Crimp directly to PCB (or holes in PCB)
You did not provide any requirements, and it does not look like you've done any research.

Nevertheless, there are several options available. For example for low power you can use so called "card edge" connectors, like EdgeMate series from Molex. For high currents there are Han-Fast Lock terminals from HARTING.

But really, if you consider the cost of connectors, crimping tools and contact reliability, your best option will probably be a simple and dirt-cheap ring terminal either bolted or riveted to large circular pad on PCB.

Note, that this is not the best option in general, I would still go for good ol' screw terminal. A bit of soldering, but beats the rest in convenience and peace of mind.
