A better iBook fix?

[Wireless Buddy]

My iBook G3 has the broken logic board and I'm currently using it with the shim fix, which mostly works, but I'd like to try something a little more reliable (the display still goes crazy is I move it too much).

Would it be a good idea to move the shim from in between the white outer case & the metal to inside the metal actually against the chip?

It seems like this would work better, but I didn't know if this would be too hot and cause the shim to melt or catch fire?

What is your shim made of?

What is your shim made of?

Right now it's a piece of CD, but if I were to move it to inside the metal, I was thinking of using a 3M mounting square.

I was going to recommend a piece of aluminum wrapped in electrical tape, but i'm not sure max temp the g3 reaches. Would the tape melt? Then i'd worry about the conductivity of the aluminum. As far as the 3m square, again i dont know the "too hot" temp for the square.
