Hi

We need to design a PCB with a 300um pitch BGA component. Please have a look at the attached image showing the footprint of the component.


Question:

What approach do you suggest to fan out all signals, what PCB specifications do we need?


PCB specifications:

  • Number of layers: 4
  • Thickness: 1 mm
  • Blind vias: yes
  • Via in pad: yes
  • Dimensions: 25 x 28 mm


Thanks for your help & best regards

Rashid
