We found a single company that made only one size and they are $20 a piece, just too much since it usually takes 2-3 attempts to solder the BGA successfully! So, I just whipped up this 6x5, 30 ball BGA adapter with 0.5mm ball pitch spacing. The photos show a blank PCB and one where I mounted a 4x5 pin BGA. It's NOT easy to solder these, align them, its very much trial and error and I have the benefit of a BGA re-work station, reflow over, hot air station, and industrial microscope. But, if you want to use micro BGAs (or have to) then this is your only real option for prototyping, you must make a PCB to mount the BGA, then wire the BGA up.
I will post a video later showing how I mount them as well for reference. We also have another version coming in that uses a different technique (vias) instead of pads for the BGA to see how that works as well.
The product will be up shortly, I am think we cut the competition's price in half and they will sell for $9.99.
The first batch of "micro" BGA adapters
The first batch of "micro" BGA adapters we just designed came back from manufacturing. Basically, a simple PCB that you mount your micro BGAs on. Then the signals are routed out to a DIP inline header at 0.1" pin spacing with 0.4" distance between signal rows. If you are going to try and do any type of designs that require micro BGAs then you will need something like this.
