Hi all,

what meant by Trace?
Trace and metal layers are equal or not?


Thanks.........

Metal layers contains trace... a track you can saw... so traces are "carved" out from whole metal layer to provide signal path to destination

can you explain briefly please...........

in order to get signal from one point to another u use wires in bread board or veroboard.. in pcb you do this by copper tracks called trace.
if you have seen a pcb the bottom side full of copper is the metal layer .. you etch or carve out traces from this layer
i can't be more brief
