If Nokia are relying on such engineers to allow such usb port design to pass protortype stage then it sure needs to investiate fully who they got working in their design team.
The decision was very likely made higher up than the PCB design engineer. And odds are that testing (a separate function) was not rigorous enough to expose the problem.

The point i was trying to make is something you would very know about and that is how can any design engineer even allow this design to go past him without realising its defficiency himself so if your saying it went to an even higher level to get past quality then it just goes to show big holes exsist in the Nokia quality control dept.
Texrat you and me both know and in unison here that this is no way an acceptable usb port fix to the main board and that alone does not even need to be tested to know its just not capable of staying on the board under such conditions, and also taking into account this is in fact the only port for charging and data flow so is obviously going to get rigorous use.
Just makes you wonder what goes on inside Nokia to oversee this blunder !.
What REALLY pisses me off is how Nokia are even attempting to put the blame back to end user for this, it IS their design fault and to even read just one case of repair rejection is furiating to say the least.
Nokia should well have acknowledged by now the flaw and passed a memo down to every single outlet or repair centre for immediate replacement or repair with NO quibble and no argument to customer in any way.
Incidently i do have a complete fix for this but is pointless even putting it on here for obvious voiding warranty reasons, it is a simple u plate with lugs soldered to the port itself and lugs soldered both sides to the main pcb and if i am not mistaken here even a hole can be drilled through each lug with a case rivet at least through either lug, that would be a complete fix that would make sure the usb port could never leave the board or even become loose (same as the older port design by Nokia on previous mobiles).

You're missing my point.

I'm betting the design engineer had little control over component selection. I'm betting someone farther out and higher up from that role had ultimate say-so. That's based on both my own experience as a former PCB designer, product designer in general, and a former Nokia employee.

As for QA, it's not a single department. QA is broken down by functions and sites. The Nokia QA team I worked in did outstanding work-- the proof was in our exceptional on-time delivery combined with low field failure rates. I cannot speak for other Nokia QA teams.

So are you telling me that the selection of usb ports to be used on the N900 design is the one and only port that was used? could he not implement or ask for a change of port type (knowing how it ended up).
I know all about cost effective design but this is rediculas to implement that type of usb port on the m/b because i know from my own experiance to pick and place THAT design of usb would never end up with the minute solder plates it has, it would have had much bigger surface area to adhere too so someone is very guilty here because around that port is a very large empty area on both sides thats painted so they obviously cut out the plating area needed for that type of usb socket, problem is i dont have a pcb track layout only the schematics so i dont know what is under that paint but i do know if that was my design i would have been fired for that to end up as it has!.
As for failure rates of Nokia mobile devices ... hmm no comment lol.

If it can be proven that it is a defect that existed at the time of purchase (which IMO it is, as it is an unfustifiable design) then in the UK/Europe I believe that protection extends up to 6 years -- whatever one might regard as reasonable for the lifetime of the device.

I guess NOkia could argue no-one expects a phone to last > 2 years these days - but based on other phones going on and on that I'm sure could be challenged.

So I'm being careful, but not getting too worked up about it. If it happens I'll worry about it. Not a lot else one can do except sell up,

I am thinking about the previous 5800xm earpiece problem which was acknowledged by Nokia ONLY after they finally found a way to fix it.

Please re-read my post for what was actually stated.

My statement stands. Field failure rates from *our* facility were very low.
