Printed Circuit Boards (PCBs) yog cov khoom tseem ceeb hauv cov khoom siv hluav taws xob. Lawv nyob hauv lwm cov khoom siv hluav taws xob thiab kev sib txuas sib txuas, muab qhov chaw ua haujlwm ruaj khov. Circuit configurations yuav broadly categorized ua peb hom:
[Ib leeg-ib sab PCBs] Hlau Circuits rau cov khoom sib txuas yog nteg tawm ntawm cov khoom siv insulating substrate, uas tseem ua haujlwm pab txhawb rau cov khoom siv.
[Ob chav-sab PCBs] Thaum lub voj voog ntawm ib sab tsis txaus los txuas cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tuaj yeem teeb tsa ntawm ob sab ntawm lub substrate, nrog los ntawm - lub qhov hluav taws xob muab los txuas cov circuits ntawm ob sab. Rigid PCBs yog tsim los ntawm cov ntaub ntawv xws li cardboard, fireproof board, thiab fiberboard. (Lub npe Askiv: FR-4)
[Multi-txheej PCBs] Rau ntau daim ntawv thov, circuits tuaj yeem teem rau hauv ntau txheej, laminated ua ke, thiab dhau los ntawm - lub qhov hluav taws xob yog muab nruab nrab ntawm cov txheej txheem los txuas cov circuits.
