Default PCB quick disconnect tab

I'm building a new amp and this time around would like to solder on tabs rather than wire directly to the board.
I purchased some of these but the holes in the PCB are not big enough. I could go for something like this but then the surface area for the connection is much smaller.
Does anyone know of a connector that will do what I require and still retain the larger surface area?
Thanks,
Dan

Excuse me for stating the obvious.

Why not just enlarge the holes slightly ?

Or take a needle file to the pins to make them smaller ?

The single pin part should be able to carry 6 amps. Your limit is dictated by the solderjoint, not the quickconnect. E

Can this be done? Is there a risk of lifting the trace?
Thanks

If the solder pads are fairly large and you are reasonably careful then yes.

If you are in doubt just make the connector pins smaller with a file.

I like using screw terminals like this or this. This seller also operates on eBay here or here. You can get simlar terminals from Mouser or Digi-key also, but you will likely end up paying a lot more. I am not affiliated in any way.

Spade terminals are known to corrode in time unless they are Gold plated.

You'd also need Gold plated recepticals. Nothing super expensive there as they are commonly available at a reasonable price.

Screw terminals do seem to last the test of time better.
