Hi guys,
This is not exactly a Laptop schematic but a BGA datasheet request.. I hope its is allowed.
I was looking around the internet but can not find the databook/datasheet for this generation of ATI GPUs.
I am only interested in the mechanical design of the BALL GRID ARRAY (dimensions, pitch, etc) to create a stencil using laser.
I can find similar pdfs here for example:
http://support.amd.com/techdocs/46112.pdf which on page 62 shows the information I need.
The footprint I require is shown in the picture.
Please let me know if you have a PDF for this kind of BGAs (any BGA with this design is OK, 216-083300, 216-0729051, 216-0810005, etc)
br,
george
