Teardowns I've Worked On
Next teardown a Galaxy Minstrel .... or was that just a British thing? They don't melt in your hand (according to the advert anyhow) www.youtube.com
Nothing of interest on the back side of the Board - there is a step (cavity) in the main PCB to further reduce thickness where the flex goes from back to front ...
In combination with the main board high density technology, this is pretty unique, and a measure of the lengths Motorola have gone to with the new RAZR to make it "geet" thin!
