through pin but not hole within it

[yakex]

hi,
the package of GALI-52 is SMD type of SOT-23, but now I want to
develop a through mounted package for it, i.e., the pins are through
pins, but without hole within it, and GALI-52 is mounted on the top
of the particular pins, is that OK?
the software is cadence v16.2.
thanks.

what did you mean?

I think that is what he meant too.

Can you try and explain what you want to do differently?

If I understand correctly he just wants to add small vertical pins between the smd component and smd pad on the PCB (without any holes in the pcb), he will just raise the component a few mm.
I don't know how easy it will be to keep these pins in place because when you try to solder one side the solder on the other side will melt too.

I am sorry for the confuse.
I want to develop a through pin for Surface-Mount-Device. The through pin is like a circular cylinder, and it go through all the layers. The SMD will be mounted to the top surface of the circular cylinder.
In the above case, the route can be placed on the internal layer of the PCB board, and the devices are mounted on the top layer of the PCB board. Also, there are two planes on the top layer and bottom layer of the PCB board. I thought there would be much less radiation and less cross-interference between adjacent channels.
Is that possible?
thanks.

you can do that but i don't think that is a good idea (for connection) , yo can make SMD pad for and you can do via on pad option ..no need to go with chaining the footprint.

Yakex,

If I inderstood you correctly, you can achieve what you're describing with help of a little adapter PCB. This PCB has SMT pads for your component, which are connected with traces to throughole pads. Then your pins (pillars) connect to holes on the main board.

By the way, if you post a sketch, that will help.
