I made a footprint for a 6 pins SMD led. This led has actually 3 led chip built in so all pins on one side are cathodes and all pins on the other side are anodes.
I design road signs enhanced with LEDs and such those leds are placed all around on a grid less pcb.
Since I always make these leds run in parrallel I made a footprint using the recommanded pattern of SMD pads with no number, (actually a space). Then I made a very long and narrow pad to connect 3 pads on each side with no number again. I then placed 2 standard trough hole pads and these are numbered 1 and 2.
The reason for those pads is that saves me quite some time when routing as I don’t have to start a track, then change side until the destination point where I have to change board side again to join the pin on the component.
This works just swell without problem so far.
BUT… ( there is always something!)
For a design I am working right now, the leds are to be mounted on the bottom layer and the rest of the components will be mounted on the top side. So I ‘flipped’ the leds and placed them where needed.
When I try to route them, the router acts as if I had a rule violation and will not let me place tracks from the bottom side!!??
I have to start on the top side, run a little, then change side, which will place a via automatically, and continue routing the net until I arrive at destination where I have again to change side and finish the track on the top side.
I think I understand what is going on somewhat… It must be creating a rule violation of some sort or it acts like if wanted to start a track outside a component.
I must also state that when I click to start routing a net, I can see the net label as usual.
I must also state that I did not try with other component footprints.
