Thank you, I am not sure if we have this.
We have B4860 Pinout Ballmap.xlsx you could use, I need to do further check internally if we have better suggestion.
As this is NDA required, please contact Sales or authorized distributor directly to get this, ask him to contact me if he could not locate this file.
Or you can submit SR to technical support, let me know the SR number, I could send through it, but you still need to ask Sales to confirm with me about your NDA first, as this is the policy.
