Are there cost effective ways for hobbyists to solder BGAs? I remember back in the day, it wasn't that expensive to get an etching kit and create some single layer prototype boards but they all used through hole components. Now-a-days it doesn't seem like that kind of stuff is possible anymore.

A lot of people will insist you absolutely need a massive multi-thousand dollar peice of kit, but its nonsense, and gear of that grade is only of much use if you are doing large batch jobs and you want to minimize your failure rate, for one off projects a few percentage points either way in terms of failure rates is completely irrelivant, especially considering you can just rework it anyways. if you want to go the full 9 yards though, you could spring for something like this and get real professional level results, for around $300ish USD + a little DIY. http://www.whizoo.com/ http://www.whizoo.com/ And in regaurds to the boards themselves, its true you cant very easily make 4 layer PCBs with Vias and other sensitive alignment constraints at home, however the good news is that they can be ordered even cheaper than it would typically cost a home maker in materials for even single sided boards!. https://dirtypcbs.com/store/pcbs https://dirtypcbs.com/store/pcbs https://pcbshopper.com/ https://pcbshopper.com/
