Talk about mod-ing and building franken-laptops
I attempted my first reflow on the GPU of the first T40 motherboard. I took 25 minutes to get it slowly up to 250C and then back down slowly. I didn't touch it until it reached 25C a half hour after I took the heat gun all the way off of the chip (around 150C).|
After pulling off all the tin foil it seems that the motherboard is fine underneath, and all the little molex/plastic plugs are none the worse for wear. I was worried about that. 250 degrees Celsius is FREAKING HOT -hot enough to melt solder, natch.
Now that it is cooled down I can look at the solder balls from the bottom of the chip and they don't look too different but I can see just the slightest bit of new shiny solder on a few of them. If some melted then they all did. Looks like it's good to go for an attempt to put it all together and try to boot it up.
If I got lucky and Vulcan has smiled upon me I will be elated that this worked. Taking a $15 parts machine and turning it into a fully-operational battle station laptop will be a feat that children will sing about in epic ballods for generations.
