Tooj liab PCB

Copper PCB, lossis Copper-Based Printed Circuit Board, yog hom kev luam tawm ntau tshaj plaws siv hauv hluav taws xob. Lo lus "Copper PCB" feem ntau yog hais txog PCB uas siv tooj liab ua cov khoom siv tseem ceeb rau nws cov khoom siv hluav taws xob. Tooj liab yog dav siv vim nws cov khoom siv hluav taws xob zoo heev, ductility, thiab tus nqi qis.

Nyob rau hauv Copper PCB, nyias txheej ntawm tooj liab yog laminated rau ib los yog ob sab ntawm ib tug uas tsis yog-conductive substrate, feem ntau yog ua los ntawm cov ntaub ntawv xws li FR-4 (ib tug iav fiber reinforced epoxy laminate), CEM-1 (ib daim ntawv thiab epoxy resin khoom), los yog polytetrafluoroethylene (PTFE, feem ntau hu ua Teflon). Cov khaubncaws sab nraud povtseg yog cov qauv siv photolithography thiab cov txheej txheem etching los tsim cov kev xav tau hauv Circuit Court, txuas ntau yam khoom siv hluav taws xob xws li resistors, capacitors, thiab kev sib xyaw ua ke.
