I read your scorps are 4-5th instar? This is too early to mate them..
When they get adult, you can try to have a go.
You can put the male in the females' tank. Put a slate or hardrock somewhere where the male can put his spermatophore on. He will promenade a deux / coach her onto the hard piece of stone or wood, fertilizing her. So you dont have to do much, but wait and see.
You can also introduce both of them in a new enclosure, with a piece of slate installed in the middle. It is not needed however. Keep the temperature a bit hotter to promote breeding behaviour.
If she wants to, he will find her with his pectines.. but as I said, they need to be mature..
