Upgrading An Old Macbook With an Old Processor
My first attempt at desoldering a BGA chip and it worked really well. Chip cleaned up nicely as well.
Disclaimer: I don't plan on using this chip or board again. So, I don't need it to work at the end.
I tried desoldering using my Hakko FR-300, but the tight holes made it a difficult process, and I destroyed a (nonessential) pad even after reflowing it. After doing some research, I found that adding low-temperature solder (here, ChipQuik SMDLTLFP, melting point 138C/281F) did the trick. I was able to set the desoldering gun at its lowest setting, and ended up with clean holes.
Occasionally I'd have to go onto the component side of the board and reflow one of the power pins again, but in the end it was pretty smooth. Wiggle the pins a bit to unstick them, and they come out with only a little persuasion.
Finally got a Hakko FR301; Japanese version that I am going to convert to the US version cheaply. VERY excited to use this.
New video! The pump in my ZD-915 desoldering station stopped working! Let's investigate and try to fix it!

Flying to Hotlanta today for a conference. Decided not to bring a radio and to just tune around on websdr. If I have any free time, priorities will be learning about WSPR, WSJT-X & Olivia and desoldering SMD IC chips.
I’m receiving WSPR signals but my tx is not being spotted. Got a qrz-unknown callsign on a boat just north of Dominican Republic on the tropic of cancer yesterday!
This seems like an awful lot of work just to upgrade an old #XBox, but the process of #desoldering an old #CPU and #resoldering is fascinating!
It's like watching Bob Ross paint, he makes it look so easy!
