Hi guys, i have a hobby cnc board on the way, and i was just wondering if a 25 watt soldering iron would be good enough without causing any damage to the components.

That will work just fine.

With irons my preference is to always go over rather than underate, as with a large wattage the time taken on a solder connection is reduced, rather than having to keep the iron on the connection for an extended time in order for a good solder flow, this tend to put more stress on the components.

Totally agree with Al on this. I have a 17W iron that I really don't like. Even when used with SMD components. I prefer to use a 25W iron.

A high wattage iron connected to a dimmer switch works well.
I had that setup for years. If cost is not a problem, I would really recommend a temperature controlled iron. I bought a Hako 900 tip but made my own controller. It is so convenient to have something that is ready for use 30 seconds after power up.
