Hi,
I am looking for a free ware that allows me to construct the schematic and import the netlist to PCB layout for track routing, I don't need more than 2 layers. However, I would like to be able to assign/change the pin number to customise an opamp in case they do not have the particular op amp in their library. Does anyone know of a freeware that can do this or any program that has this feature? Any suggestions?

Thanks in advance!

Re: PCB freeware??

Hi,
Yes, I have that program and am still using it but it does not do what I need to do eg. create schematic and trasfer the netlist for PCB routing. Also, the program is unstable on 98 things go funny after 40mins -1 hour of use eg. part of the circuit not displaying properly etc.... therefore you need to save regularly in case it does crash.

Re: PCB freeware??

I don´t speak english as my main language so I don´t understand your question very well. What functionality do you need? For example... what else do you need that expresspcb don´t have?

Re: PCB freeware??

Thanks a lot for the link and suggestion, I have not yet tried this program but will do to see if it does what I need.

Just to clarify again about the function I am looking for, I have some op amps which are custom made from Toshiba for car stereos and I am looking to use these in my circuit. Since these op amps are not standard ones, I was afraid that I can not find them in the part library of the program to draw the schematic so I would need to specify the pins on the op amp to match the op amp I have. I will check out the program to see if it allows me to customise an op amp and specify its pins, thanks again guys!

Folks,

Since you have mentioned the ExpressPCB, I'll add that there is an unofficial support group for it. The main goal is to share the custom schematic and PCB components and PCB design tips.

Sincerely,
Nick

Re: PCB freeware??

did you try pcb123, it is a very user friendly program which can do what you want easily.

Cadstar express has a 300 pin or 50 component pin count & is fully featured otherwise, including the router.
