Component footprint terms
Component footprint terms
(OP)
I was talking with a friend of mine the other day about component footprint verses component body size. He said the footprint is the body size, it this true? I always saw them as being different.





RE: Component footprint terms
From a mechanical standpoint, the footprint is indeed the body size... the component takes up whatever space it takes up, plain and simple. That is, by definition, the footprint of an object.
From a PCB pad layout standpoint, it depends on your method of soldering (wave, IR reflow, hand, etc.). In the case of wave soldering, it also depends upon the component orientation compared to the flow direction of the wave.

Hope that helps!
RE: Component footprint terms
That is my understanding also. I guess it depends. If it is the CCA, it is the component body. If you are looking at the PWB, it is the actual connections.

RE: Component footprint terms
IMO a good footprint file will include both pad pattern and physical outline.
