Of course it makes sense, because it is a thru-hole part so it needs
some kind of pads on both sides.
On one side, the pad size could be almost zero but the hole is still
there and needs to be accounted for when routing.
Otherwise it is a surface mount part and the router does what it did for
you the first time.

I HAVE to put pads on both sides!
even if I solder only on one side (!)
that I just understood: when a pad is on both side, the pad of one side
is connected to the pad on the other side .......!
am I right?
I guess yes...
I hope it will help, one day :)

hello,
I'm using freerouting. net to autoroute my pcbs for the protodeck
project I began.
at the beginning, I created my modules but I did a mistake: I put pads
for leds, for switchs and for headers on the two side!
But I only want to solder on one side (bottom side for leds + switches
& upper side for the headers ; cause components leds & switches will
be on the upper side and the header under...)
So... I launched the autorouter and ... here is the result I numbered
1, 2 or 3 things in the attached picture.
the blue traces are the traces which are on the bottom side (to
connect switches, leds) on 1, 2 or 3, there is another red traces at
the same place, but there is a hole and a switch leg inside ...
is there a mistake? an error ? a bad understanding from me ????
please, help me :-) Julien
