Guys I need help, I burnt off the solder points on the lpc, can anyone tell me alternate connection points? thanks.What i am going to do is trace the circuits but it would save me a bunch of time and eye strain if somebody knows
No don't have any drawing i could send .
but on the top side you have
5 with a via right next to it
6 Is the 5V line and is every where
13 & 14 you will have to follow
15 (3.3V) is one side of the cap right above it
on the reverse
1 & 3 you will have to follow
5 you will have to follow the long track back
10 follow back
the rest are to vias pretty close by.
Not easy though..good luck

Stating the obvious
if the iron you have burnt off a lot of pads then its too hot...it will be no good to use it for delicate track repairs.
Get a decent iron for microelectronics work before you attempt the repair

Well it wasnt actually me who f'd up this thing but somehow i got stuck trying to fix it, and I alwready have a 15w pencil tip sodiron. THANKS very much that little bit of help saves me time, thanks again
No problem...not that much help really.
Only thing left is i suggest you do a wire install of the X3 that way you can strip it longer to allow soldering to top and bottom of each pin hole on the LPC.
Ripping off the pads will have definately pulled out some of the thru-hole plates so solder will not run through to the other side.
I think it's only pin 5 that has tracks both sides but all the same wire install will ensure best connection to the LPC top and bottom.
Happy soldering

Yeah my thought exactly, do you know how many go from side to side? I actually was able to repair 3 of the pads with th nail polish trick and conductive pen.
just out of curosity are you using this conductivity pen:
