BGA definition

Post by VTiederle » 02 May 2019, 22:59

How can I define the BGA layout e.g. for a DRAM? Here there are 4 sectors, a little bit separated from each other.
As example see the package 200-Ball WFBGA – 10mm x 14.5mm (Package Code: NP) from Micron.

Best regards
Viktor

Hi Viktor,

Could you please provide an example image of the BGA of interest?

Hello,

If you have a Netlist associated with your BGA, the Netlist option (under the ball tab in the Parts Properties Editor) would model the exact BGA ball pattern.

If you do not have a Netlist for your BGA, then the recommended approach is to use the ball patterns available in Sherlock to approximate the layout.

If you have any further questions, please do not hesitate to ask!

Hello,
it should work if the netlist option. Unfortunately the parts is rotated by 315°.
By applying the netlist option the balls are generated not correctly (not rotated pattern).
Unfortunately I was not able to copy a screen shot to this post.
Hopefully it is clear, what I mean.
Best regards
Viktor
