I am a student making a project on PCBs ,and i have a small question .
The schematic i want to map ,has many Plugs (both male ,and femlae),and solder points,and connectors (like the EBC15DCWN).
Is it necessary to make a footprint of these parts before going to layout ,or is it only a part of the mechanical layout ofthe board ,and can be added later ?
Can anybody guide me as to how to make the footprints ,or otherwise ?
Thanks in advance !
Take a look at:- http://www.youtube.com/watch?v=wfCM0Ho8IE0
Okay,so just to clarify things a bit more.
The schematic includes soder points,and male and female connections which are to be incorporated.
My point is :-
Do i need to make the footprints before going to layout ? and if so ,are there predefined footprints for parts like these ? or do i have to custom make the footprints ?
You will need the footprints in order to layout the board. If you do a search on your computer for "*.llb" you can find the location of sample libraries provided by Orcad. It should be under Orcad\orcad_xxx(<-your version)\tools\layout\library. When you open Layout, select Tools\library manager and add any necessary libraries. Search the libraries and see if you can find a footprint that meets the manufacturers recommended footprint. If there is no footprint close to what you need, you will have to create it yourself. I also suggest running the Learning Orcad Layout tutorial under the help tab to help you understand what you may need to create.
