The tinning IS very important.

As I posted in one or more of the other threads on this, my ultimate conclusion was that some of the connectors used in the N900s were either:
  • improperly tinned
  • not tinned at all
  • tainted by some residue
In hindsight, that's the most reasonable deduction based on the findings of everyone involved. It explains why some connectors fail easily and why others never fail at all, even with abuse (properly tinned).

Ultimately, the fault lies more with Nokia's component supplier than with Nokia. This problem could have even slipped through Nokia's AQL sampling. It happens.
