dear all
i use express pcb programe to make pcb circuit but during design of my circuit which is invertrf i found that alot of lines will interrupt each other what i can do to avold that and gow i can convert the pcb file to print it and how i can make a scaled design
if the board has only one face of cupper i didn't need to drill in the boardto put the component as the component will be connectedon the upper surface which has the cupper lines is it right or not
please the question may be trivial but i need to replay as it is the 1st time i try to make a pcb circuit
thanks
