This is probably a stupid question but is there any way for a "hobbyist" to
use BGA's? If I were to etch a board, tin it, apply some flux, sit BGA IC on
it, and put it in an oven, would I get brownies out? Just wondering if its
possible to do as some of the things I'd like to use involve BGA's.

Thanks,
Jon

Yes it's possible, some people have had success with using toaster
ovens, like this:

Google "bga toaster oven"

But the best advice is to simply steer clear of BGA for home use if at
all possible.

But if you want to try it yourself, spring for a proper solder masked
PCB, they aren't expensive.

Alternatively, get a tube of BGA chips, some BGA-to-throughole adapter
boards and an assembler to put the BGA's on the boards for you.

I'm getting a small BGA mounted on a couple of prototype boards, it
isn't a hobbyist project. My client is paying 300 GBP for the work,
but that includes a stencil, assembly and X-ray. They have to use
solder paste because the solder balls aren't uniform and some are non-
spherical. If the balls are OK home assembly is feasible (no solder
paste is required), but I wouldn't have risked it for this project.

Thanks, atleast I know its possible. I doubt I'll be able to use them
because I can't do multi-level pcb's which kinda makes them useless. I might
look into the adapators though.

Jon- Hide quoted text -

My board is double-sided, but the BGA is a Telit GSM/GPS module with
only 84 balls, most of which are around the sides.

The ones I'm dealing with are 256 or something like that but most of the
inner ones are for grounds. I'm sure its not all that difficult with enough
time and experimenting but I'm going to try and avoid messing with it for
now... atleast until I get more experienced with SMT.
