Damaged APM, I messed up

Posted by Don Cramer on June 17, 2011 at 3:08pm

 

While soldering the pads on a new APM (the 3 filter pads) my soldering iron slipped and dislodged a surface mount component. I thought i would be able to repaid this, i was wrong.

 

Please see the attached photo. The blue arrow points to the component that is no longer on my board. How do i find out what this component was and get assistance fixing this?

 

Any help or advice appreciated.

    Thanks a ton Gerard. Either way, looks like a simple fix.

    Sorry, yes your card is REV H V10 Hotel found here :

    The pad was for enable/disable gyro low pass filters

    After looking at close ups of the traces on the board that with that component missing it is the same as not having the z gyro pads not soldered. So i guess it could be worse.

    Thanks Gerard. Those don't seem to be for the Rev H board (new board) which is what i have. It does not show the pads or that component.

     

    And yeah Lee, tiny. I had control of it for a mere 5 seconds before it was gone.

    That same thing happened to me! Except my iron didn't slip, just the heat from soldering the pads was enough to dislodge that component. The piece is tiny, I almost lost it as well, but was able to finally manage to solder it back on. At least I think so.... Goog luck!
