That damn 3.3V

[Iceni]

XboX 1.6 Crystal, X3 chip.

Anyone have any good tips on this one? I've been thinking about wiring around instead of using the LPC (pin 15) connection, since this is the 2nd time in about 2 weeks it falls out. Seems like pressing the chip down too hard or transporting it everywhere is not good for this point. Everything else including the dreaded 5v point works like a charm

Anyone got experience with this sort of problem?

Something is defiantly wrong with your soldering if a pin can fall out. With a good solder job where the solder fills the hole and touches the pin, it should be nearly impossible to make a pin fall out without stripping out the lpc pad as well. Check your soldering job and make sure you completely fill the hole around the pin.

Exactly the solder must only be resting on the pins and not forming a good joint.
Apply heat to it and suck out the existing solder on 15...

wet the iron tip (apply just a small amount of solder)...place the tip so that it touches both the header pin and the solder pad.
Apply fresh solder to the pin (not the iron tip) ...and watch the solder get sucked into the hole..that should fix it for good

If you apply solder to the iron tip u simply melt excess solder over the hole which cools instantly and does not make the joint...

Wow, excellent. That fixed it!

That hole sure took a lot of solder
