@petrockblog Thanks for the info!
I don't have a Hot Air Rework Station, but I may be able to get my hands on one at work.
Can I just ask, what are your thoughts on the Kynar wiring in the link-would it be suitable? And one thing I cannot find the answer to (unless I have over looked it): how much height does the Powerblock add to the the Pi, just incase I decide to go for a new one?
Cheers,
Dan
