PCBs yog ob leeg ib leeg (muaj ib txheej txheej tooj liab), ob / ob daim phiaj (ob txheej txheej tooj liab nrog cov txheej txheej nruab nrab ntawm lawv), lossis multilayer (ntau txheej txheej ntawm ob-txheej PCB). Feem ntau txheej txheem PCB tuab yog 0.063inches lossis 1.57 hli; nws yog cov kev kawm qib txheem tau txhais los ntawm yav dhau los. Cov Txheem PCBs siv lub dielectric thiab tooj liab raws li lawv cov hlau uas nrov tshaj plaws muaj cov khaubncaws sab nraud povtseg sib txawv ntawm cov khoom siv. Lawv teeb tsa lub hauv qab, lossis hauv paus, tsim los ntawm fiberglass, polymers, ceramic los yog lwm qhov tsis yog hlau hlau. Ntau yam ntawm cov PCBs siv FR-4 rau lub substrate.Many ntau yam tuaj rau hauv kev ua si thaum kev yuav khoom thiab tsim cov ntawv luam tawm Circuit Board (PCB) xws li profile, qhov hnyav, thiab cov khoom sib txuas. Koj tuaj yeem pom cov qauv PCBs uas siv rau hauv qhov tsawg kawg ntawm tus najnpawb ntawm cov ntawv thov. Lawv lub peev xwm ua raws li lawv cov khoom siv thiab kev tsim kho, yog li lawv lub zog hluav taws xob qis thiab high-end hluav taws xob zoo ib yam nkaus. PCBs ib leeg nyob rau hauv cov khoom siv tsis yooj yim xws li lub cav laij lej, thaum lub rooj zaum multilayer muaj lub peev xwm los txhawb nqa cov khoom siv hauv chaw thiab cov supercomputers.
