Through Hole PCB - Traces?

I've got a through hole PCB (one of them that has millions of prepunched holes). I've used them before with typical jumper wire to move off the breadboard.

I've got a problem - MOSFET on one of these PCBs, they typically require more current than a bit of CAT5 cable will accomodate.
Any thoughts?

Go over the traces with tinned copper wire to reinforce them.

If you feel you need more than just tinning them as suggested by Mike, you could do one of two things. Either lay a piece of uninsulated (solid) wire on the pcb that follows the trace and solder it in place, or use a piece of insulated wire and solder it so it’s ends join the devices that source and sink the current you want handled.

Use heavier wire.

For really heavy current you use the PCB just as a convenient substrate to solder
both the component and its wire to, rather then push current through 35um thick
copper foil! You can have the wire go through holes next to the component and bend
the strands over to meet the component's lead and solder them together. The board
keeps leads apart and provides mechanical support only.

There are online trace-width calculators that can help you decide. Remember heat
goes up as the square of current so a doubling of current is 4 times the temperature
rise. 10A is a lot different from 5A, for instance.

Sending it through a PCB is pointless.

Add some thick wire directly from the MOSFET to wherever it needs to go.

You forget that the gate drive signal isn't high current and can be routed on the PCB
even if the source/drain circuit can't be. PCBs make everything neat and putting a wire
through a hole before soldering really reduces the risk of a dry solder joint as there
is proper mechanical support as the solder solidifies. And lastly you can put print
or writing on the PCB to document it.

Ahhh, I was aiming for terminals - I suppose I still can, just take the lead of the MOSFET to the terminals..

Thanks for the ideas! I'll some thick insulated copper wire to go to the terminals, and solder to the board for mechanical support.
