How many layers for package FCBGA

Hi,

Please provide a part number or device family for your inquiry.  In general, this will depend on the number of pins/signals to be routed.  Here is an App Note that might be helpful: http://www.ti.com/lit/wp/spry319/spry319.pdf .

Hi user5235885  ,

I have not received a reply as to the part number or family of devices you are asking about; here are two other references to pcb layout for FCBGA that should be helpful:  http://www.ti.com/lit/ug/spru811a/spru811a.pdf  and http://www.ti.com.cn/cn/lit/an/slda021a/slda021a.pdf.

Please advise if these provide the guidance for layout for your design, or if you have any other questions concerning layout.

Regards,

~Leonard
