COMPONENTS OVERLAP DRC

ColinLiu

Hi expert,

There is special case that I have to overlap two components  to reserve two kind of footprint. 

I can understand the overlap DRC error on this case.

But there are still two other DRC type I do not know how to deal with.

One is rats: It seems just can be route/connect to one symbols pin while another one is can not accesible. So the rats exsit.

Am i should route all the two pins in different components? It seems i can not do it. How should I deal with this DRC error?

Another one is: Drill hole to line same net spcaing(because the footprint is dirllhole)

I guess this error is caused by the line and another pin which I do not connect.(I try to delete one symbols footprint and this DRC disappear)

How can i deal with this kind of error.

I think there are some cases that you have to reserve two footprint. Please teach me some about it. Thanks

    My suggestion is to make 1 footprint which does not have any padstacks, so basically a mechanical footprint. Then you can overlay these 2 footprints without any pin/connection issues.

    In one case I had to place 2 TH transformers 90deg. rotated on top of eachother and only 1 pin was matching in location. So In 1 component I added 'unfix pins' property to this pin, changed the padstack to a SMT testpad and moved it away from the pin which was already there (from the 2nd component). 

    Kr, Bram

    I think your method must be workable.Thanks
