Yes, a rev A5A BBB with 16G eMMC !!!

OK, so I purchased three BBB cards quite some time ago and I just got back to them since I had some project ideas. So, apparently 2G eMMC chips went EOL and the new cards have 4G. No big deal, except for any newer image available wants the additional space! I built some of my own console images for a while, but then I saw some Sandisk 16 GB eMMC chips on Ebay and scored them for about a buck a piece…

I’ve done some SMT work at home, but NEVER a 20 mil pitch BGA. I do have a cheap chinese hot-air station and a dedicated toaster oven for my hardware play though. I use a coffee mug warmer for bottom heat.

Well, it took me several trials and two of the eMMC chips to dial the process in, but I succeeded! The only real casualty is that I discovered that the 5V input jack will not tolerate re-flow temperatures. I had to replace that part.

I am just amazed I was able to hand-place that chip.

If you are yawning now — well, OK – I am excited about this and had to tell SOMEBODY!

I can truly appreciate that success. Nicely done!

I felt great when I soldered this one by hand (with thermal pad underneath):

and this one (more thermal pads):

Not as hard as BGA, so I can only imagine what that's like.

How much to swap the eMMC on a single board?
