeb liab kis tau tus mob thiab kev faib hluav taws xob.
