Replaced The Mcpx
Posted 18 September 2005 - 04:15 AM
So I had a broken motherboard from a customer who tried to install a cheapmod on a 1.3 motherboard and used the MCPX lframe. They broke the trace and a couple surrounding traces, and the Xbox obviously didn't boot.
I had another nonworking motherboard staring me in the face with a good MCPX, so I figured, "why not?"
I don't have BGA equipment, but I removed both the good and bad MCPX with a SMD hot air nozzle, cleaned up and prepped the BGA points on the board and chip, spent a few minutes making sure everything was lined up, and heated the MCPX back up with the hot air nozzle.
It's hard to judge when the solder has reflowed when you can't see it under the chip. But I took a guess, after a couple dozen seconds of hot air, let it cool and tried booting the mobo with transplanted MCPX.
OMFG it booted!
I WISH I'd taken pictures throughout the process, but didn't think it would work. Maybe for my next transplant!

Anyway, I still don't trust this mobo 100%, so it's become my "loaner" Xbox...

Ya but you need gasoline and ice cubes.
...Anyways, nice job perplexer, I don't even like dicking with lframe, I can't believe you replaced the mcpx. Cheers

Somethings currently wrong with my rework kit at the moment, the hot air is hot, but its not heating up to full temprature like it used to, it melts solder alright but it seems a little 'low on power'? i think theres more than one heater in the gun, i think probably one has failed or is on its way out, ive checked the filters and everything seems fine.
Do you have a pic of the board after youve soldered it back down? i'd be interested in seeing a pic of the final job.
