Top layer pad with hole

ffb.boy.30 over 1 year 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…

No I just need to solder a wire that come from the other side of the pcb . The wire need to pass throught the metal and the pcb, and the pcb is glue to the métal . It is a led pcb

Given that, does the wire actually need to solder to a pad around the hole or could it extend a bit further to a pad on the board away from the hole? That sounds do-able without stressing the PCB manufacturers. With such a small hole, soldering the wire so close to it could well wick solder down and bridge to the metal plate.

Would it be possible to cut a groove through the surface of one of the blocks sides to sit the wire in (deep enough so it is flush, the wire can’t be too heavy gauge if a 0.8mm hole suffices) and bring it to the top of the board and a pad without using a hole?

Unfortunately the LED is 3x3 and my PCB is a round 5.6.

I've found the solution. Making a circle to create the pad and I will make the hole by myself it is not a problem.
