Can a Ranger have more than one Archtype?

[Exterminator]

I wanted to play a Infiltrator/Skirmisher. And If I have skills in Craft(trap making) Shouldn't I be able to make some of the Ranger Traps?

You can have two or even (rarely) more archetypes. The only limit is that each archetype must replace different class features.

As long as the archetypes don't replace the same basic trap feature you can take both.

These two would not be an issue.

You have to take the "Learn Ranger Trap feat" in order to make the traps. You can't craft them.
