Kimmo, how is the PCB attached to the plastic? Glue? Double-sided sticky tape? Magic?

I had the crazy idea of using the empty space in my new TOH to fit a Qi charging pad. I found one that is cheap as chips and fits almost perfectly, though I may need to remove one of the ribs. But my main problem is how and where to attach the power lines. Obviously I would prefer to attach them to your PCB as that already has the pogo pads but it sits in the plastic like a bum on the potty. How do I take it off without breaking anything?
