Negative side for Battery clips on perfboards?

Other Hardware General Electronics
1

I'm looking to solder a thin battery clip like this onto a perfboard: coin cell battery holder. But I'm confused about how to use it. As it says, "Metal housing is +, PCB pad underneath is -." So the battery holder itself connects to the positive side of the battery, but what do you use for the negative side? Is this only used for printed circuit boards where there is a preprinted battery pad for the negative side? Or can it be used on a perfboard, aka a dot pcb.

I found one example of someone using one of this on a on a perfboard:

"Have a look at the battery carrier as well. The part number is in the Parts List; I simply mounted it on a bit of perf board and ran a couple of wires to the main PCB. I put a small square of copper tape with some solder on it in the center of the perf board to serve as the negative post. Note the hot melt glue which provides strain relief and prevents fatigue failures of the wire."

Is this the standard way to do it? I'm just wondering if there's a little component I can buy instead of a whole role of copper tape (that I'm probably not going to use ever again) or any other alternatives.

I'd think you could just add some solder instead of the tape. I'd definitely use the plated through hole style of perfboard rather than the type that just has surface pads on one side.

OK thanks, that's helpful because I didn't know there where perfboards where the holes were plated too.

The one in the picture is plated through hole. Usually they will be green boards with silver tin plated pads.

The single sided ones are usually tan boards with unplated copper pads:
