Printed circuit board (Printed circuit board, hu ua PCB) yog lub substrate rau kev sib sau cov khoom siv hluav taws xob, thiab yog cov ntawv luam tawm uas tsim cov ntsiab lus sib txuas thiab cov khoom luam tawm ntawm cov khoom siv dav dav raws li kev tsim ua ntej.Lub luag haujlwm tseem ceeb ntawm PCB yog ua kom muaj ntau yam khoom siv hluav taws xob tsim ib qho kev sib txuas ntawm kev sib txuas ua ntej, ua lub luag haujlwm ntawm kev sib txuas lus, yog qhov tseem ceeb ntawm kev sib txuas ntawm cov khoom siv hluav taws xob.
Kev tsim khoom zoo ntawm cov ntawv luam tawm Circuit Board tsis tsuas yog cuam tshuam ncaj qha rau kev ntseeg siab ntawm cov khoom siv hluav taws xob, tab sis kuj cuam tshuam rau tag nrho cov kev sib tw ntawm cov khoom siv, yog li PCB hu ua "niam ntawm cov khoom siv hluav taws xob".
Tam sim no, ntau yam khoom siv hluav taws xob xws li khoos phis tawj tus kheej, xov tooj ntawm tes, digital koob yees duab, cov cuab yeej hluav taws xob, tsheb satellite navigation devices, tsheb tsav tsheb thiab lwm yam khoom siv hluav taws xob, txhua yam siv PCB cov khoom, uas tuaj yeem pom nyob txhua qhov chaw hauv peb lub neej niaj hnub.
Nrog rau kev tsim qauv ntawm ntau hom kev ua haujlwm, miniaturization thiab hnyav hnyav ntawm cov khoom siv hluav taws xob, cov khoom siv me me tau ntxiv rau PCB, ntau txheej txheej tau siv, thiab kev siv qhov ntom ntom ntawm cov cuab yeej kuj nce, ua rau daim ntawv thov ntawm PCB nyuaj.
PCB khoob Board los ntawm SMT (nto mount technology) qhov chaw, los yog los ntawm DIP (ob chav nyob rau hauv-line pob) plug-in plug-nyob rau hauv tag nrho cov txheej txheem, hu ua PCBA (Printed Circuit Board Assembly).
