I am involved in a project in which I need to create a few
prototype boards that will use the AT91SAM9G20B-CU processor in the LFBGA217_J package.
Because this is a fine pitch
BGA package, I'm not sure how to go about building prototypes that can be populated by hand. One thought I had was to have a PCB
manufacturer create a simple "breakout" or adapter board that contains the
BGA package and brings out the pins in some manner that will allow the board to be fairly easily soldered onto a main board that has the memory and I/O ports etc. Basically I'm trying to find a way to have a CPU board manufactured that converts the
BGA package into a form that is more friendly to use in prototype boards.
I have the ability to solder fine pitch
SMT packages with legs, but I can't deal with
BGA's. I realize that once the prototype board is proven I can have the boards manufactured and assembled by a PCB fab house that can deal with
BGA's, and that is what I eventually plan to do.
Currently I'm laying out my boards using
Eagle CAD 6. Do you have any recommendations or advice for me?
