Top layer pad with hole

ffb.boy.30 over 2 years ago

Hi,

I've an old Altium (2016) and I would like to create a top layer pad with a hole.

Actually, when I create a top layer pad the hole disappear.

My goal is to create a 0.8mm pad with a hole of 0.4mm.

The bottom of my pcb will be in contact with metal that why I don't want to use multilayer pad

Thanks for your help

Out of sheer curiosity, why do you need this hole on the pad? Is it a test point for a multimeter probe or test fixture? If you need a via to get the signal to another layer, why not just tent the via…

I solved a similar problem by just making a NP hole and then on the top layer using the circle/arc placement

and then adjusting the arc track width to the diameter that you want.

You then adjust the arc radius until it is slightly larger that the hole.

You will probably have to then reduce the arc width to suit.

I like your idea. I've tried to create the hole with a cutout but it don't work.

How do you make your hole ?

Thanks

Just make a hole/pad dia. 0.4mm and make sure it is unplated, like an unplated mounting hole.
