<p dir="ltr">Yes, a TH pcb will be able to hold a daughter pcb just by the through-holes, whereas SMD pads will not hold one. So you can easily change topology using an extra pcb on a TH circuit but not on an SMT circuit.</p>

Through hole is the same, if you want new traces you make a new PCB. Or<br>
you can use mod wires.<br>
You can use modwires on SMT too, they're just a bit smaller :)<br>

I don't follow.<br>
You're saying a through hole PCB has more structural integrity than an<br>
SMT PCB and that an SMT PCB can't hold a daughter PCB?<br>
