I've had to do this quite a few times, but I never thought about wrapping a conductor on the soldering iron tip to essentially make a smaller tip. That's pretty clever!

Hi Scott,

Thanks for sharing your technique for doing what is suppose to be impossible. This should be the definition of an Engineer. See a problem, formulate a way to over come the problem, build the tools to make it happen, and then do the impossible. By the way how did those other 5 wires go?

The big challenge was to actually get samples from NXP : )

You've made the rest look easy - very nice, clean job! The idea of super-gluing kynar to make

a custom super-slim ribbon cable is very inspired.

Still amazing to think that the distance of the outer wires (blue to the red) in your last photo is just 1mm..
